According to online reports, Brazil's well-known exchange B3 opened trading in Ethereum and Solana futures contracts today. In addition, B3 has also adjusted existing bitcoin futures contracts to reduce costs to attract domestic retail investors. These alternative currency contracts are mainly open to international customers. Two months ago, B3 attracted much attention because it became the world's first exchange to launch an XRP ETF. This progress is due to an improved regulatory environment in Brazil, which is committed to becoming a cryptocurrency hub. Today, B3 further consolidated Brazil's position in the industry by launching new futures contracts based on Solana and Ethereum.
