We will perform a backend infrastructure upgrade on November 3, 2020 at 19:00 UTC. This upgrade brings two changes to the Ethereum RPC API that users may need to take action for:
- the "from" argument in eth_call requests will now be required (it was previously optional)
- calls to eth_call, eth_estimateGas, eth_sendRawTransaction on Mainnet, Rinkeby, Ropsten and Görli that cause the EVM to execute a REVERT operation will return an error response that includes the revert reason as a string
See this page as well as our Community forum for more information and updates.
