To participate in Echo ICOs, you first need to sign up on the Echo launchpad platform. If you have previously participated in Sonar ICOs (MegaETH, Plasma, Harmonix, and others), you can simply log in using the same Google account or email you registered with for Sonar.

Next, complete the KYC verification and fill in the required investor information, then wait for the team to review your application. If you logged in using your existing Sonar account, KYC verification is not required.
Once approved, go to the “Groups” section and apply to the Cambria investment group. The review process may take some time.

If your application is accepted, deposit funds into your Echo wallet and allocate them to the Perpl ICO.
