04 / FAQ
Questions about Blockchain & Web3.
Which chains do you build on?
Ethereum and EVM-compatible chains in Solidity, and Solana in Rust, with the indexers, APIs and front ends that make on-chain data usable.
How do you approach security?
Threat modelling before code, thorough test coverage, internal review before any external audit, and coordination with third-party auditors when a launch needs one.
Can you build the web app around the contracts?
Yes. Wallet connection, signing flows and on-chain data in a clean Next.js front end are part of most engagements.
What happens after mainnet deployment?
Verification, monitoring and an upgrade plan. We watch contract activity and front-end health after launch and hand over runbooks to your team.
Do you offer smart contract reviews for existing code?
Yes. We review existing contracts for common vulnerability classes and gas issues, and report findings with severity and suggested fixes.
