[Polygon Bor v2.7.3 Released, Includes Improvements to Private Transaction Relay] According to Golden Finance, on May 8, the Polygon PoS network execution layer client Bor released version v2.7.3, applicable to the Amoy testnet and mainnet. This is a maintenance update that includes improvements to pre-confirmation and private transaction relay, as well as bug fixes. This update has a significant impact on private transaction users, as private transactions will now enforce a 10-minute Time-To-Live (TTL). If a private transaction is not included in a block within 10 minutes, it will be removed from the private pool and enter the public network. If the transaction is not packaged, users can increase the transaction fee to send a replacement transaction, thereby improving the likelihood of being included in a block.
