Aave Horizon uses perpetual futures to price stock collateral on weekends
Chainlink says the approach can flag off-hours declines in tokenized equity collateral, though it does not guarantee a buyer for seized assets.
Aave Horizon, the lending market Aave has positioned around institutional and real-world asset collateral, is leaning on perpetual futures to mark tokenized stock positions while regular equity markets are shut, according to Chainlink. The oracle network described the setup as a way to keep a moving price reference in place during periods when conventional exchange data is unavailable.
Tokenized equities can change hands around the clock, but the underlying shares they track only trade during market hours. That gap leaves lending protocols without a fresh reference price for collateral over weekends and holidays — the window the perpetual futures feed is intended to cover.
A pricing signal, not a liquidation guarantee
Chainlink noted a limitation to the design: a moving reference price can surface a decline in collateral value outside normal trading hours, but it does not by itself ensure there will be a buyer for assets once they are seized and liquidated. That distinction matters for protocols that accept market-linked collateral, where the ability to sell a position quickly underpins the safety of the loan book.
The detail arrives as crypto lenders continue to explore tokenized funds and equities as collateral, a trend that brings traditional market hours into contact with always-on settlement. How such assets are priced and unwound outside trading sessions remains an open design question for the sector rather than a settled practice.
