Links an Ethereum wallet address to an existing customer that was created without a wallet. This is the second step of the deferred wallet flow: first create a customer without a walletAddress to receive a referenceKey, then call this endpoint when the end-customer connects their wallet in your application. The endpoint validates that the reference key exists, the customer does not already have a wallet, and the wallet is not already assigned to another customer in the same instance.

​
