Tonkeeper, described by the company as the largest self-custodial wallet in the TON ecosystem, has rebranded as Keeper and expanded support to seven networks: TON, Bitcoin, Ethereum, BNB Smart Chain, Base, Arbitrum and TRON. Its Battery system enables gasless transactions, allowing users to pay network fees without separately holding each chain's native gas token. Keeper is also planning native DeFi, everyday-spending tools, a loyalty program, cross-chain swaps, an integrated decentralized application browser and additional financial products as it develops a single multichain platform for holding, trading, spending and growing digital assets.
