Contract 0x9e15f66b34ed...139c931223f0
UnknownA time-locked escrow contract from August 11, 2015, funded with 20 ETH and featured on ether.camp as a notable early Frontier deployment.
Historical Significance
Featured by ether.camp founder Roman Mandeleil as one of the first notable contracts on Ethereum. The 20 ETH creation funding demonstrates early confidence in deploying real value to smart contracts during Ethereum's first two weeks. Its selection alongside the Ethereum Foundation treasury as a showcase for VM tracing places it among the earliest contracts deemed interesting by the developer community.
Context
Deployed during Ethereum's Frontier era, just 12 days after launch. This was a period of intense experimentation — developers were testing whether smart contracts could safely hold and manage ETH. The 20 ETH funding represents a meaningful financial commitment at a time when the total Ethereum ecosystem was nascent and tools like ether.camp were just launching.
Key Facts
Description
This contract was deployed on August 11, 2015 (block 69,444), 12 days after Ethereum mainnet launch. It was funded with 20 ETH in its creation transaction — a significant amount for the era — suggesting it served as a functional time-locked escrow or deposit contract rather than a mere test.
The contract received 10 transactions from 2 unique addresses. After the initial 20 ETH deposit, a second address sent 0.5 ETH to the contract, indicating at least one external user interacted with it. The deployer (0xcD063B3081Ea55535E5b60a21eff7f14E785A877) made several subsequent function calls, including one on August 17 — a week after deployment — suggesting ongoing management.
This contract was featured by Roman Mandeleil (founder of ether.camp) in an August 12, 2015 Reddit post announcing the ether.camp block explorer's VM trace feature. Mandeleil highlighted it alongside the SciFi voting contract (0xd94badbec), a pricing contract (0xdf373f3d), and the Ethereum Foundation treasury as contracts worth exploring with the new tracing tool.
No source code has been verified on Etherscan. Approximately 0.01 ETH remains in the contract.
