• Network: Gravity Mainnet, chain ID 127001
• Public RPC: https://mainnet-rpc.gravity.xyz (supports debug_traceTransaction)
• Explorer: https://mainnet-explorer.gravity.xyz (all four contracts source-verified)
• Source: contracts from this repo at 7acbe662898945f1a989ad74e28cfbc8897f4a4b (contract sources unchanged at current master), solc 0.6.12+commit.27d51765, optimizer enabled with 10,000,000 runs, EVM version istanbul.
• Deployment method: the contracts were deployed through deterministic CREATE2 factories, so useTracesForCreationBytecode: true is set for all three entries. The creation bytecode is read from the CREATE2 frame of each transaction's callTracer trace:
  • SignatureChecker: deterministic deployment proxy 0x4e59b44847b379578588920ca78fbf26c0b4956c
  • FiatTokenV2_2 / FiatTokenProxy: CreateX 0xba5Ed099633D3B313e4D5F7bdc1305d3c28ba5Ed
• Verification type: default partial. The runtime bytecode is compared excluding the CBOR metadata, and the supplied metadata files are checked against the on-chain IPFS metadata hash.

Testing

Ran the official script locally against the public RPC:

yarn hardhat run --no-compile scripts/verifyMainnetTokenBytecode.ts --network mainnet
