Framework for ICRC7 NFT implementation for Internet Computer

Simple NFT

add next to dependences in Cargo.toml

uncensored-greats-dao = "0.1"
serde = { version = "1", features = ["derive"] }
serde_json = "1"
candid = "0.10"

to create NFT struct TestToken with symbol TT and name TestToken in src/lib.rs add

use serde::{Deserialize, Serialize};
use uncensored_greats_dao::{Icrc7, Metadata, Storage};
use candid::CandidType;

#[derive(
    CandidType, Clone, Hash, Default, Serialize, Deserialize,
)]
pub struct TestToken {
    pub name: String,
    pub description: Option<String>,
}

impl Metadata for TestToken {
    fn metadata(&self) -> String {
        serde_json::to_string(&serde_json::json!({
            "name": self.name,
            "description": self.description
        }))
            .unwrap_or_default()
    }
}

#[derive(Icrc7, Storage, Deserialize, Serialize, Default)]
#[icrc7(token_type = "TestToken")]
#[icrc7(symbol = "TT")]
#[icrc7(name = "Test Token")]
pub struct TokenCollections {}

build and deploy to test network

rustup target add wasm32-unknown-unknown
cargo install candid-extractor
cargo build --release --target wasm32-unknown-unknown --package test_token
candid-extractor target/wasm32-unknown-unknown/release/test_token.wasm > test_token.did

dfx start --clean --background
dfx deploy test_token

creating token

dfx canister call test_token create_token \
  "(record{
      token=record {
              name=\"test\";
              description=opt\"test description\"
      };
   })"

mint created token

dfx canister call test_token mint \
    "(record{
        token_id=1;
        holders=vec{record{owner=principal\"$YOU\"}}
    })"
