Broker & Market-Maker Onboarding

What we need to onboard your firm as a liquidity provider or API trader on BlankFX.

Broker & Market-Maker Onboarding

To trade on BlankFX — providing RFQ liquidity or trading over the API — your firm goes through a one-time onboarding review. This page is the complete list of what we need; send it all in one package and we’ll come back with anything missing rather than drip-feeding requests.

This is standard institutional-crypto onboarding (KYB), sized for a firm our stage can actually turn around quickly, not a bank’s compliance program.

How much we ask depends on how you settle. Most BlankFX flows settle on-chain and atomically — where that’s true, our exposure to your firm is small and the checklist stays light. Delayed-settlement or credit-bearing flows carry real counterparty exposure, which is why the financial section below only applies to those.

What to send

Corporate (KYB)

Item	Notes
Certificate of incorporation + registry extract	Recent
Constitutional document	Memorandum/articles or local equivalent
Ownership chart to UBOs ≥ 25%	Plus ID for each owner and director
Proof of registered/operating address	Recent
Authorized signatory evidence	Board resolution or equivalent naming who may bind the firm for trading

Regulatory & compliance

Item	Notes
Licenses/registrations	Where your activity requires one — or a signed statement that none is required, naming the jurisdiction
AML confirmation	Confirmation you run an AML program appropriate to your business + your compliance contact. Firms trading only their own capital: a short statement of that fact is enough
Sanctions declaration	No ownership/control by sanctioned persons, no operations in comprehensively sanctioned jurisdictions, consent to ongoing screening
Litigation & enforcement	Anything material in the past 5 years, or a statement that there is none

Financial — delayed-settlement / credit-bearing flows only

Atomic settlement

If you only trade atomically-settled flows, skip this section entirely — we set a conservative default exposure cap instead.

Delayed settlement

Item	Notes
Latest financial statements	Audited if available; management accounts are fine for younger firms
Source of trading capital	Short statement — own capital, investor capital, or borrowings
Capital adequacy	Confirmation of unencumbered capital comfortably above your requested exposure cap

Operational & technical

Item	Notes
Settlement wallet address(es)	Each proven by signing a challenge message we provide
Named traders & key custodians	Who holds the API keys; keys are per-firm, never shared with sub-clients
Key management description	Where API/private keys live — HSM, MPC custodian, encrypted store
Ops & incident contacts	Trading-hours contact; 24/7 contact required for delayed-settlement flows
Expected activity profile	Pairs, typical clip sizes, expected daily volume — calibrates your limits, not a commitment

Agreements

Item	Notes
Signed liquidity-provider / trading agreement	Incorporates our API Terms and Prohibited Use Schedule
Fee/spread schedule acknowledgment	Countersigned term sheet

What we don’t ask for: bank references, notarized/apostilled documents (plain copies + a video call if we have identity doubts), proof-of-reserves of your firm, exclusivity, or volume minimums to get onboarded.

What happens after you submit

1. Submit your package

   Send everything above in one email, noting whether you expect atomic or delayed-settlement flows.

2. Independent verification

   Registry lookup of your entity, sanctions/adverse-media screening, on-chain history of your settlement wallets, and a license check against the relevant regulator’s public register.

3. Test trade

   A small supervised test trade before we raise your limits.

4. Decision

   Roughly 1–2 weeks from a complete package; longer for firms needing enhanced review.

After you’re onboarded

• Tell us before settling from a new wallet — unannounced addresses are rejected, not investigated after the fact.
• Notify us promptly of: a change of control or beneficial owners, loss of a relevant license, regulatory action against you, a key compromise, or insolvency events.
• We re-screen registry and sanctions status annually, and do a full refresh every couple of years.
