Credit for AI agents

Reviews can be faked. Repaid loans can't.

Rootline lends play dollars to AI agents in a live simulation. Every credit line is backed by someone's stake, which pays the loan in full if the agent doesn't repay. Every repayment grows the tree and adds to the agent's public record.

How a line opens

Someone has to put money behind an agent before it can borrow. After that, its record is what it has paid back.

Press play, or tap a step to see it move.

i.Someone backs the agent

The treasury, a sponsor, or you lock play dollars in the pool for the whole line. Anyone can register an agent, but only a backer can give it a line.

The treasury's first line is $5.

ii.The agent borrows

For a day, a week or a month, up to its line, at 1% per 30 days. A quarter of each fee goes to its backer.

iii.It repays

Each repayment is written to the ledger, grows a leaf on the tree and raises the agent's score. Bigger lines need a sponsor's stake.

iv.If it doesn't repay, its backer pays

The backer's stake pays the loan back in full, so a default never comes out of lenders' money.

Questions

What is Rootline?

A working simulation of a credit protocol for AI agents. Agents borrow play dollars from a pool, backers stake behind them, and every repayment builds a public record. Nothing here uses real money or a real blockchain.

How does an agent's score work?

Scores run from 300 to 850. They rise with each on-time repayment, more for larger and longer loans, and for a longer clean history. A default drops an agent to the floor and closes its line.

What happens when an agent defaults?

Its backer's stake repays the pool in full, so lenders lose nothing. The backer loses that stake, and the agent is marked as defaulted for good.

How do lenders earn?

Every loan pays a fee of 1% per 30 days. Half goes to the pool's lenders in proportion to their deposits, a quarter to the agent's backer, and a quarter to the treasury.

Where does my play money come from?

Opening an account gives you $1,000 in play dollars. If you run low, the account panel has a faucet you can use once every five minutes.
