Biswap lets you swap tokens from your own wallet across 30-plus chains, while its older liquidity products are now handled through withdrawals. If you are used to a centralised exchange, the main change is where the assets sit: you hold them and approve each on-chain action. The chain you select matters as much as the token name.
For a Biswap swap, Biswap presents a proposed route, and your wallet presents the transaction you are about to authorise. Read both before signing. The number to focus on is the amount of the correct token expected in your wallet on the correct chain, after the route’s costs.
What Is Biswap Today?
It is chiefly a wallet-connected interface for same-chain swaps and cross-chain trades. Its current exchange uses LI.FI to find routes through available exchanges and bridges, rather than requiring every trade to use one liquidity pool. A route is the sequence of steps that turns your input token into the token you requested.
For example, a same-chain route may trade directly against a pool on BNB Smart Chain. A route from BNB Smart Chain to Base may swap the input, bridge an asset between chains, then swap again on Base. You approve and start the source-chain transaction; the later steps can take longer to settle. A quote is an estimate until those steps finish.
How Do You Swap From Your Wallet?
You need a self-custody wallet with the input token on a supported source chain and enough native currency to pay gas. BNB pays gas on BNB Smart Chain; ETH pays it on Base and Arbitrum. If you withdraw funds from a centralised exchange first, choose the intended network there too. Sending a token to the right wallet address on the wrong network will not put it on the chain you meant to trade from.
Connect your wallet, select the source chain and token, then select the destination chain and token and enter an amount. A token’s name alone is insufficient: check its contract address when there are similarly named assets, especially for bridged and native versions of a stablecoin. Before confirming, review these four parts of the quote:
- Destination: the receiving wallet address, chain and exact token contract.
- Amount: the estimated output and the minimum you may receive.
- Route: any bridge and intermediate swaps between input and output.
- Costs: network gas, route fees and any fee deducted from the output.
If the input is a token rather than a chain’s native currency, you may first need to approve a spending allowance. That approval is a separate on-chain transaction and may cost gas; it gives a contract permission to move up to the amount authorised. I would choose a limited allowance when the wallet offers that option. After it confirms, inspect the swap transaction itself and sign only if its token, amount and chain still match your plan.
Suppose you start with 100 USDC on BNB Smart Chain and want USDC on Base. Before the trade, your wallet shows the 100 USDC on BNB Smart Chain; afterward, the relevant balance is the USDC received on Base, which may be less than 100. Check whether the destination token is the version you actually need. If a cross-chain transfer is still processing, use its route status before sending the trade again: a slow arrival is not proof that the first transaction failed.
What Will the Trade Cost?
The effective cost is the difference between what you spend and receive, plus gas paid separately. The displayed rate can reflect pool trading fees, bridge fees and price impact, which is the change your trade causes in the available price. Biswap’s older V3 documents list pool fee tiers from 0.015% to 1%; those tiers are not a flat fee for every route shown by the current exchange.
For example, say you spend 100 USDC, the quote estimates 99 USDC on the destination chain, and source-chain gas costs another $0.50. If the route’s trading and bridge fees are already reflected in the 99 USDC, your effective cost is about $1.50. Do not add those fees a second time. If a fee is shown as an extra payment, include it when comparing routes.
Slippage tolerance sets how far execution may move from the quote before a transaction fails; it is not a promised fee. At 0.5% tolerance, a quote of 99 tokens could permit roughly 98.505 tokens before other route-specific conditions. A tighter limit protects the output but can make a volatile trade fail, still leaving you with spent gas. For a first trade, I would use a small, liquid same-chain pair and judge the minimum received before considering a cross-chain route.
What About Liquidity Pools and Other DeFi Features?
The old farms and staking products are closed, and existing V2 and V3 pool positions are handled through legacy withdrawals. Biswap’s 2025 closure announcement also covered launchpools, liquid staking and the BSW investment pool. Its newer withdrawal flow lets holders check for remaining legacy assets, including liquidity positions. Historical instructions for adding liquidity or earning farm rewards should therefore not be read as a current offer.
Providing liquidity means depositing assets into a pool so traders can swap against them; it is a different decision from making a swap. In a V3 position, you also set a price range. If the price leaves that range, the position stops earning trading fees and can end up entirely in one of its two tokens. Fees earned may not make up for that change in holdings, often called impermanent loss.
Before acting, ask yourself: after the quoted costs and possible price movement, will the exact token you want arrive on the chain where you need it?
