Technical & Commercial FAQs
Gasless NFT Minting: Key Questions
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a gasless minting solution.
We implement a meta-transaction relayer architecture. Your users sign minting requests off-chain, which our secure, high-availability relayers submit and pay for on-chain. You pre-fund the relayer with native tokens or use our managed credit system. This abstracts gas complexity entirely from the end-user, providing a seamless Web2-like experience while maintaining full on-chain finality and security.
