CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Full Lifecycle Development: From initial design and
Hardhat/Foundrytesting to mainnet deployment and verification. - Security-First: Every contract undergoes internal audits and formal verification before we recommend third-party review.
- Protocol Integration: Native support for
ERC-20,ERC-721,ERC-1155, and custom cross-chain standards.
Deliver a secure, auditable foundation for your token, DeFi protocol, or NFT project in as little as 3 weeks.

COMPREHENSIVE SECURITY REVIEW
What Our Fraud Proof Audit Covers
Our audit delivers a rigorous, line-by-line analysis of your Optimistic Rollup bridge's fraud proof mechanism. We identify vulnerabilities that could lead to fund loss or network liveness failures, providing you with actionable remediation and the confidence to launch.
01
State Transition Logic
In-depth review of the core state transition function to ensure only valid state roots can be finalized. We verify the logic for processing deposits, withdrawals, and cross-chain messages is mathematically sound and free from edge-case failures.
02
Fraud Proof Verification
Analysis of the fraud proof verification game, including the challenge period, bisection protocol, and one-step proof execution. We test for logic flaws that could allow invalid state roots to be confirmed or prevent honest challenges from succeeding.
03
Bonding & Slashing Mechanisms
Security assessment of the economic incentives for validators and challengers. We verify that slashing conditions are correctly enforced and that bond sizes are sufficient to disincentivize malicious behavior without being prohibitive.
04
Data Availability & L1 Interaction
Review of how transaction data is posted to and retrieved from the L1. We audit the logic ensuring data availability for fraud proofs and identify risks related to L1 reorgs, gas limits, and calldata pricing.
05
Upgradeability & Admin Controls
Security review of any proxy patterns or upgrade mechanisms. We map admin privileges, identify centralization risks, and ensure there are sufficient timelocks and multisig requirements to prevent unilateral malicious upgrades.
06
Gas Optimization & Edge Cases
Analysis of gas consumption in critical fraud proof paths to prevent out-of-gas failures during challenges. We systematically test for edge cases in withdrawal finality, failed messages, and network congestion scenarios.

SECURITY FIRST
Why a Specialized Fraud Proof Audit is Critical
Optimistic rollup bridges are only as secure as their fraud proof mechanism. A generic smart contract audit is insufficient to validate the complex, time-bound logic that protects billions in cross-chain assets. Our specialized audit targets the unique failure modes of optimistic systems.
03
Bonding & Slashing Mechanism Security
Analysis of the economic incentives for validators and provers. Ensures the slashing logic is tamper-proof and economically sound, disincentivizing malicious behavior without risking false penalties.
04
Worst-Case Gas Optimization
Stress-tests fraud proof execution under maximum L1 congestion. We optimize critical paths to guarantee proofs submit under the block gas limit, preventing denial-of-service attacks.
05
Adversarial Testnet Deployment
We deploy your bridge contracts to a private testnet and execute coordinated attack simulations. This uncovers race conditions and edge cases that static analysis misses.
