About TEND

Proof of Reasoning on Solana

What is TEND?

TEND runs your crypto like a hedge fund — except the fund managers are AI agents, their reasoning is public, and you get a Telegram or email notification every time they move your money. A sentinel agent audits every decision before it executes.

TEND introduces Proof of Reasoning — a smart contract pattern that forces AI agents to write their thinking permanently to Solana before any capital moves. The on-chain program enforces this at the instruction level: no reasoning logged, no rebalance executes. The transaction reverts. This creates the first verifiable, immutable record of AI decision-making in DeFi. Yield management across JLP, JupLend, Kamino, OnRe, and Meteora is the first use case — but the pattern applies to any AI agent managing assets.

How it works

01
Decision logged on-chain
The AI agent analyzes yield conditions and writes its full reasoning and proposed allocation publicly before any capital moves.
02
Execution follows decision
Only after the decision is confirmed on-chain can the rebalance execute. This two-step pattern ensures full transparency.
03
Yield distributed to depositors
Vault depositors earn yield proportional to their position. NAV per share updates reflect real returns.

Live on Solana

TEND is live on Solana mainnet. Proof of Reasoning is a new standard: verifiable AI decision-making enforced at the smart contract level. The two-step pattern (log reasoning, then execute) cannot be bypassed — not by the agent, not by the protocol team, not by anyone.
