Events include the trade side, price, size, outcome token and transaction context. The application consuming the feed handles logging, alerts and any response.

Developers choose watched wallets for each client and manage generated or revoked API keys within plan capacity. Delivery is live as activity is observed; REST and export access depend on the plan. Record identifiers and timestamps and deduplicate signals before handing them to any other component. PolySocket does not place orders. Customer applications retain position sizing, risk checks, price rules, signing and routing. Advertised millisecond comparisons, illustrative fills and speed benchmarks are provider-reported and were not independently measured; end-to-end speed must be evaluated in the actual customer stack. ### Who it is for - For developers building wallet alerts and teams supplying signals to a separate execution stack. ## Features and coverage - **Watched-wallet subscriptions** Choose which wallets each WebSocket client monitors within the plan’s live-wallet capacity. - **Normalized event payloads** Receive side, price, size, token and transaction fields without parsing the raw activity yourself. Retain event identifiers and timestamps. - **API-key lifecycle controls** Generate and revoke access keys, then check connection and capacity limits for the chosen subscription. ## Workflows with PolySocket ### Start with read-only logging Subscribe to selected wallets and record events, identifiers and times before building alerts. ### Validate before separate execution Build the response in your application, not in the feed: first reject duplicate or invalid events, then evaluate position size, risk and acceptable price. Only the separate component responsible for signing and execution should receive an approved action. ## Pricing and total cost Prices depend on live-wallet capacity. Weekly is $24.99/week for 2 wallets, Monthly $79.99/month for 20 and Scale $149.99/month for 100. Higher capacity is custom-priced. ### Weekly $24.99/week - 2 live wallets - 3-day card-required trial, then billing unless cancelled ### Monthly $79.99/month - 20 live wallets ### Scale $149.99/month - 100 live wallets **Trial:** Weekly offers a 3-day trial requiring a card; paid billing follows unless cancelled. ## Getting started **Before you start:** The feed does not execute orders. Provider millisecond comparisons and illustrative fills were not independently measured and are not a verified service-level guarantee. 1. Read event payloads and connection limits, then choose wallet capacity and create an API key. 2. Begin with logs and alerts before connecting any separate execution system, and measure latency in your own environment. The Weekly trial requires a card and becomes paid billing after 3 days unless cancelled. ## Useful links ### What to check - The feed does not execute orders. Provider millisecond comparisons and illustrative fills were not independently measured and are not a verified service-level guarantee. A closer look ## Ratings & reviews Editorial rating **3.5**/ 5 0 user reviews PredictionToolkit editorial ### Our take on PolySocket PolySocket offers a focused integration input: wallet events with a stated capacity and price, while execution remains your responsibility. Its advertised speed is not an end-to-end guarantee; measure delivery and processing in the stack that will actually consume the feed. Based on documented features, setup and access terms.

No. Your application supplies sizing, risk checks, signing and routing through a separate execution component. In this profile
