Your first cross-chain transfer, step by step

Decide what you want to end up with. Real SOL on Solana? USDC on Base? Bitcoin exposure on Ethereum? That choice decides the route. If you want a different coin, a cross-chain swap is usually simplest. If you are moving USDC, look for a route that uses Circle's CCTP.

Then set up the destination wallet first. You need a wallet that supports the new network: Phantom for Solana, MetaMask or Rabby for Ethereum and its layer 2 networks, a Bitcoin wallet for BTC. Write down its recovery phrase on paper and store it safely.

Open a well-known app for your route. For Bitcoin to Solana, that might be Chainflip, THORChain or NEAR Intents. For Ethereum to Arbitrum, Across or an aggregator. Type in your amount.

Look at three things before you click anything.

On a route you have never used, send a small amount first. Pick something you would not mind losing but large enough to cover fees, often $20 to $50.

Yes, you pay fees twice. That is the price of finding a mistake with $30 instead of $3,000. Once the test arrives and you can see it in your wallet, send the rest the same way.

Check that the test arrived as the token you expected. Look at the token name and contract in your wallet, not just the ticker. If you received a wrapped version you did not want, it is far easier to sort out with a small amount.

Most lost transfers come from small input mistakes, not hacks.

Every network needs its own coin for fees. If you receive USDC on Solana with no SOL, you cannot move it. Turn on the gas on destination option if the app offers it, or send a little of the native coin to the new wallet first.

Also leave some of the source chain's coin behind. If something needs a second transaction, such as claiming a refund, you will need it.

Most apps show a progress page. Save that link and your transaction ID. You can also look up the transaction on the source chain explorer, such as mempool.space for Bitcoin or Etherscan for Ethereum.

If it is slow, check whether the first transaction is still waiting for confirmations. A Bitcoin transaction with a low fee can sit for a while. That is normal and needs no action.

If it is confirmed on the source chain but nothing arrived, wait for the time the app quoted, then contact support through the official site only. Give them the transaction ID. Never share your recovery phrase. Anyone who asks for it, including someone claiming to be support, is trying to steal from you.
