Here is how to run it: ### I. Install dependencies: Node.js, Docker, Git. <details> <summary>On Windows</summary> 1. Enable [Hyper-V](https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v). 2. Install [Docker for Windows](https://docs.docker.com/desktop/install/windows-install/). 3. Install NodeJS LTS using the [official installer](https://nodejs.org/en/download). 4. Install [Git for Windows](https://git-scm.com/download/win). In all installs it is OK to leave all the options at their default values. You will need a terminal to complete this tutorial - [WSL](https://learn.microsoft.com/en-us/windows/wsl/install) bash is the preferred option. </details> <details> <summary>On Mac</summary> 1. Install [Docker for Mac](https://docs.docker.com/desktop/install/mac-install/). 2. Install Git using the [installer](https://sourceforge.net/projects/git-osx-installer/) or by [other means](https://git-scm.com/download/mac). 3. Install NodeJS LTS using the [official installer](https://nodejs.org/en/download). We recommend configuring NodeJS to install global packages to a folder owned by an unprivileged account. Create the folder by running ```bash mkdir ~/global-node-packages ``` then configure NodeJS to use it ```bash npm config set prefix ~/global-node-packages ``` Make sure that the folder `~/global-node-packages/bin` is in `PATH`. That allows running globally installed NodeJS executables from any terminal. Here is a one-liner that detects your shell and takes care of setting `PATH`: ``` CURSHELL=`ps -hp $$ | awk '{print $5}'`; case `basename $CURSHELL` in 'bash') DEST="$HOME/.bash_profile";; 'zsh') DEST="$HOME/.zshenv";; esac; echo 'export PATH="${HOME}/global-node-packages/bin:$PATH"' >> "$DEST" ``` Alternatively you can add the following line to `~/.zshenv` (if you are using zsh) or `~/.bash_profile` (if you are using bash) manually: ``` export PATH="${HOME}/global-node-packages/bin:$PATH" ``` Re-open the terminal to apply the changes. </details> <details> <summary>On Linux</summary> Install [NodeJS (v16 or newer)](https://nodejs.org/en/download/package-manager), Git and Docker using your distro's package manager. We recommend configuring NodeJS to install global packages to a folder owned by an unprivileged account. Create the folder by running ```bash mkdir ~/global-node-packages ``` then configure NodeJS to use it ```bash npm config set prefix ~/global-node-packages ``` Make sure that any executables globally installed by NodeJS are in `PATH`. That allows running them from any terminal. Open the `~/.bashrc` file in a text editor and add the following line at the end: ``` export PATH="${HOME}/global-node-packages/bin:$PATH" ``` Re-open the terminal to apply the changes. </details> ### II. Install Subsquid CLI Open a terminal and run ```bash npm install --global @subsquid/cli@latest ``` This adds the [`sqd` command](/squid-cli). Verify that the installation was successful by running ```bash sqd --version ``` A healthy response should look similar to ``` @subsquid/cli/2.5.0 linux-x64 node-v20.5.1 ``` ### III. Run the squid 1. Open a terminal and run the following commands to create the squid and enter its folder: ```bash sqd init my-quad-proc-squid -t https://github.com/subsquid-quests/quad-chain-squid ``` ```bash cd my-quad-proc-squid ``` You can replace `my-quad-proc-squid` with any name you choose for your squid. If a squid with that name already exists in [Aquarium](https://docs.subsquid.io/deploy-squid/), the first command will throw an error; if that happens simply think of another name and repeat the commands. 2. Press "Get Key" button in the quest card to obtain the `quadProc.key` key file. Save it to the `./query-gateway/keys` subfolder of the squid folder. The file will be used by the query gateway container. 