This page documents the legacy Whitechain Layer 1 (L1), mainnet chain ID
1875. The L1 is live and producing blocks. It is a separate chain from the Whitechain Layer 2 (L2) documented in the rest of these docs, and it migrates to the L2 at L2 Mainnet launch. To verify a proxy contract on the L2, see Verify a proxy contract.1875) today. At L2 Mainnet launch it begins serving the L2 explorer, and the L1 explorer moves to https://legacy-explorer.whitechain.io, where the proxy verification form is at https://legacy-explorer.whitechain.io/verify-contract/proxy. From then on, verify an L1 proxy at the legacy hostname; verifying at explorer.whitechain.io submits against the L2. See Endpoint and domain changes.
Please Note: the implementation contract must be verified first for proxy contract verification.
