# Cabal > Cabal is a DeFi protocol building cross-ecosystem, AI-optimized yield vaults with verifiable on-chain yield via "Proof of Yield". ## Proof of Yield POY is a ZK-proven inference technology developed by Cabal that enables trustless solvency verification. It addresses trust and solvency issues seen in protocols like Stream Finance (which became insolvent without detection) and Veda (opaque strategies). The thesis behind POY is that institutional capital requires certainty rather than trust. ## Vaults - [sxINIT Vault](https://app.thecabal.xyz/vaults/sxinit): Deposit xINIT to earn staking boost + bribes - [USDC-INIT LP Vault](https://app.thecabal.xyz/vaults/cabal-usdc-init-lp): LP vault with compounding + bribes - [xINIT-INIT LP Vault](https://app.thecabal.xyz/vaults/xinit-init-lp): Earn swap fees + incentives - [Delta Neutral INIT Vault](https://app.thecabal.xyz/vaults/delta-neutral): EVM vault for delta-neutral USDC yield strategy - [Cabal iUSD Vault](https://app.thecabal.xyz/vaults/cabal-iusd): EVM vault earning iUSD lending APY + protocol incentives - [xSLP Vault](https://app.thecabal.xyz/vaults/xslp): Strat vault — deposit iUSD to earn optimized yield on Strat LP positions ## Core Products - [Staking](https://app.thecabal.xyz/staking): Liquid staking for HYPE, SOL, ETH, and INIT - [Bribes](https://app.thecabal.xyz/bribes): Rollup incentives and voting power - [Vaults](https://app.thecabal.xyz/vaults): AI-optimized yield vaults organized by asset (stables, ETH, BTC, HYPE) crossed with strategy (lending, funding rates, DeFi yield).
