About
RedDuck is a Web3 engineering company registered as RedDuck LLC in Kyiv, Ukraine, with a second entity, Redduck Limited, in Larnaca, Cyprus; its team works remotely, mostly across Europe. It started as a smart contract engineering team and now takes on full protocol architecture, from indexers and backend services to front ends. On EVM chains it writes Solidity DeFi protocols (AMMs, lending, yield aggregators, liquidation logic, oracle integrations), token and vesting contracts, governance, vaults, escrow and NFT contracts, including ERC-4626, ERC-3643 and ERC-1400 standards. On Solana it builds Rust and Anchor programs, and it also writes native Bitcoin Script, multi-signature and Taproot flows. Its site also lists work on Sui with Move, TON, Hedera, Injective and Hyperledger, plus zero-knowledge development. Its process covers architecture and invariants before code, test-driven development, internal review with static analysis and invariant testing, a full branch coverage baseline before audit, coordination with external auditors, and mainnet deployment with authority handover and a warranty period.
