Uniswap v3 Substreams package

Substreams Package Open in DevPod! Open in GitHub Codespaces

Substreams-based Uniswap-v3 Substreams-powered-subgraph.

This module emits EntityChanges, and are written directly to graph-node without any AssemblyScript mappings therein.

This module covers all of the entities of the original v3-subgraph by the Uniswap team. It syncs much faster.

Launch the devpod above and run:

make build
substreams gui map_pools_created \
  -e mainnet.eth.streamingfast.io:443 \
  -t +150

Stream Entity changes

First, authenticate, and run sftoken in your shell session.

This runs the graph_out module against a Substreams cluster:

substreams run https://github.com/streamingfast/substreams-uniswap-v3/releases/download/v0.2.8/substreams.spkg \
  graph_out \
  -e mainnet.eth.streamingfast.io:443 \
  -t +150
