What is CoinFabrik?
CoinFabrik is a blockchain development and security firm headquartered in Buenos Aires, Argentina, doing smart contract audits since 2014. It builds dApps and blockchain systems and states 60+ employees, 350+ security audits and 500+ projects, with regional offices in Brazil, the USA, Spain and Italy.
How CoinFabrik works
A CoinFabrik audit follows four steps.
You submit audit-ready code through the request form and get a quote and timeline. The team audits the code and shares a preliminary report privately. Your developers fix the findings. CoinFabrik then validates the fixes, updates the report and publishes it if you agree; it recommends making reports public. Auditors work in Solidity, Rust, Clarity, Go and Soroban, and past reports are listed on the site.
CoinFabrik also builds open-source analysis tools. Scout is a static analyzer for Soroban, ink! and Substrate code that runs as a CLI, a VS Code extension or a GitHub Action. Stacy analyzes Clarity contracts on Stacks, CyScout is a QL-based Solidity static analyzer, and SOLbricks is a Solana contract testing tool. The company says it is part of the Stellar Audit Bank, audits for the Polkadot Assurance Legion and Stacks, and runs a Stellar validator.
How to start with CoinFabrik
- For an audit, fill in the request form with your company email, repository link, deadline and technology: Solidity, Teal, Clarity, Rust or other.
- For development, advisory or due diligence work, use the contact form instead.
- The audit length depends on the code's complexity, libraries, oracles and dependencies, so share the repository early.
- The team is led by co-founder and CEO Sebastián Wain, with co-founder Sergio Lerner as advisor.
CoinFabrik fees and limits
- To secure a slot in the queue, CoinFabrik asks for 50% upfront and 50% when it delivers the final audit, with a statement of work and invoice first.
Audit prices are quoted per project from the length and complexity of the contracts, after the team reviews your repository. Payment goes to a USDT address it sends you, so plan for a stablecoin payment rather than a card or wire.
Risks to know before using CoinFabrik
- A CoinFabrik audit reviews the audit-ready code you submit, and publication is your choice.
- The preliminary report is shared privately, and CoinFabrik only "strongly" recommends publishing the final report it issues after validating your fixes.
- So when a project cites a CoinFabrik audit, check that a final report is public and that it matches the deployed code.
- Scout, its open-source bug detector, supports only Substrate, ink! and Soroban code, and the Scout page treats manual audits as the main safeguard.
- The website's own terms, dated January 1, 2022, provide the service as is, cap liability at the amount paid or $100 and apply Argentine law.
