Blockchain that ships
— and stays
secure forever

Genuinely - most of the time, a well-designed database is faster, cheaper, and easier to maintain. Blockchain makes sense when you need trustless settlement between parties who don't trust each other, immutable audit trails that no single party can alter, or programmable rules that execute automatically without an intermediary. If your answer is 'we want the transparency', we'll give you an honest assessment of whether on-chain or off-chain indexing makes more sense for your use case.

For a mid-size codebase (3,000–8,000 lines of Solidity), a thorough audit takes 2–4 weeks. Complex DeFi protocols with multiple interacting contracts take 4–6 weeks. Rushing an audit is how you miss things - we don't offer 48-hour audits, and you should be suspicious of firms that do.

It depends on your transaction volume, cost tolerance, regulatory environment, and whether you need composability with existing DeFi protocols. Ethereum for anything that benefits from the ecosystem. Solana for high-frequency, low-cost applications. Hyperledger for regulated industries that need permissioned access. We'll walk through the tradeoffs in the first call and give you a recommendation with reasoning.

Only if they were designed to be upgradeable from the start, using proxy patterns or similar mechanisms. Immutability is one of the properties that makes on-chain contracts trustworthy - adding upgradeability trades some of that trust for operational flexibility. We discuss this tradeoff explicitly in the architecture phase and design upgrade paths where they're appropriate, with timelocks and governance controls to prevent unilateral changes.

The audit is not the end of the engagement - it's a checkpoint. If we find critical issues, we fix them, re-test, and submit for re-review before anything goes near mainnet. The audit report documents everything found and resolved. We don't ship contracts with unresolved criticals, and we don't let clients override that call.

Gas efficiency is designed in, not bolted on at the end. We write contracts with storage layout, calldata encoding, and execution paths in mind from the first draft. After development, we run gas profiling with Foundry's gas snapshots and benchmark against baseline implementations. Typical projects come in 25–40% below naively-written equivalents.
