Tonkeeper has rebranded as Keeper and expanded beyond its original TON focus. Its official website now lists Bitcoin, Ethereum, TRON, Arbitrum, Base and BNB Chain alongside TON, with multichain support arriving on mobile first.
The developer's App Store release notes say existing keys, recovery phrases, accounts and balances remain unchanged. Users can switch to a multichain wallet inside the app to enable the additional networks.
Network support and fee support differ
Keeper advertises cross-chain swaps and a browser for applications across its supported networks. Its Battery feature lets users fund fees without separately holding the network's gas token, but the website currently limits that feature to TON and TRON. More networks are planned.
That distinction matters when moving assets: support for a blockchain does not automatically mean every convenience feature works there.
For background on the fee model, gas sponsorship shifts who funds a transaction. Keeper's network-specific availability still needs to be checked before relying on that option.
