What is DeFAI?
DeFAI is the convergence of decentralized finance and autonomous AI agents. Astarter operates at the execution and settlement layer of this stack.
DeFAI is the convergence of decentralized finance and autonomous AI agents. Binance Research, in its May 2025 DeFAI Unstacked report, defines the category as "the application of autonomous AI agents to DeFi systems" and frames it as "a continuation of crypto's most credible value proposition: disintermediated financial infrastructure."
OKX Ventures positions the same category from the user side. In its February 2025 AI Agent landscape report, DeFAI is the first of eight named sectors, and the rationale is plain: DeFAI "combines the advantages of DeFi and AI, aiming to simplify the complex operations of DeFi, making it easy for ordinary users to utilize these financial tools."
Astarter operates at the execution and settlement layer of this stack — the layer where agents run, transact, and pay each other.
Where Astarter sits in the DeFAI stack
Most DeFAI today is software: an agent framework that runs on someone else's GPU, or a hosted yield strategy that doesn't own the rails it executes on. Astarter integrates both halves of the stack — physical compute below, agent execution above, $AST as the settlement asset between them.
Compute
ABox node operators
Physical hardware running agent workloads
Agent runtime
CORE Agent Layer
Where agents execute, on-chain, deterministically
Settlement
$AST + on-chain contracts
Fees, payments, and agent-to-agent transfers
Applications
AI DEX, Prediction Market, Data Market, Agent App Store
Demand surface for agents to act on
The four layers are described in detail in Architecture and the On-Chain Flywheel.
DeFAI primitives Astarter enables
The standard primitive set is stable across the Tier 1–2 references: Binance Research, OKX Ventures, and Nansen's four-pillar taxonomy (Automated Trading, Risk Management, Yield Optimization, Fraud Prevention). Below, each primitive is mapped to the Astarter product that delivers it.
Autonomous trading agents
Agents that analyze markets and execute trades on-chain
AI-driven yield optimization
Allocating capital across protocols for return, automatically
AI DEX + Agent App Store
Intent-based execution
Users state goals in plain language; agents translate them into on-chain actions
Agent App Store + ABox runtime
Agent-to-agent payments
Machine-to-machine settlement without a human in the loop
$AST + on-chain settlement
Prediction & market making
Pricing uncertainty; providing liquidity to prediction markets
Prediction Market (Use Cases)
Data acquisition
Agents buying, selling, and processing datasets for other agents
Data Market (Use Cases)
Why "Web4 DeFAI"?
The Astarter tagline pairs Web4 — "physical compute infrastructure, autonomous AI, and on-chain settlement converging into a global agent network" (Introduction) — with DeFAI, the financial category these agents operate inside.
Together they describe a specific class of system: one where the AI agent owns its own compute (via ABox), executes on-chain, settles in $AST, and answers to its operator rather than a custodian.
