Tonkeeper, the self-custodial wallet that grew up on The Open Network, has rebranded as Keeper and added support for six blockchains beyond TON: Bitcoin, Ethereum, Tron, BNB Smart Chain, Arbitrum and Base.
The company shared the change exclusively with The Block on Tuesday. Keeper claims more than 77 million registered accounts, which would make it one of the largest self-custodial wallets anywhere, and by far the biggest in the TON ecosystem, where Telegram’s crypto push drove adoption through mini-apps and payments integrations.
The rebrand follows an August management transition. The Open Platform (TOP), the TON ecosystem developer led by founder and CEO Andrew Rogozov, took operational control of the wallet. Co-founders Oleg Andreev and Oleg Illarionov remain shareholders. Rogozov framed the change in a statement: “Keeper is the next chapter: taking the simplicity we’re known for beyond TON and into the broader crypto economy.” He told KuCoin-syndicated coverage that the goal is to become the default self-custody wallet for a multichain world, letting users hold, trade and spend across any chain.
Why a TON wallet is leaving TON-only behind
The stated reason is user behavior. Keeper says many of its existing users now hold bitcoin, ether, stablecoins and assets on Ethereum-compatible layer-2 networks alongside their TON tokens. A wallet named after one chain stopped describing what its users actually do. Under the old setup, those users needed several applications to manage everything, and Keeper wants to collapse that into one app with a single address book.
The multichain push puts Keeper in direct competition with MetaMask and other established wallets. The difference is distribution. Keeper arrives with a user base most rivals spent years building, acquired largely through TON and Telegram-linked applications. The open question, which analysts have flagged since the announcement, is whether a base built through Telegram will adopt the wallet for activity on Bitcoin and Ethereum, chains with different user cultures and security expectations. Wallet switching is famously sticky in the other direction: MetaMask users rarely migrate, and TON natives may treat the new chains as a convenience rather than a home.
What ships now, what comes later
The existing Battery feature carries over. Battery covers transaction fees on behalf of users, so people can send USDT without holding TRX on Tron or TON for gas, and Keeper says it saves up to 50% on Tron transfer fees. The company plans to extend Battery across all seven supported networks, removing one of the classic multichain friction points where users juggle gas tokens.
Planned for the coming year, with no specific launch dates disclosed: cross-chain swaps without bridges, DeFi services, spending tools, a decentralized application browser, a loyalty program and perpetual futures trading. The wallet also operates on iOS, Android, macOS, web and a browser extension, so the expansion is not mobile-only.
| Network | Status at rebrand |
|---|---|
| TON | Original chain, retained |
| Bitcoin | New support |
| Ethereum | New support |
| Tron | New support |
| BNB Smart Chain | New support |
| Arbitrum | New support |
| Base | New support |
Context: wallets are becoming financial platforms
The move fits a broader pattern. Wallets increasingly embed swaps, staking, lending and derivatives, competing with centralized exchanges for the same activity. The perps plan is the clearest signal: Keeper intends to offer leveraged trading inside a self-custodial app, a category that exchanges dominate today. If it ships, Keeper would join a short list of wallets trying to make on-chain derivatives feel like an exchange interface.
TON itself has been through a difficult stretch. Toncoin, now rebranded as GRAM, trades around $1.32, down sharply from its 2024 highs near $8. The wallet’s pivot can be read as a hedge on that decline: if TON activity stays depressed, Keeper’s economics no longer depend on it. TOP’s control also aligns the wallet with the broader TON infrastructure push, including ecosystem funding and developer tools, rather than leaving it as an independent single-chain utility. TOP’s stake means the wallet’s success now feeds back into the ecosystem it came from, whether or not users ever touch TON again.
The competitive math
MetaMask claims over 30 million monthly active users, and its browser-extension dominance came from being the default in Ethereum’s early years. Keeper’s 77 million registered accounts are a different kind of number: registered, not necessarily active, and concentrated in a Telegram-linked demographic. Still, the distribution is real, and the multichain expansion gives existing users a single app for assets they previously managed across four or five separate applications.
The privacy posture is also part of the pitch. Keeper markets itself as requiring no email, no KYC and no custodian, connecting directly to each network with keys stored on the user’s device. That positioning matters as regulators tighten self-custody rules in several jurisdictions, and it distinguishes Keeper from exchange-linked wallets that require identity verification. Whether that posture survives the planned spending tools and derivatives features, which typically bring compliance obligations, is one of the quieter tensions in the roadmap.
For users, the practical change is immediate. Existing Tonkeeper users keep their keys and addresses. The app gains support for six more chains, and the fee-covering Battery extends with it. The roadmap items, swaps, DeFi and perps, arrive later and will determine whether the rebrand is cosmetic or structural. The wallet’s own framing is confident, but the market will judge it on whether bitcoin and ether holders actually show up in the app.
