3. **Contract Standards**
   - ERC-20 tokens must implement standard ERC-20 interface
   - Oracle feeds must implement Chainlink-compatible interface
   - All functions (decimals, symbol, name, etc.) must be callable

4. **Metadata Accuracy**
   - `decimals`, `symbol`, and `name` must match on-chain values
   - Address must be EIP-55 checksummed
   - Logo URL must be accessible and return valid image

5. **Security**

   - Public security audit reports preferred
   - Links to audit reports should be provided

2. **Upgradeability**
   - Immutable contracts preferred
   - If upgradeable, admin keys and upgrade process must be disclosed

## Governance Process

### Adding Tokens

1. **Request Submission**
   - Create issue or pull request with token details
   - Include contract address, metadata, and verification evidence
   - Provide links to audits, documentation, or verification

2. **Review Process**
   - Code owners review submission
   - On-chain verification performed
   - Security assessment (if applicable)

3. **Approval**
   - Requires approval from at least one code owner
   - All validations must pass
   - Version bump (minor for additions)

### Removing Tokens

1. **Delisting Request**
   - Create issue explaining reason for delisting
   - Provide evidence (exploit reports, legal notices, etc.)

2. **Review Process**
   - Code owners review delisting request
   - Verify claims and evidence
   - Consider impact on users

3. **Execution**
   - Requires approval from at least one code owner
   - Version bump (major for removals)
   - Update CHANGELOG.md with reason

## Versioning Policy

Token list versions follow semantic versioning:

- **Major** (x.0.0): Token removals, breaking changes
- **Minor** (x.y.0): Token additions
- **Patch** (x.y.z): Metadata fixes (name, symbol, logo), no address changes
