英文:
Why are polygon transactions being dropped and replaced?
问题
似乎在Polygon网络上，交易可能会自动被取消并替换。
原始交易：0xa67609bacf51ab83b1989e4097b4147574b4e26399bec636c4cfc5e12dfa2897
替代交易：0xec0d501619b5fc9cde6af41df929eeded252138a49965f15a7598bf2e532e555
这里发生了什么？
在以太坊上，我相信只有在有人主动提交一个具有相同nonce但燃气价格更高的交易时，才会发生这种情况。这正确吗？
英文:
It seems transactions on polygon can get automatically dropped and replaced.
original: 0xa67609bacf51ab83b1989e4097b4147574b4e26399bec636c4cfc5e12dfa2897
replaced: 0xec0d501619b5fc9cde6af41df929eeded252138a49965f15a7598bf2e532e555
What is happening here?
On Ethereum, I believe this can only happy if someone proactively replaces the tx by submitting another with the same nonce and higher gas price. Is that correct?

是的，在以太坊上，我相信只有在有人主动提交具有相同nonce和更高gas价格的另一个交易时，才能发生这种情况。
是的，在Polygon和其他EVM链上也是可能的。
发送者可以出于多种原因替换他们的交易。例如，高频交易机器人会不断检查他们的待处理交易是否仍有可能盈利 - 如果交易不会盈利，机器人会用另一个交易替换它。可以是具有重新计算参数的新交易，他们期望该交易能够盈利，或者只是从/到相同地址的交易，这样他们至少不会损失更多资金，只是燃气费用而已。
注意：一旦您发送了交易，就不可能完全从内存池中删除它。这就是为什么它被发送回发送者地址的原因。
或者有时，交易会被指定了不足够的gasPrice的普通用户替换，他们希望通过将gas价格替换为更高的值来加快交易速度。

Yes, and the same is possible on Polygon and other EVM chains.
Senders can replace their transactions for multiple reasons. For example, high-frequency trading bots continuously check if their pending transactions are still likely to be profitable - and if the transaction is not going to be profitable, the bot replaces it with another one. Either with new recalculated params that they expect to be profitable or simply with transaction from/to the same address so at least they don't lose any more funds than just the gas fees.
Note: Once you send a transaction, it's impossible to drop it completely from the mempool. That's why it is sent back to the sender address.
Or sometimes transactions are replaced by regular users that specified insufficient gasPrice and want to speed up the transaction by replacing the gas price with a higher value.
