What happened
BNB Chain executed the Osaka/Mendel hard fork at 02:30 UTC on April 28, the latest in a sequence of upgrades aimed at raising the throughput ceiling on BNB Smart Chain. Per CryptoNews, which flagged the activation in its morning coverage, the headline target is 20,000 transactions per second, a roughly tenfold jump from the chain's prior steady-state throughput. The fork bundles client-level changes that compress block propagation and tighten the gas-pricing model.
Validators were given a multi-week window to upgrade their nodes ahead of the activation block. As of the open in Asia, BNB traded at $620. 65 with no signs of a chain split or stalled finality, the two failure modes traders had been watching for.
Why it matters
Throughput is the only number that matters for a chain pitching itself as the cheap, fast alternative to Ethereum mainnet. BNB Chain has been losing share to Solana and to the Base L2 in DEX volume and active addresses since late 2025, and the Osaka upgrade is the technical answer to that drift. A working 20,000 TPS ceiling, even if real-world utilization sits well below it, changes the marketing pitch for builders weighing where to deploy.
The headline looks bullish. The flow picture is more cautious. BNB is still 11% below its February high, and the price reaction so far has been a hold, not a breakout.
Traders want to see the upgrade actually run under load before paying up for the token.
Market impact
BNB sits at $620. 65, with the technical map laid out clearly in CryptoNews's pre-fork breakdown. The pivot is $633.
