_WHAT WE BUILD

We work with founders building wallets for consumer fintech apps, institutional custody solutions, DeFi platforms, and everything in between.

Full-cycle delivery — from key management architecture to App Store launch

EVM / Solidity

DeFi protocols, token contracts, vesting, governance, vault architecture, escrow, NFT contracts. Ethereum, Polygon, BNB Chain, Arbitrum, Base

Solana / Rust / Anchor

SPL token programs, staking vaults, escrow, DEX logic, reward distribution. Rust-native, not EVM thinking applied to Solana

Token Contracts & Tokenomics

ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-3643 (T-REX), ERC-1400 Vesting, emission schedules, staking rewards, governance mechanics We advise on the model, not just the implementation

DeFi Protocol Contracts

AMMs, lending, yield aggregators, liquidation logic, oracle integrations Built with capital efficiency and security as first-order requirements

Access Control & Upgradeability

Role-based access, multi-sig patterns, timelocks, proxy upgradeability (UUPS, Transparent, Beacon) The decisions that determine whether your protocol survives a key compromise

Bitcoin Script & Multi-Sig

Native Bitcoin Script, P2SH, P2WSH, PSBT, Taproot Most EVM teams have never written a line of Bitcoin Script, we have

_WHAT AUDIT-READY ACTUALLY MEANS

Most teams treat the audit as a finish line — write contracts, ship to audit, get findings, scramble to fix them, slip the launch.

WE TREAT IT AS A STARTING POINT

100% branch coverage is our baseline before anything goes to an auditor
Every function documented, every access control decision explicit
Modular architecture with clear separation of concerns
Invariants defined before tests are written

The codebase, securing $1.7B+ in real assets, received a 10/10 from Hacken. That's not a target we aim for what happens when contracts are written correctly from the beginning.

_HOW DO WE WORK?

The Blockchain development process with the RedDuck — the blockchain solutions company that is worth it, always follows these steps.
Smart contract development workflow illustration
Contract architecture, access control model, upgrade strategy, key invariants, before code is written.
Modular, documented, test-driven - tests written alongside contracts, not after.
Static analysis, invariant testing, edge case coverage before anything leaves our hands.
We work with Hacken and Sherlock, and we prepare codebases that auditors want to read.
Testnet validation, mainnet deployment, ongoing upgrades and new modules.

_FREQUENTLY ASKED QUESTIONS

Duck with question mark
Primarily EVM and Solana, with real depth in Bitcoin Script as well. If you're building on something else, we'll assess it in discovery.
We prepare and coordinate, but don't audit our own code, that's a conflict of interest. We work with Hacken and Sherlock for independent audit.
Simple token + vesting: 2 to 3 weeks. Full DeFi protocol: 8-16 weeks. We scope this clearly in the first call.
Yes, we've designed vesting schedules, emission curves, staking mechanics, and governance structures. We flag structural issues before they become code.
