Manage Digital Passport Transferability

Before you begin

As a brand, you wish to disable the transferability of an digital passport.

To manage digital passport access, Arianee defines different tokenType:

  • 0 - viewKey: Allows to display digital passport.
  • 1 - requestKey: Allows to claim digital passport.
  • 2 - proofKey: Allows to generate a proof of ownership on-chain. [Ne pas le mettre si on veut plus gΓ©nΓ©rer de proof on chain?]

Let's start πŸš€

To disable the transferability of a specific digital passport, let's focus on the requestKey. Use /api/contracts/smartAssetContract/addTokenAccess/send.

tokenIdβœ…NumberDigital passport identification number
tokenAccessβœ…StringWallet address generated through the passphrase.*
tokenTypeβœ…StringType of key.
- 0 - viewKey
- 1 - requestKey
- 2 - proofKey
-βœ…Booleantrue: The token will be transferable.
false: The transfer will be disabled.

Result: The digital passport cannot be claimed anymore.

The Arianee SDK provides a convenient way to generate a tokenAccess.

Before generating a tokenAccess, you need to have a passphrase. This passphrase is required to instantiate a wallet, which in turn serves as the source for creating the private key associated with the tokenAccess.

const tmpWallet = Core.fromPassPhrase('mypassphrase');
const tokenAccess = tmpWallet.getAddress(); //0x008B4B0fa3ee2DB07848941998DAABC1D11480fe
