👩‍👩‍👧‍👦 WHOM: Global consumers with just a few thousand dollars and no technical background.

💎 WHAT: A digital wallet for crypto assets, investment and identity. Consumers can buy crypto assets , then trade between multiple platforms. They can earn fixed-rate interests or actively invest for higher returns. can hold or .

🤯 MAGIC

• Earn for the first million users.

• No emails, SMS, passwords or government documents necessary.

• Seamless between assets from Bitcoin, Ethereum or .

🔨 HOW

• Many offer 10% yields, offer 10%, and offer 20%.

• Assets and keys are secured on blockchain; and .

• Harmony supports non-custodial and trustless transactions in 2 seconds and at less than $0.01 fees.

🚀 WHEN: Product launch in 2021 Q3 with 1000 users, then 10k users in Q4 with each wallet holding $1000. A prototype with minimal features on mainnet in July.

💡 Terms

• Non-custodial: no network, software, developers, government or even Harmony control your fund.

Security Goals

ONE Wallet is designed with these goals in mind for security:

Social (people)

• Resilient. Funds are recoverable through time locks and multiple safety nets. No single point of failure such as thefts, cracks, loss, censorship or coercions is catastrophic.

• Sufficient. All steps are well defined without delegating to hardware devices or seed phrases in safety boxes. Users do not need any passwords or rely on biometrics.

• Anonymous. An account is a fresh cryptographic hash, not tied to existing systems or real-world identity. Derived paths support multiple public keys to protect privacy.

Smart (code)

• Composable. One-time or low-entropy passwords are useful for small funds. Multiple authentications can independently boost protection thresholds against brute-force.

• On-chain. A decentralized network with high stakes and fast finality validates all transactions. Its platform has sustainable incentives and open governance to evolve.

• Programmable. Operations can call third-party contracts, store history of states, or upgrade its code. Complex applications may use oracles of time, locations and events.

Hard (math)

• Self-Sovereign. No third parties, government documents, designated guardians, backup servers or hardware enclaves are necessary. Users have full custody and self control.

• Air-Gapped. Key-loggers and man-in-the-middle attacks are minimized. The full parameters of transactions are easy to verify and approve without cables or cameras.

• Verified. Trusted are only open source and hardened cryptography. Formal verification, through logical frameworks, assures end-to-end security beyond tests and audits.

Tradeoffs

There may be conflicts, tradeoffs or impracticality of the goals above. Here's our rule of thumb:

1. Toward validating our innovation with 10k users (each with $100 assets), focus on these three goals: sufficient, resilient and composable.

2. Toward adopting our product with 1m users (each with $1k assets), differentiate with these three goals: on-chain, self-sovereign and air-gapped

Download SafePal Mobile Apps

SafePal mobile apps can be downloaded from PlayStore and AppStore following the instructions.

Quick Start

Ledger Nano X and Nano S

The Nano X and Nano S are hardware wallets created by Ledger. A hardware wallet stores the private keys to Harmony tokens on a separate device, making it much harder for malicious parties to steal them. In fact, the private keys never leave the Nano wallet itself, so they will remain secure even if the device is connected to a compromised computer. As long as you follow best practices when using your Nano, it is virtually impossible for an attacker to steal your funds.

Using Harmony hardware wallet on the Ledger requires a few things. You will need:

• Your Ledger

Download Harmony CLI tool

1. For Linux

Enter the following command into your shell of choice:

curl -LO https://harmony.one/hmycli && mv hmycli hmy && chmod +x hmy

2. For MacOS

hmy depends on some dynamic libraries, hence we recommend using the shell wrapper. Enter there commands into your terminal:

curl -O https://raw.githubusercontent.com/harmony-one/go-sdk/master/scripts/hmy.sh
chmod u+x hmy.sh
./hmy.sh -d

Now you can use hmy.sh as a wrapper over hmy and you should assume that all references to hmy in these documents refer to hmy.sh. For example, the command ./hmy becomes ./hmy.sh -- .

3. Compiling from source

If you are interested in compiling from source, then the process is more involved.

Steps:

1. Clone the repository at the same level as the main Harmony repo:

cd $(go env GOPATH)/src/github.com/harmony-one
ls
bls harmony mcl
git clone https://github.com/harmony-one/go-sdk.git

1. Then setup the build flags:

source harmony/scripts/setup_bls_build_flags.sh

1. Call make in the go-sdk repo. This builds a binary named hmy:

cd go-sdk
make

Congratulations! You can now use the binary to run the CLI.

