ckNFT

Problem Statement

NFT’s on ICP are superior as they store the asset data WITH the token. However, EVM chains capture most of the trading liquidity for now.

Our Solution

ckNFT is a direct integration of an ICRC7-based NFT wit evm blockchains such as Bitfinity or Ethereum using ERC-1155 standard.

Prerequisites

DFINITY Canister SDK
Node.js

yarn install:all
# or
npm run install:all

Running Local Internet Computer

To start the local Internet Computer environment, run:

yarn dfx:start
# or
npm run dfx:start

Deploying to the Local Internet Computer

Deploy your the backend canister to the local Internet Computer by running:

yarn deploy icrc7 --argument '(record { tx_window=24; permitted_drift=2; name="Icrc7 Token"; symbol="ICRC7"; minting_authority=principal"'$(dfx identity get-principal)'";royalties=null;royalties_recipient=null;description=opt "ICRC7 Standard Token";image=null;supply_cap=null;cknft_eth_address="0x22c64ea6fa6c67b9331cc45967a257456b03d518";ecdsa_key_name="dfx_test_key";})'
# or
npm run deploy icrc7 --argument '(record { tx_window=24; permitted_drift=2; name="Icrc7 Token"; symbol="ICRC7"; minting_authority=principal"'$(dfx identity get-principal)'";royalties=null;royalties_recipient=null;description=opt "ICRC7 Standard Token";image=null;supply_cap=null;cknft_eth_address="0x22c64ea6fa6c67b9331cc45967a257456b03d518";ecdsa_key_name="dfx_test_key";})'

yarn identity:deploy
# or
npm run identity:deploy

Running the Next.js App

Minting NFT

Finally, to mint the ICRC7 NFT:

# Mints token
dfx canister call icrc7 icrc7_mint '(record{
  id=10;
  name="Icrc7 10";
  description=opt "10th token of the collection";
  image=null;
  to=record{
  owner=principal"2vxsx-fae";
