Hire Web3 Developers — Full-Stack EVM + Solana
WeiBlocks delivers senior Web3 engineers — smart contracts, DApps, DeFi, NFTs, tokenization. Full-stack across EVM (Solidity) and Solana (Rust). Staff aug or project delivery.
Quick Answer
WeiBlocks provides pre-vetted full-stack Web3 developers covering smart contracts (Solidity, Rust), DApp frontends (React/Next.js, wallet integrations), and Web3 infrastructure. Engineers have shipped production code on Ethereum, Solana, and major EVM L2s. Engagements: staff augmentation (3+ months), project delivery, or hybrid. Available within 2 weeks. We don't outsource to junior offshore — every engineer has shipped production Web3 code.
Pricing: Starting at $90/hr · $14K/mo FTE

Engagement Models
Staff Augmentation
Full-stack Web3 engineers embedded in your team. 3+ months minimum.
Project Delivery
Defined Web3 project (DApp, marketplace, protocol) scoped and shipped end-to-end.
Hybrid
Architecture + scoping by WeiBlocks, execution by embedded engineers. Best for complex multi-component projects.
Tech Stack
The tools and libraries our Web3 developers use day-to-day in production engagements.
WeiBlocks vs. Typical Hiring Channels
| WeiBlocks | Typical Alternative | |
|---|---|---|
| Full-stack coverage | Contracts + frontend + infra in one engineer | Specialized in one layer |
| Chain breadth | EVM (all) + Solana | Usually one chain |
| Wallet integration depth | MetaMask, Phantom, RainbowKit, WalletConnect, Account Abstraction | Single wallet type |
| Production focus | Audit-ready contracts + production frontends | Demos and POCs |
| Time to start | 2 weeks | 4–8 weeks |
| Engagement flexibility | Staff aug, project, or hybrid | One model only |

Frequently Asked Questions
What does 'full-stack Web3 developer' mean?
An engineer who can write smart contracts AND the user-facing DApp that interacts with them — Solidity/Rust on-chain plus React/Next.js + wagmi/wallet adapters off-chain. You don't need to hire two separate engineers.
Which Web3 frameworks do you use?
Frontend: Next.js 15+, React 19, wagmi v2 + viem (EVM), Solana Wallet Adapter (Solana), RainbowKit/ConnectKit. Smart contracts: Foundry primary, Hardhat for some legacy projects, Anchor for Solana.
Do your Web3 engineers know account abstraction (ERC-4337)?
Yes — bundler integrations, paymaster contracts, custom 4337 wallet logic, gasless UX patterns. Account abstraction is a growing area we've built production systems on.
Can you build cross-chain Web3 applications?
Yes — Wormhole, LayerZero, Axelar, deBridge, Allbridge. Cross-chain DApps spanning EVM + Solana are a common engagement type.
What's the cost of a Web3 engineer?
Staff aug: $90–$180/hr or $14K–$28K/month FTE depending on seniority. Project delivery: scoped per project. Full DApp builds typically $30K–$200K depending on chain count and feature complexity.
