Smart Contract Development

Smart Contracts,
Audited and Production-Ready.

Solidity development for Ethereum and EVM chains: ERC-20 / ERC-721 / ERC-1155 tokens, escrow and milestone payments, DAOs, allowlist-gated security tokens, and cross-chain bridges — written to security-first patterns and shipped with full test coverage.

What you get when you work with us

Solidity contracts
ERC-20, ERC-721, ERC-1155, escrow, vesting, multisig, governance, and custom protocol contracts — written using OpenZeppelin patterns where appropriate, custom where the use case requires it.
Full test coverage
Foundry or Hardhat test suites covering unit tests, integration tests, fuzz tests, and invariant tests — not just the happy path. Static analysis with Slither and Mythril before any deployment.
Audit coordination
We do not self-audit production contracts. We prepare the codebase for an independent third-party audit (Trail of Bits, OpenZeppelin, ConsenSys Diligence, or comparable) and coordinate the remediation cycle.
Deploy + verify on-chain
Mainnet, L2 (Arbitrum, Base, Optimism, Polygon), or testnet deploys with Etherscan source verification, contract addresses documented, and a runbook your team can use for upgrades and emergency pause.

Common questions

How long does a smart contract development engagement take?

A focused contract suite (e.g. an ERC-20 with vesting + governance, or an escrow protocol) is typically 3–6 weeks of build + test, then 2–4 weeks for the audit and remediation cycle. A full DeFi protocol or complex tokenization project is 3–6 months end-to-end.

Do you handle the audit, or do we need to hire a separate firm?

Audits should always be independent — we will not audit our own code. We prepare the codebase to a high audit-readiness bar (NatSpec docs, invariant test suites, threat model write-up), help you select a reputable audit firm, and own the remediation cycle. The audit itself is contracted separately with the audit firm.

Which chains do you deploy to?

Ethereum mainnet, Arbitrum, Base, Optimism, Polygon, and other EVM-compatible L2s. We default to L2s for any use case with high transaction volume — gas costs on mainnet rarely make sense for production user flows in 2026. We will deploy to a private EVM chain if your compliance posture requires it.

What about post-deploy support?

Smart contracts are not fire-and-forget software. We offer post-deploy support retainers covering monitoring (transaction anomaly alerts), upgrade execution (for upgradeable proxies), and emergency response. Most production engagements include a 3-month post-deploy support period by default.
