+Transaction is considered invalid if authorization list items can't be decoded as:
+* `chain_id` and `nonce`: u64 number.
+* `address`: 20 bytes array.
+* `y_parity`: single byte.
+* `r` and `s`: 32 bytes array.
+
 The fields `chain_id`, `nonce`, `max_priority_fee_per_gas`, `max_fee_per_gas`, `gas_limit`, `destination`, `value`, `data`, and `access_list` of the outer transaction follow the same semantics as [EIP-1559](./eip-1559.md).
 
 The `authorization_list` is a list of tuples that store the address to code which the signer desires to execute in the context of their EOA.
