Wallet proxy stub generated by the Mist Wallet factory. Forwards all calls via CALLCODE to the master Ethereum Foundation Wallet contract at 0x273930d2.

This contract is a proxy that delegates all calls to 0x273930d21e01ee25e4c219b63259d214872220a2(Wallet). See the master contract for the full logic.

Description

A 49-byte proxy stub deployed by the Ethereum Wallet (Mist) factory contract. When a user created a new wallet through the Mist UI, the factory generated this bytecode with the master Wallet address hardcoded at 0x273930d21e01ee25e4c219b63259d214872220a2.

The proxy copies incoming calldata to memory, then uses CALLCODE to execute the master wallet logic in the context of this contract storage. This means each wallet instance has its own storage (owners, daily limits, balances) but shares the master wallet code.

This was the only delegation mechanism available before EIP-7 introduced DELEGATECALL in the Homestead fork (March 2016). CALLCODE differs from DELEGATECALL in that msg.sender inside the called code refers to the proxy address, not the original caller.

With 1,989 identical deployments, this is one of the most widely deployed bytecodes in early Ethereum history.
