Smart Wallets by Crossmint
Smart contract wallets for fintechs, enterprises, AI agents. Built on smart contracts (ERC-4337 on EVM, Squads protocol on Solana), with dual-key architecture for agent autonomy, gasless transactions, cross-chain support across EVM, Solana, and Stellar.
Overzicht
Crossmint Smart Wallets are programmable smart contract wallets built for fintechs, enterprises, and AI agent platforms. On EVM chains, they are implemented using ERC-4337 (account abstraction). On Solana, they use the Squads protocol. Stellar is also supported. This smart contract architecture enables programmable security rules, gasless transactions (gas fees abstracted and billed in fiat), and modular signer management, all enforced at the contract level rather than relying on external key management alone.
A key differentiator is Crossmint's dual-key architecture, purpose-built for AI agent use cases: one key is held by the owner (user or company), and a second key is issued to the agent and sealed inside a Trusted Execution Environment (TEE). This allows agents to autonomously execute transactions within programmable spending controls, while the owner retains ultimate oversight and recovery capabilities. The architecture supports both stablecoin and card network payment rails, so agents can optimize payment selection based on speed, cost, and merchant acceptance.
Crossmint Smart Wallets integrate directly with the rest of the Crossmint platform, including stablecoin orchestration, on/offramps, and tokenization, providing a single infrastructure stack for wallets and payments across 50+ chains.
Het probleem
AI agents and enterprise applications need wallets that can autonomously transact across chains while maintaining human oversight. Traditional wallets lack programmable spending controls, agent-specific key isolation, and the ability to operate across stablecoin and card payment rails simultaneously.
