substreams-uniswap-v3

Substreams-based Uniswap-v3 Subgraph and Substreams. Still in beta.

The Subgraph-style output hinges on the latest graph-node to implement substreams data sources.

Substreams are consumable directly.

Stream intermediate values and events

• Replace the spkg with the version you would like to use, the current release can be found on Github.

• Replace the StreamingFast api endpoint with the preferred network, a list of chains and endpoints can be found here.

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
