Use this page to find a token address you should have after the bridge.
Here you can specify the network by pressing its button. If your token is on Binance or Ethereum, it can help you to avoid confusion. You can also set a filter by a token type if you know it.
Search a token you plan to bridge. You can enter its address / symbol / name.
Click on the paired token address, and it will lead you to the token page.
There are tokens named the same in the different networks, but they always have different addresses. Compare token address and name to your token data to avoid a confusion.
If you bridge a token from the network where it was issued, you receive a mapped token. Usually it has a prefix in the name that indicates a wrap.
If you have a token on Harmony that is originated from Binance or Ethereum, you can bridge it back only to the network it came from. As a result you’ll get the origin token.
Frequently bridged tokens:
ONE
If you bridge ONE from Harmony to Binance, your ONE will have a different address on Binance: 0x03fF0ff224f904be3118461335064bB48Df47938
If you bridge ONE from Harmony to Ethereum, you receive 1ONE token with the address 0xD5cd84D6f044AbE314Ee7E414d37cae8773ef9D3
If you bridge ONE from Binance or 1ONE from Ethereum, you get Native Harmony ONE on Harmony.
BNB
If you bridge BNB from Binance, you get bscBNB on Harmony.
ETH
If you bridge ETH from Ethereum, you get 1ETH in Harmony wallet.
BUSD
If you bridge BUSD from Ethereum, you get 1BUSD on Harmony.
If you bridge BUSD from Binance, you get bscBUSD on Harmony.
DAI
DAI on Ethereum - 1DAI on Harmony
USDC
Ethereum USDC - 1USDC on Harmony
USDT
You can find your token from your final step transaction if it’s correctly displayed (sometimes there are delays in data representation).There is a token symbol near the amount in “Tokens transferred”/ ”Token transfers” section that leads to the token page.
You can also look for the token in a token list on your wallet address page in the target chain explorer (it also can take some time for a token to appear).
Click on the token symbol, and you’ll see all necessary token information.
Don’t forget, that address should be in ETH style (starting 0x...). For Harmony Explorer, there is a switcher in the top right corner.
If you can’t find your token there, please use this page to find a token address you should have after the bridge.
After you find your token, add it to your wallet as shown here. You can avoid this process if you use Add token to Metamask button on the bottom your bridge operation page after operation is completed:
Check that you add token to a receiver wallet of your operation and the wallet is connected to the correct network.
LayerZero is a cross-chain bridge that allows exchange of crypto assets (e.g., fungible/non-fungible tokens, stablecoins) between Ethereum or Binance Smart Chain and Harmony blockchains.
The Bridge is used to migrate assets from one chain to another. If you have assets on Ethereum or Binance Smart Chain, you can use the bridge to move them to Harmony blockchain and get corresponding assets on Harmony. LayerZero also allows redemption of the exchanged assets back at any time.
LayerZero Bridge is accessible here.
There is bridge process step-by-step explanation
You need to be able to open your wallet in the network you sent your tokens to. Check that there are no network restrictions that prevents you from it. Also check if there is no limitations on a token type you can receive. Never send tokens to an exchange account!
No, bridging to contract address directly is not supported. It might result in permanent loss of your tokens.
Please refer to this page to find out.
You will need identify the contract address of the asset your just bridged looking at https://bridge.harmony.one/tokens and add it into metamask

You can find the list the bridged assets here
Assets are mapped 1:1. For example, 10 BUSD on Ethereum after bridging will be available as 10 1BUSD on Harmony. Here, “1BUSD“ is the token symbol of the token on Harmony corresponding to “BUSD“ token symbol on Ethereum.
Same 1:1 mapping holds true for Binance Smart Chain. However, the assets from two different parent chains (Ethereum or Binance Smart Chain) after bridging will be represented using different bridged assets on Harmony. For instance, 5 Binance Smart Chain BUSD after bridging will be available as 5 bscBUSD on Harmony. Here, “bscBUSD” is the token symbol of the token issued on Harmony corresponding to “BUSD” token symbol on Binance Smart Chain.
And, the 1BUSD and bscBUSD on Harmony chain are not interchangeable, meaning one cannot bridge BUSD from Ethereum to Harmony and then withdraw it on Binance Smart Chain. Same for other tokens.
There is no limit on the amount of tokens that can be bridged.
Yes: you can bridge tokens back and receive back the same amount of the original token there. For example, you bridged USDC from Ethereum to Harmony and got 1USDC token on Harmony. At any time you can bridge 1USDC back to Ethereum and receive USDC token.
No, Ethereum bridged tokens can only be sent back to Ethereum. Same applies for Binance bridged tokens.
