Web3 & Blockchain

High-Performance NFT Infrastructure Built for Real Utility and Community.

We build generative art engines, gas-optimised minting smart contracts, decentralised IPFS storage pipelines, and custom marketplace experiences.

What we build

NFT Development, end to end.

01

Gas-Optimised Minting Contracts (ERC-721A)

Smart contracts allowing users to mint multiple NFTs in a single transaction for virtually the same gas fee as minting one.

  • ERC-721A batch minting algorithms
  • Merkle tree cryptographic allowlists
  • Anti-bot mint cooldown guards
  • EIP-2981 royalty enforcement
02

Dynamic & On-Chain Metadata Systems

NFTs whose artwork and traits evolve over time based on real-world events, gaming achievements, or smart contract interactions.

  • SVG generation directly in Solidity
  • Chainlink VRF random trait assignment
  • Decentralised IPFS & Arweave pinning
  • Trait reveal mechanics
03

Custom NFT Marketplaces & Launchpads

Bespoke storefronts allowing brands to sell, auction, and trade their collections without third-party marketplace fees.

  • Dutch & English auction contracts
  • Credit card to NFT fiat on-ramps
  • Secondary trading escrow
  • Custom trait filtering search

Problems we solve

Common friction, addressed directly.

  • The problem

    Users paying hundreds of dollars in gas fees just to mint a single NFT during peak launches.

    Our approach

    We implement the ERC-721A standard, significantly reducing gas costs for batch mints.

  • The problem

    Centralised metadata servers disappearing, leaving buyers with broken images and lost artwork.

    Our approach

    We store all images and metadata permanently on decentralised IPFS or Arweave with immutable hashes.

  • The problem

    Bots draining mint allocations before real community members have a chance to participate.

    Our approach

    We implement cryptographic Merkle proof allowlists and CAPTCHA-backed signature minting verification.

Capabilities

Standards we work to.

  • ERC-721A & ERC-1155 Mastery

    Industry-standard contracts optimised for single collectibles, generative drops, and gaming editions.

  • Permanent Arweave & IPFS Storage

    Ensuring artwork assets remain permanently accessible with decentralised content addressing.

  • Credit Card Fiat On-Ramps

    Allowing mainstream non-crypto users to purchase NFTs using standard Apple Pay and credit cards.

  • EIP-2981 On-Chain Royalties

    Programmatic royalty distribution directing secondary sales proceeds to creator treasuries.

    Executing the public drop, automated metadata reveal, and OpenSea/Magic Eden indexing.

Representative scenarios

Where this service fits.

Illustrative examples of the kinds of problems this service addresses and how we would approach them. They are not client case studies.

Generative 10K PFP Collection Drop

Typical challenge

A digital brand planning a 10,000-piece collection needed low mint fees and allowlist tiers.

How we would approach it

An ERC-721A contract with Merkle allowlists and batch minting to keep fees low during launch demand.

VIP Membership Pass for Luxury Real Estate

Typical challenge

A real estate consortium needed dynamic NFTs providing physical access to private club lounges.

How we would approach it

An ERC-721 contract whose metadata reflects each member's verification status.

Security & performance

Considerations built in from the start.

  • Re-Entrancy & Mint Cap ProtectionsRigid per-wallet limits preventing single addresses from exhausting entire collection supplies.
  • Immutable Metadata LockingPermanent on-chain freezing functions ensuring creators cannot alter artwork post-launch.

FAQ

Questions we are often asked.

What is the ERC-721A standard and why do you use it?

ERC-721A is an optimised NFT standard created by the Azuki team. It allows users to mint multiple NFTs (e.g. 5 or 10 tokens) in a single transaction for almost the same gas fee as minting just 1 token, saving your community significant fees.

Can people without crypto wallets buy our NFTs?

Yes! We integrate fiat on-ramp APIs like Crossmint and Stripe, enabling buyers to purchase using Apple Pay, Google Pay, or credit cards. The NFT is automatically delivered to an email-based custodial wallet or their own Web3 address.

Where are the images and metadata stored?

We store all images and metadata on decentralised networks like IPFS and Arweave. Files are content-addressed, so any alteration changes their address, and we pin them with reliable providers so they stay available.

Can we have an unrevealed placeholder image before the official reveal?

Yes. We configure a secure reveal mechanism where an initial placeholder image is shown until you choose to publish the true metadata URI on-chain.
