IMPORTANT

Ensure the following ENV vars are available before running the examples

CALLER_PRIVATE_KEY - Private key of an account that submits the transaction. Follow this guide to create and fund an account with some test tokens on Porcini (testnet) if you don't have one yet.

Examples

bash

# change your working directory to this example first
cd examples/substrate/use-nft

# export all required environments
export CALLER_PRIVATE_KEY=

# creates new collection
pnpm call:createCollection

# update collection info
pnpm call:updateCollection

# mint token(s)
pnpm call:mint

# transfer token(s)
pnpm call:transfer
