On-ramps and crypto aggregators aren't the same thing, and mixing them up stalls integrations

Stop Mixing Up On-Ramps and Crypto Aggregators

A critical integration insight for Web3 builders: *stablecoin on-ramps* and *crypto aggregators* solve fundamentally different problems. Treating them as interchangeable kills weeks of dev time.

**Crypto Aggregators** (Plaid-for-crypto model):

- Connect to existing wallets/exchange accounts

- Read balances, move funds between user-controlled accounts

Architecture Breakdown: Crypto Aggregators vs On-Ramps

- Zero KYC for existing holders

- **Cannot onboard new-to-crypto users**

- Convert fiat → stablecoins for any user

- Handle payment rails (cards, bank transfers, UPI, PIX)

Why This Integration Mistake Costs Weeks of Dev Time

- Manage KYC/compliance overhead

- Deliver tokens to specified wallet addresses

The integration choice depends on your user base. Building for crypto natives? Aggregators work. Need fiat onboarding? On-ramps are mandatory.

- **Widget**: Fast to ship, good for demand validation

The real question for Web3 product teams: are you building for existing crypto holders or driving mainstream adoption through fiat onboarding? Your infrastructure stack depends entirely on this answer.

The category confusion is real—but now you know the difference.
