Vitalik Buterin: AI’ll become the new UI and traditional on-chain applications may no longer exist in 2 years

Today Ethereum co-founder said at OKX NOW in Singapore that AI will become the new user interface in more and more scenarios.

He shared how a local AI agent wrote a script to update his ENS hash in about five minutes, and said performing complex blockchain operations without a traditional UI will become normal.

This could reduce security risks associated with traditional frontends, while introducing new challenges such as prompt injection, AI safety, and whether agents correctly understand onchain operations.

Also he said that over the next two years, Ethereum transaction costs are expected to fall further, privacy capabilities will improve, and the integration of AI with on-chain applications will accelerate.

He said future on-chain interactions may increasingly be handled by bots, while traditional applications could become less prominent, with AI directly interpreting on-chain offers and filtering transactions on users’ behalf.
