Informazioni su questo servizio
Need a senior Web3 + AI developer to build an AI x Blockchain dApp that actually ships? I build production-grade dApps with smart contracts + agentic AI, ideal for founders who want AI agents that can read data, call tools, and execute on-chain actions.
What I can deliver:
- EVM / L2 dApps (Ethereum, Arbitrum, Base, Polygon), WalletConnect/MetaMask
- Solidity contracts: tokens/NFTs, token gating, registries, payments, DeFi modules
- Agent workflows: tool-calling, permissions/policies, observability, admin dashboard, run history + DB
- x402 paywalled APIs / metered usage, ERC8004 identity/delegation patterns (if needed)
- Clean repo, tests, deployment guide (testnet/mainnet-ready)
Optional: RAG + memory (pgvector/Pinecone), usage metering, basic security review & gas abstraction.
Stack: Solidity (Foundry/Hardhat), Next.js/React, Node.js/Python, Postgres, APIs.
Message me your idea + chain + timeline and Ill suggest a clear MVP scope, milestones, and architecture.

What costs are NOT included?
Cloud hosting, RPC providers, sequencers, data availability, and gas fees are paid by the buyer.
How technical do I need to be to work with you?
Not very. I translate requirements into technical decisions and explain tradeoffs clearly.
Will I get the full source code?
Yes. You receive the full repository, configs, and documentation.
How do I choose the right package?
Message me your use case. I’ll tell you honestly which package fits — or if you don’t need an integration at all.
