 At Nevermined, we see a future in which dominant consumers are AI agents. We also believe the primary chokepoint to AI advancement will be each AI Agent's ability to access and transact on the services and data they require to optimize their output. There are 2 bottlenecks that significantly impede the current progress of AI agents:
 
 - AI Agents won’t have a bank account for numerous reasons, including their inability to pass required, traditional KYC. Instead, they will have wallets on-chain.
