which could be used to parse logs of 0x6baefb2f6ecfb912eb0b5791a691c0af63ac6e85

Maybe we should add a function to recognize and parse logs of a proxy contract

Proxy contract workflow:

Find contract that has implemention abi
Query the proxy contract address and query the proxy contract abi merge into current contract
Use the merged abi parse data

blockscout/blockscout#3153

zmcNotafraid · 2023-02-02T13:35:31Z

For SmartContract grapqh field, we add below four field

 implementation_name: string
 implementation_fetched_at: datetime
 implementation_address_hash: address
 implementation_abi: list json

So if the proxy smart contract have implementation_address_hash value. You can query it's implementation contract's abi by

query {
      smart_contract(
        input: { contract_address: "0xbFE9D9Da5D5AD0f79B0cC7800a685Fc87cAe2884" }
      ) {
       implementation_abi
      }
    }

Could you take over this feature design to deliver information of proxied contract on the proxy contract page @Danie0918

The goal of this feature is to ameliorate the workflow of viewing a targeted contract.

The progress of calling a proxied contract is user -> tx -> proxy contract -> internal tx -> target contract, so the tx links to the proxy contract instead of the target contract, which executes the actual business.

With this feature, updates in the target contract are expected to be found easily.

Danie0918 · 2023-02-03T08:52:34Z

Ok,I'll take it over after finfish the PRD of CKB Explorer.

proxy contract's event logs
use /accounts/implementation_address_hash/logs api
proxy contract's erc20 records

query {
  token_transfers(
        input: {
          to_address: implementation_address_hash
    }
 }

Keith-CY · 2023-03-23T16:08:05Z

proxy contract's event logs
use /accounts/implementation_address_hash/logs api

proxy contract's erc20 records
query {
  token_transfers(
        input: {
          to_address: implementation_address_hash
    }
 }

Will /accounts/implementation_address_hash/logs only return logs trigger by proxy contract instead of all logs emitted by implementation contract?

I ask this because /account/{address}/logs is expected to fetch all logs of an account before.

Can we use graphql api instead of this json api.

Due to the workload of interface adjustment exceeding expectations, the development and joint debugging work is suspended.
