Typical project size: $10k–$100k

What you get

  • A practical architecture for your Web3 product
  • Reliable wallet and transaction experience
  • Traceable on-chain and off-chain state
  • A safer path from testnet to mainnet

The problems we solve

You have a crypto product idea but need a production-grade architecture, not a prototype.

Wallet flows, signatures, chain events, and backend state are hard to keep consistent.

You need smart contract integration with proper security, monitoring, and operational controls.

The product has to be usable for real customers, not only crypto-native users.

What's included

Delivered by senior engineers, end to end

Web3 architecture

Define what belongs on-chain, what stays off-chain, and how contracts, APIs, wallets, and data stores work together.

Wallet and transaction flows

Build clear wallet connection, signing, transaction tracking, retry, and status flows for web products.

Indexers and backend APIs

Listen to blockchain events, normalize them into reliable product state, and expose clean APIs for your app.

Security and launch readiness

Design access control, admin actions, monitoring, and audit preparation before mainnet launch.
