Everything, without a custodian
A custodial app’s features. Self-custody’s guarantees.
Earn, pay, protect and account for your money, every feature is an application of the same prepare-on-server, sign-on-device split.
The non-custodial guarantee
We built it so we cannot touch your money.
Self-custody is not a marketing line here, it is the architecture. Here’s exactly how it holds, even for automation like recurring autopay.
Read the security modelKeys never leave your device
Your seed phrase and passphrase are generated on-device and stored only in the OS keychain (Face ID / biometric gated, device-only, never cloud-backed). The backend stores public data, addresses and extended public keys, never a secret.
Prepare → sign → relay
Our servers only prepare unsigned transaction context and relay what your device signs. Signing happens on your phone, in an isolated crypto layer that is physically forbidden from touching the network or storage.
Allowances, not custody
Recurring payments and streams run on a revocable on-chain allowance you sign once, not an escrow. You can revoke at any time. Automated actions are scoped to withdraw-to-you-only and capped by time and amount.
Defense in depth
Recipient risk-screening, an anti-swap broadcast firewall, bank-grade spending guardrails, a one-tap freeze, clear-signing, an address-poisoning guard, and quarantine of unverified scam tokens mean you always see and control exactly what you approve, and only genuine funds ever count as yours.

Frequently asked
Yes, fully. Your seed phrase and private keys are generated and stored only on your device, in the OS keychain, and never reach our servers. The backend only ever sees public data like addresses and extended public keys. We prepare unsigned transactions and relay what your device signs; we can never move your funds.
SpendTheBits is architected so that your safety never depends on trusting us. Your private keys and recovery phrase are generated and stored only on your device, inside the operating system's hardware-backed keychain and gated behind biometric authentication, and they never reach our servers. Transaction signing runs in an isolated on-device layer that is forbidden from touching the network or storage. Every payment is screened for recipient risk and protected by an anti-swap broadcast firewall and an address-poisoning guard, while unverified scam tokens are quarantined so they can never masquerade as real funds. Because the wallet is fully non-custodial, no employee, attacker, or third party can move your assets.
Centralized exchanges and custodial apps hold your private keys, which means they can freeze your account, pause withdrawals, or lose your funds if the company fails. SpendTheBits is fully non-custodial: you alone hold the keys, on your own device, so your crypto cannot be frozen or seized and it remains yours even if our company disappears. Unlike a bare hardware or browser wallet, SpendTheBits also delivers exchange-grade features, including recurring payments, money streaming, cross-chain bridging, crypto gift cards, and an AI copilot, without ever taking custody. You get the convenience of a custodial super app with the ownership guarantees of genuine self-custody.
Your funds live on-chain, controlled by keys only you hold. Because nothing custodial sits between you and the blockchain, you can restore your seed phrase into any compatible wallet and keep full access, independent of us.
They use a revocable on-chain allowance (an EIP-2612 permit) that you sign once. It caps the maximum that can ever move and you can revoke it at any time. It is an allowance, not an escrow, your funds stay in your own wallet until each transfer happens.
Take back custody. Keep the convenience.
