BNB Chain has officially announced that the Greenfield network is currently facing compatibility issues with the MetaMask browser extension, affecting some features, including bucket creation on Dcellar. The issue stems from the MetaMask extension's recent upgrade of its middleware library to the latest version, which implements stricter EIP712 signature verification rules. The BNB Chain team is actively working on a hot fix to address this issue and is expected to release a fix on September 23.
