Exchange in 3 steps
-
Choose how much OP to send and enter your Bitcoin address on Bitcoin mainnet.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer OP to the address on your order — after confirmations, BTC is sent to your wallet automatically.
What do you need to know?
- Optimism confirmations are usually fast — often within a minute.
- Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- BTC not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.

Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.
Leave enough ETH on Optimism for gas when moving OP or other tokens.
Bitcoin — the original digital asset
Since 2009, Bitcoin has been the benchmark cryptocurrency — deep liquidity, wide recognition, and the default on-ramp for cross-chain swaps.
When is my BTC spendable?
After your payout transaction receives the confirmations shown on the order page — typically one or more blocks depending on route.
Checking your BTC payout
- Open the order page and copy the payout transaction hash into a Bitcoin block explorer.
- Confirm the destination address matches your wallet exactly — including case and format.
- Most wallets show incoming BTC after one confirmation; some exchanges wait for more.

Frequently asked questions
Do I need KYC to swap OP to BTC?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Optimism to Bitcoin swaps.
How long does OP to BTC take?
Most swaps finish in 1–5 minutes. Timing depends on Optimism mainnet and Bitcoin mainnet confirmations and current network load.
Is OP to BTC non-custodial?
Yes. You send OP from your wallet and receive BTC directly to the address you provide — SendSwap never holds your keys.
What if I send OP on the wrong network?
Always match the network on your order page (Optimism mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
