PROVEN PROCESS
Our Bitcoin L2 Security Audit Methodology
Our systematic, multi-layered audit approach is designed to identify critical vulnerabilities and architectural flaws before they reach mainnet, ensuring your protocol's integrity and user funds are protected.
03
Manual Code Review & Exploit Simulation
Our senior auditors conduct line-by-line manual review and simulate complex, multi-step exploit scenarios that automated tools cannot detect.
04
Economic & Incentive Analysis
We stress-test your protocol's economic model, validator incentives, and slashing conditions to ensure long-term security and resistance to malicious actors.
06
Remediation & Final Verification
We provide prioritized, actionable remediation guidance and conduct a final verification audit to confirm all critical issues are resolved before launch.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process includes formal verification and comprehensive audits to ensure security and reliability from day one.
- Token Systems:
ERC-20,ERC-721,SPLtokens with custom minting, vesting, and governance. - DeFi Protocols: Automated market makers, lending pools, and yield strategies with gas optimization.
- Enterprise Logic: Multi-signature wallets, access control, and compliance-ready modules (e.g.,
ERC-3643).
We deliver audit-ready code in 2-4 weeks, backed by a 99.9% uptime SLA for deployed contracts. Our contracts are built with
OpenZeppelinstandards and include full documentation and upgrade pathways.

Bitcoin L2 Security Audit FAQs
Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a Bitcoin L2 security audit partner.
We employ a multi-layered methodology tailored for Bitcoin's unique architecture. This includes: 1) Architecture Review of the L2's consensus mechanism, bridge design, and fraud proofs. 2) Smart Contract Audit of core logic (e.g., rollup contracts, state transitions) using both automated tools and 100% manual review. 3) Cryptographic Review of signature schemes, zero-knowledge proofs (if applicable), and key management. 4) Economic Security Analysis of slashing conditions, staking incentives, and governance. Our process is based on standards from OpenZeppelin and the NIST Cybersecurity Framework.
