Datai × ChainComply: Adding On-Chain Financial Context to Crypto Compliance Investigations

Datai provides ChainComply with DeFi portfolio data and transaction context enrichment, helping its crypto Enhanced Due Diligence platform interpret complex on-chain activity for Source of Wealth and Source of Funds investigations.

About ChainComply

ChainComply provides crypto Enhanced Due Diligence software for banks and financial institutions. Its platform helps compliance teams investigate clients’ crypto activity, reconstruct Source of Wealth (SoW) and Source of Funds (SoF), analyze wallets and transactions, and generate auditable compliance reports.

That challenge is increasingly relevant for traditional finance. When a client transfers significant funds from the crypto ecosystem into a bank, compliance teams need to understand where those funds originated and how the client’s wealth was generated.

The investigation can span centralized exchanges, self-custodial wallets, and DeFi protocols. ChainComply consolidates this into a unified investigation workflow — reducing a process that would otherwise require extensive manual reconciliation and specialist blockchain expertise.

Its platform supports wallet and account analysis, funds-flow investigation, counterparty analysis, sanctions screening, current wealth analysis, and audit-ready reporting.

The challenge: understanding what is actually happening on-chain

Raw blockchain data alone does not provide the financial context a compliance investigator needs.

A wallet may hold assets deployed across multiple DeFi protocols — not only tokens sitting directly in the wallet. And a transaction between an address and a smart contract does not, by itself, explain the economic activity behind that movement.

Was the client transferring funds to another party? Swapping one asset for another? Depositing into a lending protocol? Providing liquidity? Interacting with an NFT application? Or interacting with a scam or spam asset?

That distinction matters when reconstructing a client’s financial history.

Without enough context, known DeFi interactions can look like unexplained asset movements — while spam and scam-token activity can introduce irrelevant or misleading noise into a wallet history. ChainComply therefore needs more than blockchain records. It needs structured information that helps explain the financial activity behind them.

Datai’s role: an on-chain financial context layer

ChainComply integrates Datai across two complementary areas.

1. DeFi portfolio

Datai’s DeFi Positions API powers the DeFi holdings component of ChainComply’s portfolio analysis.

Rather than limiting the view of a client’s wealth to assets held directly in a wallet, Datai identifies and structures positions deployed across supported DeFi protocols.

This gives ChainComply additional visibility into a client’s on-chain portfolio and allows DeFi exposure to become part of the broader wealth picture presented to the compliance investigator.

2. Transaction context enrichment

For transaction investigations, Datai acts as a context enrichment layer.

ChainComply consolidates transaction histories as part of its wider investigation workflow. Datai adds another layer by classifying and contextualizing on-chain activity.

At the foundation of this capability are Datai’s smart-contract catalogs and labels. By identifying the protocols and applications behind smart-contract interactions, Datai can recognize the context of activities such as swaps, lending, liquidity provision, NFTs, and other on-chain interactions.

This smart-contract intelligence feeds Datai’s transaction classification engine — transforming technical blockchain interactions into structured financial context:

ChainComply uses these contextual signals to enrich transaction and wallet analysis, helping investigators distinguish known on-chain financial activity from movements that require further review.

One concrete example is scam and spam activity. ChainComply uses Datai’s Scam classification as its primary spam/scam signal in client wallet analysis — helping identify scam-token activity that could otherwise introduce misleading transactions or values into a compliance investigation.

The Scam classification is one application of the broader enrichment layer: Datai provides additional context about what happened on-chain; ChainComply incorporates those signals into its own compliance analysis.

From blockchain activity to compliance intelligence

The collaboration creates a clear separation of roles:

Datai does not determine whether a client’s activity is compliant or suspicious. It helps make the underlying blockchain activity more understandable.

ChainComply combines that context with the other information and risk intelligence in its platform to perform the compliance investigation and produce the output required by the financial institution.

“Blockchain transparency does not automatically make blockchain activity understandable,” said Elie Azzi, CEO of Datai. “A compliance application needs to know not only that a transaction occurred, but what that transaction represents financially. Our role is to provide that interpretation layer — reconstructing DeFi positions and adding context to smart-contract interactions — so that platforms such as ChainComply can build this intelligence into institutional financial workflows.”

“Datai gives us additional visibility into what is actually happening inside a client wallet. Its DeFi data helps us build a more complete portfolio picture, while its transaction classifications provide useful context for our investigations — including the scam classification we use to identify spam and scam-token activity,” said Lukasz Lukaszewski, Co-Founder and CPO of ChainComply.

The outcome: richer investigations without rebuilding on-chain intelligence

By integrating Datai, ChainComply can incorporate deeper on-chain financial context into its product without independently building and maintaining the protocol-specific data infrastructure required to interpret DeFi positions and smart-contract interactions.

For ChainComply’s users, this contributes to a more complete view of a client’s crypto activity:

• Greater visibility into DeFi holdings, extending portfolio analysis beyond directly held wallet assets
• More context around transactions, helping explain the financial activity behind smart-contract interactions
• Better identification of irrelevant or misleading activity, including scam and spam-token interactions
• More interpretable wallet histories for Source of Wealth and Source of Funds investigations

This supports ChainComply’s broader objective of making complex crypto investigations accessible to traditional compliance teams — a bridge that helps banks coexist with the crypto ecosystem.

What this means for Datai

The ChainComply integration illustrates a broader role for Datai’s infrastructure.

Blockchain applications generate transparent data — but transparency alone does not make that data financially understandable. DeFi positions need to be reconstructed. Smart contracts need to be identified. Transactions need to be interpreted in the context of the applications users interact with.

Datai provides this interpretation layer.

For ChainComply, that intelligence becomes an input into crypto compliance investigations. In other applications, the same standardized on-chain financial data can support portfolio reporting, accounting, asset management, and other institutional workflows.
