Hire Smart Contract Developers Who Ship Audit-Ready Code

WeiBlocks delivers senior smart contract engineers — Solidity for EVM, Rust/Anchor for Solana. Audit-ready by default. Available within 2 weeks via staff augmentation, project delivery, or hybrid.

Quick Answer

WeiBlocks provides pre-vetted smart contract developers writing audit-ready, gas-efficient code in Solidity (Ethereum/EVM) and Rust/Anchor (Solana). Every engineer has shipped production contracts handling real value. Common engagement types: 1) staff augmentation for ongoing contract work (3+ months), 2) project delivery for defined contract suites with audit prep included, 3) audit remediation when you've received an audit report and need fixes. Available to start within 2 weeks.

Pricing: Starting at $100/hr · $16K/mo FTE

What Smart Contract Developers Do at WeiBlocks

Solidity (EVM)

Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche. Foundry + Hardhat workflows, OpenZeppelin libraries.

Rust + Anchor (Solana)

Native Solana program development with Anchor framework, including Token-2022 extensions.

Security & Audit Prep

Slither, Mythril, Echidna fuzz testing, Foundry invariant tests, Certora formal verification when justified.

Gas Optimization

Storage packing, calldata efficiency, custom errors, assembly when justified. Gas-conscious by default.

DeFi Contract Patterns

AMMs, lending markets, perps, lending pools, yield strategies, MEV-aware design.

Standards & Interfaces

ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-2535 (Diamond), ERC-4337 (Account Abstraction), SPL Token & Token-2022.

Engagement Models

Staff Augmentation

Smart contract engineers embedded in your team. 3+ month minimum. Useful when you have an ongoing protocol with new features and audits.

Project Delivery

Defined contract suite scoped, designed, built, tested, and audit-prepped. Fixed-scope or milestone billing.

Audit Remediation

You received audit findings — we fix them, re-test, and prep for re-audit. Shorter engagement, focused outcome.

FAQ

Frequently Asked Questions

Do your smart contract developers also coordinate audits?

Yes — we prep contracts for audit (tests, documentation, NatSpec) and coordinate with audit firms (OpenZeppelin, Trail of Bits, CertiK, Halborn, Ottersec for Solana) on your behalf. The audit fee goes to the audit firm directly.

What test coverage do you target?

100% line + branch coverage on critical paths, Foundry invariant tests for state machines, fuzz testing (Echidna or Foundry) for edge cases, and Certora formal verification when economic risk justifies it.

Can you audit smart contracts written by someone else?

We provide internal security reviews — not formal audits (those require accredited firms). Reviews typically take 1–2 weeks and catch 70–80% of what a paid audit will find. Useful as a pre-audit step or for in-house code.

What does smart contract work cost?

Staff aug: $100–$200/hr or $16K–$32K/month FTE. Project delivery: single contract + tests + audit prep $8K–$25K; multi-contract DeFi protocol $50K–$200K. Audit remediation typically $5K–$30K depending on finding count.

Do you have experience with ERC-4337 Account Abstraction?

Yes — bundler integrations, paymaster contracts, custom 4337 wallet logic, and recent EntryPoint v0.7 updates. Account abstraction is a growing area we've built production systems on.
