Blockchain & Web3

On-chain engineering, without the hype.

We treat a blockchain as what it is: a very reliable, very public database with money attached. Most of the real work is the off-chain infrastructure around it — and that is the part we have been building for years.

What we deliver

  • →Smart contracts in Solidity on EVM chains — tokens, escrow, vesting, access control. Testnet-first and fully covered by tests.
  • →On-chain data and indexing: transfer and swap pipelines, wallet clustering, liquidity and price feeds.
  • →Wallet connect flows, signature-based auth, and stablecoin settlement.
  • →Event-driven trading and agent infrastructure with risk limits and a paper mode before a cent moves.
  • →Keys stay server-side. Every third-party call is made by the backend.

Frequently asked questions

Which chains do you build on?

Ethereum, Base, Arbitrum, and other EVM chains — the same codebase, a different RPC.

How do you approach smart contract security?

Audited patterns rather than clever ones, testnet-first delivery, full test coverage, and keys kept server-side.

How do engagements work?

Either a written scope with a fixed quote for a defined project, or senior engineers embedded in your team for ongoing work. You know what you are paying for before anything starts.
