Integrate the SEP path once against this testnet mock, and the same code works against any real Stellar anchor later — you only change the network and the home domain. The bank is simulated; the Stellar leg is real testnet USDC.
The whole handoff is two values. Everything else — where to log in, deposit, withdraw, the issuer — is discovered from stellar.toml.

Or open demo-wallet.stellar.org and add asset USDC with that home domain. No API key, no password — the user's key is the identity. Verified with SDF's anchor-tests.
/transactionstellar.toml discovery (SEP-1), /auth (SEP-10), /sep6 deposit & withdraw, /sep12 simulated KYC (no personal data), /sep38 quotes. Non-custodial: the user's key is the identity. Integrate once, ship to any real SEP anchor by changing the home domain. The SEP path →
