Paybond vs role permissions

RBAC answers who may access which app or API. It is not a funded spend envelope and does not prove tool completion for release or refund.

Focused slice of the comparison matrix for delegated agent spend.

Role permissions comparisonSwipe to compare columns

Dimension	Paybond Kit	Role permissions
Delegation model Who can spend what, under which scope, and for how long.	Capability-scoped intent with bounded budget, allowed operations, and tenant-bound run binding.	Role and permission matrix in your IdP or app; not tied to a funded spend envelope.
Evidence Proof that paid work completed and matches the agreed completion rule.	Signed completion evidence with preset validation, receipts, and ledger provenance.	Access grant and revoke audit trails; no spend outcome proof.
Settlement lifecycle Fund, authorize, execute, release, refund, or hold for review.	Funded intent → authorize tool spend → submit evidence → release, refund, review, or dispute.	Grant or deny access; no monetary settlement path.
Disputes Structured path when outcomes, amounts, or completion disagree.	Built-in dispute cases, evidence export, refund flows, and operator review workspace.	Not provided.
Cross-runtime Same spend controls across agent frameworks and orchestrators.	Tool boundary across OpenAI, Claude, LangGraph, MCP, and custom orchestrators with one policy file.	Centralized identity but not spend-aware at the tool handler.
Secrets exposure Where payment, tenant, and authorization credentials live at runtime.	Capability token bound to intent; tenant ID never taken from unauthenticated tool arguments.	IdP and service secrets; roles do not replace payment credential isolation.
