DAO tooling startup
- Challenge
- ERC-20 voting hooks lacked cap checks and timelock on admin pause.
- Simplileap solution
- OpenZeppelin patterns, Slither/Mythril, and audit documentation pack.
- Outcome
- External audit: zero critical findings post-fix.
// Build
Smart Contract Testing & Deployment
Testing is not a step before deployment, it is the foundation of safe on-chain deployment. We apply multiple layers of testing methodology to maximise confidence before any contract touches mainnet.
// Key benefits
What makes this service valuable
Multi-layer testing methodology
Unit tests, integration tests, fuzz testing with Foundry, invariant testing, and mainnet fork testing combine to give high confidence in contract correctness.
Deployment safety protocols
Staged deployment (testnet → staging fork → mainnet), multisig deployment ownership, timelock contracts, and post-deployment monitoring are standard for any value-bearing contract.
Audit-ready documentation
Testing documentation, natspec comments, and security review notes are structured to minimise audit time and cost.
// Details
Testing that earns deployment confidence
On-chain bugs are permanent. The testing bar for smart contracts must be higher than for any other software. We use Foundry for fuzzing and property-based testing, Hardhat for integration and gas testing, and mainnet fork testing to validate behaviour against real protocol state.
We target 100% branch coverage for critical business logic, use the Echidna fuzzer for invariant testing, and simulate economic attack scenarios where relevant.
// What this includes
- Unit testing with Hardhat/Foundry
- Fuzz testing with Foundry
- Invariant testing with Echidna
- Mainnet fork testing
- Gas profiling and optimisation
- Slither and Mythril static analysis
- Staged deployment (testnet → mainnet)
// Deliverables
What you receive

- 01Comprehensive test suite (Hardhat + Foundry)
- 02Fuzz and invariant test results
- 03Static analysis reports (Slither/Mythril)
- 04Gas usage profile
- 05Deployment scripts with safety checks
- 06Post-deployment monitoring setup
// In practice
How smart contract testing & deployment engagements run
We typically anchor the first sprint on multi-layer testing methodology. Testing is not a step before deployment, it is the foundation of safe on-chain deployment. We apply multiple layers of testing methodology to maximise confidence before any contract touches mainnet. On Residency Road engagements, discovery maps dependencies and success metrics before sprint one. Architecture choices, API contracts, and observability hooks are documented before the first production deploy.

// FAQ
Common questions about smart contract testing & deployment
Can testing replace a professional audit?+
No, testing and auditing are complementary. Testing validates that the code does what you intend. Auditing identifies whether what you intend has security vulnerabilities. Both are necessary for production contracts.
What is fuzz testing?+
Fuzz testing generates thousands of random inputs to your contract functions and checks for unexpected behaviour, reverts, or invariant violations. Foundry's built-in fuzzer is one of the most powerful available tools for Solidity.
