RTDS-to-PolyBolt migration and topic changes.

What is Polymarket RTDS?

RTDS is Polymarket’s legacy real-time data service. Its activity topic remains on RTDS, while reference-price subscriptions are moving to PolyBolt. The distinction matters when maintaining an existing bot: changing only the WebSocket URL is insufficient because authentication, subscription messages, symbols and price encoding also change.

Who it is for

  • Developers maintaining an RTDS integration
  • Crypto and equity applications consuming reference prices
  • Teams updating legacy market-data clients

Research topics
Crypto, Equities
  • Activity stream

    Continue using RTDS for the activity topic; PolyBolt has no replacement activity channel.

  • Reference prices

    Use PolyBolt price.crypto and price.equity for supported spot reference prices.

  • TWAP prices

    The 60-second Chainlink path maps to price.crypto.twap with window_seconds=60.

  • Authenticated price access

    PolyBolt requires CLOB credentials through an auth message before subscriptions.

  • Subscription snapshots

    Process the snapshot flag and per-channel sequence when establishing a subscription.

  • Connection health

    Handle protocol Ping/Pong, dropped counters and close codes in the new client.

Workflows with Polymarket RTDS

Migrate a crypto feed

Identify the legacy topic, authenticate to PolyBolt and map it to a supported channel. Convert symbols to lowercase USD pairs and read full_accuracy_value as a decimal string.

Keep an activity integration working

Retain the RTDS activity connection while migrating only the price subscriptions. Track the two connection lifecycles separately.

Pricing and total cost

No separate stream subscription price is listed in the migration guide. PolyBolt price channels require valid CLOB credentials.

Getting started

Before you start: The new crypto spot source is Pyth; a Binance USDT quote and a USD reference are not the same series.

  1. Inventory the RTDS topics used by the application.
  2. For prices, connect to wss://ws-live-v2.polymarket.com/ws.
  3. Authenticate, then send the documented op-based subscription with an object filter.
  4. Map btcusdt or btc/usd to btcusd; use lowercase equity symbols.
  5. Handle snapshots, sequence continuity, reconnects and close codes.
  6. Use @polymarket/client 0.11.0 or later for the documented PolyBolt support.

What to check

  • The new crypto spot source is Pyth; a Binance USDT quote and a USD reference are not the same series.
  • Do not apply the old E18 fixed-point conversion to full_accuracy_value.
  • The legacy 30-second TWAP has no listed replacement.
  • Live comments are being retired without a replacement stream; comment listings remain available through REST.
  • PolyBolt allows 64 active subscriptions and 20 subscribe frames per second; policy violations can close the connection.
