Galxe Quest Platform Integration: Campaign Setup and OAT Issuance

After launching an NFT collection or IDO, you often need to verify on-chain actions of participants and reward them. Galxe — the largest Web3 quest platform with 20+ million users — automates this via credentials and OATs. We integrate your project with Galxe end-to-end: configure credentials, verify quests through subgraph or API, issue OATs, and provide analytics. Savings on building your own quest infrastructure can reach 70%. Get a consultation — we'll assess complexity and timeline in one day.

How Galxe Solves Quest Campaign Tasks

Galxe lets projects verify task completion: Twitter follow, voting, token holding, or transactions. Verification happens via subgraph (for on-chain actions) or API (for custom logic). Our experience shows API mode is more flexible in 70% of cases: it supports any off-chain data and combined conditions, though it requires more development. For one client, we built an endpoint that checked a deposit into a Uniswap V3 liquidity pool and wallet balance of at least 0.1 ETH for 3 days. This was impossible via subgraph — the API handled it in 1.2 seconds per request, with 92% successful verifications. Average response time of a configured endpoint is under 2 seconds.

Important: Galxe does not pass authorization in the request. Without protection, anyone can poll your endpoint, incurring extra costs. Adding a shared secret via query param (e.g., ?secret=xxx) eliminates this risk.

Two Verification Modes: Comparison

Subgraph mode suits standard on-chain actions; API is for unique scenarios. In one project, we implemented verification by NFT presence on other networks via API — this was 3× faster than deploying a separate subgraph for each network. For API-based mode, a published HTTPS endpoint returning JSON with is_eligible is required. Example in Express:

app.get('/galxe/verify', async (req, res) => { const { address } = req.query; const eligible = await checkEligibility(address as string); res.json({ is_eligible: eligible }); }); 

Typical Integration Mistakes and Their Solutions

What Are Credential and OAT?

After successful verification, Galxe creates a Credential — an off-chain record of the achievement. Based on it, you configure issuance of an OAT (Soul-bound NFT on Galxe Chain) or access to subsequent quests. For custom rewards, use the Galxe Smart Contract: deploy your contract on Galxe Chain, then Galxe calls claim() on behalf of the user.

Details for setting up Galxe Business Dashboard:

1. Create a campaign and select a credential.
2. Specify the endpoint for verification (if API-based).
3. Configure OAT issuance rules and additional rewards.
4. Test with test addresses.
5. Publish the campaign.
