Stablerail is the business account for companies that run on stablecoins.
Today, companies moving real money onchain face a choice: 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 offers 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:
Fiat sits alongside it as well. Named EUR and USD accounts, SEPA and ACH rails, stablecoin-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 behavior 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, but humans always sign.
Hold, move, and control stablecoins across multiple chains from self-custodial MPC vaults. Set signing quorums and separation of duties, apply policy rules to every payment, and see balances, flows, and counterparty risk in one place. Keys stay with the customer, so no vendor can freeze or lose the funds.
Pay one supplier or three hundred contractors in a single batch across Tron, Solana, Ethereum, and L2s. Every recipient is screened before the transaction is signed, documentation is attached at the point of payment, and gas is sponsored and optimized to minimize costs.
Receive and send EUR over SEPA and USD over ACH using accounts in the company's own name and convert between fiat and stablecoins inside the same platform. No separate exchange, no manual reconciliation, and the same approval and audit controls apply to fiat as to onchain payments.
Screen every incoming and outgoing transaction against sanctions lists and onchain risk data before it is signed, with a hard block on high-risk counterparties. New payers can be routed to quarantine wallets so funds are checked before they reach the main treasury with counterparty risk history tracked over time.
Every payment produces an evidence pack containing the policy in force at the time, the approval chain, the risk report, and the matched invoice. Compliance teams and auditors get a single exportable file per transaction instead of a block explorer link and a reconstruction exercise.
Issue physical and virtual stablecoin-denominated Visa cards with per-card spend limits, MCC controls, and instant freeze. Card balances are funded separately from treasury vaults, so card exposure is capped and never reaches the company's main holdings.
