Key terms used across t54, Trustline, X402 Secure, Claw Credit, XRPL tooling, and research projects.
| Term | Definition |
|---|---|
| Trustline | t54's core agentic risk and underwriting engine. Trustline evaluates evidence, policy, external signals, behavior, and outcomes before or after agent-mediated financial actions. |
| Agentic risk | Risk introduced when an AI agent becomes part of a financial decision loop, including authorization, behavior, counterparty, evidence, credit, and settlement risk. |
| Underwriting | The process of deciding how much financial capacity a user, agent, merchant relationship, or workflow should receive and under what constraints. |
| Liability boundary | The record-based boundary that helps determine responsibility after an adverse agent-mediated financial outcome. |
| Agentic finance | Financial workflows in which agents participate in decisioning, payment, credit, treasury, trading, or settlement activity on behalf of users or institutions. |
| Principal | The real user, developer, organization, or institution on whose behalf an agent is acting. |
| Workflow | A recurring agent-mediated activity pattern, such as API purchasing, card authorization, treasury management, or trading support. |
| X402 Secure | Trustline-powered risk gateway for x402 and AP2-compatible agent payments. |
| Claw Credit | Credit and payment service that gives eligible agents controlled access to x402 services, powered by Trustline underwriting. |
| Consumer finance capability | Trustline extension for agent card underwriting, purchase-plan review, transaction authorization, and outcome feedback for real user financial workflows. |
| Verifiable Intent | Credential-based evidence model for proving delegated user intent and constraints in agent-mediated transactions. |
| AP2 | Agent Payments Protocol model built around intent, cart, and payment mandates for agent payments. |
| Evidence record | A durable record of trace, intent, mandate, payment, signal, or receipt data used to support a Trustline decision. |
| External signal | Third-party or partner intelligence about wallets, entities, sanctions, blocklists, merchant context, or high-risk activity. |
| Universal Subject and Label System | Planned Trustline design direction for organizing subjects, identifiers, links, observations, and decision-grade labels across products. |
| RLUSD Skills | Agent-facing skill and documentation layer for routing RLUSD workflows into the RLUSD CLI runtime. |
| RLUSD CLI | Deterministic command-line runtime for RLUSD operations across XRPL, Ethereum, and supported DeFi workflows. |
| XRPL x402 Facilitator | T54-built facilitator for x402 payments over XRPL using payer-signed XRPL Payment transaction blobs. |
| Agentic Risk Standard | Research project studying event-sourced settlement, escrow, underwriting, and role separation for trustworthy AI agent transactions. |
| Monopoly Simulation | Research environment for studying multi-agent economic behavior and x402 risk control under repeated strategic decisions. |
