Coffee’sCustomContracts.
Efficient, Secure, Bespoke NFT smart contracts & apps
Hello! My name is Aaron Hanson (AKA “Coffee Converter”). I’ve been writing software for over 30 years. By day, I’m the Staff Solidity Engineer at Nifty Gateway. When not employed full-time, I’ve developed and deployed several DeFi and NFT smart contracts and related apps.My contracts are customized and optimized for your exact needs. They are highly gas-efficient, clearly documented, unit tested with 100% coverage, and fully-featured for token holders and contract admins. I can also provide many related services (web apps, hosting, IPFS gateways, etc).
