Wormhole bridge moves tokens between blockchains in seven steps, from checking the route to confirming receipt. The chains coordinate through signed messages: records that tell the receiving chain what happened.
Say you hold SOL on Solana and want to use it on Ethereum. Before sending, you need to know which token will arrive. Moving SOL across does not turn it into ETH.
What Moves and What Arrives
Wormhole connects Solana, Ethereum, Arbitrum, and other blockchains. A connected pair of chains does not mean every token can move between them. Check the exact token and transfer method first.
- Wrapped Token Transfers (WTT) lock the original token and issue a matching wrapped token on the other chain. A wrapped token represents the original, but has its own contract address.
- Native Token Transfers (NTT) let a token’s creator make it available across chains. Depending on its setup, tokens are burned and issued again, or locked and released.
- Messages carry instructions between blockchain apps. A message can trigger an action, but it is not a token in your wallet.
For a first transfer, the key question is what you will receive. If an app requires a particular token contract, a different wrapped version may not work there.
Seven Steps to Send a Token
- Choose the route. Identify the chain holding your token, the destination chain, and the exact asset. Check that this combination supports a transfer. For example, sending SOL from Solana to Ethereum may give you wrapped SOL on Ethereum, rather than ETH.
- Prepare your wallets. Use a wallet that can sign on the source chain and an address that can receive on the destination chain. Keep some of each chain’s gas token for fees: SOL on Solana and ETH on Ethereum. Gas pays for a recorded blockchain action, called a transaction.
- Set up the transfer. Enter the two chains, token, amount, and receiving address. To start that cross-chain move, use Wormhole bridge for the chosen asset and destination. The Wormhole crypto bridge coordinates the move; your wallet authorizes your transaction.
- Review the result and cost. Check the full receiving address and the token expected on the destination chain. Review the source gas, any delivery charge, and any destination gas you must pay yourself. Solana gas can be a fraction of a cent; Ethereum gas can cost several dollars or more when busy.
- Confirm the source-chain transactions. Your wallet may first ask permission for a token contract to spend the amount you chose. It then asks you to confirm the transfer. Read both requests before signing, and use an exact spending amount if your wallet offers that choice.
- Complete the destination transfer. Wait for the source transaction to settle and for Wormhole’s signed message to become available. A relayer, a service that delivers the message, may finish the transfer for you. Otherwise, you must submit the destination transaction yourself and pay its gas.
- Verify what arrived. Check the destination transaction and your wallet balance. If the token is missing from the wallet view, check its contract address before adding it. A completed source transaction alone does not prove that the destination step has finished.
How the Transfer Reaches the Other Chain
A Wormhole bridge transfer reaches the destination through a signed message and a second chain’s contract. With WTT, the source contract locks an original token or burns a wrapped one. Wormhole Core publishes a message describing that action.
Guardians, the network’s observers, check the source event. At least 13 of 19 sign a proof called a VAA, short for Verified Action Approval. Once that proof reaches the destination, its contract checks the signatures and issues the wrapped token or releases the original. That final submission is why a transfer can still need attention after you send it.
Common Questions Before You Send
Why would I use it to move tokens?
Use it when you hold a token on one chain but need that asset on another. You might, for example, hold SOL on Solana and need its Ethereum-side representation for an app there. Check that the receiving app accepts the token you will get. Bridging a token does not exchange it for a different asset.
Is it safe to use?
Wormhole checks transfers through Guardian signatures and contracts on both chains, but no bridge removes all risk. A mistaken address, a fake token, or a flaw in a contract can still cause a loss. Verify the destination token and address, review wallet requests, and consider a small first transfer when using an unfamiliar route.
Can I bridge tokens with Wormhole from Solana to Ethereum?
Yes, when the particular token has a supported route between those chains. The result depends on its transfer method: a Solana token may arrive as a wrapped token on Ethereum. You may also need ETH to finish a manual destination transaction. Confirm the token’s Ethereum contract address before sending, especially if you need it for a specific app.
