# Base Base hosts aarnâ’s yield vault series. âtvUSDC on Base is a USDC vault that routes into Aave, Moonwell, Morpho, and Pendle PT/LP markets to compound base lending yield and add carefully bounded looped carry when possible, while âtvBTC extends the same framework to cbBTC, preserving BTC beta and layering on measured, collateralized yield. The Base deployment is designed for treasuries and long-term holders who want programmable, policy-driven returns on stables and BTC without sacrificing self-custody or taking on opaque leverage structures. The core Base vault contracts are live and audited as part of the aarnâ engine stack, and the first vault, âtvBTC (cbBTC) ([0xdc1900be2316ccf295d003938bed28d621aebf10](https://basescan.org/address/0xdc1900be2316ccf295d003938bed28d621aebf10)) is now **live and open**. The [aarnâ miniapp](https://miniapp.aarna.ai/) is the primary interface to both Base vaults in the initial launch phase, offering deposits, performance tracking, and full on-chain transparency. The miniapp is the Farcaster/Base mini app endpoint. It is designed to be launched from supported Farcaster clients on Base, giving users an in-app way to view and access the same audited Base vaults without leaving the Base/Farcaster environment. The Base vault contracts have been audited by Failsafe. The [audit report](https://drive.google.com/file/d/16EK-59YoFuBfGL4zRR7YBbL9ko35Au7U/view) covers findings, resolutions, and the scope of the review. {% embed url="" %} {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
