Self-sovereign artificial intelligence agents are reshaping digital autonomy by giving individuals full control over their identity, data, and decision-making through decentralized identity and blockchain.
Natural language transactions and self-control
The rise of self-sovereign artificial intelligence (AI) agents represents a major shift in digital autonomy. Rather than relying on centralized cloud platforms, individuals have full ownership and control of agents that manage their decision logic and personal data. Using decentralized identity (DID) and private data storage, these agents keep users’ information and policies private. By combining AI with blockchain, they can independently conduct financial transactions, manage sensitive documents and communicate with global networks without corporate intermediaries.
Launched on March 30 at the EthCC in Cannes, Coinfello is one of the first self-sovereign AI agents built to automate on-chain actions. According to a press release, the platform offers a conversational interface that allows users to research, execute and automate transactions using natural language while maintaining custody of their wallets and private keys.
To address coordination in a decentralized environment without a central “off” switch, Jacob Cantele, co-founder and CEO of Coinfello, said agents are limited by strict, user-defined permissions. Agents operate only within permitted limits, and owners can revoke permissions or disable agents at any time, replacing corporate oversight with direct personal control.
As governments and businesses look to reduce dependence on foreign cloud providers, decentralized infrastructure offers a path to technological independence. Cantele emphasized that Trusted Execution Environments (TEEs) and confidential computing give users access to powerful hosted agents without giving third parties the power to censor transactions. While the product is aimed at private users and developers today, Cantele said he expects institutional adoption in the future.
Bridging the DeFi usability gap
Participation in decentralized finance (DeFi) remains limited by complex instruments and the fear of irreversible mistakes.
“Today’s launch marks a shift from passive crypto ownership to active participation. By combining self-management with a natural language interface, we are enabling millions of users to interact with DeFi in a way that is both accessible and secure, without compromising control,” said Minchi Park, co-founder and COO.
By combining self-management with a natural language interface, Coinfello aims to make DeFi more accessible and secure without sacrificing control. Coinfello’s web app is now public after a private alpha and uses a delegation model focused on security. For example, macOS devices store private keys in the Secure Enclave, while displaying transactions in plain language for user consent. The app also integrates with Metamask and other EVM wallets and creates smart accounts for automation.
Coinfello also introduced “agent skills” so that remote AI agents can use the platform as an execution layer. These agents can request delegated permissions to stake, exchange, or send tokens within user-defined limits. This allows personal AI agents, such as Openclaw or Claude Code, to perform on-chain operations without the user handing over their private keys.
