eth_uninstallFilter removes a server-side filter you previously created on a Polygon PoS node — whether a log filter, a block filter, or a pending-transaction filter — and frees the resources the node was holding to track it. Each filter consumes memory and is polled with eth_getFilterChanges; calling this method when you are done is the clean way to release that state. On a busy MATIC-fee network where many integrations watch contract logs, releasing idle filters keeps your node footprint small. Send the request to the Polygon mainnet endpoint at https://polygon.therpc.io/YOUR_API_KEY (chain ID 137, 0x89).

false return is not an error — it just means the filter ID was not found, usually because it had already expired naturally. Treat it as a no-op rather than a failure.eth_getFilterChanges polling), but relying on that timeout is fragile; calling eth_uninstallFilter explicitly when you are done is the better practice.Parámetros
