How to test an XMR bridge transfer with ZeroFi

To test an XMR bridge transfer with ZeroFi, send a small amount of Monero to the bridge and check that the matching zXMR arrives on Ethereum’s Sepolia testnet. The two networks play different roles: XMR moves on Monero mainnet, while zXMR is an Ethereum token on Sepolia. The bridge’s validator nodes coordinate the deposit and the token mint. A testnet on one side does not make the XMR on the other side test money.

The deposit address connects the two steps. After Monero confirms the transfer, the bridge processes the deposit and issues zXMR to the connected Sepolia wallet. The return trip reverses that sequence: zXMR is redeemed through the bridge, and native XMR is sent to a Monero address. The fuller zerofi explainer covers the design behind those moving parts.

What do you need before testing an XMR transfer?

You need a Monero wallet with a small amount of real XMR, an Ethereum wallet set to Sepolia, and Sepolia ETH to pay Ethereum transaction fees. ZeroFi’s published test instructions recommend sending no more than 0.001 XMR. Treat that as a ceiling, not a target: begin with an amount you can afford to lose if a test transaction stalls or fails.

Before connecting, check that your Ethereum wallet is on Sepolia. Add zXMR as a custom token if the wallet does not display it automatically; the published token address is 0x0150614896eea01ce6Cb09C63B09d65fFf810A43. Confirm the address against ZeroFi’s current interface or instructions before adding it, since contract details can change.

How do you test the XMR-to-zXMR transfer?

Start by connecting the Sepolia wallet to the bridge interface and choosing the XMR-to-zXMR direction. The interface should provide a Monero deposit address for the transfer. Copy it carefully, then send a small amount from your Monero wallet. A bridge deposit address works like a one-use delivery address: it tells the bridge which incoming transfer to process.

Wait for the Monero transaction to confirm and for the bridge to process it. Then check the Sepolia wallet for zXMR. If the token balance is hidden, check the token contract and wallet address; also check the bridge interface for transaction status. Do not send a second deposit just because the first is taking time. A delayed display and a failed transfer are different problems.

How do you check the return transfer?

To test redemption, choose zXMR-to-XMR, enter the Monero address you control, and redeem only a small part of the zXMR balance. The bridge must process the token redemption on Sepolia and send XMR on Monero mainnet. Check the Ethereum transaction first, then verify that the XMR reaches the specified Monero wallet.

• Keep the Monero deposit and Sepolia wallet addresses available so you can match the two sides.
• Record each transaction identifier and whether the bridge reports it as pending or complete.
• Do not assume a displayed zXMR balance proves you can redeem; test the return path separately.

A useful test checks both directions and leaves a record of what happened at each step. It can show that your wallets, network selection and the bridge flow work for that transfer. It cannot establish that every later transaction will succeed, or remove the bridge’s operational and validator risks. The practical lesson is simple: because this test uses real XMR, test with a very small amount and verify the return before sending more.