Introduction

hmy is the official Command Line Interface (CLI) provided by Harmony. You can use it as a local wallet and as a way to interact with your Ledger Nano device. The hmy CLI is completely open-source. You can track its development and post any issues encountered and your feature suggestions here.

Features

With the hmy CLI you can create a wallet, check your balance, send signed transactions to the Harmony blockchain, look up previous transactions, recover keys from previous mnemonics, create new keystores, and create new BLS keys.

Supported Platforms

• OSX: main development platform

• Linux: tested

• Windows: tested/working under Windows Subsystem for Linux (WSL)

Release information

We will always upload the latest production release on github and announce future uploads in pre-production releases.

Perhaps the most important feature of the hmy CLI is the ability to create and send signed transactions to the Harmony blockchain.

Overview

Sending a transaction

Using the Binary:

./hmy transfer --node="<endpoint-address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase

Using the Shell Wrapper:

./hmy.sh -- transfer --node="<endpoint-address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase

Example:

./hmy --node="https://api.s0.t.hmny.io" \
 transfer --from one1yc06ghr2p8xnl2380kpfayweguuhxdtupkhqzw \
 --to one1q6gkzcap0uruuu8r6sldxuu47pd4ww9w9t7tg6 \    
 --from-shard 0 --to-shard 1 --amount 12.5 --chain-id mainnet --passphrase mypassword

Checking the transaction hash

Check for finality of the transaction by using the transaction hash like so:

Using the Binary:

./hmy blockchain transaction-receipt <transaction_id> --node="<endpoint-address>"

Using the Shell Wrapper:

./hmy.sh -- blockchain transaction-receipt <transaction_id> --node="<endpoint-address>"

Example:

./hmy --node="https://api.s0.t.hmny.io" \
 blockchain transaction-receipt \
 0x599793f313ee17566f8d09728b9d043b8e26135ddce86beeee13f98767d452f7

Detail

ChainIDs

Let's first check what chain-ids are available for us to use, we can do that easily with:

Using the Binary:

./hmy blockchain known-chains

Using the Shell Wrapper:

./hmy.sh -- blockchain known-chains

Example:

./hmy blockchain known-chains

[
  "mainnet",
  "testnet",
  "devnet"
]

Notice that the output is pretty printed JSON, most outputs of hmy are JSON encoded and hmy defaults to showing it nicely indented. Sometimes though you might want to turn that off, you can do that for any command with the flag --no-pretty.

By default, hmy assumes the testnet chain-id; override that with the --chain-id flag

Our first transaction

We'll use the transfer subcommand of hmy to send a transaction.

./hmy transfer
Error: required flag(s) "amount", "from", "from-shard", "to", "to-shard" not set

Notice that simply invoking the transfer subcommand gave us an error message about certain flags not being set. We'll need to provide legitimate values for these flags for our transaction to proceed successfully. Reading off the flags in the error message from left to right, the semantic meanings are as follows:

• amount: The quantity of Harmony One token to transfer from the senders to the receiver

• from: The sender's one address

• from-shard: Shard from which sender's balance will be drawn from

• to: Receiver's ONE address

• to-shard: Shard in which receiver will receive the amount sent by the sender

• passphrase: your wallet passphrase, which is prompted when you hit enter (or you can use a txt file with password and add it: --passphrase file.txt)

A sharded blockchain is a new kind of blockchain architecture where the network is partitioned into sub-networks called shards. Sharding is one of the distinguishing features of Harmony and it is key to solving the traditional scalability problems encountered in other blockchain protocols.

Note: The same ONE address will have a different balance in each shard. Currently Harmony mainnet has four shards while testnet has three shards. Sending a transaction from one shard to another is called a "cross-shard transaction."

Thus, a correct usage of transfer looks like:

Using the Binary:

./hmy transfer --node="<endpoint-address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase

Using the Shell Wrapper:

./hmy.sh -- transfer --node="<endpoint-address>" \
 --from <ONE_address> --to <ONE_address> \
 --from-shard <shard> --to-shard <shard> \
 --amount <amount> --chain-id <chain-id> --passphrase

Example:

./hmy transfer --node="https://api.s0.t.hmny.io" \
 --from one1yc06ghr2p8xnl2380kpfayweguuhxdtupkhqzw \
 --to one1q6gkzcap0uruuu8r6sldxuu47pd4ww9w9t7tg6 \
 --from-shard 0 --to-shard 1 --amount 10 --chain-id mainnet
{"transaction-receipt":"0x455f98a3aa11ef50ee5cc5ac8bbd79e04f2fe353180bb7e25fc6c921fc8fdc83"}

Try out your transaction with the flag --dry-run, this flag tells hmy to create, cryptographically sign the transaction but not actually send it off. Sender's balances are checked and the output is a JSON dump of the signed transaction.

