Cross‑chain SDKs
Also known as: multichain SDK, interoperable SDK
Software development kits enabling blockchain interoperability via cross‑chain functionality.
Cross‑chain SDKs are programming libraries and tools that allow developers to build applications capable of transferring tokens, data, or messages across different blockchain networks seamlessly. They abstract cross-chain protocols, messaging layers, and bridging logic, enabling dApps to interact with Ethereum, Bitcoin, Polygon, and other chains through a unified API. These SDKs support secure asset bridging, multi-chain wallets, and composability across DeFi ecosystems.
