How to Collect Verified Crypto Wallet Addresses for Whitelists, Allowlists, Waitlists, and Airdrops

Introduction

Controlling who gets into your allowlist, whitelist, waitlist, or airdrop starts with knowing who your audience is, and the wallet address is the identity that counts. For a long time there was no reliable way to collect and verify those addresses, so teams could not fully trust the data they gathered. Most still ask users to copy and paste a wallet address into a generic form like Typeform or Google Forms. That approach is easy to get wrong, slow, and it never confirms the identity behind the address. 

This guide walks through how to use BlockSurvey to collect verified Web 3 identities for whitelist, waitlist, and airdrop registration. 

A step-by-step guide to using BlockSurvey for Web 3.0 wallet addresses

Step 1: Add a Web 3 Identity Verification component

If you're an existing member, go to Design Builder and click the 'Add Question by Type' button. In the list of categories, find the 'Web 3.0 Identity Verification' component. There you'll see every blockchain network supported for verifying user identities.

Step 2: Select a Blockchain Network

BlockSurvey currently supports major blockchain networks such as Stacks, Bitcoin, Solana, Ethereum, Polygon, and others. To make identity verification work across networks, several wallets are integrated, including Brave Wallet, Leather Wallet, Xverse Wallet, MetaMask, Phantom Wallet, Wallet Connect, and Coinbase Wallet. Choose the network where you want to collect wallet addresses, and BlockSurvey handles the rest. Based on the network, the right wallet choice is shown to your audience, on both desktop and mobile. Below is a sample screenshot for collecting Bitcoin and Stacks wallet addresses on the Stacks network. 

Step 3: Wallet address collection - User Verification Process

Once the BlockSurvey is created, hit Publish and share the URL with your audience. Here is what the wallet address collection looks like. See the screenshot below.  When the user clicks the 'Connect and Verify' button, that action launches the matching wallet application and starts the user's identity verification.

Step 4: Wallet address collection - Account Selection and Message Signing

Users pick the account they want to connect and then sign a message to verify their identity. The system retrieves basic public information, such as the wallet address, network provider, decentralized namespaces, and the wallet provider used for verification.

Step 5: Wallet address collection - Verification Confirmation and Submission

Once the user's identity is verified, a confirmation message appears, as shown below. Note: if the identity verification question is set as required, users have to finish verification before they can submit the BlockSurvey.

Step 6: View and Analyze the Collected Data

Now that the wallet address is collected, you can view and visualize the data from the BlockSurvey Analytics page. The sample screenshot below shows Bitcoin Taproot, Bitcoin Segwit, and Stacks wallet addresses collected from the Stacks Network. 

Now that you have seen how to use BlockSurvey for wallet address collection, here are some of the use cases it fits.

What are some Use Cases of Web 3 / Crypto Wallet Address Collection

1. NFT Whitelisting: While preparing for your presale, you need a validated list of addresses from your audience. As you build a whitelist through collabs, partnerships, and outreach, use BlockSurvey to collect verified wallet addresses. That way only genuine users with verified identities can mint or purchase NFTs. It cuts down on fraud, keeps things fair, and reduces the manual verification work during onboarding. 
2. Decentralized Finance (DeFi) Platforms: DeFi platforms can also build verified lists for airdrops, presales, and token sales. By adding BlockSurvey to their data collection, they can find and track active Web 3 participants in their ecosystem, which opens up ways to identify and reward active users.
3. Initial Coin Offerings (ICOs) and Token Sales: As with NFT whitelisting, you can verify identity during ICOs and token sales using Web3 wallets in forms and surveys. Only verified participants can contribute to the project, which lowers the risk of fraud and regulatory issues and keeps the participation process simple. We built a Token KYC form you can use to verify customer identity information.
4. Airdrops: Web 3.0 wallets let you verify the identity of users taking part in airdrops through forms and surveys. That way only genuine users receive the airdropped tokens or assets, which cuts down on fraud and abuse. By adding BlockSurvey to airdrop registration, project teams can also target their audience better and gather more accurate user data. Here is a sample NFT Airdrop form.
5. Secure Voting and Governance: BlockSurvey supports collecting data through forms & surveys for Web 3.0 companies. For secure and transparent on-chain voting, we also have an open-source tool called Ballot. Users cast their votes with their own wallet address, so votes are tamper-proof and reflect what the community actually wants. Feel free to give it a try. It is free. 
6. Allow List Management: With BlockSurvey in their forms and surveys, Web 3 businesses can manage allow lists for events or campaigns. Only verified and authenticated users get access to specific content, join events, or claim exclusive promotions.

Benefits of Verified Wallet Addresses for Web 3 Companies:

1. Reduced Fraud: Identity verification with Web 3.0 wallets helps cut down on fraud by confirming that users are who they say they are. That protects both businesses and users from the scams and phishing attacks that show up in the crypto space. 
2. Simplified User Onboarding: Collecting Web 3.0 addresses in a crypto-native way gives Web 3 natives an onboarding flow that feels familiar. Fewer people drop off or abandon the form, so engagement goes up. 

Conclusion

Using BlockSurvey for your Web 3.0 data collection through forms & surveys gives you a Web 3.0-focused experience with better security, privacy, and usability. BlockSurvey is becoming a standard part of data collection for Web 3 companies. Teams working on NFTs, DeFi, and DAOs are already seeing the benefits of collecting verified Web 3.0 wallet addresses.
