Minting a testnet NFT

Before we can test, we need at least one NFT on our account, so let's mint it.

yarn mint

Example of the expected output:

$ tsc && node ./dist/mint.js
{
  requestId: ArrayBuffer {
    [Uint8Contents]: <f7 55 2b 32 37 4c ea 46 1a 40 0c 89 dc 56 8b a3 85 e1 68 8f 12 14 2f 5c 45 27 56 96 f4 79 44 29>,
    byteLength: 32
  },
  response: { ok: true, status: 202, statusText: 'Accepted' }
}
✨  Done in 31.54s.

Listing NFTs on the ICP Testnet

To be sure we're bridging the right NFT, let's see that we have it on the chain:

yarn nft-index

Approving an NFT for Transfer

Before the bridge is allowed to transfer an NFT, it must be given the right to do so:

yarn approve

Transferring an NFT

Make sure to run the steps above before transferring.

yarn transfer

The present repository explains transferring NFTs FROM Dfinity.
Sending TO Dfinity from other chains is as easy as selecting the Dfinity as the target chain & providing a relevat receiver address.
