Learn how to add, send, and withdraw Bitcoin on Ouro.
Last updated December 4, 2025
6 minute readThis guide covers everything you need to know about using Bitcoin on Ouro, from funding your wallet to withdrawing to external addresses.
Think of Bitcoin on Ouro the way you might buy credits on a platform like OpenAI or Anthropic, except these credits work anywhere that accepts Bitcoin. They never expire, can appreciate over time, and remain yours: move them to another wallet or exchange, convert them to dollars, or spend them on any compatible platform.
No identity verification is needed and no bank account is required. That makes Bitcoin a natural fit for AI agents and programmatic workflows, as well as anyone who prefers global, self-custodial money.
Ouro also supports USD payments powered by Stripe. Pay with a card, withdraw to your bank. Each monetized asset uses one currency, so you may want both wallets funded.
New to Bitcoin? Don't worry, this guide keeps things simple. You don't need to understand blockchain technology to use Bitcoin on Ouro.

When you create an Ouro account, a wallet is automatically created for you. To fund it:
Best for deposits from exchanges like Coinbase, Kraken, or Robinhood.
Only send Bitcoin to your deposit address. Sending other cryptocurrencies will result in permanent loss of funds.
Network fees are deducted from your deposit. Funds appear in your wallet after 3 confirmations, and there's no minimum deposit amount.
Best for transfers from other Spark-compatible wallets.
Spark transfers have zero fees, settle instantly, and have no minimum amount.
If you don't have Bitcoin yet:
Support creators or tip other users directly on the platform.
Transfers between Ouro users are instant and free. They use Spark L2 under the hood.
Send Bitcoin to any wallet outside of Ouro.
Spark Transfer (for L2 wallets):
spark1p or sparkrt1)L1 Exit (for main Bitcoin network):
bc1p, bc1q, 1, or 3)You have two options for withdrawing Bitcoin from Ouro.
Best for fast, free withdrawals to Spark-compatible wallets.
Spark withdrawals have no minimum, no fees, and settle instantly.
Best for withdrawing to exchanges, hardware wallets, or standard Bitcoin addresses.
| Speed | Time | Fee | Best for |
|---|---|---|---|
| Slow | ~12-24 hours | Lowest | Non-urgent withdrawals |
| Medium | ~4-6 hours | Moderate | Most use cases |
| Fast | ~1-2 hours | Highest | Urgent withdrawals |
Withdrawals are irreversible. Double-check the destination address before confirming. Network fees are deducted from your withdrawal amount.
Creators can price files, datasets, posts, or API routes in sats. To purchase:
If you don't have enough balance, you'll be prompted to add more Bitcoin to your wallet.
Use Spark (L2) whenever you can since it's instant and free. If you need to withdraw to L1, try to batch smaller amounts together because L1 exits have a 10,000 sat minimum and network fees that vary with congestion. Always double-check destination addresses before sending since Bitcoin transactions are irreversible. And keep some balance in your wallet so you're ready to pay for content and support creators without topping up every time.
