TON Space
Self-custody mode inside the Telegram Wallet: the user holds the seed phrase and the keys never leave the device. Launched by The Open Platform in 2024.
Aliases: ton space, wallet self-custody mode
TON Space is the built-in self-custody mode inside the Telegram Wallet bot (@wallet). Launched by The Open Platform in 2024 as a counterpart to the custodial mode of the same bot: the user holds the seed phrase, and Telegram has no access to keys.
How it differs from the custodial Wallet
- Custodial Wallet — keys are held by The Open Platform; support-assisted recovery; KYC for limits.
- TON Space — keys live only with the user; recovery is seed-only; no KYC.
Architecture
- Standard 24-word mnemonic, BIP39-compatible.
- Under the hood — a standard TON wallet contract (v4 or v5), same family Tonkeeper uses.
- Supports TON Connect for dApp connections.
Limitations
- Not available in all jurisdictions; the supported region list changes.
- No hardware-wallet (Ledger) flow, unlike Tonkeeper.
- No support-assisted recovery — losing the seed means losing the funds.
