Our oracle provider is [Redstone](https://docs.redstone.finance/docs/introduction). RedStone offers flexible Data Feeds with <10s update time perfect for money markets. The infrastructure is well battle-tested and **secures hundreds of millions of USD on mainnets**. Trusted by some of the best protocols in DeFi and supported by well-renowned Builders such as Stani Kulechov (Aave), Coinflipcanada (GMX), Jacob Blish (Lido), Sandeep Nailwal (Polygon), Emin Gün Sirer (Avalanche) and Alex Gluchowski (zkSync).\
\
RedStone oracle uses an innovative model of providing signed data feeds with a transaction. This is far more efficient, as providing additional data to a transaction is very cheap compared to calling another contract. Loanshark contracts check if the data feeds were signed by trusted signers to ensure that data was not manipulated.
