solc-0.8.10 is not recommended for deployment
Pragma version0.8.10 (#5) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
