# Use between contracts

### Use LiquidAccounts between contracts

To enable the usage of LiquidAccounts between contracts, the subscriber contract (contract that wishes to use LiquidAccounts of another host contract) must add the `#define VACCOUNTS_SUBSCRIBER` definition to the smart contract. The subscriber contract must also be staked to a DSP offering the LiquidAccounts service, but this DSP does not need to be the same DSP as the DSP providing services to the host contract. In place of setting the `CHAIN_ID` with the `xvinit` action (detailed [here](https://docs.liquidapps.io/liquidapps-documentation/dapp-network-services/dapp-network-services/liquidaccounts/getting-started-guide/test)), the account name of the host account providing the LiquidAccounts (not the DSP account) must be used in its place. The subscriber contract may also subscribe to a “cross-chain host” in the same manner.
