    Unrekt enables the trading of locked liquidity, allowing you to secure profits from failed projects LPs. But how Unrekt makes this possible? Well our dApp allows devs to sell their locked LPs, turning them into a very profitable and secure investment option for those buyers willing to wait for the unlock time.
