About this Gig
Need a smart contract or full DApp shipped properly tested, deployed, and working? That's what this gig is for.
I'm a full-stack blockchain developer with 4+ years building across Ethereum, Solana, Tron, BSC, Polygon, XRP Ledger, and Avalanche. Shipped ERC-20 tokens, SPL programs, TRC-20 contracts, NFT minting sites, staking platforms, and DeFi mechanics for clients across the US, Europe, and Southeast Asia. For larger projects I assemble a team of vetted blockchain developers to deliver faster without cutting corners.
SMART CONTRACTS
- Ethereum / BSC / Polygon / Base / Arbitrum ERC-20, ERC-721, ERC-1155, staking, vesting, DAO, escrow. Solidity + OpenZeppelin + Hardhat.
- Solana SPL tokens, NFT collections, custom on-chain programs in Rust/Anchor.
- Tron TRC-20, TRC-721, USDT integrations, energy mechanics via TronBox.
- XRP Ledger token issuance, trust lines, DEX order placement via XRPL APIs.
FULL-STACK DAPPS
- React, Next.js, or Vue frontend. MetaMask, Phantom, TronLink, WalletConnect integration. Node.js backend, MongoDB or PostgreSQL.

FAQ
Which blockchains do you support?
Ethereum, BSC, Polygon, Solana, Tron, XRP Ledger, Avalanche, Base, and Arbitrum. If you need a different chain, message me first and I'll confirm.
Do you work with existing contracts or only write new ones?
Both. I can extend, fix, or optimize existing smart contracts. Share your code when you message me and I'll review it before you order.
Can I see the contract before it goes to mainnet?
Yes — always. Every project goes to testnet first. You review and approve before anything touches mainnet.
Do you provide the source code?
Yes, full source code is included in every package. You own it completely.
What do you need from me to get started?
A clear description of what your contract needs to do, your target blockchain, and any reference projects you have. A one-paragraph brief is enough — message me before ordering and we'll figure out the right package.

Ahsan helped me with my coding problem and I now have a working solution. But I paid a lot for basically 2 lines of code. I don't know how I should feel about that.
