# Fees

### Swap

No fees are charged when *swapping* on Astrolesent. We add a small fee when third-parties that use our APIs or trading widgets add their fee.

### Bridge

A 0.1% fee is charged when using the cross-chain bridge.

### Limit Orders

A 0.1% fee is charged when adding limit orders. 

However, traders can earn fees by providing liquidity on Astrolescent. This means placing limit orders that aren't immediately matched on the orderbook. Once the order is eventually matched, the liquidity provider receives a fee of up to 0.35% of the trade's value.

This means it is possible that a negative fee is "charged" when creating the limit orders.
