Ethereum/Polygon のトランザクションを再送するアーキテクチャ背景 When you submit a transaction with a gas price that is too low to be included in the block, the transaction can be pending for a very long time. You might then want to update the transaction's gas price in order to get it mined. This concept becomes a bit more complex when it comes to EIP 1559. https://docs.alchemy.com/docs/retrying-an-eip-1559-transaction にある通り、トランザクションはガス代が安いとマイニングされないことがあります
