About TEND

Proof of Reasoning on Solana

What is TEND?

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, Credible Finance, Kamino, and OnRe is the first use case — but the primitive applies to any AI agent managing assets.

How it works

01
Decision logged on-chain
The AI agent analyzes yield conditions and writes its reasoning and proposed allocation to the blockchain.
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
Bucket share holders earn yield proportional to their position. NAV per share updates reflect real returns.

Built for Colosseum Frontier

TEND is a submission for Colosseum Frontier 2026. The protocol is live on Solana Devnet. Proof of Reasoning is a new primitive: 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.

Architecture

On-chain
Anchor program on Solana managing buckets, allocations, decisions, and borrows.
Agent
TypeScript loop that analyzes yields, logs decisions, and executes rebalances.
Frontend
Next.js app for depositing, browsing buckets, and exploring decisions.
