This ADR describes how cheqd/Cosmos account keys can be imported/exported into identity wallet applications built on Evernym VDR Tools SDK.
Client SDK applications such as need to work with cheqd accounts in identity wallets to be able to interact with the cheqd network ledger.
For example, an identity wallet application or backend application would need to pay network transaction fees for writing . This may also need to be extended in the future to support .
Cosmos SDK uses . This can be replicated using standard crypto libraries to carry out the same steps as in Cosmos SDK:
Functionality will be added to VDR Tools SDK to import/export cheqd accounts using mnemonics paired with the --recover flag as done with Cosmos wallets.
Not applicable, since this is an entirely new feature in VDR Tools SDK for integration with the new blockchain framework.
Adding/recovering cheqd accounts in VDR Tools SDK will follow a similar, familiar process that users have for Cosmos wallets.

The mnemonic above is assumed to be a pre-existing one . The "passphrase" above is user-defined, and defaults to blank if not defined.
Mnemonic import/export can be achieved using pre-existing packages and .
Using these pre-existing libraries, cheqd accounts can be recovered using the standard for Cosmos SDK chains described below:
