How to swap pUSD at the best rate on LCX Liberty DEX

Step 1: Put the pair in the card
pUSD on one side, the token you want on the other, for example pUSD to USDC.e, on any network pUSD is on. Selling pUSD is the same swap with USDC or ETH on the other side.
Step 2: Let the router compare
We quote pUSD across 12 pools on Uniswap and Ramses, and split the order between up to eight of them when that pays more.
Step 3: Check the quote
The card shows the rate, the route, the price impact and the least you will receive. If the price moves past your slippage limit (0.5% by default) before the swap lands, it is refused and nothing is traded.
Step 4: Approve, then swap
Your wallet first asks to let the router spend the exact pUSD you are swapping, then sends the swap. We take no fee; you pay gas and the pool's own fee.

Selling pUSD

Selling is the same swap in the other direction: pUSD on the side you pay with, and a stablecoin or ETH on the side you receive. A stablecoin holds the value steady; ETH keeps you in the network’s own coin.