Signing and sending a transaction is very quick, about 2 seconds maximum. The actual sending of the transaction is done via an RPC (Remote Procedure Call), you'll notice that we did not explicitly say where to send the transaction to. This is because the default destination of the RPC call goes to http://localhost:9500, the default HTTP RPC server running when you start a local harmony blockchain. For real world usage though, you'll want a different location. You can control that with the --node flag (see the top of this page for an example).

Result of the transaction

Once an RPC machine receives a transaction, it sends you back a transaction hash. This transaction hash is the key identifier used when querying the blockchain for transactions.

We can pull down details of the finalized transaction with ./hmy blockchain transaction-receipt as well:

Using the Binary:

./hmy blockchain transaction-receipt --node="<endpoint-address>" <transaction-hash>

Using the Shell Wrapper:

./hmy.sh -- blockchain transaction-receipt --node="<endpoint-address>" <transaction-hash>

Example:

./hmy blockchain transaction-receipt \
    --node="https://api.s0.t.hmny.io" \
    0x25dd32397b5a69146b2dc3bbdc8ef8aae271e9b12a36c6dff1eb8995cac9dcba

  }
}

You can tell hmy to wait until transaction confirmation by providing a positive integer value to flag --wait-for-confirm. For example, --wait-for-confirm=10 will try checking the receipt of the transaction for 10 seconds.

New Wallet

Using the Binary:

./hmy keys add <account-name> [--passphrase]

Using the Shell Wrapper:

./hmy.sh -- keys add <account-name1> [--passphrase]

Example:

./hmy keys add test-account --passphrase

This creates a keystore at the following directory:(hmy keys location)/account-name1/UTC--2019-09-16T21-25-35.297331000Z--678e7ea3dcb5f4e9724c0e761843572f10c49b73

When creating keys this way, hmy will ask you to provide a passphrase.‌ Make sure you keep track of this passphrase for future use because the passphrase is used to decrypt the keystore when signing transactions. Also make sure you save the seed phrase, also called a mnemonic.

To know where your wallet file has been created, run the following command:

Using the Binary:

./hmy keys location

Using the Shell Wrapper:

./hmy.sh -- keys location

You can check the list of wallets (local accounts) with the following command:

Using the Binary:

./hmy keys list

Using the Shell Wrapper:

./hmy.sh -- keys list

Import Wallet

Importing a Keystore

‌You might have an existing keystore made by Harmony's old wallet.sh program that ends with ".key" in the file name (example):

one16qsd5ant9v94jrs89mruzx62h7ekcfxmduh2rx.key

Or that starts with "UTC" in the file name (example):

UTC--2020-01-15T01-02-06.606670000Z--9689a0711642bf08ea92ed98d552f0c1b8c8cefb

Both these files can be imported into hmy using the command import-ks as shown below.

Using the Binary:

./hmy keys import-ks <absolute_path_to_keystore> --passphrase

Using the Shell Script:

./hmy.sh -- keys import-ks <absolute_path_to_keystore> --passphrase

Examples:

./hmy keys import-ks /home/harmony/one16qsd5ant9v94jrs89mruzx62h7ekcfxmduh2rx.key --passphrase
./hmy keys import-ks /home/harmony/UTC--2020-01-15T01-02-06.606670000Z--9689a0711642bf08ea92ed98d552f0c1b8c8cefb --passphrase

‌Keep in mind that you should know the passphrase associated with the imported keystore and pass it as a parameter as shown in the commands above. For keystores created by Harmony's wallet.sh, the default passphrase is an empty string; this matters for signing transactions.‌

Importing a Private Key

Sometimes you might have a secp256k1 private key, such as the one generated from the following command:

openssl ecparam -genkey -name secp256k1 -text -noout -outform DER | xxd -p -c 1000 | sed 's/41534e31204f49443a20736563703235366b310a30740201010420/PrivKey: /' | sed 's/a00706052b8104000aa144034200/\'$'\nPubKey: /'

You can import the key with an optional name and passphrase

Using the Binary:

./hmy keys import-private-key <secp256k1_private_key> [wallet_name] [--passphrase]

Using the Shell Script:

./hmy.sh -- keys import-private-key <secp256k1_private_key> [wallet_name] [--passphrase]

Example:

./hmy keys import-private-key b8798ca0a56ce16517ea37c6b1229cbb67cf0e022c423b044fe8f537830d8be5 my_wallet_name_here --passphrase

If no account name is provided, a random word concatenated with -imported will be used. If no passphrase is provided, the default passphrase will be used (which is blank). Note that the CLI currently only supports importing secp256k1 private keys.

