The documented migration moves reference-price subscriptions to PolyBolt while leaving the activity topic on RTDS, requiring separate handling of the two connections.

Changing the WebSocket URL alone does not migrate a client. PolyBolt changes authentication, op-based subscription messages, object filters, symbols and heartbeats. Its crypto spot source is Pyth; a USD reference series is not the old Binance USDT quote series. Read full\_accuracy\_value as a decimal string, without the legacy E18 conversion. Preserve subscription snapshots and sequence continuity, and account for retired channels: the old 30-second TWAP has no listed replacement, while live comments are being retired and comment lists remain in REST. ### Who it is for - Developers maintaining legacy RTDS clients. - Crypto and equity applications using reference prices. - Teams updating real-time data connections. ## Data and API methods - **Legacy activity topic** Keep activity on RTDS; PolyBolt has no replacement activity channel. - **Reference-price channels** Use price.crypto and price.equity for supported spot references. - **60-second TWAP** The Chainlink 60-second path maps to price.crypto.twap with window\_seconds=60. - **Authenticated prices** Send CLOB credentials in an auth message before subscribing. - **Snapshots and sequences** Process the snapshot flag and per-channel sequence on subscription. - **Connection health** Handle protocol Ping/Pong, dropped counters, reconnects and close codes. ## Integration tasks ### Migrate reference prices Identify the old topic, authenticate to PolyBolt, choose a supported channel and lowercase USD symbol, then parse full\_accuracy\_value as a decimal string. ### Maintain activity separately Keep the RTDS activity connection while migrating prices and track both connection lifecycles. ## Pricing and total cost The migration guide lists no separate stream subscription price. Valid CLOB credentials are required for PolyBolt price channels. ## API access and setup 1. Inventory the RTDS topics your application uses. 2. For prices, connect to wss://ws-live-v2.polymarket.com/ws. 3. Authenticate, then use op-based subscriptions and object filters. 4. Map btcusdt or btc/usd to btcusd; equity symbols are lowercase. 5. Handle snapshots, sequences, reconnects and closes; documented support needs @polymarket/client 0.11.0 or later. ## Useful links - [Polymarket Discord community]() ### What to check - The spot-price source changes to Pyth USD references. - Do not apply E18 scaling to full\_accuracy\_value. - No replacement is listed for legacy 30-second TWAP. - Live comments retire without a replacement stream; REST comment listings remain. - PolyBolt allows 64 active subscriptions and 20 subscribe frames/second; violations can close the connection.

No. Auth, op messages, filters, symbols and heartbeat handling change too. ### Does every topic move to PolyBolt? No. Activity stays on RTDS. ### Which field preserves precision? Read full\_accuracy\_value as a decimal string. ### Why is btcusdt unsuitable? The new crypto channel expects lowercase USD symbols such as btcusd. In this profile
