Historical Significance

One of 1,203 byte-identical deployments of a minimal owner deposit wallet, the optimizer-ON build of the canonical depositwallet contract.

Context

Compiled with soljson-v0.1.3 (optimizer ON); exact match of both the 215-byte runtime and 249-byte creation bytecode. The optimizer-ON sibling of depositwallet-0x2641015c (optimizer OFF, 543B).

Exact bytecode match. Runtime: 215 bytes (byte-for-byte). Creation: 249 bytes (byte-for-byte). Compiled with soljson-v0.1.3+commit.028f561d, optimizer ON. Optimizer-ON sibling of the depositwallet-0x2641015c proof (optimizer OFF, 543B): same canonical source, different compiler setting, distinct on-chain bytecode and a separate cluster. The Deposit event topic keccak("Deposit(address,uint256,uint256)") is present on-chain.
