RedDuck is a blockchain engineering partner. We build DeFi protocols, RWA tokenization systems, wallets, and the smart contracts underneath them — on EVM, Solana, and native Bitcoin.
No over-engineering. Hard problems can have simple solutions, and on-chain the simple one usually wins. A contract ships once and holds real money, so we keep designs easy to follow and easy to verify — a pattern earns its place by solving a problem you actually have.
- rwa — whitelabel RWA platform for NAV-priced tokenized bonds/treasuries and deed-backed assets, with Solidity contracts, compliance controls, Sepolia app, and subgraph indexing.
- near-typegen — extracts ABIs from NEAR contracts and generates typed TypeScript clients, so a wrong contract call fails at compile time instead of on chain.
- SolidityProvider — compile a Solidity contract, get a typed F# API for it. No codegen step, no hand-written DTOs.
- Vesting — a Hardhat template with one vesting contract built three ways: on-chain storage, Merkle proofs, ECDSA signatures. The tests measure what each costs in gas, so you can pick before you commit.
- ICO — a token sale template in Solidity: whitelisting, oracle pricing, vesting. A starting point for a launch rather than a finished product.
- erc20-multisend-template — one token to many recipients in a single transaction, authorized by a single Permit2 signature. Browser-only, no backend.
- gamefi-decentralized-casino — ten games with no house backend, every round settled on-chain with Chainlink VRF.
- ai-tarot-web — your three-card spread is derived from your own transaction hash, so the deck cannot be stacked after you pay. The casino's idea, wearing a sillier hat.
- hedera-regulated-token — Hedera HTS regulated token demo with KYC, freeze, wipe, pause, faucet claims, HashPack signing, and a Cloudflare-ready frontend.
- hedera-audit-trail — Hedera HCS audit trail for verifiable ESG events, off-chain data hashes, and consensus timestamp proofs.
- ecosnap — photograph the litter you picked up, get paid for it. A community vote settles what a camera cannot verify.
Protocol engineering, tokenomics and governance design, security and audit preparation. We own the architecture, not a ticket queue. Discovery comes first, and if it points somewhere other than the original plan, you hear it while changing course is still cheap.
