Builder Verification

All Builders who wish to access the full range of MSU Builder features — including API usage, app registration, and monetization — must complete identity verification.

The required verification type differs depending on whether you are an individual or a legal entity:

• KYC (Know Your Customer): For individual Builders and teams
• KYB (Know Your Business): For legal entities (corporations)

　

1. Why Verification Is Required

Verification is required to maintain a safe and compliant Builder ecosystem. It serves three main purposes:

• Preventing misuse and protecting the ecosystem
• Enabling secure transactions and asset transfers
• Unlocking advanced features such as API access, app registration, and monetization

　

2. Verification Levels and Feature Access

MSU Builder has three verification levels. Higher levels unlock more features.

Feature	Level 0	Level 1	Level 2
API Keys Limit (Max)	❌	1 per app	3 per app
READ API	❌	✅	✅
Action API	❌	❌	✅ (only applicable)
App Registration	❌	❌	✅

MapleStory N	❌	❌	❌
1st-party Synergy Apps (e.g. Smithy)	❌	❌	❌

• Level 0 is the default level upon wallet connection and account creation.
• Level 1 is intended for testing and prototyping.
• Level 2 enables production use and monetization of Synergy Apps.

• Warp and Transfer limits are controlled integrately.
• Revenue claim is subject to minimum thresholds and settlement policies as defined in the Builder Terms.

　

3. How the Verification Process Works

The verification process follows these steps:

1. Create a Builder account on the MSU Builder platform.
2. Apply for API access on the MSU Builder platform.
3. Once the application is received, a KYC/KYB verification link will be sent to the registered email address.
4. Complete KYC or KYB verification through the link provided in the email.
5. Check the KYC/KYB approval status and your APL key from the MSU Builder platform.

• The verification link is sent upon API access application submission to the e-mail on the application.
• KYC approval process can be completed within 2-3 business days, whereas, approval process could take upto 7 business days. Delays may occur.

　

4. KYC vs. KYB

The verification type is determined by how you are participating in MSU Builder. Choose the type that applies to you:

4.1. KYC — For Individuals and Teams

Individual and team that are not legal entities are required to complete KYC verification. The required documents by level are as follows:

• Level 1:
  • Passport or government-issued ID, along with a Selfie
• Level 2:
  • Proof of address document issued within the last 3 months, containing the same full name and address as verified in Level 1 (e.g., utility bills, bank statements)

• Selfie verification must be completed in an environment where your identity can be clearly confirmed, following the instrucion from the verification service.
• For more details on accepted ID types and other requirements, refer to the guidance within the Verification page.
• For non-incorporated teams, the representative or leader of the team should complete the KYC process for the whole team.

4.2. KYB — For Business Entities

Legal entities (corporations) are required to complete KYB verification. KYB requires different documents from KYC. The required documents include;

• Certificate of Incorporation
• Memorandum / Articles of Incorporation

• KYC verification for the Ultimate Beneficial Owner (UBO) will be conducted separately.
• Additional documents may be required depending on the type of legal entity and jurisdiction. Detailed guidance will be provided during the verification process.

4.3. Upgrading Your Verification Level

KYC verification grants Level 1 access. Builders can upgrade to Level 2 by completing additional verification requirements. Each level will be granted under the following condition;

• Level 1 (Testing): After completing initial KYC verification
• Level 2 (Production): After completing KYB verifitation or additional verification following KYC Level 1 or KYB verification

Switching from an individual account to a legal entity account requires a separate KYB verification.

　

5. If Your Verification Is Rejected

If the verification is rejected, Builders can reapply by correcting the issues identified during the review process. Additional document submission may be required, and retrial is available within the allowed number of attempts.

For inquiries related to re-verification, please contact [e-mail].

　

6. Data Privacy

All personal or company data submitted during verification is handled securely and is used only for verification and compliance purposes in accordance with applicable policies.
