Archived — an earlier CEN demand loop, superseded on 2026-10-15 by the simpler CEN staking (simple).
This is an archived machine, kept here as honest history. The HRT staking loop was an earlier design for a CEN demand loop. On 2026-10-15 the network replaced it with a simpler, standalone design — CEN staking (simple) — and retired this set. The contracts below remain on-chain but are inert: nothing was ever funded through the loop and no routing crank was ever run.
How it was meant to work: HRT was a plumbing token whose USDC backing was supplied to Aave to earn lending yield. One hundred percent of that yield would route to a five-flavor corpus (the HRT vault), which as a member of the V3 holder-leg family would also earn a pro-rata holder leg. A keyless feeder would then swap each earned cause-flavor directly to CEN — paying trading fees into the endowment LPs — and deliver that market-bought CEN to stakers. Stake and unstake were always open; the corpus could only move earned flavors to the feeder, never redeem or be swept.
Why it was retired: the fresh-start staking line (the NST rebuild) favors one small, independently-reviewable contract over a coupled multi-part loop — the simpler surface can be understood one piece at a time. The successor is CEN staking (simple), which is live and test-proven. See the link below.
This is a description of a retired design, not a live product and not a promise of any return. Every address below can still be verified on-chain for the historical record.
