Partner application preparation

PARTNER READINESS

Clear roles and responsibilities before integration.

JunleeBuild makes no claim of an unapproved relationship or live API. We prepare legal-entity information, zero-custody data flow, a sandbox-first implementation plan and operational stop conditions for provider review.

DUE DILIGENCE

A review pack built for diligence

01

Legal entity and accountable owner

Clearly disclose the Korean legal entity, CEO, incorporation date, address and official contact channel.

02

Specific product use case

Describe target users, market, user-owned wallet destination and the post-on-ramp product action separately.

03

Zero-custody data flow

Show boundaries for fiat and KYC responsibility, provider checkout, wallet delivery, separate consent and downstream verification.

04

Server-only credentials

API keys and webhook secrets belong in a managed secret store and stay out of browsers, source, logs and sample UI.

05

Sandbox-first verification

Validate supported assets, payment methods, quotes, transaction sessions and webhook states in staging before separate live approval.

06

Fee and availability disclosure

Users confirm fees, expected receipt, KYC, payment method and regional eligibility from provider-supplied data.

07

Stop, retry and support

Define idempotency, verified event inbox, fail-closed stop, incident owner and support path before live activation.

Current application boundary

The current stage is application preparation. No on-ramp company name, logo, contract, approval, API access or production availability is claimed.
