About this Gig
Thanks for visiting my gig.
I build production-grade DeFi infrastructure across EVM (Ethereum, BSC, Polygon, Arbitrum, Base, Optimism, Avalanche), Solana, TON, and Sui.
Cross-Chain Bridge (Primary) Lock/mint, burn/mint, or HTLC. Move assets between any chains: EVM Solana, EVM TON, EVM Sui, or non-EVM pairs. Supports LayerZero, Wormhole, or custom relayer.
DEX Uniswap V2/V3, PancakeSwap, or custom AMM. Native on Solana (Anchor/Rust), TON (Tact/Func), Sui (Move), or EVM chains.
Swap Aggregator Route across multiple DEXes on any chain. Best price, split orders, low slippage.
Custom Smart Contracts Tokens, staking, vesting, airdrops, bonding curves, lockers. Written in Solidity, Rust (Solana), Tact (TON), or Move (Sui).
Security & delivery Full test suite, docs, verified contracts, 7 days support.
Message me with your source chain, destination chain, and feature list for a firm quote.

FAQ
What do you need from me to start?
Chain(s), bridge type (if bridge required), token standards, custom features, and any UI preferences.
Which chains do you support?
Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Avalanche, Linea, Scroll. Others on request.
Do you fork Uniswap/PancakeSwap exactly?
I use battle-tested patterns but write custom contracts tailored to your fee model, pool types, and tokenomics.
Aggregator — do I need my own DEXes?
No. The aggregator routes through existing DEXes (Uniswap, PancakeSwap, Sushi, Curve). I can also add your own DEX as a source.
Can you add a fee on swaps (like a revenue model)?
Yes — protocol fees, referral fees, or LP fees are configurable.