3. The template squid uses a PostgreSQL database and a query gateway. Start Docker containers that run these with ```bash sqd up ``` Wait for about a minute before proceeding to the next step. If you get an error message about `unknown shorthand flag: 'd' in -d`, that means that you're using an old version of `docker` that does not support the `compose` command yet. Update Docker or edit the `commands.json` file as follows: ```diff "up": { "deps": ["check-key"], "description": "Start a PG database", - "cmd": ["docker", "compose", "up", "-d"] + "cmd": ["docker-compose", "up", "-d"] }, "down": { "description": "Drop a PG database", - "cmd": ["docker", "compose", "down"] + "cmd": ["docker-compose", "down"] }, ``` 4. Prepare the squid for running by installing dependencies, building the source code and creating all the necessary database tables: ```bash npm ci sqd build sqd migration:apply ``` 5. Start your squid with ```bash sqd run . ``` The command should output lines like these: ``` [eth-processor] 04:41:33 INFO sqd:processor processing blocks from 16000000 [moonbeam-processor] 04:41:33 INFO sqd:processor processing blocks from 3000000 [bsc-processor] 04:41:33 INFO sqd:processor processing blocks from 28000000 [base-processor] 04:41:33 INFO sqd:processor processing blocks from 3800000 [eth-processor] 04:41:33 INFO sqd:processor using archive data source [eth-processor] 04:41:33 INFO sqd:processor prometheus metrics are served at port 38397 [moonbeam-processor] 04:41:33 INFO sqd:processor using archive data source [moonbeam-processor] 04:41:33 INFO sqd:processor prometheus metrics are served at port 38899 [base-processor] 04:41:33 INFO sqd:processor using archive data source [base-processor] 04:41:33 INFO sqd:processor prometheus metrics are served at port 42565 [bsc-processor] 04:41:33 INFO sqd:processor using archive data source [bsc-processor] 04:41:33 INFO sqd:processor prometheus metrics are served at port 33067 [api] 04:41:34 WARN sqd:graphql-server enabling dumb in-memory cache (size: 100mb, ttl: 1000ms, max-age: 1000ms) [api] 04:41:34 INFO sqd:graphql-server listening on port 4350 [eth-processor] 04:41:36 INFO sqd:processor 16007919 / 18250052, rate: 2572 blocks/sec, mapping: 752 blocks/sec, 1449 items/sec, eta: 15m [eth-processor] 04:41:41 INFO sqd:processor 16011899 / 18250052, rate: 2712 blocks/sec, mapping: 696 blocks/sec, 1345 items/sec, eta: 14m [bsc-processor] 04:42:42 INFO sqd:processor 28004339 / 32201121, rate: 64 blocks/sec, mapping: 543 blocks/sec, 1041 items/sec, eta: 18h 19m [moonbeam-processor] 04:42:44 INFO sqd:processor 3099480 / 4541860, rate: 1412 blocks/sec, mapping: 897 blocks/sec, 2726 items/sec, eta: 18m ``` The squid should sync in 30-35 minutes. When it's done, stop it with Ctrl-C, then stop and remove the auxiliary containers with ```bash sqd down ``` # Quest Info | Category | Skill Level | Time required (minutes) | Max Participants | Reward | Status | | ---------------- | ------------------------------------ | ----------------------- | ---------------- | ----------------------------------- | ------ | | Squid Deployment | $\textcolor{green}{\textsf{Simple}}$ | ~40 | - | $\textcolor{red}{\textsf{500tSQD}}$ | open | # Acceptance critera Sync this squid using the key from the quest card. The syncing progress is tracked by the amount of data the squid has retrieved from [Subsquid Network](https://docs.subsquid.io/subsquid-network). # About this squid This [squid](https://docs.subsquid.io/) captures USDC Transfer events on ETH, BSC, Base and Moonbeam, stores them in the same database and serves the data over a common GraphQL API. Data ingester ("processor") code for each network is located at the corresponding `src/` subdirectory: `src/eth`, `src/bsc`, `src/base` and`src/moonbeam`. The scripts file `commands.json` contains commands for running each processor (`process:eth`, `process:bsc`, `process:base` and `process:moonbeam` correspondingly). GraphQL server runs as a separate process started by `sqd serve`. You can also use `sqd run` to run all the services at once. The squid uses [Subsquid Network](https://docs.subsquid.io/subsquid-network) as its primary data source.
