supeeerpower-uniswap-v2

Uniswap V2 Substreams for Ethereum, BNB Chain, and Base: factory PairCreated events and Sync events on those pairs.

Overview

This package indexes Uniswap V2 from each factory's deployment. It decodes factory PairCreated and Sync events on those pairs, including creates and Sync in the same block. Output is typed protobuf for substreams run / GUI.

Pick the chain with --network mainnet, --network bsc, or --network base.

Network	Factory	initialBlock
mainnet	0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f	10000835
bsc	0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6	36111192

Modules

Name	Kind	Output	Description
map_pair_created	map	proto:uniswap.v2.v1.Events	Factory PairCreated events (pair_created).
store_pairs	store	proto:uniswap.v2.v1.PairCreated	Pair metadata keyed by pool:<address> for Sync filtering.
map_events	map	proto:uniswap.v2.v1.Events	PairCreated plus Sync on those pairs, including same-block creates.

Prerequisites

• Substreams CLI
• Rust with wasm32-unknown-unknown (rustup target add wasm32-unknown-unknown)
• A Substreams API key from The Graph Market (substreams auth or SUBSTREAMS_API_KEY)

Quick Start

# Build WASM into ./target (override CARGO_TARGET_DIR if your environment sets it)
CARGO_TARGET_DIR=./target cargo build --target wasm32-unknown-unknown --release
substreams pack

# Ethereum
substreams run substreams.yaml map_events \
  --network mainnet \
  -s 10000835 \
  -t +1000 \
  -o jsonl

# Base
substreams run substreams.yaml map_events \
  --network base \
  -s 6601915 \
  -t +1000 \
  -o jsonl

# BNB Chain
substreams run substreams.yaml map_events \
  --network bsc \
  -s 36111192 \
  -t +1000 \
  -o jsonl

Use map_pair_created to inspect factory creates only. substreams gui substreams.yaml map_events --network mainnet -s 10008355 is useful for browsing decoded events.

First PairCreated is shortly after deployment on each chain: Ethereum around 10008355, Base around 10526493, BNB Chain at 36111192.
