Custody and safety
KOSH scores 44/100. Licensing: we could not confirm a licence for the card issuer on its own website. No incidents or enforcement actions found in the last 36 months. KOSH (Piers Technology Inc.) says it is a financial technology company, not a bank or a money services business, and that some services are provided by licensed partners it does not name. It says stablecoin holdings sit with regulated custodians.
Tria scores 52/100. Licensing: we could not confirm a licence for the card issuer on its own website. 2026-08-28: An attacker exploited an authorization flaw in an older version of Rain's Solana card contract, which Tria's card programme used, and made $431,945 of unauthorized withdrawals affecting 636 Tria customers. Tria reimbursed affected users in full plus an extra 10%, and Rain says every programme on the vulnerable contract was upgraded. The same exploit hit Avici; about $1.1 million was taken across Rain-powered programmes. Tria's cards work as collateral-backed credit cards at 0% APR. Spending is secured by crypto in the user's own wallet, and a "Liquidation Event" sells collateral if charges go unpaid for one calendar day or the collateral value falls below the balance. International cards are issued by Nimbus, LLC, a Delaware company whose terms link to a privacy notice on legal.raincards.xyz. US cards are issued by "Third National". In Nigeria the card is marketed by BANEX Microfinance Bank, licensed by the Central Bank of Nigeria. Tria (Threely Dimensions, Inc.) says it "is not a bank, money services business, card issuer". No proof of reserves applies because Tria holds no customer assets. We found no official enforcement actions. The August 2026 Rain contract exploit is recorded under incidents.
