The moving reference can reveal off-hours collateral declines without ensuring a buyer for seized assets.

Chainlink says Aave's institutional lending platform Horizon is using its new weekend pricing service, giving tokenized stock collateral a reference that keeps moving while traditional exchanges are closed. The service was announced Oct. 29 and starts with high-volume U.S. equities, according to Chainlink's announcement.

The off-hours price comes from derivatives markets. During regular, extended and overnight sessions, Chainlink 24/7 uses its existing weekday data. When the underlying market closes, it draws quotes from multiple perpetual-futures venues, where derivatives linked to the asset continue trading. That reference reflects those markets' prices, rather than transactions on a closed stock exchange.

Chainlink says it filters stale inputs, limits outlier influence and joins the different sessions into one continuous series. Lending protocols receive the prices through onchain Data Feeds.

For a borrower, the consequence depends on how the feed enters collateral calculations. Where the moving reference is integrated into the market's risk rules, a weekend decline can reduce the value supporting a loan before the underlying exchange reopens. A position could cross its liquidation threshold during that window, rather than waiting for the reopening price update.

Horizon is a separate institutional instance of Aave. Only participants qualified and allowlisted by the collateral's issuer can supply its tokenized real-world assets and borrow against them. Its stablecoin pools, including USDC, RLUSD and GHO, accept liquidity from unrestricted suppliers. Collateral requirements and liquidation thresholds depend on the underlying asset.
