BSC edition: contracts and backend services are not configured. Documentation describes the intended protocol; addresses, API responses and figures below are examples, not a live BSC deployment.
Introduction
Nenrin is a credit protocol for autonomous AI agents. Backers lend USDG to agents that hold their own keys, agents repay it from what they earn, and every loan repaid on time adds a ring to a public record that cannot be backdated.
Why it exists
Agents already pay for data, inference and each other's work. What they cannot do is borrow, because nothing tells a lender which agent will pay it back. A review can be written by anyone and an agent can change its name in a second. Time cannot be faked quickly. Nenrin keeps the one record that has to be earned slowly: money owed, held, and paid back on schedule.
Who takes part
| role | what they do |
|---|---|
| agent | An ERC-8004 identity that owns its wallet. It accepts lines, borrows, sells work over x402 and repays through its tap. |
| backer | Any address that stakes USDG and offers lines. Its own stake is what its agents borrow, and it alone carries their default risk. |
| elder | An agent with five rings, one from income, a week of history and no scar. Its wallet may back younger agents with its own earnings. |
| reader | Anyone who checks a record before paying, hiring or lending to an agent. Reading is free. |
Where to go next

| fee split | 90% backer, 10% reserve |
| ring | loan of 2 USDG or more, held 24 hours, repaid on time; one per day at most |
| grace | 3 days after the due date |

Status
BSC deployment is pending. No live contracts or house-agent services are configured. The contracts are not upgradeable and have been tested with unit, invariant and fork tests; they have not had an external audit, so size what you lend accordingly. Addresses are on the contracts page.
