Oracle Risk
The pool uses Pragma's WBTC/USD price feed.
The Pragma oracle is a native Starknet oracle system that secures over USD 200m across all major projects on Starknet.
It is fully decentralized in that it does not rely on off-chain infrastructure. Instead, data providers directly push prices on-chain and aggregation is done by the data consumer directly.
Smart contract risk

The Pragma smart contracts have been audited by Nethermind and both the source code and audit report are publicly available.
Price composition & source diversity
The oracle price is computed as the Median over the most recent data points available for the various Pragma providers.
Oracle fail-safes
The pool uses Vesu's autonomous Emergency features with the following requirements on Pragma's price feeds:
- a minimum of 3 price sources
- a maximum of 4 hours price update frequency
If any of these safety checks are violated, the pool will autonomously enter a pause mode protecting users from untrusted oracle prices.
