Ethereum co-founder Vitalik Buterin stated at the OKX NOW event in Singapore on October 6, 2026, that AI will become the new user interface in an increasing number of scenarios. He shared an example of how a local AI agent wrote a script to update its ENS hash in about five minutes, noting that performing complex blockchain operations without traditional UIs will become the norm. This is expected to reduce security risks associated with traditional frontends but also introduces new challenges such as prompt injection, AI security, and whether the agent correctly understands on-chain operations.
