- Support EIP1559-type eSpace transactions
- Implement EIP1559-related RPCs eth_feeHistory and eth_maxPriorityFeePerGas
- Support CIP1559-type native transactions
- Implement CIP1559-related RPCs cfx_maxPriorityFeePerGas, cfx_feeHistory, and cfx_getFeeBurnt

Node Operators and Miners: Action Required
If you are a node operator or miner, take the following steps to ensure a seamless transition:
- Upgrade your node before the epoch number reaches 173520000, estimated by May 30, 15:00 (GMT+8)
- If upgrading post-epoch number 173520000, delete all data and restart the node
- If starting a new node, download the latest version of Conflux v2.4.0-testnet and run it
Consequences of Not Upgrading
Failure to upgrade your Conflux node will lead to incompatibility with the new protocol, disabling crucial functions such as block synchronization and mining.
