Autonomous yield optimizer for Solana DeFi. Polls Kamino, MarginFi, and Solend every hour. Reasons with Claude. Rebalances when it's worth it.
Yield farming manually means checking three dashboards, doing the math on gas costs, and second-guessing yourself at 2am.
Flux fetches live rates across every major Solana lending protocol, builds a rate matrix, and asks Claude to reason about the optimal allocation — factoring in utilization risk, liquidity depth, and concentration limits. It only rebalances when the improvement is meaningful. Otherwise it holds.
FETCH RATES → BUILD MATRIX → REASON → ALLOCATE → ACCRUE → REBALANCE
Paper mode on by default. One env var flip for live capital.

| Rule | Detail |
|---|---|
| Min APY gate | Ignore any rate below 5% |
| Rebalance threshold | Only move capital if improvement > 2% APY |
| Max protocol concentration | 50% cap per protocol |
| Utilization guard | Avoid pools above 90% utilization |
| Liquidity floor | Minimum $10k available to exit |
| Protocol | Assets | Notes |
|---|---|---|
| Kamino | USDC, SOL, USDT, JitoSOL | Highest rates, most liquid |
| MarginFi | USDC, SOL, USDT | Good depth, lower utilization |
| Solend | USDC, SOL, USDT, BTC | Longest track record |
| Drift | USDC, SOL | Perp funding rates (opt-in) |
