What is SumSub?

SumSub is Node Proptech's KYC, AML, and identity verification partner, responsible for:

Performing investor identity checks,

OFAC and PEP screening

Accreditation verification

with compliance status encoded as a soulbound ERC-721 token bound to each verified wallet.

How SumSub Performs Identity Verification

SumSub executes the identity verification process that every investor must complete before participating in a Node offering. This includes:

Document verification (government-issued ID, proof of address)

Biometric checks (liveness detection, facial matching)

Database screening against sanctions lists

Politically exposed persons databases.

The verification is not a one-time event. SumSub performs ongoing monitoring, re-screening investors against updated sanctions lists and adverse media databases as required by jurisdiction and policy.

The identity verification process is not about making it hard for investors. It is about meeting regulatory requirements and building investor protection. SumSub collects the documentation it needs, verifies identity with reasonable confidence, and encrypts sensitive data. This continuous monitoring model reflects the AML obligations that apply to regulated securities offerings.

OFAC, PEP, and Sanctions Screening

These screens are required, not optional. A platform that does not perform OFAC screening exposes itself to regulatory action and potential criminal liability. SumSub's screening services handle this obligation professionally, making it part of the standard onboarding process without making it burdensome for compliant investors.

Every investor and wallet that enters the Node ecosystem is screened against the U.S. Office of Foreign Assets Control sanctions list. SumSub also identifies politically exposed persons, individuals who hold or have recently held prominent public positions and are subject to enhanced due diligence under anti-money laundering rules.

These screens are executed at onboarding and on an ongoing basis. If an investor's status changes, SumSub flags the account for review. This is a regulatory requirement for any platform operating under Reg D 506(c) with verified accredited investors.

On-Chain Compliance Encoding

The soulbound token is the innovation that enables on-chain compliance automation. Without it, compliance checks would require centralized review of every transaction. With the token, the smart contract reads the compliance status and makes compliance decisions without human intervention.

This is a genuine efficiency gain that benefits investors through faster transactions and lower operational costs. Once SumSub verifies an investor's identity, accreditation, and jurisdictional eligibility, that compliance status is encoded as a soulbound ERC-721 token bound to the investor's verified wallet. This token is non-transferable. It cannot be sold, delegated, or moved to another wallet. It functions as an on-chain credential that the smart contract layer checks before permitting any transaction.

Instead of a compliance officer manually approving each transfer, the smart contract reads the soulbound token, confirms the wallet's eligibility, and permits or blocks the transaction automatically.

SumSub at Node Proptech

SumSub occupies the identity and eligibility verification position within the Node institutional partner stack. It works alongside:

S&K (legal structuring)

Ocorian (SPV administration)

Securitize (transfer agent),

Forvis Mazars (audit).

SumSub's output, the verified identity and the soulbound compliance token, is the prerequisite that unlocks access to everything else in the Node ecosystem.
