Name your rate. The book fills it.
yDelta is a two-sided orderbook for fixed-rate loans. Lenders post asks, borrowers post bids — when they cross, both sides lock the rate and term. Whatever the book can't fill flows to Project 0, so capital never sits idle.

Post your order
Lenders quote an ask (bank APR + spread). Borrowers quote a bid (max rate + term + collateral). Both rest on the book.
Cross to match
When a bid meets an ask, the engine pairs them. Rate and term lock for the full term — no curve, no drift.
Unmatched never idles
Anything that doesn't cross falls through to Project 0: lenders keep earning the variable floor, borrowers can still draw at Project 0's rate.
Pick a side
Lock a rate, lock a term.
Bid the max APR you'll pay. Your collateral keeps earning Project 0 yield the whole term. If the book can't fill you, Project 0 backfills at its variable rate.
