It wraps Curvance contract deployments, ABIs, market metadata, token models, protocol readers, zappers, leverage helpers, and external integrations behind a developer-friendly ethers v6 interface. The SDK is designed to make protocol reads cheap and ergonomic. setupChain() bulk-loads market and protocol state up front, then exposes cached Market, CToken, BorrowableCToken, ProtocolReader, and DEX aggregation helpers for common workflows like market discovery, balance checks, position health, deposits, borrowing, repayment, zaps, and leverage planning.
