Contract 0xde0b295669a9...40f4cb697bae

This contract is the first Ethereum Foundation treasury wallet and one of the earliest examples of institutional fund management implemented directly on Ethereum. Its design reflects early best practices around shared control and spending limits, preceding later standardization of multi-signature wallets.

The address became a long-standing reference point for the community, shaping early conversations about governance, accountability, and the role of foundations in decentralized ecosystems.

This multisig contract at address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe is the primary smart contract wallet associated with the Ethereum Foundation, deployed at block 54,092 on August 8, 2015 — 9 days after the Ethereum genesis block. The contract was created by address 0x5abfec25f74cd88437631a7731906932776356f9 and implements a multisignature wallet requiring approval from multiple keyholders before funds can be transferred.

The address is labeled "EthDev" and "Ethereum Foundation" across multiple blockchain analytics platforms. It served as the main treasury for funding Ethereum protocol development, developer grants, research, and operations during the early years of the project.

The contract source code was not verified on Etherscan. However, the bytecode matches the custom multisig wallet pattern common in 2015, predating the Gnosis Safe and other standardized multisig implementations. The contract has no name() function and carries no official name in its code.
