Beam Subgraphs Monorepo

This repository contains The Graph protocol subgraphs configured for Beam network.

Included subgraphs:

• blocks - forked from blocklytics/ethereum-blocks
• uniswap-v2 - forked from uniswap/v2-subgraph
• ens - forked from ensdomains/ens-subgraph

Getting started

• install Node.js >=16 and yarn >=1.22
• run yarn from the repository root to install dependencies

The default network names used in this repo are beam and beamtest. Your target graph-node's config must match one of these values. You can find instructions on how to set up your graph-node with Beam below.

You don't need to install graph-cli, since every subgraph package comes with it's own particular setup to use, depending on the version its code was written for. If you'd need it nevertheless, install it using yarn global add @graphprotocol/graph-cli.

CLI

All subgraph packages in this monorepo share the following commands to facilitate the development workflow (the extension :test refers to using Beam testnet):

• codegen[:test]: generate types from ABIs and GraphQL schema
• build[:test]: build TS into WASM and compile subgraph
• index[:test]: create a subgraph on the graph-node (not using create here to avoid clash with yarn create)
• deploy[:test]: deploy the subgraph to the graph-node
• all[:test]: all of the above in sequence

To execute any command for a specific subgraph, use yarn workspace <packageName> <command>, e.g.:

# testnet, step by step
yarn workspace blocks codegen:test
yarn workspace blocks build:test
yarn workspace blocks index:test
yarn workspace blocks deploy:test

# mainnet, using shortcut
yarn workspace uniswap-v2 all

Subgraph customization

To customize any of these subgraphs for other networks, check the following for your package:

• add your network and contract setup in networks.json
  • packages using older versions of graph-cli may have separate network.[networkName].json files
• update node urls and network names in the commands in package.json > scripts (we recommend to introduce your own commands, e.g. build:myNetwork)
• for uniswap-v2 only: see ./src/configs/* for all necessary parameters

Running a graph-node in Docker

• set up a VPS, install git, docker, docker-compose
  • e.g. via sudo apt install git docker docker-compose -y
• clone graph-node
  • git clone --depth=1 https://github.com/graphprotocol/graph-node.git
• update docker-compose.yml in ./graph-node/docker (see also docs)
  • change graph-node > environments > ethereum to look like this: <network name>:<rpc url>, e.g. beam:https://myArchiveRpc.foo
  • update postgress_pass and POSTGRES_PASSWORD to not use the default password
• create a systemd service to run the docker containers automatically
  • create /etc/systemd/system/graph.service, e.g. by running sudo nano /etc/systemd/system/graph.service and pasting the contents below from the clipboard
  • update User and WorkingDirectory to match your setup

[Unit]
Description=graph
Requires=docker.service
After=docker.service
[Service]
Restart=always
User=root
Group=docker
WorkingDirectory=/root/graph-node/docker
ExecStartPre=/usr/bin/docker-compose -f docker-compose.yml down
ExecStart=/usr/bin/docker-compose -f docker-compose.yml up
ExecStop=/usr/bin/docker-compose -f docker-compose.yml down
[Install]
WantedBy=multi-user.target

• enable and run services

sudo systemctl start docker

sudo systemctl enable graph
sudo systemctl start graph

sudo systemctl status graph

Considerations

• an archive node is required to run the graph-node
• do not run service as root/superuser
• exposed admin endpoints should be protected
• SSL needs to be set up (e.g. via nginx reverse proxy + certbot)
