External Signals
Trustline can incorporate wallet, entity, sanctions, and counterparty intelligence into risk and underwriting decisions.
External signals help Trustline understand risk that cannot be inferred from an agent trace or payment request alone. A transaction may look reasonable from the agent's reasoning, but the destination wallet, merchant, or entity may have a high-risk history. Conversely, a new agent action may become more acceptable when strong external evidence supports the counterparty.
Trustline's external signal framework is designed as a provider-agnostic layer. It can ingest results from blockchain intelligence providers, entity intelligence systems, blocklists, sanctions data, and other partner sources. The first design target is wallet and counterparty risk, with room to support additional providers as product needs expand.
External signals are especially important for institutional workflows because liability often depends on what was knowable at the time of decision. If a wallet was associated with high-risk activity, if a merchant was newly created, or if a sanctions or blocklist result was available, that information should be visible to the underwriting layer before the transaction moves. Trustline treats external intelligence as decision evidence, not as a detached dashboard metric.
Signal Types
| Signal type | Example use |
|---|---|
| Wallet risk score | Inform payment approval, review, denial, or underwriting capacity. |
| Sanctions or blocklist hit | Trigger automatic decline or partner-specific escalation. |
| High-risk activity tag | Identify exposure to scams, mixers, exploit funds, or abusive patterns. |
| Entity metadata | Add merchant, exchange, protocol, or service context. |
| Provider confidence | Preserve uncertainty rather than treating every result as equally reliable. |
External signals are not meant to replace Trustline's own underwriting logic. They are additional evidence. A provider result can strengthen, weaken, or block a decision depending on policy, confidence, and product context.
Decision Use
In validation workflows, external signals can act as pre-checks. A sanctions hit, blocklist match, or very high wallet risk can cause a request to be denied before further processing. Medium-risk signals may trigger review or require stronger evidence.
In underwriting workflows, external signals can affect capacity. A user, agent, merchant relationship, or institutional workflow may receive lower limits when counterparty risk is elevated. Strong external confidence can also support higher capacity when other signals align.
Audit And Provider Boundaries
Every external lookup is designed to be auditable. A decision record preserves which provider was used, what check type was performed, when the lookup occurred, and which normalized signals influenced the decision. Raw provider data may be stored or restricted depending on policy, while the decision remains explainable to the downstream product.
Trustline is not tied to a single provider. Provider coverage, scoring, and data quality can change over time. The durable part of Trustline is the normalized signal interface and the policy layer that decides how those signals affect agentic finance workflows.
