Check the status of a pending Nest vault withdrawal request on the AtomicQueue. Reads getUserAtomicRequest and checks if offerAmount == 0 (fulfilled) or still pending. Ideal for: withdrawal status polling, rebalancing retry loops, position monitoring.

Look up a wallet's balance for a specific token. Faster than fetching all balances when you only need one. Use a contract address for ERC-20 tokens or 'native' for ETH/MATIC. Returns balance and USD value.
