ZK Region Verification
Zero-Knowledge Region Verification
Audience: Testnet users (optional), Mainnet users (mandatory) Goal: Understand and complete region verification using zero-knowledge proofs through Self or ZK Passport identity providers.
Why Region Verification Matters
Twilight uses zero-knowledge region verification to meet regulatory requirements while preserving user privacy.
Instead of submitting documents or identity data, users prove—cryptographically—that their passport was issued by a supported APAC country.
No personal details, images, or identity records ever leave your device.
Verification Requirements
Testnet
Optional
Completing region verification earns bonus points and eligibility for airdrop rewards.
Mainnet
Mandatory
Only users verified from supported APAC countries can trade or provide liquidity.
Each Twilight address must be verified independently. The indicator at the top-right turns green once verification is complete.
Supported Verifiers
You can verify your region using either of the following zero-knowledge identity providers:
Self.xyz
A privacy-first identity wallet that lets you prove nationality using cryptographic credentials from your device.
ZK Passport
A decentralized passport verifier using ZK proofs to confirm your country of citizenship without exposing any personal data.
Both methods issue a non-reversible proof token bound to your Twilight address.

China (CN), Indonesia (ID), Japan (JP), South Korea (KR), Mongolia (MN), Malaysia (MY), Nepal (NP), Singapore (SG), Thailand (TH), Turkmenistan (TM), Uzbekistan (UZ), Vietnam (VN), Australia (AU), New Zealand (NZ), Bangladesh (BD), India (IN), Kazakhstan (KZ), Maldives (MV), Philippines (PH), Tajikistan (TJ), Taiwan (TW)
Step-by-Step Verification Guide
1. Access the Verification Page
Look for the region verification indicator in the top-right banner of the Twilight interface.
— When red, it means your address has not yet been verified.
— Click the indicator to open the Region Verification page, which provides full step-by-step instructions.
— Once verification is complete, the indicator turns green.
If your indicator is already green, clicking it will simply display a confirmation message and return you to the main dashboard.
2. Choose Your Verification Method
You’ll be prompted to select between:
Self.xyz
ZK Passport
Choose the provider you prefer.
3. Scan the QR Code
If using Self.xyz:
Open the Self app on your mobile device.
Scan the QR code shown on the page.
Follow the on-screen instructions in the app to verify your passport country.
Keep the Twilight tab open until verification completes.
If using ZK Passport, follow the same process through the ZK Passport app.
4. Confirmation
When verification succeeds:
The red indicator changes to green.
Your Twilight address is tagged as region-verified.
You can proceed to trading, or providing liquidity.
⚠️ Verification is tied to each address or subaccount. Repeat if you use multiple addresses.
Notes & Troubleshooting
QR code doesn’t scan
Refresh the page and retry. Ensure your phone camera or app supports QR scanning.
Verification not completing
Keep the verification page open during the process; closing or refreshing interrupts it.
Unsupported country
Twilight currently only verifies passports from supported APAC countries.
Indicator still red after verifying
Wait a few minutes or reconnect your wallet. The frontend will refresh your status automatically.
Privacy Commitment
Twilight’s region verification system is fully privacy-preserving:
Only a cryptographic country proof is stored.
No document or images ever leave your device.
Proofs are one-way and non-reversible.
This ensures compliance with future regional access requirements — without compromising the core principle of user privacy.
