Keeper steps beyond TON: Tonkeeper rebrands as a multichain self-custody wallet with Bitcoin, Ethereum, and Tron

Keeper isn’t just a new name for Tonkeeper—it’s a bid to own the multichain wallet experience. The self-custodial app, long synonymous with The Open Network (TON), now supports seven blockchains: TON, Bitcoin, Ethereum, Tron, BNB Smart Chain, Arbitrum, and Base. The move acknowledges what many power users already do: manage BTC, ETH, USDT on Tron, and L2 assets across multiple apps while keeping TON at the core.

The hinge here is not the chain list; it’s whether Keeper can turn multichain from a feature into muscle memory. That’s where its “Battery” fee abstraction comes in. By letting users pay transaction costs without holding each network’s native token, Keeper attacks the single worst point of friction in multichain self-custody—constantly hunting for gas. The team plans to extend Battery to every supported network within a year, though it hasn’t disclosed which chains are covered at launch.

If Battery works reliably across EVM, Tron, and even Bitcoin-flavored workflows, usage patterns change. Swaps, transfers, and on-chain actions stop being gated by a missing dust balance and start becoming routine. Under the hood, this demands careful relayer economics, anti-spam controls, and safeguards against centralized chokepoints. In practice, fee abstraction systems can quietly introduce policy risk (what gets relayed, when, and at what price), so execution quality will determine whether Keeper preserves the spirit of self-custody while smoothing the edges.

Positioning-wise, Keeper is leaning into a Telegram-first world. Telegram made TON the exclusive chain for crypto-enabled mini apps in January 2025 and later tightened its involvement in network direction. The Open Platform (TOP)—which backs Keeper and builds other TON products—raised $28.5 million at a $1 billion valuation in 2025, and it also develops the self-custodial TON Wallet inside Telegram. The broader TON financial stack has been building out as well: lower-barrier staking arrived via Telegram in June 2025, and Libre with the TON Foundation launched a $500 million tokenized Telegram bond fund that April. In that context, Keeper’s expansion reads as a funnel widener: keep TON-native strength while capturing the flows users already have elsewhere.

Competition is not standing still. MyTonWallet rebranded to “My Wallet” in June after extending from TON to 11 networks, and TON DEX STON.fi launched cross-chain swaps in July to connect TON with Tron and several EVM chains. Wallets increasingly look like “intent routers” with built-in liquidity, bridging, and spending tools. Keeper’s roadmap fits that script: cross-chain swaps, a DeFi suite, a dapp browser, loyalty features, spending tools, and even perpetual futures—though no launch dates were provided.

The derivative angle is powerful but delicate. Embedding perps into a primary wallet can boost engagement, yet it also amplifies risk perception, behavioral bias, and potential compliance exposure across jurisdictions. Sophisticated guardrails, transparent risk disclosures, and easy off-ramps matter if the goal is daily usage, not just thrill-seeking. Users who come for simple transfers and stablecoin spending tend to punish products that blur lines between banking-like utility and leverage without clear separation.

Technically, covering such a heterogeneous set—Bitcoin UTXO logic, EVM L2s, Tron’s account model—requires sturdy abstraction layers, meticulous key management, and fail-safe signing flows. Small UX leaks (e.g., unpredictable fee estimates, stale RPCs, or signature prompts that vary wildly by chain) quickly erode trust. This is the quiet moat: consistent, low-latency performance across chains that feels the same every time, even when the networks are not.

User behavior already validated the thesis. Keeper’s team says many of its users outgrew a single-chain setup and juggled four or five apps to manage holdings across BTC, ETH, Tron USDT, and L2s—while still considering Tonkeeper their anchor. Renaming to Keeper acknowledges that reality and invites a broader audience to discover TON-native features without forcing chain loyalty.

The pattern is clear: wallets are becoming operating systems for on-chain life. If Keeper nails fee abstraction, intentful cross-chain swaps, and a clean separation between everyday payments and higher-risk DeFi/perps, it can convert multichain from novelty into habit—especially inside Telegram’s vast distribution. Execution, not the chain count, will decide who owns the home screen.
