It’s the peak of Base Season 2026. You’ve found the next 100x gem, you click “Swap,” and then the dreaded notification appears: [RPC Error]: Transaction underpriced. While you’re manually adjusting gas, the price has already doubled. This error isn’t a failure of the network; it’s a failure of your wallet’s gas estimation. Here is how to stay ahead of the curve.

Why is your Transaction “Underpriced”?
On Base (and other L2s) in 2026, gas dynamics have evolved:
- EIP-1559 Volatility: The
baseFeePerGascan spike 10x in seconds during high-demand blocks. - Mempool Competition: Bots are constantly outbidding retail users with higher
maxPriorityFeePerGas. - RPC Lag: Your wallet might be getting stale gas data from a congested public RPC node.
The Technical Fix: Professional Gas Overrides
Stop relying on “Market” settings in your wallet. In 2026, you need to manually “Overprice” to ensure inclusion.
