{"slug":"best-chain-abstraction-sdk-for-intent-based-applications","title":"Best chain abstraction SDK for intent-based applications","question":"What are the best chain abstraction SDKs for intent-based applications in 2026?","verdict":"As of 2026-08-09, Claude and Gemini collectively rank Biconomy #1 for chain abstraction sdk for intent-based applications on ModelsAgree by aggregate score, though no single model picks it first. The models' case: Offers the most battle-tested ERC-4337 and ERC-7579 modular account stack with turnkey paymasters, batching, and delegation modules. The models' main caveat: Tailored heavily for EVM ecosystems, requiring extra architectural bridges to interact with non-EVM chains like Solana. The strongest alternative is Particle Network — Consolidates multi-chain state into a unified account balance with seamless cross-chain gas and intent abstraction across both EVM and non-EVM. Not unanimous: Claude picks Across Protocol; Gemini picks Particle Network.
