Bitnuk builds, integrates and advises on wallet, custody-tooling and tokenisation software for fintechs, banks and Web3 businesses. Delivered to your stack — you operate the infrastructure and control the keys. Production-proven engineering, not slideware.
Why Bitnuk
Signing policies, quorums and air-gapped ceremonies designed in from day one — not retrofitted.
Fireblocks, BitGo or self-hosted — we integrate whatever fits your risk model, not a preferred vendor.
Screening hooks, travel-rule readiness and audit-ready logging woven into every delivery.
A decade of group fintech engineering behind live fiat and on-chain rails, in one operational stack.
Software solutions
