# Etherscan

1. You need to approve your CHSB to be spent by the migrator.

On the CHSB [contract](https://etherscan.io/token/0xba9d4199fab4f26efe3551d490e3821486f135ba#writeContract), select "Write Contract", use the method `approve` and pass as parameters:

* spender: `0xaA854688caAB725fe17b7D21b46fDA5AF365985a`
* value: \<your amount of CHSB with 8 decimals>

For example, to migrate 100 CHSB, you have to put the value `10000000000` (100 followed by 8 zeros).

2. You can migrate!

On the migrator [contract](https://etherscan.io/address/0xaa854688caab725fe17b7d21b46fda5af365985a#writeProxyContract), select "Write as Proxy", use the method `migrate` and pass as parameters:

* amount: \<your amount of CHSB with 8 decimals>

This is the same amount that you passed before. Once the transaction is executed, your BORG will be automatically sent to your wallet.
