Use an address meant for the chain where your swapped asset will arrive. If you are comparing cross-chain swap services, this small detail matters: a valid-looking address can still be wrong for the destination.
What does the recipient address tell the service?
The recipient address tells the swap service where to send the final asset. It is the destination, not necessarily the address you used to start the swap.
A cross-chain swap has two sides: the asset leaves on one network, then the received asset is sent on another. For example, you might start with an asset on BNB Smart Chain and want the result on Polygon. The address must be usable on Polygon, even if the source wallet address looks similar. That is a separate question from quickswap BNB Chain to Polygon swaps, which concerns the route between those networks.
quickswap.dev can move assets between chains and exchange them as part of that journey. Address choice still depends on the destination wallet and network you want to receive on.
Why do address formats differ?
Each blockchain defines how an address is written and checked. Ethereum-style networks use a 20-byte address, usually shown as 40 hexadecimal characters after “0x.” Hexadecimal is a number system using digits 0–9 and letters A–F.
Ethereum, BNB Smart Chain, Arbitrum One, and Polygon use this address style. The same wallet may show the same address on each network, but its balances and activity remain separate on each chain. Matching characters do not prove that you picked the right destination network.
Solana addresses use a different format: a 32-byte value displayed as letters and numbers in base58. Base58 is a text encoding that avoids some easily confused characters. A Solana address will not look like a typical “0x” address, and you cannot paste an EVM address there as a substitute.
How should you choose the recipient?
Choose the address from the wallet that will receive the final asset on the destination network. Check the network name in that wallet, then copy its receive address for that network. A wallet may support many chains, so selecting the right wallet alone is not enough.
Here is a common mistake: someone wants an asset on Solana but pastes their familiar Ethereum-style address. The fix is to open the receiving wallet’s Solana account and use its Solana address. Before confirming, compare the first and last few characters with the wallet’s displayed address.
Also check whether the address belongs to a person or to a token. A token’s mint address identifies the asset; it is not a personal destination. On Solana, a token account is a chain account that holds a particular token for a wallet. Unless the service specifically asks for one, use the receiving wallet address rather than a token mint or token account.
What checks matter before you send?
Confirm both the destination network and the recipient address before approving the source transaction. Address format can help catch a mismatch, but it cannot confirm that the chosen network is correct. An EVM address may look valid on several EVM networks while still pointing to a different chain’s balance.
Some EVM wallets display mixed-case addresses. That casing can act as a checksum, a pattern that helps detect typing errors. Keep the copied form intact instead of retyping it. If the destination address was supplied by someone else, verify it with them through a trusted channel.
Address setup does not determine the swap’s price or timing. Those depend on the route, network conditions, and service terms. Your next step is simple: decide which chain should hold the final asset, open that chain in the receiving wallet, and use its matching address.
