I will build secure web3 dapps, smart contracts, and defi solutions
Over deze dienst
Looking for secure, gas-efficient, and production-ready smart contracts? You're in the right place!
I'm a full-stack blockchain developer specializing in Solidity (EVM) and Solana (Rust/Anchor). I build complete Web3 dApps, smart contracts, backend systems, and frontend interfaces.
I develop ERC-20, ERC-721, ERC-1155, SPL tokens, NFT marketplaces, staking, DeFi, AMMs, yield farming, DAOs, stablecoins, and RWA tokenization. I also handle cross-chain bridges and multi-chain integrations across Ethereum, Polygon, BNB Chain, Arbitrum, Base, Avalanche, and Solana.
On the frontend, I build React/Next.js dApps with wallet integration (MetaMask, WalletConnect, Phantom, RainbowKit).
All contracts are security-audited, gas-optimized, and tested with Hardhat/Foundry/Anchor for mainnet deployment.
What you get: clean source code, deployment support, and documentation.
Contact me before ordering to discuss requirements and get a custom quote.

Veelgestelde vragen
Q1: Do you build both EVM and Solana smart contracts?
Yes! I develop on both EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base, BNB Chain) using Solidity, and on Solana using Rust and the Anchor framework.
Q2: Are your smart contracts secure and audited?
All contracts are written with security best practices, thoroughly tested, and reviewed for common vulnerabilities such as reentrancy, overflow, and access control issues. I use Hardhat, Foundry, and Anchor for testing before deployment.
Q3: Can you build a complete dApp, not just the smart contract?
Absolutely. I deliver full-stack Web3 dApps, including the smart contract, backend integration, and a React/Next.js frontend with wallet support (MetaMask, WalletConnect, Phantom).
Q4: Do you handle deployment to mainnet?
Yes. I provide full deployment support, including testnet and mainnet deployment, contract verification on Etherscan/Solscan, and post-deployment documentation.
Q5: Do you sign NDAs or provide private/confidential work?
Yes, I'm open to signing NDAs and delivering fully private, confidential work. Your code and project details stay with you.
Q6: Why should I contact you before placing an order?
Every blockchain project is unique. A quick chat helps me understand your exact needs, avoid scope mismatches, and give you an accurate timeline and price — saving us both time.
