2. Verify the chain id is either 0 or the chain's current ID.
3. Verify the code of `authority` is either empty or already delegated.
4. Verify the nonce of `authority` is equal to `nonce`.
5. Refund the sender `PER_EMPTY_ACCOUNT_COST - PER_AUTH_BASE_COST` gas if `authority` exists in the trie.
6. Set the code of `authority` to be `0xef0100 || address`. This is a delegation designation.
7. Increase the nonce of `authority` by one.
8. Add `authority` to `accessed_addresses` (as defined in [EIP-2929](./eip-2929.md).)

If any of the above steps fail, immediately stop processing that tuple and continue to the next tuple in the list. It will in the case of multiple tuples for the same authority, set the code using the address in the last occurrence.
