# Collect fees

**So, now we will tell you how we collect commissions...**

First, Blast L2 allows you to get all the unspent gas back. We collect available gas with Blink Governance, wrap to $WETH and sent to Blink Farm.

Secondly, Blast provides an amazing and unique technology Yield $WETH 4% and $USDB 5%. All possible $WETH and $USDB are in Blink pools. Therefore, all Yield from pools is sent to Governance Blink, wrap to $WETH and sent to Blink Farm.

Thirdly, all DEX take a commission for the swap, this commission goes to the liquidity providers. But what if we do it differently? 0.3% commission is charged to the trader. It is divided into two parts: 0.25% goes to Governance Blink, wrap to $WETH and send to Blink Farm. 0.05% remains in the pool and is sent to the liquidity provider when withdrawing liquidity.&#x20;

You may think that we have deprived liquidity providers if we give them only 1/6 of all commissions, but this is not the case. Liquidity providers can stake a position in Blink Farm and get access to all earned commissions, not just pool commissions. [More](/docs/economic-model/blink-farm.md). As well as liquidity providers participate in points farming and will receive airdrop. [More](/docs/economic-model/airdrop-usdblink.md)
