What Aurum does
Three products. One account.
The same login holds your operating cash, your yield-bearing balances, and your long-term custody. No third-party exchange. No transfer friction. No off-balance-sheet exposure.
Transparent yield.
Bank-managed sweep into U.S. Treasury repo, regulated money funds, and institutional staking with approved validators. Sources are published; pass-through rates are disclosed monthly.
Settle anywhere.
ACH, FedWire, FedNow, and on-chain transfers from one balance. A metal Visa Infinite card for Premier and Private Wealth. No conversion drag between fiat and stablecoin.
Why Aurum
A bank, not a brokerage.
Most "crypto banks" are brokerages with a debit card. Aurum is a chartered depository institution. That difference shapes everything — how we hold your assets, who we answer to, and what you can see on any given day.
We are supervised by the Wyoming Division of Banking and audited annually by a Big Four firm. Client balances are segregated from corporate balances and reconciled on-chain monthly through a Merkle-tree proof you can verify in your account.
