NFT Minting Smart Contracts
Gas-optimized ERC-721A and ERC-1155 minting contracts with configurable supply, pricing, allowlists, batch minting, and reveal mechanics. Audited, tested, and deployable to any EVM chain.
We build gas-optimized NFT minting contracts, custom marketplaces, and royalty systems from strategy through launch — 500K+ NFTs minted across 30+ platforms we've shipped.

Gas-optimized ERC-721A and ERC-1155 minting contracts with configurable supply, pricing, allowlists, batch minting, and reveal mechanics. Audited, tested, and deployable to any EVM chain.
Full NFT marketplace builds — fixed price, auction, and offer listing mechanisms, royalty enforcement, collection pages, activity feeds, and wallet-gated access. Custom or integrated with OpenSea and Blur APIs.
On-chain royalty implementation using the ERC-2981 standard, compatible with major marketplaces. We also implement custom royalty enforcement mechanisms and royalty splitting for collaborative collections.
Decentralized metadata and asset storage using IPFS (via Pinata or NFT.Storage) and permanent Arweave storage. We handle batch uploads, metadata generation pipelines, and IPFS pinning strategies.
Merkle tree-based allowlist verification for gas-efficient presale access control. Multi-stage reveals with randomized token assignment using Chainlink VRF for provably fair distribution.
Real-time collection analytics — floor price tracking, volume, holder distribution, rarity rankings, and wash trading detection. Integrated with OpenSea, Blur, and on-chain event indexing.

Fixed milestones, working software every fortnight, and no surprises on the invoice.
We define your collection architecture — token standard, supply, pricing tiers, allowlist strategy, reveal mechanics, and royalty structure — aligned with your community and revenue goals.
Gas-optimized minting contracts built with ERC-721A for significant gas savings on batch mints, thorough test coverage, allowlist verification via Merkle proofs, and Chainlink VRF integration for reveals.
Frontend marketplace development with wallet connection, collection browsing, listing/buying/bidding flows, royalty display, and activity feeds. Responsive design optimized for both desktop and mobile users.
Full launch support including metadata pipeline deployment to IPFS/Arweave, contract verification on Etherscan, allowlist management tools, and a war room during mint day for rapid issue resolution.
How we price, who we staff and what happens after launch — the parts that decide whether a project actually lands.
You know the cost and the timeline before a line of code is written. No hourly billing, no scope-creep surprises.
Full source code, credentials and intellectual property transfer to you on final payment. We sign the IP assignment on day one.
Every project is staffed by engineers with years of production experience — no juniors learning on your budget.
Built for PIPEDA and provincial privacy law, with data kept on Canadian infrastructure where it matters.
A focused, fixed-price path from idea to a launched product, refined across dozens of startup engagements.
Tiered SLAs from monitoring and bug fixes to a dedicated team with 24/7 response. Most clients stay for years.
Independent awards and partner tiers, each one earned on delivered work.

Ask our teamERC-721 is the classic standard where each token is unique — ideal for PFP collections, 1-of-1 art, and collectibles where individual ownership history matters. ERC-1155 supports multiple token types in one contract and allows multiple editions of each token — better for gaming items, tickets, membership tiers, and collections where some tokens exist in quantities greater than 1. ERC-721A (by Azuki) is a gas-optimized variant of ERC-721 that dramatically reduces minting costs for large batches and is our default recommendation for PFP collections.
Never store NFT assets or metadata on centralized servers — if your server goes down, your NFTs lose their images permanently. We recommend a two-tier approach: IPFS for metadata (via Pinata with multiple pinning nodes) for cost-effective decentralized storage, and Arweave for assets you want guaranteed permanent storage (one-time upload fee, data stored forever). We automate the entire upload and metadata generation pipeline for your collection.
ERC-2981 is the standard for on-chain royalty information that tells marketplaces what royalty percentage to pay. However, major marketplaces (OpenSea, Blur) have made royalties optional for buyers, making enforcement difficult at the protocol level. Solutions include: building your own marketplace with enforced royalties, using operator filter registries to block sales on zero-royalty marketplaces, or accepting optional royalties and building community value in other ways. We help you navigate the trade-offs and implement the approach that fits your project.
Several proven techniques reduce minting gas costs: ERC-721A stores ownership data for batch mints far more efficiently than standard ERC-721, saving 60–80% on gas for multi-mint transactions. Merkle tree allowlists use a single bytes32 root on-chain instead of storing thousands of addresses. Lazy minting defers token creation to transfer time. We benchmark gas costs during development and optimize aggressively before deployment.
Fair reveals require provable randomness — without it, savvy minters can game the system by predicting which token IDs map to rare traits. We implement reveals using Chainlink VRF (Verifiable Random Function), which provides cryptographically provable on-chain randomness that neither we nor you can manipulate. The reveal process: tokens mint with placeholder metadata, a random seed is requested from Chainlink VRF, the seed determines the offset for final token assignments, and metadata is revealed across the entire collection simultaneously.
