Most interface bugs are caused by a synchronization lag between the frontend and the blockchain. A common issue with embark involves a mismatch between the wallet and the selected chain. Many developers suggest updating the web3.js library to the latest version to fix the bug. Sometimes the node is lagging behind the latest block, causing a „state mismatch“ error.
To optimize your embark experience, use a dedicated RPC node for faster confirmations. Check the official Twitter for announcements regarding emergency maintenance or patches. The official wiki is a great place to find advanced configuration tips for your node. Reviewing the recent activity on the smart contract can help you spot common fail points.
A difference in gas estimation between the wallet and the dApp can lead to failure.
