# Concrete Instance

âTARS Yield Curator for Fixed PT Yields

aarnâ’s framework is validated by the live tokenized vault product, atv, and its core agent, âTARS:

* User Flow: Deposit USDC > mint atv shares - no bridges, approvals, or technical steps. Redemptions are optimized: shares burned for USDC, and the most liquid and efficient route is automatically selected.
* Agentic Allocation: The âTARS agent monitors Pendle PT markets, allocating to the safest, highest APY pools based on policy: concentration, expiry, liquidity, and oracle checks. Policy-driven constraints prevent risky allocations or overexposure.
* Full Transparency: Every agentic move, allocation, rotation, and redemption is public and onchain. Vaults are governed by the treasury policy

All powered by agentic automation, explainable onchain. The baseline linear-programming allocation delivers an average high single to 10% APY, whereas the aTARS dynamic-threshold agent achieved \~14.0%, consistently generating 25-40% higher yields.
