Launch crypto custody and card programs on your bank's existing core.

HSM- and MPC-based key management, white-label exchange and custody modules, and simulators your engineers can test with before production keys go live.

Start with one module. Add the rest when you're ready.

Each module runs on the same custody and compliance core, so your second launch builds on the first.

View all solutions

  • Custody & trading

    White-label exchange and custody modules your customers reach from your existing app, with keys under your bank's policy controls.

  • Crypto-linked card programs

    Let customers spend digital assets on Visa and Mastercard rails, with conversion to fiat at the point of sale.

  • Tokenization pilots

    Tokenize a first asset class end to end, from qualified custodian through HSM infrastructure to on-chain settlement.

Keys stay under your institution's control

Your bank sets the policies. The platform enforces them on every key operation and records the result.

  • Keys generated and used inside HSM and MPC boundaries; no single node holds a complete private key
  • Quorum approvals and role-based policies on every key operation
  • Immutable logs for key ceremonies, policy changes, and transfers
  • Fireblocks integration for institutional treasury and transfer workflows
  • Deploy in your cloud, ours, or on-premises
