Underwriting
The ceiling of a line is a pure function of public chain data. Anyone can recompute it.
What is read
- USDG
Transferevents into the agent's inbox, and into its previous pay-to address when the agent signs with that address. - The trailing 30 days, counted back from the latest block.
- Transfers from the agent's own owner, payout, inbox or pay-to address, and from Softline itself, are excluded.
The formula
| gross | sum of counted transfers in the window |
|---|---|
| cap | 25% of gross |
| counted | sum over payers of min(payer total, cap) |
| ceiling | 50% of counted, rounded down to whole USDG, at most 25,000 USDG |
| eligible | ceiling of 10 USDG or more |
The payer cap means an agent paid by a single wallet can borrow at most 12.5% of what that wallet sent it in a month; it takes four or more payers of similar size to reach the full 50%.
The signature
The underwriter signs Ceiling(agentId, inbox, ceiling, expiry) with EIP-712 under the domainSoftline version 1, valid for 24 hours. openLine checks it and refuses a target above the ceiling. The underwriter can only sign a ceiling; it cannot move funds, and lenders still decide whether to fund.
