// Smart Contract Language
Solidity
EVM-compatible smart contract development with security focus.
25+ contracts deployed · 4+ years hands-on
// Overview
How we use Solidity
Solidity is our primary language for EVM smart contract development. We use Hardhat and Foundry for testing, OpenZeppelin for battle-tested base contracts, and Slither for static analysis, security is a first-class engineering concern, not an afterthought.
// Use cases
- ERC-20 and custom token contracts
- NFT contracts (ERC-721, ERC-1155)
- DeFi protocol logic
- DAO governance contracts
- Multi-sig and access control contracts
// Why it matters
OpenZeppelin foundations
Audited base contracts for tokens, access control, upgradeable proxies, and governance, reducing custom code surface area and attack vectors.
Foundry for testing
Foundry enables fuzz testing with Echidna-style property-based tests, fork testing against mainnet state, and fast Solidity-native test authoring.
Type safety with viem
viem + TypeScript ABI types provide fully typed contract interactions on the frontend, eliminating a class of integration errors.
// Production patterns
How we ship with Solidity
Hardhat + Foundry dual toolchain, Solidity tests in Foundry for fuzz properties, Hardhat for deployment scripts and mainnet fork tests.
Upgradeable contracts use TimelockController + transparent proxy patterns; admin keys on hardware wallet or Fireblocks policy engine.
Pre-audit checklist: Slither, Mythril, 90%+ branch coverage on value-transfer paths, and documented threat model for oracle and admin roles.
Custody-side patterns, Fireblocks vaults, MPC/TSS, HSM-backed keys, are detailed on our Fintech & Crypto page ›.
// Integrations
- Fireblocks custody API
- OpenZeppelin Defender
- Chainlink oracles
- The Graph indexers
- TRC20 / ERC-20 webhook reconciliation (off-chain)
// FAQ
Solidity: common questions
Which chains do you deploy to?+
Ethereum L1, Polygon, Arbitrum, and BSC most often, chain choice driven by fee profile and custody partner support.
Do you replace third-party audits?+
No. Internal review is preparation; Trail of Bits, ConsenSys Diligence, or OpenZeppelin audit required before significant TVL.
Can you integrate custodial wallets?+
Yes, Fireblocks and similar patterns for users who should not manage seed phrases; export path documented for regulatory cases.
