Description

This contract represents the genesis of Ethereum’s smart contract layer. While later contracts would introduce callable functions, tokens, and complex state, this deployment proved that Ethereum could host executable programs on-chain.

Its importance lies not in functionality, but in precedence: it was the first confirmed instance of a smart contract being created on Ethereum mainnet, establishing the foundation for all contract-based applications that followed.

On August 7, 2015, at block 46,402, Anthony Eufemio (known on Reddit as aedigix, Chief Technology Officer at Digix) submitted a contract creation transaction intended to deploy a minimal Solidity contract that stored an owner address. The deployment was publicly described at the time as an effort to create the first smart contract on Ethereum.

Due to extremely low gas limits at Ethereum’s launch, the transaction ran out of gas during contract creation, and no runtime bytecode was ultimately deployed. As a result, the address contains no contract code and the deployment did not result in a persistent smart contract on-chain.
