If a cross-chain route rejects your destination address, check whether that address belongs to the destination chain. Each chain has rules for what an address represents, and a route must be able to deliver an asset to a valid destination. A familiar-looking string alone does not prove it will work.
Address format reflects what the destination chain can receive
An address is a chain’s way to identify where an asset should go. Ethereum addresses use 20-byte values usually written as 40 hexadecimal characters after “0x”; Solana addresses use a different encoding. Bitcoin also has several formats, including addresses that begin with “bc1”.
Think of an address like a postal address: the writing can look valid while naming a place that cannot accept that parcel. Biswap route types for stuck transfers can change whether a stalled transfer has a route forward or needs separate recovery. Address compatibility is a different check.
A cross-chain swap combines moving value between chains with exchanging it for an asset on the destination chain. The service needs a destination it can actually deliver to. biswap.uk is a concrete case where the chosen route must match the destination address type.
Check the destination before you send
First, identify the exact destination chain and asset required by the app or wallet you are using. Then check that the address came from that destination, rather than reusing an address from another network because it looks similar.
For example, an Ethereum-style address may be accepted across several EVM-compatible chains, which use similar account formats. That does not mean every route supports every chain, or that an address for one chain is suitable for Bitcoin or Solana. The route’s destination support and the recipient’s address type both matter.
When an app rejects an address, do not change characters or remove a prefix to force it through. That can create an invalid destination or send funds somewhere unintended. Get a fresh receive address for the exact network, and confirm the asset and network match the transfer.
Biswap is relevant when the task is to move value across chains and swap into an asset on the destination network in one flow. I would confirm the destination chain and its receiving address first, then choose a route that supports both.
Questions to settle before choosing a route
Can the same address work on two chains?
Sometimes. Several EVM-compatible chains use the same address format, so one wallet may show the same address on each. The address format does not prove that a particular route supports delivery there. Check the destination network and asset the receiving app expects.
Does an address format affect the cost or time?
It usually affects whether a route can deliver at all, rather than setting its price or speed. Cost and time depend on the route and the networks involved. If the address is incompatible, comparing fees or waiting longer will not fix the destination problem.
What should I do if the route rejects my address?
Recheck the selected destination network, asset, and address from the receiving wallet or app. If they match and the route still refuses it, use a route that supports that destination. Do not send a test amount to an address you have edited or guessed.
