Insufficient Gas
Most common failure. Your wallet needs enough ETH (or the relevant chain's gas token) to cover the fee.
Check your balance on the relevant chain. If low, transfer ETH and retry. Current gas prices: Etherscan gas tracker. Keep a small buffer — prices fluctuate between estimation and execution.
Slippage on Uniswap
When swapping thUSD on Uniswap v4, price movement between submission and execution can cause the transaction to revert.
Fix: Increase slippage tolerance in swap settings (e.g., 0.5% → 1%). For large swaps, split into smaller transactions to reduce price impact. If you see "price impact too high," the trade size is too large relative to pool liquidity.
Pending Transaction
If submitted but not confirming:
Gas price too low: Network congestion increased after submission. Most wallets let you "speed up" by resubmitting at a higher gas price.
Nonce conflict: Earlier pending transactions must confirm first. Wait or cancel them through your wallet.
Reverted Transaction
If the block explorer shows "reverted" or "failed": the on-chain operation was rejected. Common causes include the token approval not being set before a mint/stake, or contract limits being reached. Check the error message on the block explorer.
