Blockchain & Web3

On-chain work is ordinary engineering with an unusual failure mode: a deployed contract cannot be patched, and a lost key cannot be reset.

Wallet integration, token and NFT contracts, on-chain data indexing, and bridging chain state into ordinary business systems.

What we do

Blockchain & Web3

We handle wallet integration, token and NFT contracts, and the indexing layer that turns chain events into data an ordinary application can query without hitting a node on every page load.

Contracts are written to be reviewable: scoped, documented, tested against the failure cases, and deployed to a testnet with the exact same script that will run on mainnet. Upgrade and ownership decisions are agreed with you before deployment, not assumed.

The part most projects underestimate is the bridge back to normal systems: reconciling on-chain state with your own database, and handling the window where a transaction is submitted but not yet final. We build that explicitly.

Blockchain & Web3

What you get

  • Wallet connection and signing flows with clear states for pending and failed

  • Token or NFT contracts, tested and deployed through a repeatable script

  • An event indexer so your application queries a database, not a node

  • Reconciliation between on-chain state and your own records

  • Key custody and upgrade decisions documented and agreed before deployment

Our Expertise

Typical stack

  • Node.js: APIs, jobs and integration workers
  • Next.js: web applications and marketing sites
  • React: operator dashboards and internal tools
  • Docker: containerised builds and deployments
