Tonkeeper Becomes Keeper as Seven-Network Wallet Adds Bitcoin and Ethereum

Tonkeeper is no longer positioning itself as a wallet built mainly for one blockchain.

The self-custody app has rebranded as Keeper and added support for Bitcoin, Ethereum, TRON, BNB Chain, Arbitrum and Base alongside TON. That gives the mobile wallet seven supported networks and puts the two largest crypto assets at the center of its expansion.

The name change comes with a larger product shift. Keeper is trying to turn a wallet closely associated with the TON ecosystem into a broader tool that people can use without handing their keys to an exchange.

The official Keeper site says the multichain experience is available on mobile first, with its other platforms set to follow. It lists TON, TRON, Ethereum, Bitcoin, Arbitrum, Base and BNB Chain, while continuing to describe the product as self-custodial: users’ keys stay on their own devices.

Keeper announced the change directly on X and said the app now holds assets across the newly supported networks while preserving the TON features that built its original audience.

Existing Tonkeeper users are not being told to move their TON assets into an unrelated custodial account. The product’s pitch is that the familiar TON wallet remains in place while a separate multichain setup lets users activate the additional networks.

That distinction matters because blockchain accounts do not all use the same underlying key standards. Keeper says TON’s key-generation approach is not compatible with the BIP-39 and BIP-44 standards commonly used across Bitcoin and EVM wallets.

In practice, users should read the migration prompts carefully, back up every recovery phrase offline and never assume one phrase controls an account unless the app explicitly confirms it.

The Block reports that the wallet’s parent company, The Open Platform, now oversees operations and says the product has more than 77 million registered users. That figure comes from the company rather than an independent audit, but it helps explain why this is more than a cosmetic rebrand: a large TON-focused user base is being invited into a wider set of crypto networks.

The rollout also gives Keeper a much broader competitive set. Bitcoin and Ethereum support puts it alongside established multichain wallets, while its TON roots remain a point of differentiation for users who already rely on TON staking, tokens, NFTs and decentralized applications.

TRON is another practical piece of the strategy, especially for people who move USDT. TRON founder Justin Sun highlighted the network’s addition to Keeper shortly after the announcement.

Keeper’s Battery feature is designed to reduce one of the most annoying parts of moving tokens: needing a second asset solely to pay a network fee. The official site says Battery currently works on TON and TRON, where users can fund it with crypto or a card.

Support for additional networks is promised, but users should not read the seven-network announcement as proof that Battery is already live everywhere.

The same caution applies to the wider roadmap. Decrypt describes plans for more cross-chain swaps, decentralized-finance tools, spending products and broader app access.

Those plans may make the wallet more useful over time, but the clean line today is simpler: seven networks are listed, multichain support is mobile-first, and some supporting features remain limited or forthcoming.

For users, the expansion creates convenience without eliminating wallet risk. Self-custody removes the exchange from the key-holding relationship, but it also puts recovery, phishing defense and transaction review in the user’s hands. Anyone activating the new networks should confirm they are using the official Keeper app, store recovery material offline, verify destination addresses and test unfamiliar transfers with a small amount first.

The rebrand is ultimately a bet that crypto users want fewer wallet silos. Keeper is keeping its TON foundation while reaching for Bitcoin, Ethereum and several large smart-contract ecosystems. If the product can make those networks feel coherent without blurring their security differences, the change will be more meaningful than the new name.
