Address book

Feature Description: 1. Only one sub-account user can be designated as the address book manager at any given time. 2. Only the address book manager can add addresses to the address book in the CoinSign App's address list and sign them, ensuring these addresses are protected from tampering. 3. Both the address book manager and other sub-account users can select addresses from the address book in the CoinSign App when performing dispatch operations.

1. First, designate a sub-account as the address book manager by following these steps: > In the main account's CoinsDo platform, navigate to "Sub-account" page and click the "CoinSend" action button for the desired sub-account to open the CoinSend Settings > Set "Address book management permission" to "Yes" > For "Address book management device" option, select the sub-account's CoinSign device and submit the changes

   

2. In the “Address book” page of CoinSend center, you can verify the current address book manager and signing device's ID.

   

3. The address book manager must first share their public key with other sub-account users for signature verification. Please refer to the steps and images below: > The address book manager logs into the CoinSign App and taps the sub-account name at the top left to open the settings screen > Tap “Address list” > On the “Address list” screen, tap the “Address book public key” icon at the top right or tap "View public key" > In the “Address book public key” screen, tap the QR code icon beside “Verification public key” > On the “Verification public key” screen, tap “Share” to share the public key QR code with other sub-account users. Note: If new sub-accounts are added later, the address book manager must share the public key with them as well. Note: If the address book manager or their CoinSign device is changed, the address book manager must share the updated public key with all sub-account users.

   

4. Other sub-account users must configure their signing devices to verify the address book using the manager’s public key. Please follow the steps and images below: > The sub-account logs into the CoinSign App and taps the sub-account name at the top left to open the settings screen > Tap “Address list” > On the “Address list” screen, tap the “Address book Public Key” icon at the top right, or tap “Configure public key” in the warning prompt > On the “Address book public key” screen, tap the scan icon next to “Verification public key” to scan the manager’s public key QR code (or copy and paste the manager’s public key into the “Verification Public Key” field), then tap “Save” > If the warning prompt no longer appears on the “Address book public key” screen, it means the verification setup is complete.

   

5. The address book manager can add and verify address book addresses. Please refer to the following steps and images: > The address book manager logs into the CoinSign App and taps the sub-account name at the top left to open the settings screen > Tap “Address list” > On the “Address list” screen, tap “Add” > On the “Add address” screen, enter the recipient name, select the coin type, and input the recipient address (you can paste it manually or tap the scan icon next to the address field to scan an address QR code). Then tap “Save” to add the address to the address book Note: To also add the address to “My list,” you can enable the “Add to my list” option > Return to the “Address list” screen and go to the “Address book” tab. The newly added address will show a “Address not signed” warning. Tap “Sign” to sign all currently unsigned addresses in one action. Then enter your identity private key password to complete the signing Note: We recommend signing all addresses on the address book to reduce the risk of address tampering.

   

6. Addresses on the address book that have been verified by the address book manager will display the address book manager's account name. To delete an address from the address book, tap the trash can icon next to the address.

7. If the address book manager or a sub-account user selects a unsigned address book address in the CoinSign App’s "Add dispatch record" screen, a risk warning will appear, alerting the user that the address has not been signed and may be unsafe. Note: We recommend using only verified address book addresses and reminding the address book manager to sign all addresses on the address book to reduce the risk of tampering.

8. Navigate to CoinSend center > Address book page. In the "Address book list" section, you can view details of addresses added by the address book manager (such as the signer's account name, last signature time, address network, etc.). Click the "View Signature" option next to a signed address, then paste the address book manager’s public key to verify the signature.

   

9. In the Logs section of Address book page, you can view the operation history of address book addresses, such as the address name and the type of action performed by the address book manager.
