How to get Wallet ID from an address?

Question

I'm trying to use the cardano-wallet API, but most of the endpoints I want to use are based on WALLET_ID parameter.

How can I find out the WALLET ID when all I have is the addr, for example addr1qyxwlgeux7f8t7552p8uh3de8yfakftt3lwmceuzs9jcw0gw3el5uu8gpznfcsthyvuf558epvsmjl2gmmkvax535tjsaglpn2?

Answer 1

Think of cardano-wallet as Daedalus, it can only manage locally created wallets and their addresses and transactions.

If you want to interact with the blockchain as a whole you should be using cardano-cli (I used Lars' Lobster Challenge address as an example instead to have some outputs):

• Get some tech info:

$ cardano-cli address info --address addr1w8433zk2shufk42hn4x7zznjjuqwwyfmxffcjszw5l2ulesdt3jff
{
    "address": "addr1w8433zk2shufk42hn4x7zznjjuqwwyfmxffcjszw5l2ulesdt3jff",
    "base16": "71eb188aca85f89b55579d4de10a729700e7113b325389404ea7d5cfe6",
    "type": "payment",
    "encoding": "bech32",
    "era": "shelley"
}

• Get ADA/tokens balance and Plutus stuff

$ cardano-cli query utxo --mainnet --address addr1w8433zk2shufk42hn4x7zznjjuqwwyfmxffcjszw5l2ulesdt3jff
                           TxHash                                 TxIx        Amount

Answer 2

In JavaScript, from the Nami Wallet PAB demo:

exports.getWalletIdImpl = () => {
  return Promise.all([window.cardano.getUsedAddresses(), window.cardano.getUnusedAddresses()])
    .then(([walletUsedAddresses, walletUnusedAddresses]) => {
      const addresses = walletUnusedAddresses.concat(walletUsedAddresses)
      return require('blake2b')(20)
        .update(Buffer.from(addresses.map(a => a.to_bech32).join('')))
        .digest('hex')
    })
}
