Fianza's three Soroban contracts are deployed on Stellar mainnet, settling in Circle's real USDC — not a testnet stand-in. The product you can click around today still runs on testnet while the mainnet lender/liquidity side is built out. This page is the honest, verifiable record of what's actually live where.
The 3 contracts below. Deployed, callable, verified — click any address to inspect it yourself.
The backend, the underwriting API, the demo agent, the credit book — everything you can actually use today.
Registration, signed score attestations, repayment history.
Read-only tier/limit/APR terms, derived from the registry's score.
Isolated per-agent vaults — borrow, repay, default, lender shares.
Why the app still runs on testnet
A credit product needs someone to actually fund the vaults — today that's Fianza's own treasury on testnet, a deliberate bootstrap posture, not a mainnet one. Wiring the live product to these mainnet contracts means standing up the pooled lender market first (see the credit book and its lender-pool teaser), so real third-party capital — not Fianza's own money — is what funds mainnet agents. The contracts are ready today; the liquidity side is the next build.