Importing a Mnemonic Phrase

You can recover lost wallet keys by entering the mnemonic words you received (and hopefully saved) when creating it:

Using the Binary:

./hmy keys recover-from-mnemonic [wallet_name]

Using the Shell Script:

./hmy.sh -- keys recover-from-mnemonic [wallet_name]

Example:

./hmy keys recover-from-mnemonic nameofyourkey

Delegating to a Validator

You can delegate tokens to a validator using the following command:

./hmy --node="https://api.s0.t.hmny.io" staking delegate \
    --delegator-addr [ONE ADDRESS] --validator-addr [ONE ADDRESS] \
    --amount [AMOUNT] --passphrase

The CLI will ask for the passphrase for the delegator-addr keystore file.

--delegator-addr is the ONE address of the delegator (string)

--validator-addr is the ONE address of the validator (string)

--amount is the number of ONE tokens to delegate to the validator (float)

Undelegating from a Validator

You can un-delegate tokens from a validator using the following command:

./hmy --node="https://api.s0.t.hmny.io" staking undelegate \
    --delegator-addr [ONE ADDRESS] --validator-addr [ONE ADDRESS] \ 
    --amount [AMOUNT] --passphrase

The CLI will ask for the passphrase for the delegator-addr keystore file.

--delegator-addr is the ONE address of the delegator (string)

--validator-addr is the ONE address of the validator (string)

--amount is the number of ONE tokens to un-delegate (float)

Collecting Rewards

You can collect your block rewards with the following command:

./hmy --node="https://api.s0.t.hmny.io" staking collect-rewards \
--delegator-addr [ONE ADDRESS] --passphrase

The CLI will prompt your for the passphrase of the delegation account.

--delegator-addr is the account to collect rewards for

Generate Markdown Documentation

if you want a full list of commands the hmy tool knows in markdown format, please run the following command:

./hmy docs

Then in the same directory, hmy creates a directory named hmy-docs in which you can find all markdown files for the commands and subcommands.

Delete Account

Deletion of a one account is possible by issuing the below command

 ./hmy keys remove [ACCOUNT-NAME]

The easiest way to get detailed help is to use the cli itself. For example below is the cookbook which gives an overview of various commands.

./hmy cookbook --node="https://api.s0.t.hmny.io"

#Cookbook of Usage

#Note:

#1) Every subcommand recognizes a '--help' flag
#2) If a passphrase is used by a subcommand, one can enter their own passphrase interactively
#   with the --passphrase option. Alternatively, one can pass their own passphrase via a file
#   using the --passphrase-file option. If no passphrase option is selected, the default
#   passphrase of '' is used.
#3) These examples use Shard 0 of Open Staking Network as argument for --node

#Examples:

#1.  Check account balance on given chain
./hmy --node="https://api.s0.t.hmny.io" balances <SOME_ONE_ADDRESS>

#2.  Check sent transaction
./hmy --node="https://api.s0.t.hmny.io" blockchain transaction-by-hash <SOME_TX_HASH>

    --from-shard 0 --to-shard 1 --amount 200 --passphrase

#5.  Sending a batch of transactions as dictated from a file (the `--dry-run` options still apply)
./hmy --node="https://api.s0.t.hmny.io" transfer --file <PATH_TO_JSON_FILE>
#Check README for details on json file format.

#6.  Check a completed transaction receipt
./hmy --node="https://api.s0.t.hmny.io" blockchain transaction-receipt <SOME_TX_HASH>

#7.  Import an account using the mnemonic. Prompts the user to give the mnemonic.

Outgoing transactions

Since there is no shard selection in the Trust Wallet UI, all transactions will originate from shard 0 and will be sent to shard 0.

For more details, please see these example cross-shard transactions using Trust Wallet:

What to do if you receive funds in a shard other than shard 0 when using Trust Wallet?

You will need to export the account in which you received the funds and import it to another wallet such as the CLI or Math Wallet.

Example Using Math Wallet:

1. Open Trust Wallet app

2. Click on "Settings" on the bottom right

3. Click on "Wallets"

Go to and download the file that is appropriate to your operating system (1wallet-linux, 1wallet-macos, or 1wallet-win.exe).

• I saved it in my downloads folder, but you can save it anywhere.

• Open your Terminal (I'm a Mac user), and run the following commands:

Now that you have installed your CLI 1Wallet, you can do several things including:

The first step is to scan the QR code.

