BNB Chain has told node operators to complete a required software update before the Osaka/Mendel hard fork hits the mainnet on April 28.
Summary
- BNB Chain told node operators to install BSC v1.7.2 before the launch of the Osaka/Mendel hard fork.
- The April 28 mainnet update follows the testnet activation and adds stability, gas limits, and finality.
- BNB Chain said that outdated configurations and poor binary replacement could cause nodes to go out of sync.
The network said operators should move to BSC v1.7.2 and remove outdated configurations to keep nodes running normally.
BNB Chain developers said node operators must complete the update before the Osaka/Mendel hard fork goes live on the BSC mainnet. The network scheduled the update for April 28 at 2:30 am UTC.
The advisory said that operators should replace binaries correctly and clean up old configuration fields. The team said those steps are necessary to prevent nodes from “going out of sync” during the upgrade.
The message focuses on preparing the infrastructure before the fork date. It also shows that the upgrade is not optional for operators who want their nodes to remain aligned with the chain.
The deadline comes as BNB Chain moves from testnet preparation to a full mainnet launch. That change typically puts more attention on validator and node performance across the network.
The Mendel upgrade adds BEP-652, which brings EIP-7825 to the BNB chain via a protocol-level gas cap for each transaction. The limit is set at 16,777,216 gasoline.
That change means that all nodes will reject transactions that exceed the limit in the same way. BNB Chain He said this method is more reliable than the previous soft limit model that traders could treat differently.
The broader network upgrade includes nine BEPs in total. BNB Chain also said it adopted seven of the 13 Ethereum proposals tied to Faceincluding six that required a hard fork and client-side RPC change.
The network did not adopt the other six proposals due to architectural differences. It also added two BNB chain-specific upgrades via BEP-657 and BEP-648.
Testnet launch occurred before mainnet launch
BNB Chain activated Osaka/Mendel hard fork on the BSC testnet on March 24 in block 88.379.325. The developers said the testing phase improved block construction, transaction handling at scale, network stability, and execution accuracy.
BEP-657 limits when blob transactions can be included based on the block number. BEP-648 aims to reduce latency and accelerate finality in the network.
The mainnet launch now depends on operators completing the required upgrade in time. The latest alert shows that BNB Chain wants nodes to be fully prepared before the April 28 hard fork begins.
