Developers on Filecoin now have another way to bring the USD price of FIL into smart contracts. On October 22, 2026, RedStone deployed a FIL price feed on the Filecoin mainnet, three days after the network completed the Solstice upgrade, providing an additional on-chain pricing source for applications on the Filecoin Virtual Machine (FVM).
Key points
- The RedStone FIL/USD oracle has gone live on the Filecoin mainnet.
- The price is updated when there is a 0.5% price change, or at least every four hours.
- This service adds another option alongside the existing Pyth and Tellor oracles for FVM.
How does RedStone's FIL price feed work?
The FIL/USD price feed provides a USD-denominated price for FIL, powered by a smart contract running on the FVM. This programmable layer enables developers to build applications on Filecoin, a network best known for file storage.
Oracles bring external information, including asset prices, onto the blockchain for smart contracts to use. RedStone uses a push mechanism: it writes price updates on-chain when predefined conditions are met, rather than waiting for applications to request them.
An update is triggered when the FIL price changes by 0.5%. Even if the price movement is below this threshold, the price source refreshes at least every four hours.
Another oracle option alongside Pyth and Tellor
Filecoin’s FVM now supports oracle services from Pyth and Tellor. RedStone has added a dedicated FIL/USD data source, giving developers more service options and reducing reliance on a single provider.
Developers can choose price sources suited to their applications or combine multiple data sources. This update expands those options rather than introducing oracle services to Filecoin for the first time.
RedStone’s broader oracle infrastructure already covers over 110 chains. Estimates for 2026 suggest that the total value secured by its services ranges between $4 billion and $9 billion; these figures reflect its overall business, not this specific Filecoin deployment.
Lending and derivatives developers gain access to new pricing sources.
Developers building lending protocols or derivative products on the FVM now have an additional available FIL price source. This integration provides these programmable applications with the USD price of FIL.
This deployment follows the Solstice upgrade completed by Filecoin on October 19, 2026. The Solstice upgrade altered the block reward distribution, ended Fil+ DataCap subsidies, and shifted incentives toward paid storage usage.
Filecoin has also been expanding its programmability through the FVM and initiatives such as Filecoin Onchain Cloud. RedStone’s deployment adds pricing infrastructure to this application environment.
Integration Status and Adoption Metrics
Metrics for adopting this price source include: integration with the FVM protocol, the value volume dependent on its data, and the emergence of FIL lending or derivatives markets. These are indicators used to assess adoption and do not represent that adoption has been achieved.
As of the announcement of the launch, no additional partnerships or user metrics related to this integration between RedStone and Filecoin have been disclosed.
