NFT Smart Contracts
NFT contracts are deceptively complex — mint mechanics, metadata, royalties, reveal phases, and marketplace compatibility all require careful implementation. We build NFT contracts that are secure, gas-efficient, and fully featured.
// Key benefits
What makes this service valuable
Gas-efficient minting
ERC721A for batch minting efficiency, optimised storage layout, and merkle-based allowlists — reducing gas costs for both deployment and user minting.
Marketplace compatible
OpenSea, Blur, and LooksRare compatibility with EIP-2981 on-chain royalties, Operator Filter Registry support, and metadata standards that render correctly on all major platforms.
Reveal mechanics
Blind reveal with Chainlink VRF for provably fair randomness, pre-reveal placeholder, and metadata reveal mechanics that build launch anticipation.

NFT contracts built for launch and beyond
NFT launches are high-stress events: simultaneous minting, gas spikes, and security attacks from bots and front-runners. We build contracts that handle launch conditions gracefully — batch minting, allowlist phases, and price escalation mechanics.
Post-launch NFT contracts need ongoing consideration: royalty enforcement, metadata updates, staking and utility extensions. We architect for this lifecycle from the start.

// FAQ
Common questions about nft smart contracts
What is the difference between ERC-721 and ERC-721A?+
ERC-721A (by Azuki) is a gas-optimised extension that reduces the cost of batch minting significantly — minting 10 NFTs costs approximately the same as minting 1 with ERC-721A vs 10x the cost with standard ERC-721.
Do you store NFT images on-chain or off-chain?+
Storing images fully on-chain is gas-prohibitive for most projects. We use IPFS or Arweave for decentralised storage, with CID references stored on-chain. Arweave provides permanent storage; IPFS requires pinning.
