Check (in the txpool and in the main code) that an EIP-7702 transaction is valid, namely that:

to != nil
len(authorization_list) != 0
authorization.chain_id is uint256
authorization.nonce is uint64
authorization.address is bytes20
authorization.y_parity == 0 || authorization.y_parity == 1
authorization.r is uint256
authorization.s is uint256 and authorization.s <= secp256k1n/2
