Timing

Bridged

There're no events emitted when a bridged token is minted or burned, jjy is trying to find out useful block logs about deposit and withdrawal. But deserializing transactions is still recommended.

Ref: https://github.com/nervosnetwork/godwoken-polyjuice/blob/main/solidity/erc20/SudtERC20Proxy_UserDefinedDecimals.sol

Considering adding deposit and withdrawal events on block generation, an issue has been committed

For now, we are going to use the current strategy to update bridged token distribution.

Native token

listen to {transfer} event from the contract Get logs from transactions

Now tokens are updated by logs
