VanityMarket allows you to buy and sell custom Ethereum addresses (e.g., starting with 0xdead...) in a trustless, decentralized manner using Elliptic Curve Cryptography.
For Buyers: You provide a Public Key. The private key never leaves your device. Sellers find a "private key offset" that modifies your key to generate the desired address.
For Sellers: Use GPU tools to find the offset, submit it to the contract, and get paid instantly upon verification.
