Custody, stablecoins, and ramps — same ledger.
MPC custody, stablecoin settlement, and fiat on/off-ramps through one set of primitives. Bridge chain and bank without leaving your reconciliation behind.
const payout = await aureus.payouts.create({
from: "acct_treasury",
destination: "0x9f4c…a93f",
amount: 2500000,
asset: "USDC",
network: "base",
});
console.log(payout.settlement); // "on-chain"- MPC custody

Keys you can trust, without holding them
MPC wallets with policy-based controls and no single point of compromise. Custodial when you want it, self-custody patterns when you need them.
- MPC key management
- Policy-based controls
- Multi-chain support
- No single point of failure

- USDC, USDT, PYUSD and more
- Chains
- Ethereum, Base, Solana, Polygon
- Ramps
- Fiat on / off, KYC-gated
- Ledger
- On-chain events post as entries
Bridge fiat and chain in one motion
On- and off-ramp with compliance built in, so a customer funds in dollars and settles in stablecoin — or the reverse — through one balanced flow.
- Fiat on / off-ramps
- KYC / Travel Rule
- Crypto checkout
- Unified reconciliation
Answers, plainly.
MPC custody with policy controls, offered custodially or in self-custody patterns. There is no single key to lose or leak.
Major stablecoins across Ethereum, Base, Solana, and Polygon, with more added by demand. Coverage is listed on the Global page.
On-chain events post to the same double-entry ledger as bank rails. A fiat-in, stablecoin-out flow is a single balanced transaction.
Compliance is built into ramps and transfers — KYC, sanctions screening, and Travel Rule data where required, screened in real time.
