Live public Cashu mint: free GET https://testnut.cashu.space/v1/info returned HTTP 200, software cdk-mintd/0.18.1, 2 keysets (2 active, units sat/usd). Custodial; see custody. Reachable now is not an endorsement.

Custody warning. Every Cashu mint is custodial: the operator holds the bitcoin behind the ecash, can lose it, freeze it or shut down, and you cannot get it back from anyone else. The software is early. Use small amounts only, an amount you would shrug off losing.
