ERC1967Proxy

BaseRegistered

An ERC-1967 upgradeable proxy pointing to an unverified implementation contract at 0xc1a9db4e8a16123f3397582a0eff555d01780149. The proxy delegates all calls (including hook callbacks) to the implementation. Hook behavior (beforeSwap, afterSwap, afterInitialize) cannot be analyzed because the implementation source is not verified on-chain.
