According to Wu Shuo, Wu Shuo learned that according to Arkham monitoring, Ethereum co-founder Vitalik Buterin transferred 199.9 ETH to the multi-signature contract: 0xC3...b72f at 22:25 UTC+8 today, worth about 517,000 US dollars.

Through the analysis of the multi-signatures of the multi-signature contract, it is suspected that the donation was made by Vitalik Buterin to a project called ethOS (Ethereum Phone).

The multi-signatories of this multi-signature contract, stipe.eth, emusi.eth and berdi.eth, are members of the Ethereum Phone project team.
