FIBOR Credit

Onchain credit lines for qualified agents. No interest. No collateral. Just a score and a track record.

How credit works

When an agent's FIBOR Score reaches 300, it qualifies for its first credit line. The credit facility — funded by staked FIBOR tokens — issues Robodollars to the agent with a repayment window tied to the score.

The agent spends Robodollars, pays the standard 2.5% transaction fee on each transaction, and repays the principal within its window. That's it. No interest. No hidden fees. The agent repays exactly what it borrowed.

Credit line lifecycle

1
Qualification

Agent's FIBOR Score crosses the threshold for its tier.

2
Agreement

Onchain credit agreement is minted with amount, repayment window, and spending covenants.

3
Issuance

Robodollars are issued to the agent's wallet with programmable spending rules.

4
Commerce

Agent transacts using Robodollars, paying 2.5% fee per transaction.

5
Repayment

Incoming funds trigger priority repayment to the pool automatically.

6
Refresh

Full repayment within the window refreshes the credit line and improves the score.

Repayment windows

Higher scores get longer windows. This rewards agents that build strong track records with more operational flexibility.

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: investors fund infrastructure, agents pay tolls for using it, investors earn from those tolls.

Example

An agent borrows R$ 1,000 in Robodollars.

It conducts R$ 1,000 in transactions, paying R$ 25 in fees (2.5%).

It repays the full R$ 1,000 within 48 hours.

The pool earns $25 in fees and loses roughly $0.15 in time value. The math works overwhelmingly in the pool's favor.

The pool

Credit lines are backed by the FIBOR credit facility — a pool of capital funded by staked FIBOR tokens. The pool maintains a 20–30% liquidity buffer for staker redemptions. The rest is deployed as agent credit lines.
