To check opCode compatibility programatically I use Viem's (@wevm) estimateGas with no "to" and proper "data". However, not only the opCode may be sufficient on "data". To check TSTORE/TLOAD (cancun) compatibility a proper assembly code must be used: 0x5f5c (push0 + tload)

Using cast on the command line to check "cancun" compatibility would be similar. To check "cancun" (tload/tstore/...): cast call --rpc-url <RPC_URL> --create 0x5f5c To check "shanghai" (push0): cast call --rpc-url <RPC_URL> --create 0x5f
