#1 Enrollment failed due to a multiple persons associated to wallet.

Error 'Could not complete your verification due to a duplicate enrollment'

When attempting to enroll, if presented with the following message ‘Could not complete your verification due to a duplicate enrollment’ and the image below, the system has detected a different person who has attempted to enroll on the wallet previously.

To explain further, if [Person 1] attempts to enrol on [Wallet 1] it fails due to environmental conditions, such as lighting conditions, face positioning, etc. If [Person 1] fails enrollment and [person 2] attempts to enrol on [Wallet 1], this will fail on [Wallet 1]. Please contact support@demos.global for advise.

Workaround, if a person is unclear who enrolled on the wallet, the option is to purge the enrollment following the instructions detailed here.

#2 Duplicate wallet warning

If the following error is displayed the Demos system has dectected a person is already '{onboarded}'. If a person is already enrolled {onboarded} and there is another attempt to enroll on another wallet the error displayed below will be displayed. "Our records report the biometrics on the connected wallet are enrolled on a different wallet already"

Example of a wallet which has detected multiple enrollments

Mainnet feature changes

Previously, when a wallet was detected as a duplicate, the 'enroll' button was disabled therefore required Demos team to address. New feature will allow a wallet owner to purge their MeID token, the biometric enrollment and change wallets that may have been tagged as a duplicate.

Revised changes will allow a previously disabled wallet to allow a user to attempt to enroll after a wallet is displaying an error. On success if that person is not detected in the system,

the person will be 'onboarded' onto the wallet with the removal of the error message. Important note : 1 WALLET > 1 ENROLLMENT > 1 MEID TOKEN ON HEMI PERMITTED

The Demos system will not allow anyone to enroll against multiple wallets.

To explain further, if [Person 1] attempts enroll on [Wallet 1] the status will be [onboarded]

If [Person 1] attempts to enroll on [Wallet 2] as that person is already onboarded in the Demos system [Wallet 2] will detect and display an error message.

If [Person 1] wishes to change wallets, there is a procedure which can be followed to clean their enrolled wallet in order to allow a user to change wallets. The process will change status to 'not onboarded' and burn MeID tokens as part of the process. Process Link

Once [Person 1] has cleaned up [Wallet 1], the person can attempt to enroll on another [Wallet 2] including a wallet which was tagged as a duplicate.

Important Note : If a person has cleaned up a wallet and continues to see the following error message the system has detected an attempt from that person in the system on another wallet. Or the purge/delete process has not completed.

"Our records show that the biometrics associated with the connected wallet are already enrolled on a different wallet. If the biometrics have been deleted and you wish to switch wallets, a successful enrollment will clear the error message. However, if you have attempted to enroll on multiple wallets, there is a risk that the warning may not resolve."

#3 RPC Errors

If users experience RPC errors they will be typically related to the blockchain therefore out of the control of Demos.

Recommend checking the following Hemi Network status also https://hemistatus.com/en

#4 Request failed—TypeError’

These errors could be from either the blockchain or a person repeatedly hitting refresh in their browser. This would result in a large number of requests being sent that are blocked due to security rate controls. I recommend using a different browser or attempting to use another time. Modifications have been deployed on the Demos infrastructure to address issues related to the error below.

#5 My wallet has been hacked and require to change wallets

If a person is unfortunate to have their wallet hacked, they will still have access to their wallet to purge their enrollment. The Instructions can be follwed below

#6 [Wallet connection Errors]

If people are experiencing issues connecting Metamask to the Demos website, we recommend using other supported wallets that can use 'Wallet Connect', Rabby, OKX, etc.; all are supported. Metamask deployed changes in December, which have affected its stability.

We are not advising users to create a new wallet address; they can import their private keys into other supported wallets and connect via ‘Wallet Connect’

Common Questions

Q1 : Why do I see a 'verify' option on the UI, I have a MEID token and enrolled.

Response: Verification is an option for continued confidence of wallet ownership for points and campaign validation. On success, a verify a small gas charged is required to provide an on-chain timestamp of the last verify timestamp. Please refer to the following article for additional information.

Q2 : Do I pay gas for a failed verify ?

Response: Wallets is only charged a fee on a successful verify which will result on an onchain timestamp including an update to the UI.
