Agent Composition Patterns

Single Agent

One agent handles one task end-to-end.

User → Swap Agent → DEX → Result

Agent Chain

Sequential agents form a pipeline.

User → Research Agent → Risk Agent → Trading Agent → Result

Agent Group

Multiple agents collaborate on a complex task.

User → Orchestrator
         ├── Data Agent (market prices)
         ├── Risk Agent (safety check)
         ├── Yield Agent (find opportunities)
         └── Trading Agent (execute)

Autonomous Agent

Self-directed agents with continuous loops.

Loop:
  Monitor → Analyze → Decide → Execute → Log → Sleep → Repeat

Sperax Agent Examples

Agent	Type	Description
USDs Yield Agent	Stablecoin Yield	Hold USDs on Arbitrum, earn 5-10% auto-yield
SPA Staking Agent	Yield Farmer	Stake SPA → veSPA for boosted rewards
Sperax Farm Agent	LP Position	Manage Demeter farming positions
Portfolio Agent	Portfolio Tracker	Track SPA, USDs, veSPA, Plutus positions

ERC-8004 Agents

The ERC-8004 standard enables trustless DeFi agents:

• On-chain registration as NFTs
• Reputation scoring
• Decentralized identity
• Agent-to-agent communication
