Stablerail is the business account for companies that run on stablecoins.
Companies moving real money on-chain face a choice today. Use a custodian and hand over your keys at enterprise prices, or use a wallet and get no controls, no compliance and no audit trail. Stablerail gives both. Keys are generated and held by the customer through MPC, and Stablerail cannot sign or move funds at any point.
On top sits everything a finance team needs to operate. Signing quorums and separation of duties across admin, requester, signer and viewer roles. A policy engine covering self-approval limits, document requirements by threshold, new recipient verification, velocity rules and off-hours controls. AML and sanctions screening on every transaction, incoming and outgoing, included in the subscription. Counterparty management with risk history. Quarantine wallets so funds from new payers are screened before they reach the main treasury.
Fiat sits alongside it. Named EUR and USD accounts in the customer's own entity over SEPA and ACH, USDC-denominated corporate Visa cards with spend limits and MCC controls, invoicing including recurring invoices, batch payouts with gas sponsorship, and yield on idle balances.
Every payment produces an evidence pack: the policy in force at the time, the approval chain, the risk report and the matched invoice. When an auditor or a banking partner asks what a payment was for, it is one file rather than a week of reconstruction.
The agentic layer runs inside the operational core rather than bolted on the side. It extracts payment intent from documents, verifies counterparties, watches behaviour for anomalies, explains every flag and assembles the audit dossier. What it never does is sign, broadcast or bypass policy. Agents can request, AI can check, humans always sign.
