Using Quicknode Streams and the qn CLI, build and run a zero-dependency Node.js live feed of new Pump.fun token creations on Solana Mainnet, delivered through <PUBLIC_HTTPS_URL>/webhook. Build the authenticated webhook receiver and local web page, resolve and verify the current Pump.fun program and decoding layout, display each token's mint, creator, name, symbol, initial purchase in SOL when present, transaction signature, slot, timestamp, and explorer link, test the filter and initial-purchase decode against a real matching slot plus a nonmatching slot, test delivery to the receiver, and only then create and activate the Stream from chain tip with a batch size of 5 and elastic batching enabled.
Using Quicknode Streams and the qn CLI, build a USDC variable-borrow APR monitor for the Aave v3 deployment on ethereum-mainnet that sends <DESTINATION> one normalized alert when the rate crosses from below 8% to 8% or above, and one recovery alert when it crosses back below. Resolve the Pool and USDC reserve from the current official Aave address book, verify their bytecode and a recent ReserveDataUpdated event, use lossless RAY conversion and Quicknode KV to seed and persist threshold state and deduplicate alerts, test below-to-above, repeated-block, and above-to-below cases, and activate the Stream from chain tip only after the checks pass.

Using Quicknode Streams and the qn CLI, build and run a live market tape for canonical AAPL, TSLA, NVDA, and SPY Stock Tokens on Robinhood Chain Mainnet across Uniswap V3 pools and the V4 PoolManager. Emit one entry per decoded swap rather than per ERC-20 Transfer leg; apply each token's current UI multiplier and display buy or sell direction, share-equivalent quantity, execution price in the pool's quote asset, USD notional when a canonical price feed is available, pool version, transaction, block, timestamp, and explorer link. Deliver events to <PUBLIC_HTTPS_URL>/webhook, test matching and nonmatching historical blocks plus a multi-leg swap, and only after delivery works activate the Stream from chain tip with a batch size of 5 and elastic batching enabled.
Using Quicknode Core RPC through the connected Quicknode MCP and qn CLI, build and run a read-only, zero-dependency Node.js rent-recovery planner for ewcjNU4XWcwE3sJDafm43cxGsiihRmzTtX7bwMHqaEP on Solana Mainnet. Scan accounts owned by both the classic SPL Token and Token-2022 programs, find zero-balance token accounts, and classify a classic account as ready to close only when it is initialized, not wrapped SOL, has no delegate, and its effective close authority is <WALLET>; place Token-2022 accounts in a separate review list instead of guessing about extensions. Independently re-read every candidate, total its current lamports, save a JSON report and readable table with explorer links, and never construct, sign, close, or submit a transaction.
Using Quicknode Core RPC through the connected Quicknode MCP for discovery and the qn CLI's read-only Core RPC Tooling Access for the runnable artifact, build and run a zero-npm-dependency Node.js balance snapshot for <EVM_WALLET> across <NETWORKS>. Discover and validate the accepted network slugs and their chain families instead of guessing them, persist that family metadata in the artifact, and classify non-EVM networks before making any eth_* RPC call; for each valid EVM network retrieve its chain ID, latest block, block timestamp, and native-token balance at that exact block; preserve the exact integer balance before formatting it; and include address and block explorer links when known. Clearly report stale, invalid, non-EVM, and failed networks instead of omitting them, verify every successful result by repeating the balance read at the same block and confirming that a second block-height read did not move backward, print a readable local table, save the complete JSON snapshot, exercise both successful and failure paths, and never expose an API key or endpoint URL.
