About Keeper
Keeper is a self-custodial wallet on TON, formerly Tonkeeper, with keys kept on the device and no email or identity collected. It uses the W5 contract standard to support gasless USDT transfers and batch operations, TON Connect 2.0 for dApp handshakes, and built-in swaps, staking, NFTs and on-chain subscription management; Battery lets users prepay fees with a stablecoin or a bank card instead of holding TON first.
Its place is the reference wallet and entry point for TON: most dApps that support TON Connect are tested against it, and Tonkeeper Pro targets multi-account and multisig treasury use with folders, batch transfers and on-chain two-factor confirmation. In 2026 it shortened the brand to Keeper and its mobile app began supporting TON, TRON, Ethereum, Bitcoin, Arbitrum, Base and BNB Chain, with cross-chain swaps that no longer need a separate bridge. The wallet expands what is being signed into a readable recipient and amount, and with hardware signing and multisig a large holder can use the phone purely as a confirmation device.
On 15 September 2026 Tonkeeper rebranded as Keeper, expanding from a single TON wallet to seven networks including TON, Bitcoin, Ethereum, TRON, BNB Chain, Arbitrum and Base, with about 77 million downloads to date. The point of seven chains is not the count but getting one key-management scheme to satisfy both UTXO and account models safely.
Because TON derives keys differently from the BIP-39/44 standard, the Keeper team built a wallet architecture that covers EVM chains and Bitcoin under one recovery phrase, with existing accounts and balances carried over untouched. Cross-chain swaps source liquidity from MoonPay rather than an external bridge, and Battery keeps paying network fees on TON and TRON so users need no native gas token. Users who migrated before 22 September received fee-free cross-chain swaps. Battery abstracts gas into an optional service, with the biggest effect on a new user's first transfer and sponsorship cost the trade-off.
Keeper plans to extend Battery to every supported network, build in DeFi, everyday spending and a dApp browser, and add perpetual futures within the next year. After seven chains, adding a network depends mainly on compatibility of key derivation and token standards. Hardware wallet and multisig support are also on the roadmap.
