ONRAMP PARTNER READINESS

API integration preparation · No approval claimed

Clear responsibilities, before integration.

JunleeBuild does not custody customer funds or digital assets. Once integrated, the selected onramp provider performs payment processing, identity verification and KYC/AML; JunleeBuild provides the product experience and secure server integration.

TARGET INTEGRATION

Provider handles payment. Verified events advance product state.

Coverage discovery, checkout and webhook reconciliation remain separated behind server boundaries and stay in sample or sandbox mode until approval.
01

Coverage

Validate country, asset and payment-method support from provider staging data.

02

Quote and checkout

Confirm fees and expected receipt before the provider handles KYC and payment.

03

Server verification

Verify signed webhooks through an idempotent inbox; secrets stay server-side.

04

Separate product consent

An onramp completion never auto-authorizes a support payment or product action.

HOW WE BUILD

Trust architecture, before features.

01

No custody of user assets

Private keys, seeds and customer assets stay with the user.

02

Stop when facts are unclear

Funding, provider responses, policy and account implementation must match before progression.

03

Secrets stay server-side

API keys and webhook secrets stay out of browsers, sample code and public logs.

04

Say only what we proved

Market blueprint, private pilot, staging and R&D are labeled separately. A demo is not settlement.

JAYLINK STUDIO LABS

The lab behind what comes next.

A local studio for validating MCN markets, memberships and digital-content flows without real assets.
