Slingshot Migrate rehearses the staked-XCN path from Ethereum Sepolia to Onyx Testnet. Open the app and choose Migrate. The page title is Migrate Staked XCN.
This is a test of the flow. Sepolia XCN and the XCN you receive on Onyx Testnet have no Mainnet value. You need Sepolia ETH for the Ethereum transactions and test XCN from the Faucet for anything you sign on Onyx.
What the page does
The page reads staked test XCN for the connected wallet on Sepolia. One start action then runs the steps and shows progress:
- Approve the Sepolia staking or token allowance when the current allowance is short.
- Withdraw or unstake that Sepolia position.
- Bridge the available test XCN to Onyx Testnet.
- Optionally stake it on Onyx when Stake on Onyx is on.
Each wallet prompt is its own signature. Read the chain, contract, amount, and allowance before you approve it. Switch networks when the page asks. A prompt on the wrong chain is the point to stop and switch, then continue the same migration.
Leave the page open while it waits for receipts and refreshes balances. The empty state No Staked XCN on Ethereum to migrate means this wallet has no Sepolia staked balance for the test contract.
If auto-stake does not finish
Stake on Onyx is optional. The bridge delivery can complete and the staking leg can still fail. In that case the test XCN remains in the wallet on Onyx Testnet, and the page records the staking error. Stake it afterward from Yield.
Confirm the finished balance on Onyx Testnet. A successful Sepolia transaction does not by itself mean the Onyx balance, or an stXCN balance, has arrived.
Bridge health and the amount the lane will accept are live. Read the quote on the confirmation screen. The app refuses an amount that lane will not take. The Bridge page is the place to inspect a Sepolia ETH or XCN transfer that you start outside this migration.
