Non-custodial wallet — A non-custodial wallet is a cryptocurrency wallet whose private keys are generated and stored on the user's device — never on the provider's servers — meaning the provider cannot move, freeze, or seize the user's crypto.
"Not your keys, not your coins" is the shorthand. With a non-custodial wallet you (and only you) hold the private key material that authorises on-chain transactions.
The standard derivation path is BIP-39 (seed phrase) → BIP-32 (hierarchical deterministic key tree) → coin-specific derivation paths (BIP-44). The seed phrase is generated on-device using a CSPRNG and is never transmitted.
The trade-off is recoverability: lose the seed and the funds are unrecoverable. Custodial providers (Coinbase, Cash App, Robinhood) keep your keys server-side and can reset access; non-custodial wallets cannot.
Kronos's crypto wallet is fully non-custodial. The seed is generated on-device using @scure/bip39, the HD tree is derived with @scure/bip32, and signing happens locally with @noble/curves. KronosPay LLC has no copy of your private keys and cannot move your crypto. The licensed buy/sell exchange leg is brokered through partner Bridge but settlement is direct to your on-device wallet.
It eliminates provider-side seizure risk and exchange-failure risk (FTX, Celsius). It introduces user-side loss risk if you lose the seed.
No. The seed is generated on your device and never transmitted to KronosPay servers.
