Oracles
Nerite leverages Api3's OEV (Oracle Extractable Value) oracles as its primary price feed solution. Api3 not only provides Nerite reliable, price data but also generates additional revenue for the protocol through OEV rewards. By capturing value that would otherwise leak to MEV bots and arbitrageurs, Api3's oracles help maximize protocol efficiency while maintaining robust price accuracy.
