/vaults/{vaultId}/{blockchain}/{network}/link-address

Through this endpoint, users can link addresses from Smart Vault to the Station address with the station address responsible for paying gas fees on behalf of all linked addresses. The linking process does not require approval.

Linking an address is an on-chain transaction and requires fee which will be paid from the station address in the Smart Vault. Linking is recommended only after having assets on this address which you want to transfer, linking is one timer operation per address..

Completing this step is required before using the station address.

Linking the address is allowed only for Smart Vaults.