Once you have done that, you can run the next command using the 6 digit authenticator code and a recovery address of your choice to create your 1Wallet.

You should see a screen like this on your Terminal (yes, do you like my Matrix themed Terminal?):

After that you can try to send a small amount of tokens to your newly created 1Wallet and in general test some of the other commands and functionalities.

Here is the list of failed transaction messages which can be checked by querying your transaction hash, checking the transaction hash on explorer or checking the blockchain pool transactions.

Here is how with the hmy cli :

1Wallet:

Creating Your ONE Wallet

First, make sure to have Google Authenticator installed on your mobile device. Click on button Create and a QR Code similar to the image below will show up. Scan this QR Code using Google Authenticator app and type the random 6-digit code.

After inputing the 6-digit code you will be redirected to a new window. Fill the recovery address and click on Create Now.

If everything went alright you should see your wallet created:

balajis.com @balajis · Jun 11 Replying to @matthew_d_green Yes. But here’s a possibly dumb workaround:

1) A listens for events on chain 2) B sends a decryption request for resource to A’s address 3) A returns decrypted version, re-encrypted with B’s public key, if in a valid time window

Sort of like multisig with restrictions?

nick.eth @nicksdjohnson · Jun 11 Replying to @AutismCapital 2FA only works when you have a central service that controls access to your data. The wallet equivalent of 2FA is a hardware wallet.

stephen tse | s.one @stse · Jul 4 why can't public and decentralized platforms do 2fa services?

Pedro Gomes 🦇🔊📲 @pedrouid · Feb 13 Replying to @zmanian I think it’s also due to user demand

A pure wallet would essentially just display different signing authorization screens without a specific use-case

Cryptocurrency wallets on the other hand transfer funds, show balances, etc

stephen tse | s.one @stse · Jul 4 how about separating wallets from authenticator? with one-time-password (otp) like google auth

On June 24, 2021, we announced the , including the $4M in incentives for liquidity mining, Kashi, and also the $1M hackathon focused on onboarding software engineers from traditional finance to DeFi. Today, we’ll show you how to participate in the upcoming liquidity mining event on Harmony.

In this post, we’ll show you:

1. How to add the Harmony Network to your metamask

2. How to use the Harmony Bridge with Sushi

3. How to Yield Farm Sushi on Harmony

We’ve also included a simple infographic to use as a quick reference.

How to Add the Harmony Network to your Metamask

Step 1: Go to app.sushi.com

Step 2: Connect your wallet

Step 3: Click the button that says “Ethereum” in

the top right-hand corner

Step 4: Select the Harmony Network and if you don't see it, complete the steps below

Step 5: Approve the switch in your wallet, and done!

How to Use the Harmony Bridge with Sushi

How to Yield Farm Sushi on Harmony

Step 2: Switch your network to Harmony

Step 3: Click the Yield tab to check which farms are available on the Harmony network that you would like to join.

Step 4: Click the Pool tab

Step 5: Select the tokens for a valid token pair you wish to add liquidity to *Note, when adding liquidity to a pair, both sides of the pair need to have exact monetary value.

For example: [$100 1USDC / $100 ONE], would be [100 USDC / 1525 ONE] at time of writing

Step 6: Add the amount of tokens you wish to add to the pool of the first token. The Sushi platform will automatically add the equal monetary value of liquidity to the second asset, given there is sufficient balance

Step 7: Approve Sushi to access your tokens from your wallet

Step 8: Click Supply, then Confirm Supply in the popup

Step 9: Approve the transaction and relevant fees from your wallet, you will now receive your liquidity pair or LP tokens

Step 10: Once the transaction approves, click the Yield tab and click the yield farming pair you wish to join, you should see your Wallet Balance now displays your received LP tokens

Step 11: Input the amount of LP tokens you wish to add to the farm or click MAX

Step 12: Click Approve

Step 13: Allow Sushi to spend your SLP tokens from your wallet

Step 14: Click Deposit

Step 15: Confirm the transaction and the relevant fees from your wallet

WONE Rewards

The rewards for Sushi staking are in Wrapped ONEs on Harmony. Please add this contract address as a token to your Metamask:

0xcF664087a5bB0237a0BAd6742852ec6c8d69A27a

You may use Sushi Swap itself to exchange between WONEs and ONEs.

1. What does Expires In mean?

1wallets have an expiration date. It means that once the expiration date is reached, all your funds will be automatically sent to the recovery address you set.

2. What does Daily Limit mean?

The daily limit for 1wallet is set to 1000 ONE's. This means you cannot transfer more than this amount daily.
