CANDIDE

CANDIDE is wallet infrastructure built around ERC-4337 account abstraction, made of smart account contracts, a bundler and a paymaster. Smart accounts are adapted from Safe contracts and expose validation and execution methods to the entry point, splitting an operation into verification and execution; the Voltaire bundler collects user operations and submits them in batches, while the paymaster either sponsors gas or lets users pay fees in stablecoins. Accounts support passkey signatures, guardian recovery and synchronised configuration across chains.

For developers, AbstractionKit packages these capabilities into an SDK so apps can set spending limits, session keys and subscription rules, letting automated agents act within authorised bounds. The product also does cross-chain execution: one signature completes an action on Base, Arbitrum, Optimism and Polygon at once, verified through Merkle proofs rather than a bridge.
