01
Intent
intent.igra
Defines the objective, scope, constraints and desired economic outcome.
Core question
What should happen?
Axiom Reference Model
The Economic Lifecycle of an Autonomous Transaction
Different implementations. One shared economic language.
Different implementations.•Same economic meaning.
The model
Seven responsibilities. One complete economic flow.
Axiom describes economic meaning, not software architecture. The Reference Model separates economic responsibilities from technical implementation. A protocol may realize these responsibilities through smart contracts, APIs, covenants, payment networks or any combination of execution environments.
Semantic Namespace
The .igra namespace provides stable names for the semantic primitives defined by the Axiom Reference Model.
It is independent of any specific blockchain, virtual machine or execution environment and does not imply implementation dependencies.
Different protocols may realize these responsibilities through different technical architectures while expressing the same underlying economic meaning.
02
Authorization
auth.igra
Establishes who may act, under which permissions, limits and mandates.
Core question
Who is allowed to act?
03
Information
data.igra
Supplies the trusted context, metadata and evidence needed for a decision.
Core question
What does the agent know?
04
Escrow
escrow.igra
Reserves economic value under explicit conditions until obligations are fulfilled, and governs release, refund or dispute resolution when those conditions are contested or unmet.
Core question
How is value secured?
05
Payment
pay.igra
Moves value according to the agreed rules, budget and recipient structure.
Core question
How does value move?
06
Settlement
settle.igra
Finalizes the economic outcome and establishes the authoritative economic state.
Core question
When is it final?
07
Audit
logs.igra
Records actions, decisions and outcomes so every transaction remains verifiable.
Core question
How can it be verified later?
Architectural principle
Smart contracts describe execution.Axiom describes economic meaning.Execution environments may differ. Economic responsibilities remain stable.
The model does not prescribe a blockchain, virtual machine, logic zone or protocol. It provides a stable semantic vocabulary for describing, comparing, composing and documenting autonomous economic systems across different execution environments.
Why it matters
A common semantic vocabulary makes different protocols easier to describe, compare and analyze.
x402, ERC-8183, card networks, covenant-native applications and other implementation environments may differ radically in implementation while still expressing many of the same economic responsibilities through different technical designs.
Compare
See where protocols align and diverge.
Compose
Reason about how economic responsibilities compose across different implementations.
Communicate
Provide builders, researchers and architects with a shared semantic vocabulary.
