Implementation Guide ​

This section provides practical guidance and best practices for implementing the ERC-8004 standard in your applications.

Implementation Resources ​

Agent Metadata Parsing ​

The Agent Metadata Parsing guide covers:

  • Parsing agent metadata structures
  • Handling different metadata formats
  • Validation during parsing
  • Error handling strategies

Onchain Metadata Handling ​

The Onchain Metadata Handling guide provides:

  • Parsing MetadataSet events and empty value handling
  • Three-tier metadata precedence (contract state, on-chain, off-chain)
  • Conflict detection and resolution
  • Error codes for metadata conflicts (WA080, WA081)

Feedback Best Practices ​

The Feedback Best Practices guide provides:

  • Implementation patterns for feedback collection
  • Storage and retrieval strategies
  • Privacy considerations
  • Integration with existing systems

Validation Best Practices ​

The Validation Best Practices guide includes:

  • Implementing validation rules
  • Performance optimization
  • Error reporting
  • Testing validation logic

Getting Started ​

We recommend following this implementation order:

  1. Start with Agent Metadata Parsing to understand data structures
  2. Implement Validation Best Practices to ensure data integrity
  3. Add Feedback Best Practices for user interaction

Each guide includes code examples and common pitfalls to avoid.
