OneBalance quotes enable cross-chain operations including asset transfers, swaps, and arbitrary contract interactions. They facilitate the core transaction lifecycle by providing cost estimates and execution plans.
Account Setup Required: Quotes require proper account configuration. See Account Models for setup instructions.
