aerodrome-v2

Aerodrome V2 Substreams for Base: factory PairCreated events and Sync events on those pairs.

Overview

This package indexes Aerodrome V2 on Base from block 3200559 (factory deployment, 2023-08-28 02:41 UTC). It decodes the factory PoolCreated event (Uniswap V2 PairCreated equivalent) and Sync events on those pairs, including creates and Sync in the same block. Output is typed protobuf for substreams run / GUI.

Factory: 0x420DD381b31aEf6683db6B902084cB0FFECe40Da. Aerodrome Sync is Sync(uint256,uint256), not Uniswap V2's Sync(uint112,uint112).

Modules

Name	Kind	Output	Description
map_pool_created	map	proto:aerodrome.v2.Events	Factory PoolCreated events (pair_created).
store_pools	store	proto:aerodrome.v2.PairCreated	Pair metadata keyed by pool:<address> for Sync filtering.
map_events	map	proto:aerodrome.v2.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

substreams run substreams.yaml map_events \
  --network base \
  -s 3200559 \
  -t +1000 \
  -o jsonl

Use map_pool_created to inspect factory creates only. substreams gui substreams.yaml map_events -s 3200559 is useful for browsing decoded events. The first PoolCreated is shortly after deployment (around block 3204872).
