DEX and decentralised trading
How to use a decentralised exchange through your own wallet: connecting, signatures, token permissions, leverage risks and disconnecting the site when you are done.
What you will be able to do
- Explain how a DEX differs from a centralised exchange (CEX)
- Read a signature request and understand what you are confirming
- Limit a token permission to the amount you need
- Understand margin, leverage and the liquidation price
- Disconnect a site and revoke permissions you no longer need
Who this course is for
