TON ecosystem wallet Tonkeeper has rebranded as Keeper and expanded network support from TON to seven chains, including Bitcoin, Ethereum, TRON, BNB Smart Chain, Arbitrum and Base. The wallet has more than 77 million registered users. The Open Platform founder and CEO Andrew Rogozov said the goal is to build the default self-custody wallet for a multichain world. The platform took over operations last month and plans to add native DeFi services, cross-chain swaps and perpetual futures trading.
