Export Wallet

Export a user's custodial wallets to non-custodial wallet, to do so, retrieve mnemonics.

Before you begin

Let's start 🚀

  1. Use the /wallet/export with an RSA key in the body.
const keyPair = await window.crypto.subtle.generateKey(
    {
      name: 'RSA-OAEP',
      modulusLength: 4096,
      publicExponent: new Uint8Array([1, 0, 1]),
      hash: 'sha-256'
    },
  true,
  ['encrypt', 'decrypt']
);

const privateKey = keyPair.privateKey;
const pubKey = await window.crypto.subtle.exportKey('jwk', keyPair.publicKey);
{
  "pubKey": 
    {"alg":"RSA-OAEP-256",
    "e":"AQAB",
    "ext":true,
    "key_ops":["encrypt"],
    "kty":"RSA",
     "n":"zLd3GbxqykWHqxb2i_8SGmMJsuB7gQ97gwSI8iPW8o6xn3G4Mrcxg4yVi96cF_vcP2Pfpp9OsQZtikRGyTU9yl0yPF2x22voCr-iREcx3WB98BajCp60lAJ0VEw1g3qy-L1PMF7tGP5ItYC6SExYBeCj76RtJ4iutI6xqbHW7TosCEcZ2D3xAkG1alKh6G-fz02eAMFQ4X_zsnuiA5lfLYn6UpfJoITG0rYfu_wK8koKVsEccBeqfAJaYzXRXRm5YpF9tS4FiNkOSMPbt_V8qcq4F8mJqiERcJ1htyPzML2wZBzFvIXAcPlFVAUuUunbrP9N0iCTJkfCwMbFIw0Snqx8nzu2iakjUml4Yv-O_Rl-0p3KLVq38de10QMz1s5u3floeCqKK8GNyd5MVazXX-nbYaySLpS_Q90gCYPZpUYCV2QU640Ff_frHOIkhrQK4c40eUYPqX6Rf8KUixzQ3tPpVBipkEO1k60G6umyhJcbdcVmKgAiKWu7IHYNBK6A2d9gEJh1JaM22o_Dj7nzXcGJp9KnlsHQeHrT_6jlaWeoib9U9JjRySuL3gYzyb8xxI8XfMT02ceRAWWjFcBiUKoCpf-pMxURuY56nNWkFlfcceq2rfZW6MuIhWJZ9cjWLrDxmYpoqG7IkWdK58l4fNV4sZkHDMKO4134YAccgtc"}

}

📌

Pair of keys is used: a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt it.

Result:

200Mnemonics are returned.
400Not authorized. You must be authenticated.

  1. Decode cipher.
const mnemonicBuff = await window.crypto.subtle.decrypt(
  { name: 'RSA-OAEP' },
  privateKey,
  Buffer.from(exportRes.cipher, 'base64')
);

const dataView = new DataView(mnemonicBuff);
const mnemonic = new TextDecoder('utf-8').decode(dataView);
