eth_newPendingTransactionFilter creates a server-side filter that watches for incoming pending transactions on Base — Coinbase's OP Stack rollup where gas is paid in ETH — and returns a hex filter ID. Polling that ID with eth_getFilterChanges returns the hashes of transactions that entered the node's mempool since your last poll. On Base, transactions flow to the sequencer for ordering, and the ~2s block time means pending hashes move into blocks quickly. Create the filter against https://base.therpc.io/YOUR_API_KEY (Base mainnet, chain ID 8453 / 0x2105); it takes no parameters.
