 The transaction fields `chain_id`, `nonce`, `max_priority_fee_per_gas`, `max_fee_per_gas`, `gas_limit`, `destination`, `value`, `data`, and `access_list` follow the same semantics as [EIP-4844](./eip-4844.md). *Note, this means a null destination is not valid.*
 
 `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. The transaction is considered invalid if the length of `authorization_list` is zero. It is also considered invalid when any field in an authorization tuple exceeds the following bounds:
 
 ```python
-assert auth.all_chains == 0 || auth.all_chains == 1
+assert auth.unchained == 0 || auth.unchained == 1
 assert auth.nonce < 2**64
 assert len(auth.address) == 20
 assert auth.y_parity < 2**8

 At the start of executing the transaction, after incrementing the sender's nonce, for each `[chain_id, address, nonce, y_parity, r, s]` tuple do the following:
 
 1. Establish signed-over chain ID of the authorization.
-    * 1a. If `all_chains` is zero, set `auth_chain_id` to the transaction `chain_id` (which must equal the executing chain's ID).
-    * 1b. If `all_chains` is one, set `auth_chain_id` to zero.
+    * 1a. If `unchained` is zero, set `auth_chain_id` to the transaction `chain_id` (which must equal the executing chain's ID).
+    * 1b. If `unchained` is one, set `auth_chain_id` to zero.
 2. Verify the `nonce` is less than `2**64 - 1`.
 3. `authority = ecrecover(keccak(MAGIC || rlp([auth_chain_id, address, nonce])), y_parity, r, s]`
     * 3a. The `s` value must be less than or equal to `secp256k1n/2`, as specified in [EIP-2](./eip-2.md).
