signature verification in evm(solidity)

[Dmytro-yakymuk]

maybe there are some cases of using signatures from your examples in evm contracts?
what are the verification options? i just know ECDSA.recover(hash, signature)
from @openzeppelin/contracts/utils/cryptography/ECDSA.sol

where there is v value

if (signature.length == 65) {
            bytes32 r;
            bytes32 s;
            uint8 v;
            // ecrecover takes the signature parameters, and the only way to get them
            // currently is to use assembly.
            /// @solidity memory-safe-assembly
            assembly {
                r := mload(add(signature, 0x20))
                s := mload(add(signature, 0x40))
                v := byte(0, mload(add(signature, 0x60)))
            }
            return tryRecover(hash, v, r, s);
    } else {
    return (address(0), RecoverError.InvalidSignatureLength);
}
