# Map New Chain to Mainnet

{% hint style="warning" %}
It is important that this step be done last after a valid stake has been setup on the mainnet as well as the other previous steps or else the account may not be listened for.
{% endhint %}

### Map New Chain to Mainnet

To map a new chain’s account to the EOS mainnet, navigate to the contract that has deployed the `dappservicex.cpp` contract and perform the `setlink` action.

* owner {name} - name of account on the new chain to link, using services
* mainnet\_owner {name} - name of account on mainnet, staking to services

Example cleos command:

```
cleos -u $NEW_CHAIN_NODEOS_ENDPOINT push transaction '{"delay_sec":0,"max_cpu_usage_ms":0,"actions":[{"account":"dappservicex","name":"setlink","data":{"owner":"liquidxcnsmr","mainnet_owner":"natdeveloper"},"authorization":[{"actor":"liquidxcnsmr","permission":"active"}]}]}'
```

In short you have run the `adddsp` and the `setlink` action on the new chain’s `dappservicex` account and the `addaccount` action on the EOS mainet’s [`liquidx.dsp`](https://bloks.io/account/liquidx.dsp) account.

The new chain account now has the ability to access any service staked to by the mainnet account.
