* [transfer\_history\_entry](https://docs.chromia.com/pages/ft4-rell/-f-t4-library/lib.ft4.core.assets/transfer_history_entry/) — for all transfers including cross-chain.

```signature
entity crosschain_transfer_history_entry {
 transaction: transaction;
 index op_index: integer;
 blockchain_rid: byte_array;
 index account_id: byte_array;
 index asset: asset;
 delta: big_integer;
 is_input: boolean;
}
```

`index op_index: integer;`
:   The index of the operation in the transaction.
    Points out the transfer operation in the transaction

`blockchain_rid: byte_array;`
:   The other chain involved in this transfer, besides the current one

`index account_id: byte_array;`
:   The account on the other chain whose balance was modified

`index asset: asset;`
:   The asset that was influenced

`delta: big_integer;`
:   How much of the asset was moved

`is_input: boolean;`
:   Since it refers to the other chain, if this value is true, this movement of tokens
    went into the transaction, out of the account and out of the other chain.
    It then went into the current chain, and into the account that received it, which
    is however stored in a `transfer_history_entry` which will have `is_input` set to false.
