Modules

Layer 1: Event Extraction

Layer 1.5: Combined Events

Layer 2: Foundational Stores

Layer 3: Analytics Outputs

Layer 4: Database Sinks

SQL Sink (PostgreSQL)

Setup

# Create database
createdb polymarket_orderbook

# Apply schema
psql -d polymarket_orderbook -f schema.sql

# Setup sink
substreams-sink-sql setup \
  "psql://user:pass@localhost:5432/polymarket_orderbook?sslmode=disable" \
  https://spkg.io/PaulieB14/polymarket-orderbook-substreams-v0.3.0.spkg

# Run sink
substreams-sink-sql run \
  "psql://user:pass@localhost:5432/polymarket_orderbook?sslmode=disable" \
  https://spkg.io/PaulieB14/polymarket-orderbook-substreams-v0.3.0.spkg \
  -e polygon.substreams.pinax.network:443

Example Queries

-- Top markets by volume
SELECT * FROM top_markets_by_volume;

-- Top traders by volume
SELECT * FROM top_traders_by_volume;

-- Recent large trades (> 1000 USDC)
SELECT * FROM recent_large_trades;

-- Market activity over time
SELECT
  DATE(created_at) as date,
  COUNT(*) as trades,
  SUM(taker_amount_filled::numeric / 1e18) as volume
FROM order_fills
GROUP BY DATE(created_at)
ORDER BY date DESC;

Clickhouse Sink

Setup

# Create database
clickhouse-client -q "CREATE DATABASE polymarket_orderbook"

# Apply schema
clickhouse-client -d polymarket_orderbook < clickhouse-schema.sql

# Setup sink
substreams-sink-sql setup \
  "clickhouse://default:@localhost:9000/polymarket_orderbook" \
  https://spkg.io/PaulieB14/polymarket-orderbook-substreams-v0.3.0.spkg

# Run sink
substreams-sink-sql run \
  "clickhouse://default:@localhost:9000/polymarket_orderbook" \
  https://spkg.io/PaulieB14/polymarket-orderbook-substreams-v0.3.0.spkg \
  -e polygon.substreams.pinax.network:443

Example Queries

-- Top markets by 24h volume
SELECT
    market_id,
    sum(total_volume) as volume_24h,
    sum(trades_count) as trades_24h
FROM hourly_volume
WHERE hour >= now() - INTERVAL 24 HOUR
GROUP BY market_id
ORDER BY volume_24h DESC
LIMIT 10;

-- Trader leaderboard
SELECT
    id,
    total_volume,
    trades_quantity,
    total_fees
FROM trader_analytics FINAL
WHERE is_active = 1
ORDER BY total_volume DESC
LIMIT 100;

-- Hourly volume trend
SELECT
    hour,
    sum(total_volume) as volume,
    sum(trades_count) as trades
FROM hourly_volume
WHERE hour >= now() - INTERVAL 7 DAY
GROUP BY hour
ORDER BY hour;
