Product / Treasury

    A stablecoin treasury your finance team can actually run

    Hold USDC and USDT in self-custody, move them under a signing quorum, and leave an evidence trail behind every payment — without a wallet browser extension in sight.

    Custody, controls and evidence in one account

    Everything a treasury needs to move stablecoins the way it moves money in a bank — approvals, screening and a record that survives an audit.

    Keys you own

    MPC shares are held by your organisation. Stablerail cannot sign for you, and at quorum you can export the keys and leave.

    Signing quorum

    Set who can approve, how many are required and above which amount. Enforced at signing time, not in the interface.

    Screening before release

    Every recipient address is sanctions and on-chain screened before a payment can be signed. High risk fails closed.

    One balance, many rails

    The same balance funds on-chain payouts, SEPA and ACH transfers and corporate card spend.

    Quarantine addresses

    Route unknown inbound funds into a quarantine address, screen the source, then sweep into treasury once cleared.

    Evidence per payment

    Screening dossier, approver, written reasoning, invoice and transaction hash — exportable in one pack.

    From KYB to first payment in days, not quarters

    2. 02
      Create the treasury

      Key shares are generated and distributed to your named signers.

    3. 03
      Set policy

      Self-approval limits, quorum thresholds and document rules per amount.

    4. 04
      Pay and export

      Screen, approve, sign and hand your auditor the evidence pack.

    The controls sit under the signature, not over it

    A wallet with a policy page still lets one person sign. Here the rules are part of signing, so they cannot be clicked past under pressure.

    • Payments above a self-approval limit cannot be signed alone.
    • A flagged recipient blocks release until an admin records a decision.
    • Policy edits require quorum and are logged with the previous value.
    • Every approval carries a name, a timestamp and written reasoning.
    • Key export at quorum means no lock-in to the platform.

    Frequently asked questions

    Who holds the funds?

    You do. Keys are split into MPC shares held by your organisation, so no Stablerail employee can move funds and you can export your keys at quorum if you ever leave.

    Which networks and assets are supported?

    USDC and USDT on Ethereum, Base, Arbitrum, Polygon, Solana and Tron, with more added on request.

    How are approvals enforced?

    Thresholds live in the policy engine and are enforced at signing time, not in the interface. A payment above your self-approval limit cannot be signed until the required approvers have signed.

    What does an auditor get?

    An evidence pack per payment: the screening dossier as it stood, who approved it, their written reasoning, the invoice attached and the on-chain transaction hash.
