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 used, the current release can be foubd on Github

• Replace the streamingfast api endpoint with the preffered network, a list of chains and endpoints can be found here

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

Hack on it

Build substreams-uniswap-v3

$ cargo build --target wasm32-unknown-unknown --release
[...]
$ substreams run  -e api-dev.streamingfast.io:443 substreams.yaml graph_out -t +150
[...]
try it :)

Pack everything to release

substreams pack substreams.yaml
