NFTDevelopment &Engineering

Contract development is our core practice - but we don't operate in isolation from your creative team. We integrate directly with your art director, generative artists, or brand agency to handle trait composition, rarity weighting, metadata schema design and reveal mechanics. We don't replace your creative direction; we engineer the on-chain infrastructure that makes it work - including provable rarity via Chainlink VRF, IPFS or Arweave metadata pinning and marketplace-compatible JSON schemas. If you don't have a creative team yet, we can recommend partners we've worked with on prior collections; if you do, we slot into your existing workflow without forcing tooling changes. The deliverable from our side is always: contracts that mint exactly the assets your brand approved, with metadata that resolves correctly across every marketplace your collection will list on.

ERC-721, ERC-1155, ERC-2981, ERC-4907, ERC-6551, ERC-721A, Metaplex on Solana and custom extensions where marketplace requirements allow. We deploy across Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche subnets and Solana - chain selection follows your audience, gas strategy and marketplace roadmap.

We implement EIP-2981 with documented basis points, operator-filter registries where your royalty policy requires them and on-chain payout routing for multi-creator splits. Compatibility matrices for OpenSea, Blur, Magic Eden and major aggregators are delivered with your launch pack.

Yes - listing, offer, auction and settlement contracts; indexer-backed APIs; and brand-facing front ends. Fee logic, creator verification hooks and moderation workflows are scoped to your compliance and brand-safety requirements.

We recommend storage strategy against your permanence, cost and mutability requirements: fully on-chain for small payloads, IPFS with pinning SLAs for most PFP collections, Arweave for permanence-critical references - with gateway fallbacks and integrity checks documented before mint.

Yes - companion contracts across EVM L2s, Solana counterparts and bridge messaging (e.g. LayerZero, Wormhole) with supply and ownership reconciliation so marketplaces and explorers show consistent collection state.

Allowlist signatures with expiry and nonce discipline, per-wallet caps, phased windows, optional gas refunds and mempool-aware testing against sniper scripts. Mechanics are fuzzed under adversarial conditions before mainnet.

We ship the audit preparation pack, coordinate with your firm or our network, triage every finding, implement root-cause fixes and add regression tests through sign-off - with emphasis on mint paths and royalty logic.

A collection-plus-marketplace programme from Discovery through audit-ready deploy often runs 10-18 weeks depending on generative complexity, chain count and audit availability. Typical team: lead NFT engineer, security-focused reviewer and DevOps for pinning and deploy pipelines - scaled per scope.

Useful inputs: collection size and mint mechanics, target chains, marketplace listing plan, royalty recipients and splits, creative pipeline (generative vs curated), IP licensing constraints and target mint date. We respond within one business day with a scoped recommendation.
