Swaps

Single-hop and multi-hop swaps, routing, and slippage settings.

BEX lets you exchange one token for another when liquidity exists for the pair. Use the BEX interface on Bera Hub (navbar) for swaps.

Single-hop and multi-hop swaps

If adequate liquidity exists in a given pair, BEX most likely executes the swap as a single hop. Single-hop swaps incur less exchange and gas fees, making them the preferred method.

However, when a trade between the input and output token does not provide the best overall price (or the trading pair does not exist as a single pool), BEX can perform a multi-hop swap. Multi-hop swaps involve chaining swaps across multiple pools to find the best overall price. The process of finding a cost-efficient multi-hop path is called routing.

Intermediate tokens

In a multi-hop swap, intermediate tokens are the tokens held temporarily when swapping through a sequence of pairs. Intermediate tokens in BEX are never transferred because settlement occurs based on the net debit against the entire BEX protocol.

Swap parameters

When initiating a swap, you can define the following parameters:

• Quantity: The amount of tokens to swap, which can be specified as either a fixed input quantity or a fixed output quantity.
• Slippage: The maximum acceptable difference between the expected and actual price of the trade. Slippage is expressed as a percentage and represents the worst-case price impact you are willing to accept. If the actual price impact exceeds this threshold, the swap transaction will revert.
