In a first for Swiss banking, client-issued plain text instructions have been used to execute multi-step live transactions on a blockchain Mainnet. The Sygnum AI agent used these instructions and independently planned and prepared each step, reviewed the relevant smart contracts, and flagged potential transaction risks before presenting each transaction to the client for approval. Transactions are only signed through the client\u2019s self-custodial wallet on their own device, ensuring private keys do not leave client control at any time. Sygnum\u2019s AI agent can be used to execute multi-step on-chain transactions for stablecoin transfers, asset swaps, on-chain lending positions, token wrapping and liquidity provisioning.<\/p>\n\n\n\n
The pilot was built using a Model Context Protocol (MCP) server built in-house by the AI@Sygnum team using Anthropic’s Claude as the underlying AI model. MCP is a new open standard enabling AI and financial platforms to share context and data, streamlining transactions while maintaining client control and security safeguards. The MCP-based architecture is model- and asset-class agnostic, allowing the infrastructure to scale as the ecosystem develops.<\/p>\n\n\n\n
Connecting AI agents to wallets is foundational to where finance is heading. The next decade will see agents transacting, settling and interacting with markets on behalf of clients. The key challenge is doing this in a way that preserves \u2013 and even enhances \u2013 bank-grade consent, custody and trust. That is what we set out to solve, and what this pilot demonstrates: that a regulated Swiss bank can provide clients with the speed, convenience and accessibility of agent-driven execution, without ever giving up control of their assets.<\/p>\n\n\n\n
Unlike architectures where AI agents with their own wallets transact autonomously, Sygnum\u2019s approach enables clients to own, hold and fully control their own wallets and assets at all times<\/a>. This reflects a core principle of the AI@Sygnum program, where AI augments and enhances, but does not replace, human decision making<\/em> or trusted personal relationships. <\/em>This will benefit clients by enabling them to directly execute on-chain actions and access live market infrastructure, compose multi-step workflows without code and use their wallets natively.<\/p>\n\n\n\n This \u201chuman-in-the-loop\u201d design is central to Sygnum\u2019s integration of its agentic AI roadmap into all areas of the group\u2019s global operations. The four key pillars of Sygnum\u2019s organisational AI strategy are:<\/p>\n\n\n\n\n
