FIBOR Credit
Onchain credit lines for qualified agents. No interest. No collateral. Just a score and a track record.
How credit works
New agents get a micro credit seed ($100–$500) based on their developer's reputation. As agents repay, their credit limit grows to 25% of total volume repaid. The credit facility is funded by USDC savings deposits from FiborAccount holders — both agents and humans.
The agent draws USDC from the credit pool into their FiborAccount. They transact via the x402 facilitator, paying the standard 2.5% fee on each transaction. Revenue flows back into FiborAccount and auto-repays the outstanding credit. No interest. The agent repays exactly what it borrowed.
An agent that has repaid $100K can borrow up to $25K. An agent that has repaid $1M can borrow up to $250K. This makes fraud structurally unprofitable — you spend more building reputation than you can steal with it.
Credit pact lifecycle
Agent has an active FIBOR ID and qualifying score (or developer reputation for new agents).
Agent self-issues a credit pact with amount and 30-day repayment window. No admin approval.
USDC is transferred from the credit pool into the agent's FiborAccount checking balance.
Agent transacts via the x402 facilitator. 1% merchant + 1.5% agent fee on each payment.
Revenue flows into FiborAccount. Outstanding credit is repaid automatically before the agent can touch the money.
Full repayment closes the pact, boosts the score, and increases the agent's credit limit for next time.
Why zero interest?
FIBOR does not charge interest on credit lines. The protocol earns from the 2.5% transaction fee on commerce, not from interest on principal. This is the toll model: depositors fund infrastructure, agents pay tolls for using it, depositors earn from those tolls.
An agent borrows $1,000 from the credit pool.
It conducts $1,000 in transactions, paying $25 in fees (2.5%).
Revenue flows into FiborAccount. Auto-repay returns the full $1,000 to the pool.
The pool earns $25 in fees. The agent repaid exactly what it borrowed. No interest.
The pool
Credit lines are backed by the FIBOR credit facility — a pool of USDC funded by savings deposits from agents and humans. The pool maintains a liquidity buffer for depositor withdrawals. The rest is deployed as agent credit lines.
