Customer experience
A signed-in user selects a supported asset and amount in Wrooms Crypto, chooses Coinbase when available, and completes the purchase in Coinbase's hosted flow.
Coinbase Developer Review
Wrooms Onramp integration + Layer 7 network request
A reviewer-facing overview of the live Wrooms Coinbase Onramp integration, its security model, and the request to support Layer 7 (L7) as an EVM-compatible destination network.
Security boundary
Coinbase CDP credentials stay on the server. Wrooms creates authenticated Onramp sessions and never exposes signing keys or API secrets to the browser.
Non-custodial routing
Purchased crypto is delivered to a verified compatible wallet controlled by the user. Wrooms does not custody Coinbase purchase funds or purchased assets.
Reviewer test path
Test the production-targeted Wrooms flow
- 1. Open the review page.
This page is public and requires no access code. - 2. Sign in or create an account.
Use the same customer authentication path as production. - 3. Connect a compatible wallet.
Wrooms verifies a destination before the Onramp session can be started. - 4. Open Crypto and choose Coinbase.
Select a supported asset and amount, then continue to Coinbase's hosted flow.
Requested network
Layer 7 (L7)
Wrooms is requesting direct Coinbase Onramp and future Offramp support for Layer 7. Layer 7 is an EVM-compatible mainnet used by the Wrooms ecosystem. Until Coinbase formally exposes L7 through its supported-network APIs, Wrooms only sends Coinbase networks that Coinbase currently reports as supported.

Offer Onramp/Offramp to downstream customers and merchants
Only the Onramp purchase flow is represented as live today. Offramp, merchant, and broader transfer capabilities remain roadmap items until separately implemented and validated.
Authentication
Wrooms authenticates Coinbase CDP requests with short-lived signed JWTs generated server-side. User-facing Wrooms Onramp actions also require an authenticated Wrooms session.
CORS & origin controls
Authenticated write routes use trusted-origin controls. Coinbase CDP requests are server-to-server rather than browser-to-Coinbase API calls.
