Blockchain Engineering Services

Every layer of the blockchain stack — from contract design through dApp frontend, with formal security guarantees throughout.

Smart Contract Development

Production-ready Solidity 0.8.x, Rust (Move/Anchor), and Vyper contracts with 100% test coverage, property-based testing (Echidna), invariant analysis, and OpenZeppelin pattern integration for battle-tested security.

Formal Verification & Audits

Line-by-line security audits with Slither/Mythril SAST, formal verification via Certora Prover (mathematically-proven contract correctness), invariant checking, fuzz testing, and multi-stage attestation reports.

Contract Development Lifecycle

Specification before code. Formal verification before deployment. This is how you achieve zero security incidents at scale.

01

Protocol Design & Threat Modeling

Define protocol invariants, trust assumptions, and economic constraints. STRIDE threat analysis for on-chain components. Formal specification before a line of code is written.

02

Architecture & Standards Selection

Choose ERC standards (ERC-20, ERC-721, ERC-1155, ERC-4626), proxy patterns (UUPS, Transparent), upgrade strategy, and access control model. Multi-sig deployment planning.

03

Contract Development & Testing

TDD approach with Foundry/Hardhat. Unit tests, integration tests, fork tests against mainnet state. Property-based testing with Echidna. Gas benchmarking and optimization.

04

Internal Review & Optimization

Internal code review by senior solidity engineer not involved in development. Gas optimization pass (storage layout, inline assembly where safe). Natspec documentation generation.

05

Formal Verification & Audit

Certora Prover for critical invariants. Third-party audit if TVL > $1M. All findings triaged, fixed, and retested. Audit report published for community transparency if desired.

06

Deployment & Monitoring

Multi-sig deployment ceremony (Gnosis Safe). Verified contract source on Etherscan/block explorer. Tenderly monitoring with automated alerts for unusual transactions. Incident response plan.

Decentralized Lending Protocol

DeFi Protocol — Ethereum + Arbitrum + Optimism

DeFi

Challenge

Design and build a collateralized lending protocol from scratch. Support 8 collateral types including LSDs (stETH, rETH). Need formal verification of liquidation logic (the most critical economic invariant). Deploying on 3 chains simultaneously with synchronized liquidity. Must pass independent audit before mainnet launch with $50M seed TVL.

Technical Approach

14-week build using Foundry with 1,400+ tests and 100% coverage. UUPS proxy with 72-hour timelock. Certora formal verification for all liquidation invariants (12 properties proven). LayerZero for cross-chain state sync. Chainlink price feeds with circuit breakers. Gnosis Safe (4-of-6) for admin. Full Tenderly monitoring suite.

Outcomes

$180M TVL within 3 months of launch
0 security incidents in 18 months
12 Certora invariants formally proven
Independent audit: 0 Critical, 0 High findings
35% gas reduction vs initial implementation
