Class CrossmintAASDK

Retrieves a wallet for the user. If the wallet does not exist, it will be created.

Notes:

1. The user identifier is used to ensure the same wallet can be retrieved across devices.
2. To interact with different chains, obtain a wallet instance for each chain by invoking this class multiple times.

Sample code if using the default Fireblocks NCW signer:

const wallet = await crossmint.getOrCreateWallet({
  email: "    ",
}, {
  chain: "ethereum",
  signer: {
    type: "FIREBLOCKS_NCW",
    passphrase: "xxxx",
  },
}).catch((e) => {
  if (e instanceof PassphraseRequiredError) {
    // Ask user for passphrase and call again
    return;
  }
  
  console.error("Failed to get or create wallet", e);   
});

@param user Identifier for the user whose wallet to retrieve
@param chain The blockchain for which to retrieve the wallet. A wallet instance can on one chain only, but you can retrieve multiple wallet instances for different chains.
@param walletConfig Configuration related to wallet initialization.
@returns A Wallet instance corresponding to the given user and chain.
@throws PassphraseRequiredError if a passphrase is needed to create a wallet, or to recover it
