Glossary: Linked Wallet Addresses

What are linked wallet addresses?

Linked wallet addresses are addresses grouped through an explicit connection or an inference method. Record the linkage source and confidence; shared contracts, exchanges, and custodial services can make common activity misleading.

Why address linkage matters

One user may use several wallets, accounts, or chains. Without a documented linking rule, analytics can count those addresses separately or mistakenly combine unrelated activity. Address linkage can support audience analysis, deduplication, and cross-chain views, but it also raises accuracy and privacy considerations.

Example

A user connects two wallets to the same product account and explicitly links them. A profile may show both addresses under that account. If a provider instead infers a cluster from behavioral signals, that result should be labeled as inferred and evaluated with its confidence and limitations.

Using linked addresses

Record whether the relationship is user-provided, session-based, entity-labeled, or algorithmically inferred. Preserve the underlying addresses and provenance, define when links can be removed or updated, and avoid using uncertain clusters as verified personal identities.

Common mistakes

• Assuming common funding or transaction patterns prove shared ownership.

• Combining contracts, exchanges, bridges, and individuals without separating entity types.

• Comparing wallet counts from different clustering methods as if they were equivalent.

FAQs

Are linked addresses always controlled by one person?

No. An inferred relationship is not proof of common ownership. Linkage signals and confidence vary, and addresses can represent contracts or shared services.

How are wallet addresses linked?

Possible signals include explicit user-provided connections, shared session context, or provider-specific clustering. The basis and confidence should be documented.

How is this different from identity resolution?

Linked addresses describe a relationship among blockchain addresses; identity resolution may combine web, app, and wallet signals into a broader profile.
