Phantom API — Mantle Transaction History

Use this endpoint when you need historical transaction data specifically on the Mantle L2 network, with flexible filtering by address, block range, category, and sort order. Prefer this over general Ethereum history endpoints when the target chain is Mantle, and over block explorers when you need structured, paginated, programmatic access rather than a human-readable UI.

• Invalid address format returns a 400 error
• Unknown pageKey causes pagination failure or empty result
• Block range with toBlock earlier than fromBlock returns error or empty set
• Payment not attached or insufficient USDC triggers 402 Payment Required
• Network congestion or node unavailability may cause timeout
• Invalid category enum values result in bad request error
