Someone asked me if there's a self custodial exchange where you could trade upto 100x BTC and ETH. Turns out there is one and it's called LeverJ. I've no idea how good or bad this exchange is but in case you were looking for one then you could check this out. DYOR.
However, as you can tell from the screenshots the volume is really low compared to any of the existing exchanges offering similar and better products. The liquidity is low. If you are trading tiny sizes then you could try this out.
On the bright side the fees are low but this is not a place I would use currently as the trading UI rather sucks currently and needs a lot of improvements to match up to any centralised offering today.
DeFi and DEXs have been gaining popularity lately and I would love to see a high volume DEX offering leveraged trading similar to Binance and Bybit. In fact if you are looking to trade for free then Phemex offers 0% maker/taker for premium customers.
