Without UI

It is possible to move Dai and xDai using a wallet rather than through the UI. This method is supported by all wallets that support ERC20 transfers (e.g., TrustWallet, MetaMask). Here we use NiftyWallet.

Token address for reference:

TokenBridge addresses for reference (where you send the asset to transfer)

  • Mainnet TokenBridge (Dai -> xDai): 0x4aa42145Aa6Ebf72e164C9bBC74fbD3788045016
  • xDai TokenBridge (xDai -> Dai): 0x7301CFA0e1756B71869E93d4e4Dca5c7d0eb0AA6

Transfer Dai from the Ethereum Mainnet to the Gnosis Chain

  1. Connect to the Ethereum Mainnet and locate DAI in your webwallet.

  2. Enter in the following:

    1. TokenBridge Address as the recipient: 0x4aa42145Aa6Ebf72e164C9bBC74fbD3788045016
    2. Amount to Send
    3. Submit the transaction
  3. Wait for the relay confirmation from the bridge validators. This may take several minutes.

  4. Set your wallet to the Gnosis chain and check your balance.

Transfer xDai to DAI from the Gnosis chain to the Ethereum Mainnet


The following demonstrates interaction with contract methods using BlockScout and Etherscan

  1. Send xDai coins to the Token Bridge address 0x7301CFA0e1756B71869E93d4e4Dca5c7d0eb0AA6 on the Gnosis Сhain using any wallet software.

  2. Wait for the transaction confirmation on the Gnosis chain (5 seconds).

  3. Copy the transaction hash of the confirmation and connect to the Ethereum mainnet.

  4. Visit the helper contract:

  5. In the getMessageHash method field add the following information from your originating transaction and press the Query button. The method will return a hashed message.

  • DAI recipient (typically the transaction sender but may differ if the ‘relayTokens’ functionality is used)
  • Value (in Wei - do not include fees, only amount sent (Wei converter at
  • Originating transaction hash
  1. Copy the message hash and paste into the getMessage method. If you receive 0x0 it means either the bridge oracles did not send a confirmation for the withdrawal yet or the data entered in the step 3 is incorrect. Double check the info and if it is correct you will eventually receive the message.

  2. Once you receive the message, use the message hash again this time with the getSignatures method. It will return a blob with packed signatures provided by the validator. The method could fail if not enough signatures are collected.

  1. Go to Etherscan and connect a web3 wallet:

  2. Enter the message (from getMessage method above) and the signatures blob to the executeSignatures method, press the Write button and complete the transaction with a Web3 wallet. If the method reverts, the withdrawal was likely already executed. You can check all input for the recipient here:, where the recipient's address follows after “a=“.

Once you have written to the contract method, a View your transaction button will appear. Click to view the pending transaction.
