Wu said that according to Bitcoin News, Renato Kiyotaka Uema, deputy director of the Financial System Regulation Department of the Central Bank of Brazil, stated at a public hearing that if certain conditions are met, the central bank may revoke its previous proposal to ban self-custody of stablecoins. The proposal originally required stablecoin transactions to be limited to regulated exchanges. Uema emphasized that if the market can provide technological solutions to enhance transaction transparency, the central bank will consider relaxing regulations. He stated: "This is a public consultation, and if there are suggestions that can reduce associated risks, the technology department will minimize interference with market flexibility as much as possible."
