The Arbitrary Message Bridge between the Ethereum Mainnet and the xDai chain now requires a request-and-claim scheme to transfer data from the xDai chain, and some users and applications may want to use a manual process to gather the oracles confirmations and send them to the AMB contracts on the Mainnet side.
Below is the list of actions that can be executed in BlockScout and Etherscan, or, if you are familiar with the contract interaction through Web3 provider, it can be done by importing the contract's ABI to your application.
Find the first transaction which initiated message passing through the AMB bridge and go to the logs generated during the transaction execution. The
encodedData argument emitted with the
UserRequestForSignature event will be used in the next steps.
Go to the AMB helper contract and call
getSignatures there with the encoded data from the
UserRequestForSignature event. It will produce a blob with signatures.
Pass the encoded data and the signatures to the Arbitrary Message Bridge contract (
0x4C36d2919e407f0Cc2Ee3c993ccF8ac26d9CE64e) on the Ethereum Mainnet and press the "Write" button to send the transaction.