No, do NOT send bridged tokens directly to other blockchains or exchanges. This will not work and might result in permanent loss of your tokens. Bridged tokens can only be used on Harmony network. The only way to send them out is bridging them back.
Yes. You can transfer the bridged tokens to other users, and they can redeem them back to their Ethereum or Binance accounts. This is possible because when you lock your token, it gets pooled into a bridge smart contract from which any redeem request can be serviced without tying the locked tokens and redemption to a specific user account.
Once you use LayerZero to transfer your original tokens to Harmony, the original tokens get stored and locked in the LayerZero contracts: you do not own those tokens on Ethereum or Binance anymore. You receive the same amount of tokens on the Harmony blockchain.
No: The supply of the original token never change as a result of using LayerZero: LayerZero bridge locks a certain amount of a token on Ethereum blockchain (essentially taking it out of circulation) and mints the exact same amount of tokens on the Harmony blockchain, that represents in all respects the original token (i.e. regenerating the locked supply). As a result, the circulating supply of the original token will stay the same: it's just split across two different blockchains instead of one.
It depends on which blockchain you want transfer assets from. If it is from Harmony blockchain, you need ONE tokens, if it is from Ethereum you need ETH tokens, from Binance Smart Chain (BSC) BNB tokens and so on.
Cost of the bridge operation consists of the LayerZero bridge fee and costs of transactions. You'll see the page with the fee information that you need to confirm before the operation. Transaction fee depends on the chain gas prices and are confirmed in Metamask before the transaction. LayerZero fees are calculated dynamically based on Oracle and Relayer prices for the destination chain. They are transferred in the same transaction as the bridges amount. Fees are paid in native tokens of the first chain, so if you transfer any token from Ethereum, you pay fees by ETH token, ONE for Harmony and BNB for Binance.
You can find the operation details on your operation page. It's the page you see when you perform the operation on the LayerZero bridge site. Every bridge operation is associated with a unique operation id, which is shown on the page. You can find links to transactions of the operation steps and the status of each step. Also, you can always find your operation in the bridge operation explorer. Use "My transaction" option to see only operations for your connected Metamsk account.
If your transaction is pending for too long, you can manage it via your wallet. We can’t make it faster or cancel it. If the transaction is on Harmony side, make sure you use recommended settings for Harmony network.
Normally it takes less than 20 minutes per each step of the bridge operation. Delays are also possible, but they won't affect your funds. If your operation is in progress for more than an hour, you can fill in the support form and include you problem description. Note that your request will be ignored if you send it earlier.
Bridge does not swap tokens, it only provides wrapped tokens. For the token that you bridged, you have received wrapped token to your account. To find out which one, you can refer to this page.
Note that:
Bridge is not a swap, and you won't receive ONE if you weren't bridging ONE token.
A token address is never the same in the different networks, even when a symbol is the same.
If you don't see that token in your account, and add it to your wallet to see the correct balance as shown here. If you have problems with finding or adding a token, please ask for help in community groups.
If you added a token and tokens aren’t shown, check that:
You added a token to the receiver wallet of your operation.
The receiver address of your operation is correct. If you found out that you made a mistake in the address, we can’t help you with that. You can reach your funds only if you have access to the wallet.
The receiver wallet is connected to the correct network. For example, if you bridged tokens to Harmony, you need to be connected to Harmony mainnet.
You’ve added a token that you really received. Check the transaction data.
Tokens haven’t been transferred after the bridge.
If a correct balance isn’t shown after you added a token, and you have double-checked everything, fill in the support form and include you problem description. It’s required to include a token address you added and a wallet you added it to.
Please fill in the support form and include you problem description.
There can be many possible causes. Sometimes the reason is clear from the error message (for example, low balance, not enough tokens to cover gas). Often there is a problem with the wallet connection. Try these steps to solve it:
Make sure your browser and the wallet extension are updated to the latest version
Make sure that your browser doesn’t block pop-up windows.
Try to clear the cache and relogin.
Check here if your wallet is set up correctly.
Try using another browser or/and wallet extension.
If you use a mobile version, try it on the desktop.
If you’ve checked your settings, but you still have errors, please share your problem in the #support or #bridge Discord channel.
Unfortunately, your tokens are permanently lost and not recoverable.
If you can’t open your wallet in the network where your tokens were sent, we can’t assist. You can try to reach a support of the service that gave you this account.
Unfortunately, we can't help in such case. We don't have access needed to transfer tokens between accounts.
You can address your question to Harmony community in Discord or Telegram. Please beware of scammers. Remember, admins never DM you first. Please refer to our FAQ first.
