Hi everyone,<p>I made TimeBank <a href="https://timebank.tech" rel="nofollow">https://timebank.tech</a> , a Fullstack Decentralized Application that lets anyone lock away Ether or ERC20-standard compatible tokens (like those you seen in ICOs)for arbitrary periods of time.<p>Its backend is entirely on the Ethereum blockchain, 95% of the dev work was the UI and writing the smart contracts.<p>It doesn't handle any private keys directly, but relies on Injected Web3 (such as via the Metamask Chrome extension) or a local Ethereum node running on localhost:8545, and composes the transactions for the user to sign and broadcast.
Nice, but I think you should post the link directly.<p>Contract source, apparently: <a href="https://etherscan.io/address/0x459f90b6e8dc23bbf1ff4c2f22aa2149b4bd4cff#code" rel="nofollow">https://etherscan.io/address/0x459f90b6e8dc23bbf1ff4c2f22aa2...</a>
