acrossbridge moves or swaps crypto between blockchains in one flow. It is a cross-chain bridge and swap service: you specify what you hold on one network and what you want to receive on another. The key choice is the output asset, because the same ticker can refer to different tokens on different chains.
The Output Is on the Destination Network
A completed transfer gives you an asset recorded on the destination blockchain. Coins do not travel between separate ledgers. Depending on the route, an asset may be locked on the source chain while a corresponding token is issued elsewhere, or funds already held on the destination chain may be paid out.
Before: you hold 0.01 BTC in a Bitcoin wallet. After: you could hold a BTC-backed token on Ethereum, or a different asset such as SOL on Solana, depending on the route you choose. A BTC-backed token is a representation with its own issuer or bridge risk; it is not native BTC. If you need SOL to use a Solana app, receiving a BTC representation does not finish the job.
Your receiving wallet must support the destination network and the exact token. Ethereum, BNB Chain and many layer 2 networks use similar address formats, but balances on those networks are separate. Bitcoin and Solana use different address systems. When a ticker is ambiguous, check the token’s contract address or, on Solana, its mint address.
A Route Combines a Bridge With a Swap When Needed
A route accounts for your deposit on the source chain, waits for confirmations and supplies the chosen asset on the destination chain. Bridge designs differ: they may lock and mint, burn and mint, or pay from available liquidity and settle later. A swap adds an exchange from the asset you deposit into the asset you want to receive.
The source transaction must confirm before the destination payment can complete. Sending an ERC-20 token may require a separate approval, which authorizes a contract to spend that token; sending native BTC does not use an ERC-20 approval. Track both the source transaction and the destination receipt, since a confirmed deposit alone does not show that the whole route has finished.
If you hold BTC on Bitcoin but need SOL on Solana, moving only a BTC representation would leave you with the wrong asset. At that decision point, acrossbridge lets you move and swap assets between those chains in one flow, so you can seek the asset you need on Solana. An acrossbridge swap addresses two choices together: where the value ends up and which asset you receive.
Cost and Speed Depend on the Route
The amount you receive reflects network fees, any bridge or routing charge and, when assets change, the swap rate. Gas is the network fee paid to process a transaction. At an illustrative quote, sending 100 USDC on Ethereum and receiving 98.60 USDC on Solana leaves 1.40 USDC less in the output, plus any source-chain gas paid separately. Compare the amount received and separately paid costs, not only a displayed fee percentage.
For a swap, inspect the minimum received amount as well as the estimate. Slippage is the difference between the quoted and execution rates, often caused by price movement or thin liquidity. Also check whether you will have the destination network’s native coin to pay for your next transaction; some routes provide it, while others require you to obtain it separately.
Waiting time depends on source confirmations, destination processing and route design. Bitcoin confirmation can take longer when its network is busy. A less obvious case is a canonical withdrawal from an optimistic layer 2 to Ethereum, which may take around seven days; a route funded by a liquidity provider can arrive earlier, with a different cost and set of risks.
A First Transfer Starts With the Exact Output
To use acrossbridge, first write down the source network and asset, then the exact destination network, asset and receiving address. Make sure the recipient accepts that token on that chain. An exchange deposit address, for example, may accept only specified networks even when the token name matches. Keep enough native coin for source-network gas where applicable, such as ETH on Ethereum or BNB on BNB Chain.
Before sending, compare the estimated and minimum output, verify the full receiving address after pasting it, and read what your wallet asks you to sign. A token approval is permission to spend tokens, so check its allowance as well as the transfer amount. If a route cannot deliver the asset you need, change the route rather than choosing a similar-looking token.
After the source transaction confirms, check the receiving wallet on the destination network. A token may arrive without appearing in the wallet’s default list; verify its token identifier before adding it. For your first transfer, send a small test amount above any stated minimum, then send the remainder once the intended asset appears.
