Centralized exchanges, smart contracts and dApps, stablecoin payment rails, wallets and custody, and token economies for real-world-asset platforms.

It depends on scope. For reference, we delivered a centralized exchange in 20 weeks and stablecoin payment rails in 5. We agree milestones up front.
How do you handle security?
Contracts go through a full audit before launch and every finding is worked through before deployment. Our most recent audit launched with zero critical findings.
Which chains do you work with?
We choose per use case after comparing chains, custody and infrastructure options. Our smart contract work has shipped across multiple chains.
Do you handle compliance?
We build KYC/AML into onboarding and design token economies with regulation in mind. Legal sign-off stays with your counsel.
How do you pick a Web3 development company?
Check for audited contract work, clear key management and compliance planning from the start. As a Web3 development company, and a blockchain development company, we follow the ethereum.org guide to smart contracts for contract basics and test before every release.
