There was a problem hiding this comment.
In this strategy, we can only replace the transaction with 10% feeCap bump and 10% tip bump. It might hurt the UX to some extent.
For example, if the user already specify a high enough feeCap but a barely enough tip. And he wants to speed up the inclusion, he has to bump the feeCap as well. If the basefee raises up, then the maximum possible payment is increased.

This has been discussed at the 1559 dev channel, right now this replacement condition seems to be the best choice.

This is now running on |
* replace GasPriceCmp and GasPriceIntCmp with FeeCapCmp, FeeCapIntCmp, TipCmp, TipIntCmp (and update all usages) * update Cost to use FeeCap instead of GasPrice
* add eip1559 status indicator * add DynamicFeeTx to transaction type check * remove underpriced transactions on minimum miner tip increases * require both a fee cap and tip bump for transaction replacement * use tip as secondary comparison criterion for priceHeap sorting
…transaction validation
…e post-EIP-1559 arm of pool.SetMinMinerFee()
