If you hold ETH on Ethereum but need SOL on Solana, the aim is to receive SOL in a Solana wallet without arranging a separate bridge transfer and trade. The choice that matters most is what asset you want to receive and which network you need it on. ### What Is super bridge, and What Do You Receive? It is a cross-chain bridge and swap service: you send an asset from one blockchain and receive an asset on another supported blockchain. A bridge usually keeps the asset type broadly the same, while a cross-chain swap changes it. In either case, the receiving wallet must support the destination network and the particular token delivered there. For example, ETH on Ethereum and ETH on an Ethereum layer 2 are balances on different networks, even though both are called ETH. Moving between them requires a bridge route. Changing ETH into SOL on Solana also requires a swap; selecting Solana alone does not turn ETH into SOL. ### How Does a Cross-Chain Transfer Work? A cross-chain transfer records your payment on the source network, then delivers the agreed asset on the destination network. The coins do not literally travel from one blockchain to another: each chain keeps its own ledger. The route connects the two by verifying the source transaction and arranging the destination payment. Routes use different mechanisms. Some lock a token on the source chain and issue a token representing it on the destination; others burn a token and issue its counterpart, or pay from liquidity already held on the destination chain. Ethereum’s bridge documentation describes these designs. The mechanism matters because a token representing BTC on Ethereum is an Ethereum token, with backing and bridge risks that native BTC on Bitcoin does not have. A swap adds a trade to that handoff, so the asset received can differ from the asset sent. Say you start with BTC and want ETH on Ethereum: the desired result is ETH, not a token representing BTC. If you instead want to use Bitcoin’s value in an Ethereum application while retaining exposure to BTC, a suitable BTC-backed token may be the intended result. ### How Do You Make Your First Transfer? You make a first transfer by identifying the asset and network you have, then the asset and network you want to receive. Check those four details before sending anything. You also need enough of the source network’s native coin to pay its transaction fee, often called gas. Once those details are clear, choose a route for that exact combination. At that point, [super bridge](https://superbridge.us/) lets you move and swap assets across networks in one flow, so you can target the coin you need in the receiving wallet. For a crypto super bridge transfer, compare the expected destination amount with what you are spending before authorizing the source transaction. 1. Identify the asset and network shown for your balance in the sending wallet. 2. Choose the exact asset and network you want the receiving wallet to hold. 3. Copy a receiving address from a wallet that supports that destination network. 4. Check the expected amount received and the costs of the route. 5. Authorize the required source-chain transaction in your wallet. 6. Check the source transaction and the destination balance before treating the transfer as complete. A common mistake is assuming that a familiar-looking address proves the network is right. Ethereum and BSC addresses can look alike, but funds sent on one network do not automatically appear on the other. Read the network name in the receiving wallet as well as the address, and use a small test transfer first if the amount is significant to you. ### What Should You Compare Before Sending? Compare the asset you will actually receive, its net amount, the route’s risks and the expected wait. A route with a lower stated fee may deliver less after a swap because of price impact, the change in price caused by trading against available liquidity. These are the main parts of the comparison: * **Source-network fee:** the cost of recording your outgoing transaction. * **Bridge or routing charge:** any charge for arranging delivery across networks. * **Swap price:** the exchange rate and possible slippage, meaning a change between the expected and executed rate. * **Destination asset:** the native coin or the specific token your wallet will receive. For an illustrative $100 total spend, $1 of source-network fees, a $0.50 routing charge and $0.75 of swap price impact would leave about $97.75 of destination value before market prices change. Actual costs depend on congestion, liquidity, trade size and the route. Check what a wallet signature authorizes, especially any token-spending approval, and never give a bridge your wallet’s recovery phrase. ### Common Questions These answers cover the network, asset, cost and timing details that usually decide a first transfer. Availability and estimates depend on the exact route you choose. #### Which blockchains are supported? The service is described as covering Bitcoin, Ethereum, BSC, Solana and major Ethereum layer 2 networks. That does not mean every asset can move between every pair of networks. Check the specific source asset, destination asset and network pair you need before sending; a route for ETH may differ from one for a token held on the same chain. #### Can I bridge Bitcoin to Ethereum? Yes, if a route is available for the particular result you want. You can seek ETH on Ethereum through a cross-chain swap, or a token representing BTC on Ethereum through an appropriate bridge route. Native BTC remains on Bitcoin; it cannot become native to Ethereum. Confirm the destination token rather than relying on the word “Bitcoin” alone. #### How much does a super bridge swap cost? There is no single cost for every swap. Source-chain gas, a bridge or routing charge, and the exchange rate all affect how much arrives; destination costs may also apply. Compare the total you spend with the estimated amount of the requested destination asset, since a small stated fee does not necessarily mean a cheaper transfer. #### How long does a super bridge transfer take? It can take minutes or longer, depending on source-chain confirmation, the route and destination settlement. Bitcoin says a transaction usually gets its first confirmation in about 10 to 60 minutes; a route may require more. A canonical withdrawal from an optimistic Ethereum layer 2 can take roughly seven days, while a liquidity-funded route may deliver sooner for a charge. For your first transfer, keep the sequence simple. These three checks catch the mistakes most likely to change what arrives: * Match both the destination asset and destination network to your purpose. * Check the receiving address and the net amount before signing. * Confirm the asset in the destination wallet before making another transfer. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://stablecoin-reference.gitbook.io/stablecoin-reference-docs/super-bridge-move-and-swap-crypto-across-blockchains.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
