Over deze dienst
A smart contract cannot be patched after it goes live. A bug in production is not a support ticket, it is lost funds. I write, test and audit your contract so that does not happen, then deploy and verify it on mainnet.
WHAT I BUILD
Tokens: ERC20, BEP20, TRC20 and SPL (mint, burn, tax, reflection)
Presale, staking, vesting and reward contracts
NFT contracts: ERC721, ERC1155 and soulbound
DeFi: DEX, escrow, prediction markets and custom logic
Upgradeable contracts (UUPS and Transparent proxy)
Security audit of new or existing contracts, with a written report
CHAINS
Ethereum, BSC, Polygon, Base, Arbitrum, Tron and Solana.
HOW I WORK
Solidity on OpenZeppelin standards, tested with Hardhat or Foundry. Rust and Anchor on Solana. Every contract is checked for reentrancy, access control and overflow before deploy, and the source code is verified on the explorer.
LIVE WORK FROM OUR STUDIO
FeatherPay (crypto Visa card platform), ProPred (on-chain prediction markets with staking and oracle disputes) and HumanLayer (proof of humanity protocol, soulbound NFT on Base with zero-knowledge proofs).
Send me your idea or spec and I will confirm the chain, scope and exact quote.

Veelgestelde vragen
Which blockchains do you work on?
Ethereum, BSC, Polygon, Base, Arbitrum, Tron and Solana. Solidity for EVM chains and Tron, Rust with Anchor for Solana. Tell me your chain and I will confirm.
Do I own the source code?
Yes. You get the full source, the tests and the deployment scripts. The contract is verified on the block explorer so anyone can read it.
What does the security audit cover?
Reentrancy, access control, integer overflow, front-running, unchecked external calls and gas usage. You get a written report listing each finding, its severity and the fix.
Can you audit a contract I already have?
Yes. Send the code or the contract address and I will review it, report the findings and fix them if you want.
Do you need my private key?
Never. I deploy from a fresh wallet and transfer ownership to your address, or you deploy yourself from the script I provide. Never share a private key or seed phrase with anyone.
Can the contract be changed after deployment?
A standard contract cannot be edited once deployed. If you expect to add features later, I build it as an upgradeable proxy (UUPS or Transparent) so it can be updated safely.
