Users and integrators encounter Starknet to Ethereum withdrawals, Cairo bridge contracts, and ETH and ERC-20 transfers when using Starknet Bridge. Integrations and contract migrations through Starknet Bridge use this entry; changes to withdrawal proof verification, transfer failures and incident response at Starknet Bridge are included. Assets bridged through Starknet Bridge and their wallet interfaces need separate tags unless a change affects bridge contracts or withdrawals.
