Exchange in 3 steps
-
Choose how much ARB to send and enter your Ondo address on ERC-20 on Ethereum.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer ARB to the address on your order — after confirmations, ONDO is sent to your wallet automatically.
What do you need to know?
- Arbitrum confirmations are usually fast — often within a minute.
- Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
- Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
- ONDO not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB on Arbitrum One
Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.
Leave enough ETH on Arbitrum for gas on top of the swap amount when required.
Ondo on Ethereum
Always match ONDO on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Receiving ONDO
Your wallet must be on ERC-20 on Ethereum.
Allow a few minutes after the order shows sent before opening support.

Frequently asked questions
Do I need KYC to swap ARB to ONDO?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Arbitrum to Ondo swaps.
How long does ARB to ONDO take?
Most swaps finish in 1–5 minutes. Timing depends on Arbitrum One and ERC-20 on Ethereum confirmations and current network load.
Is ARB to ONDO non-custodial?
Yes. You send ARB from your wallet and receive ONDO directly to the address you provide — SendSwap never holds your keys.
What if I send ARB on the wrong network?
Always match the network on your order page (Arbitrum One for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
