Build Web3 Applications Without the Complexity
UTXOS is a full-stack Web3 infrastructure platform that provides self-custody wallets, transaction sponsorship, and fiat on-ramp services for Bitcoin, Cardano, and Spark. You handle the product; UTXOS handles the blockchain complexity.
Why is Web3 onboarding hard?
Onboarding users to Web3 remains a significant barrier to adoption:
- Seed phrases confuse and intimidate new users
- Gas fees require users to acquire crypto before they can interact
- Complex transactions create friction and abandonment
How does UTXOS solve this?
UTXOS eliminates these barriers with a complete infrastructure platform:
| Service | What It Does |
|---|---|
| Wallet as a Service | Create and manage wallets with social login, passkeys, and recovery. No seed phrases required. |
| Transaction Sponsorship | Pay gas fees on behalf of your users. Remove the crypto requirement entirely. |
| Fiat On-Ramp | Let users purchase crypto directly within your application. |

Frequently asked questions
What chains does UTXOS support?
UTXOS supports Bitcoin, Cardano, and Spark (Bitcoin Layer 2). All plans include multi-chain support.
Is UTXOS custodial?
No. UTXOS wallets are self-custody. Private keys are split using Shamir’s Secret Sharing and never exist as a complete entity on UTXOS servers. Users can export their keys at any time.
Do my users need to hold cryptocurrency?
Not with transaction sponsorship. You can pay network fees on behalf of your users, so they can interact with your application without owning any tokens.
How long does integration take?
You can enable a multi-chain wallet with three lines of code. Most developers complete a basic integration in under an hour.
UTXOS supports Bitcoin, Cardano, and Spark networks. Multi-chain support comes standard with all plans.
