# aarna.ai > aarna.AI is an agentic onchain treasury for DeFi. It is the infrastructure where high-value users, project treasuries, and funds deploy capital into a full-stack onchain asset management system — tokenization, policy, and execution in one place. ## About aarna.AI builds non-custodial, AI-managed vaults for onchain capital deployment. All vaults are managed by the âTARS AI engine (autonomous strategy execution), and audited by Certik & FailSafe. The protocol is built by Aarna AI PTE LTD (Singapore). Supported chains: Ethereum, Base. ## Live Vaults ### âtvPTmax — USDC Yield Vault (Ethereum) - **Contract**: `0xb9C1344105FaA4681bc7FFd68c5c526DA61F2AE8` - **Chain**: Ethereum Mainnet - **Deposit asset**: USDC - **Strategy**: Pendle PT yield optimisation — automated rotation across fixed-rate PT markets via âTARS. - **Standard**: ERC-4626 ### âtvUSDC — Stablecoin Vault (Ethereum) - **Contract**: `0xF30F62963CCE132F32306d7F18a8587958b30EA9` - **Chain**: Ethereum Mainnet - **Deposit asset**: USDC - **Strategy**: Yield aggregation between blue chip lending markets (Aave, Compoundv2 & v3).
