# ERC721 Watcher
Instructions to deploy a local ERC721 watcher stack (core + watcher) for demonstration and testing purposes using [laconic-stack-orchestrator](../../README.md#setup)
## Setup
* Clone / pull required repositories:
```bash
laconic-so --stack erc721 setup-repositories
```
* Build the core and watcher container images:
```bash
laconic-so --stack erc721 build-containers
```
This should create the required docker images in the local image registry.
* Deploy the stack:
```bash
laconic-so --stack erc721 deploy-system up
```
## Demo
* Find the watcher container's id using `docker ps` and export it for later use:
```bash
$ export CONTAINER_ID=<CONTAINER_ID>
```
* Deploy an ERC721 token:
```bash
$ docker exec $CONTAINER_ID yarn nft:deploy:docker
```
Export the address of the deployed token to a shell variable for later use:
```bash
$ export NFT_ADDRESS=<NFT_ADDRESS>
```
* Open `http://localhost:3009/graphql` (GraphQL Playground) in a browser window
* Connect MetaMask to `http://localhost:8545` (with chain ID `99`)
* Export your MetaMask account (second account) address to a shell variable for later use:
```bash
$ export RECIPIENT_ADDRESS=<RECIPIENT_ADDRESS>
```
* To get the primary account's address, run:
```bash
$ docker exec $CONTAINER_ID yarn account:docker
```
Export it to shell variable for later use:
```bash
$ export PRIMARY_ADDRESS=<PRIMARY_ADDRESS>
```
* To get the current block hash at any time, run:
```bash
$ docker exec $CONTAINER_ID yarn block:latest:docker
```
* Fire the following GQL query (uses `eth_call`) in the playground:
```graphql
query {
name(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
) {
value
proof {
data
}
}
symbol(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
) {
value
proof {
data
}
}
balanceOf(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
owner: "PRIMARY_ADDRESS"
) {
value
proof {
data
}
}
}
```
Balance for the `PRIMARY_ADDRESS` should be `0` as the token is yet to be minted.
* Fire the following GQL query (uses `storage` calls) in the playground:
```graphql
query {
_name(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
) {
value
proof {
data
}
}
_symbol(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
) {
value
proof {
data
}
}
_balances(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
key0: "PRIMARY_ADDRESS"
) {
value
proof {
data
}
}
}
```
* Mint the token:
```bash
$ docker exec $CONTAINER_ID yarn nft:mint:docker --nft $NFT_ADDRESS --to $PRIMARY_ADDRESS --token-id 1
```
Fire the GQL query above again with latest block hash. The balance should increase to `1`.
* Get the latest block hash and run the following GQL query in the playground for `balanceOf` and `ownerOf` (`eth_call`):
```graphql
query {
fromBalanceOf: balanceOf(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
owner: "PRIMARY_ADDRESS"
) {
value
proof {
data
}
}
toBalanceOf: balanceOf(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
owner: "RECIPIENT_ADDRESS"
) {
value
proof {
data
}
}
ownerOf(
blockHash: "LATEST_BLOCK_HASH"
contractAddress: "NFT_ADDRESS"
tokenId: 1
) {
value
proof {
data
}
}
}
```
Balance should be `1` for the `PRIMARY_ADDRESS`, `0` for the `RECIPIENT_ADDRESS` and owner value of the token should be equal to the `PRIMARY_ADDRESS`.
* Transfer the token:
```bash
$ docker exec $CONTAINER_ID yarn nft:transfer:docker --nft $NFT_ADDRESS --from $PRIMARY_ADDRESS --to $RECIPIENT_ADDRESS --token-id 1
```
Fire the GQL query above again with the latest block hash. The token should be transferred to the recipient.
## Clean up
* To stop all the services running in background:
```bash
laconic-so --stack erc721 deploy-system down
```
