Self-repaying loans: deposit stock tokens, borrow USDG at a conservative LTV, and your collateral is routed to yield that pays the debt down automatically. If yield falls to zero the debt stops shrinking — it never grows on its own. There is no repayment schedule, no maturity date, and Pillar charges no interest: the protocol earns only a share of the yield your collateral produces.

Prices and limits above are read live from the protocol. Loan-to-value limits are set conservatively because equity markets close while your loan stays live. How Pillar handles that risk.
How it works
Three steps. Only the first two are yours.
- Deposit your stock tokens
They become collateral and go straight to a yield vault. Nothing sits idle while it backs your loan, and no oracle is needed to deposit.
- Borrow USDG against them
Up to that market's max LTV, drawn from the protocol treasury. No interest, no schedule, no maturity date — nothing accrues against you.
- The yield pays it down
Anyone can harvest a position. Pillar takes — of the yield; the rest goes onto your debt. You are not required to do anything at all.
Before you borrow
The questions worth asking, answered with the limits included. The longer version is in the risk disclosure.
What happens if the yield goes to zero?
Your debt stops shrinking. It does not grow — Pillar charges no interest and nothing accrues against you — but it does not disappear either. A self-repaying loan repays itself at the speed your collateral earns, and no faster.
Can I still be liquidated?
Yes. Positions are overcollateralised and a position below a health factor of 1.0 can be liquidated. What the contract constrains is how much: it computes the smallest repayment that restores your position to health and reverts anything larger.
You lose a slice rather than the position. That is a constraint in the code, not a policy we promise to follow.
Why is the maximum LTV only 40–60%?
Because equity markets close and your loan does not. A tokenized stock follows a market that shuts on Friday and reopens on Monday, and it can open well below Friday's close with no window in which anyone could have traded out of the way.
No faster oracle fixes that. The only honest response is to lend less against it, which is why a broad ETF is allowed more than a single company.
What does Pillar charge?
No interest, no origination fee, and no early-repayment fee. The protocol takes — of the yield your collateral produces, which means it earns only while your collateral is working.
What happens if a price feed breaks?
New borrowing and collateral withdrawal are blocked, because those are the actions that could exploit a wrong number. Repayment, deposits and the harvest are never blocked — you must never be locked out of making your own position safer.
Can I repay early or take my collateral back?
Any time, at no cost. There is no interest schedule for early repayment to interrupt. Withdrawing collateral only requires the remaining debt to stay within the loan-to-value limit, and pulling principal out never forfeits yield you have already earned.
