Following the tremendous success of the Plasma ICO, the highly anticipated Ethereum L2 project MegaETH is now open for registration and KYC (identity verification) on the Echo/Sonar platform. This guide aims to detail the key steps, required materials, and considerations for participating in this popular ICO.

A few minutes to raise 50 million dollars, with an ICO price of 0.05 dollars, directly yielding 20 times the return upon listing, and at its peak, it brought ICO investors returns as high as 3260%.

The success of the Plasma ICO has almost made everyone realize that the frenzy of ICOs may soon reappear. From that moment on, all eyes turned to the platform behind it—Echo.

It not only carried the explosion of Plasma but also attempted to reshape the rules of new token launches with its new Sonar feature. Related reading: “Echo launches new feature Sonar, can it create a 'compliant ICO' market?

No one wants to miss out on the next "Plasma." Now, a new wave of excitement is gathering. The next project that may replicate the Plasma myth, MegaETH, is opening registration on the Echo platform.

This article will provide a complete guide on: how to complete the registration and KYC for MegaETH, how to use Echo and Sonar, and how to join the most active investment groups.

1. How to KYC for MegaETH

The hottest ICO on Sonar right now is MegaETH, with the registration period from October 15 to October 27, leaving 6 days until the registration deadline. The KYC identity verification process involves several steps, but if the information is complete and smooth, it can almost be approved instantly. If waiting is required, it will be for manual review, which takes at least 1-3 days, so it’s best to complete KYC as early as possible.

1. Prepare Documents

Prepare necessary documents including a high-definition photo of your passport or driver's license, a mobile phone capable of facial recognition, and a utility bill or bank statement from within the last 3 months.

Chinese addresses are listed as prohibited areas for participation, so you need to submit proof of address from another region. Many bloggers on Twitter discuss ways to resolve address proof issues, so we won't elaborate here. Our subsequent steps will mainly use the example of a mainland passport and Hong Kong address proof, along with bank statement documentation.

2. Visit the MegaETH Registration Page

According to community analysis, entering the KYC process from the MegaETH registration page is easier than entering from Sonar, so we will access it from the MegaETH registration page.

Once entered, you need to authorize a data connection by clicking "Authorize" to agree and continue.

3. Complete Personal Information

On the personal information completion page of the MegaETH platform, you can first fill in the "Social Media & Work" links for Twitter, Discord, and GitHub. Try to choose accounts with rich interactions, as past participation and contributions in the MegaETH and Ethereum ecosystem may increase your chances of receiving allocations during oversubscription.

Additionally, click "Add Additional Wallets" to upload up to 3 of your own wallets with rich on-chain interaction history, which can also increase your chances of receiving allocations during oversubscription.

Next is the most important step, "Identity Verification." First, connect a main wallet, and as mentioned earlier, try to use a wallet with rich on-chain interaction history.

Then click "MANAGE ON SONAR," where you will need to use the passport photo and bank statement prepared in step 1.

4. Identity Verification

After clicking "MANAGE ON SONAR," you will enter the identity verification process, where you need to upload two documents as shown in the image.

First, click on the first option, "Proof of identity with a photo," which is the identity proof with a photo. You can first try the passport photo; if that doesn't work, you can use the driver's license photo. Note that the photo must be of high clarity, and the uploaded photo should be the downloaded passport photo, not a screenshot, as the system will fail if it detects a screenshot.

After uploading, you will proceed to the facial recognition step. Make sure to take the photo in a well-lit area, ensuring your face is clearly visible without obstructions.

After clicking "Start liveness check," you will receive a prompt to complete it on your phone. Click "Continue on phone," and a QR code and link will pop up. Scan the QR code or copy the link to complete facial recognition.

Once facial recognition is complete, return to your computer. The page will move to the next step, where you need to upload proof of address. If you receive an email indicating failure, try uploading other proof documents.

5. Complete Registration

After passing KYC, you will receive an email/platform notification, and the official details of the sale will be announced after October 27. Returning to the homepage, we can see "Qualified for this sale," indicating that this wallet has passed KYC and eligibility review.

Note that during the payment phase, there may be a secondary facial verification or a request to resubmit proof of address from the last 90 days, so keep an eye on the official Twitter of @megaeth_labs and email notifications from Sonar.

2. How to Create and Use Echo & Sonar

1. Register for Echo

After completing the MegaETH registration, we still cannot use Echo because the KYC channels for the two are different. Therefore, we need to go to Echo's registration homepage to complete the registration for Echo.

The registration here is simpler than before, so I won't go into too much detail. Just complete the following information settings: enable two-factor authentication (2FA); bind your X (Twitter) account or bind your Farcaster account; select your country of residence; agree to the user agreement; fill in your investment experience and identity information.

The only somewhat complex part is the Investor History questionnaire in step 6, which requires selecting investment experience, income amount, asset amount, understanding of lock-up, and dozens of other questions. If you deviate too much, the verification will fail. Here, try to highlight your rich investment experience, with an annual income of at least over 200,000 dollars or net assets over 1 million dollars. For professional questions you are unsure about, you can confirm with AI.

2. Join Groups

The group feature is one of Echo's highlights. Echo itself does not recommend or display specific trades, but group "owners" can.

After creating a group, "owners" can share their investments within the group. Members can join these groups and choose whether to co-invest based on the specifics of each transaction, participating under the same conditions.

All "group friends" will be merged into one investment entity, which will represent the funding for investments in target companies. The entire process is completed on-chain, using USDC as the settlement currency. In terms of profit distribution, "owners" will receive a certain percentage of the profits from "group friends" as a return; "group friends" only make money if the "owner" makes money.

Any Echo user can apply to create a group, but currently, the processing speed for applications is quite slow.

On the group page, we can apply to join the groups we are interested in. Before joining, we can see the number of members and the most recent deals in the group. Some groups are by invitation only, and only invited users can join.

Here, it is recommended to join groups with many members and well-known group owners, such as the group Club Cobie led by Echo founder Cobie.
