AI agent that scores Solana tokens for rug pull risk and physically blocks risky swaps via smart contract. Not just a warning — an autonomous on-chain enforcer.
Decentrathon 5.0 — National Solana Hackathon 2026 | Colosseum Frontier
Rug pulls on Solana steal billions. $6B+ lost in 2024-2025 (LIBRA, MELANIA, HAWK Tuah, TRUMP, ENRON). 98.6% of Pump.fun tokens are rugs (Solidus Labs).
Every existing tool does the same thing: warn. User ignores warning, buys anyway, loses money.
Solana Trust is the first system that moves from off-chain advisory to on-chain enforcement:
Token Added → AI Scores → Score Published to Solana PDA → Swap Attempt → Smart Contract Reads Score → BLOCK or ALLOW
- Rule Engine — 56 on-chain features, 6 risk categories
- ML Model — XGBoost (ONNX, 407KB, 8MB RAM), trained on 2350 tokens
- AI Agent — GPT-4o-mini reasoning + natural language explanation
- Oracle — Score published to Solana PDA on-chain
- GuardedVault — Smart contract reads AI score and blocks risky swaps automatically
// The core innovation: on-chain enforcement
if token_risk_score.score > vault.risk_threshold {
return Err(ErrorCode::RiskTooHigh.into());
// Swap blocked. Funds safe.
}- Speed: 400ms finality — oracle scores update in real-time, before the rug happens
- Cost: $0.0001 per TX — publishing scores on-chain is economically viable (impossible on Ethereum at $5-50/TX)
- PDA architecture: Program Derived Addresses provide trustless, permissionless score storage that any protocol can read
- Composability: GuardedVault is a Solana program — any DEX, wallet, or DeFi protocol can integrate it as a CPI call
- Ecosystem need: Solana has the highest memecoin/rug activity — this is where the problem lives
| Step | What happens |
|---|---|
| 1 | Connect Phantom wallet (devnet) |
| 2 | Add token address to Oracle |
| 3 | AI agent auto-scores every 90s |
| 4 | Score appears on-chain with Solana Explorer link |
| 5 | Create GuardedVault, set risk threshold |
| 6 | Deposit devnet SOL |
| 7 | Simulate Swap → contract checks score → BLOCKED or ALLOWED |
