A historical on-chain data analytic view of Idle performance can be found on the Idle Stats page.
The liquidity mining program lasts 2 years since the launch of the DAO (26th November 2020) and 2,340,00 $IDLE are distributed on a per-block basis across all the pools.
$IDLE emission schedule and initial distribution are described here.
Idle implemented 3 lending protocols that have been reviewed & audited several times: Aave, Compound, and dYdX. The protocol has gone through 4 full audits by Quantstamp.
The only control the team retains is the ability to pause minting for idleTokens and rebalancing funds in the event of an emergency. Idle Labs also adopted certain policies to ensure that the Idle Protocol remains decentralized.
Idle is not subject to flash loans, as per design deposit and redeem operations can not be executed in the same block.
Idle is a decentralized yield aggregator protocol, which offers Best Yield and Risk-Adjusted strategies to maximize user returns and optimize risk exposure across DeFi protocols.
Idle is consistently building one of the top DeFi yield aggregation technologies since August 2019, and working with leading protocols like Compound, Aave, dYdX, Maker, Synthetix, Kyber Network. Many DeFi protocols are now using Idle to maximize their yields, like Yearn, Harvest, and Enzyme.
Architecture, codebase, interface, and methods are detailed in the documentation.
