sender

The account ID for a sender account that can start an account registration. It can be in either of these formats:

1. x"01ab...23", meaning this specific account can register new accounts when transferring. Useful for example if this account is a CEX wallet people will get on the chain with.

2. ANY_REF, meaning all accounts can register new accounts.

3. CURRENT_ACCOUNT_REF, meaning the only transfers allowed for this rule are the ones where a certain account from a different chain registers an account with the same ID on this chain. This value will only be accepted if recipient has the same value, and it will not work (despite not throwing any errors) if the sender_blockchain field does not allow cross-chain transfers.

4. a list of values, containing account IDs in the format at point 1, meaning all the account IDs in the list are allowed.
