Proof
of
Reasoning.

The first protocol where AI agents prove their thinking on-chain — before touching your money. Every decision written permanently to Solana. Verifiable. Immutable. Accountable.

How it works
01
log_decision

The AI agent writes its reasoning, proposed allocation, and confidence score to a permanent Solana account. Signed by the agent key. Immutable.

must confirm before step 2
02
execute_rebalance

Capital moves only after the reasoning is confirmed on-chain. The smart contract validates a matching decision log exists. No log, no rebalance. The transaction reverts.

blocked without step 1
03
verify

Every decision is a permanent Solana account anyone can read. Check the reasoning. Audit the math. The agent is accountable — forever.

This is not a feature. It is a constraint enforced by the smart contract.

Other AI agents

Move your money behind closed doors. You hope it worked. You can't verify why.

TEND agents

Write reasoning to Solana before touching your money. You read why. Then they act.

What if the reasoning is wrong?

You saw it before it executed. It's on-chain forever. Full accountability — not a dashboard, a blockchain record.

The accountability primitive for AI finance.
