Invariant: x * y = k
Output: dy = y - k/(x + dx)
Price: p = y/x
Slippage: dx/(x + dx) * 100%
Utilization: U = borrows / (deposits + borrows)
Borrow Rate: R = base + slope * U (when U < optimal)
Supply Rate: R_supply = R_borrow * U * (1 - reserve_factor)
HF = (collateral * liquidation_threshold) / debt
Liquidation when HF < 1
| Pitfall | Risk | Prevention |
|---|---|---|
| Spot price oracle | Flash loan manipulation | Use TWAP |
| No slippage check | Sandwich attacks | Enforce min output |
| Stale prices | Wrong liquidations | Check updatedAt |
| Reentrancy | Fund drainage | CEI + guards |
# Compare oracle vs DEX price
cast call $ORACLE "latestRoundData()" --rpc-url $RPC
cast call $POOL "slot0()" --rpc-url $RPC
Add minimum output enforcement:
require(amountOut >= minAmountOut, "Slippage exceeded");
