withdrawer

Golang utility for proving and finalizing withdrawals from op-stack chains.

Usage

Install:

go install github.com/base-org/withdrawer@latest

Initiate a withdrawal on L2 by sending to the L2StandardBridge contract at 0x4200000000000000000000000000000000000010, and note the tx hash. Example on Base Goerli: 0xc4055dcb2e4647c37166caba8c7392625c2b62f9117a8bc4d96270da24b38f13.

Prove your withdrawal:

withdrawer --network base-mainnet --withdrawal <withdrawal tx hash> --rpc <L1 RPC URL> --private-key <L1 private key>

or use a ledger:

withdrawer --network base-mainnet --withdrawal <withdrawal tx hash> --rpc <L1 RPC URL> --ledger

Example output:

Proved withdrawal for 0xc4055dcb2e4647c37166caba8c7392625c2b62f9117a8bc4d96270da24b38f13: 0x6b6d1cc45b6601a30646847f638847feb629221ee71bbe6a3de7e6d0fbfe8fad
waiting for tx confirmation
0x6b6d1cc45b6601a30646847f638847feb629221ee71bbe6a3de7e6d0fbfe8fad confirmed

After the finalization period, finalize your withdrawal (same command as above):

withdrawer --network base-mainnet --withdrawal <withdrawal tx hash> --rpc <L1 RPC URL> --private-key <L1 private key>

Example output:

Completed withdrawal for 0xc4055dcb2e4647c37166caba8c7392625c2b62f9117a8bc4d96270da24b38f13: 0x1c457f1992f48f1f959ceaee5b3c7e699a26f6f05d93997d49dafe703fd66dea
