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. By night, I write NFT (and other) smart contracts and related apps.My NFT 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).
