Critical Audit Findings
From a single token contract to a full multi-chain protocol — shipped to mainnet, not just to a demo.
End-to-end decentralized products, from protocol design to production launch.
Solidity and Rust contracts written to standards, tested line by line.
dApp frontends that make on-chain interactions feel like normal software.
MetaMask, WalletConnect, Phantom and embedded wallets — non-custodial by default.
ERC-20, ERC-721 and ERC-1155 tokens with vesting, staking and governance.
Minting, marketplaces and royalties that hold up under launch-day load.
On-chain voting, treasury management and governance that members trust.
Connect on-chain logic to the apps, payments and back-office systems you already run.
Proven libraries and tooling — because unaudited novelty is expensive here.
On-chain code is public, permanent, and holds real value. We build like it.
Built on battle-tested OpenZeppelin standards and reviewed line by line before anything touches mainnet.
Storage layout, batching and pattern choices that routinely cut transaction costs 30–60%.
Full test coverage, fuzzing and documentation your external auditors won't fight you over.
Ethereum, Polygon, Arbitrum, Base, BNB Chain and Solana — deployed where your users already are.
Your users keep control of their own keys and assets. We architect for that from day one.
Source-verified contracts and public explorer links, so anyone can check the code behind your product.
A deliberate path from whiteboard to mainnet, with the audit built into the middle of it.
Architect
Protocol design, token model and chain selection mapped to your goals and budget.
Build
Contracts and dApp written to standards, with tests authored alongside every function.
Audit & Harden
Internal review, static analysis, fuzzing, and coordination with third-party auditors.
Deploy & Monitor
Testnet, then mainnet launch with monitoring, alerting and clear upgrade paths.
On-chain products we've shipped, and what they measured after launch.

Every engagement is scoped to your protocol — these are starting points, not surprises.
A single contract suite, built right and shipped safely.
Contracts plus the Web3 product your users actually touch.
Multi-chain protocols, governance and long-term operations.
Third-party audit fees are billed at cost by the audit firm and quoted separately.
“Our contracts came back from an external audit with zero critical findings. That is not the norm, and it saved us a funding round of delays.”
Tomas Lindqvist
CTO, VaultChain
“They cut our mint cost by half and the marketplace held up on launch day without a single failed transaction.”
Amara Diallo
Co-founder, Artefact
“ITLab24 connected on-chain traceability to our existing ERP without forcing us to rebuild it. That pragmatism is rare in Web3.”
Henrik Vogel
VP Operations, SupplyLedger
Ethereum and EVM chains (Polygon, Arbitrum, Base, BNB Chain) plus Solana. We recommend a chain based on cost, speed, and where your users already are — not on hype.
We write audit-ready code with full test coverage and coordinate third-party audits for you. We also run internal review, static analysis and fuzzing before anything reaches mainnet.
A great deal at scale. Storage layout, batching and pattern choices routinely cut deployment and per-transaction costs by 30–60% — which compounds across every user you onboard.
Yes. Most of our Web3 work connects to systems clients already run — payments, ERPs, customer apps — rather than replacing them.
We support token design and governance modeling, and we work alongside your legal counsel. We're engineers, not lawyers — we don't provide legal or financial advice.
We monitor contracts and infrastructure, maintain upgrade paths where your architecture allows them, and offer ongoing support retainers.
Let's pressure-test the idea and scope it before a line of Solidity gets written.
