## Validation

All token lists are validated against:

- Uniswap Token Lists JSON Schema
- EIP-55 address checksumming
- Chain ID strict validation (must be 138)
- Duplicate detection (addresses and symbols)
- Logo URL accessibility
- On-chain contract verification

### Running Validations

```bash
# Full validation
node scripts/validate-token-list.js lists/dbis-138.tokenlist.json

# Check address checksums
node scripts/checksum-addresses.js lists/dbis-138.tokenlist.json

# Fix checksummed addresses
node scripts/checksum-addresses.js lists/dbis-138.tokenlist.json --fix

# Validate logos
node scripts/validate-logos.js lists/dbis-138.tokenlist.json

# Verify on-chain
node scripts/verify-on-chain.js lists/dbis-138.tokenlist.json
```

---

## CI/CD

### PR Validation

GitHub Actions automatically validates token lists on pull requests:

- JSON schema validation
- Address checksum validation
- Duplicate detection
- Logo validation (non-blocking)
- On-chain verification (optional, non-blocking)

### Release Process

1. Update version using release script:
   ```bash
   ./scripts/release.sh patch  # or minor, major
   ```

2. Create git tag:
   ```bash
   git tag -a v1.2.0 -m "Release v1.2.0"
   git push --tags
   ```

3. GitHub Actions release workflow will:
   - Run all validations (required)
   - Perform on-chain verification (required)
   - Generate checksums
   - Sign token list
   - Create GitHub Release

## Security

### Signature Verification

Token lists are signed with minisign for integrity verification:

# Verify signature
minisign -V -p minisign.pub -m lists/dbis-138.tokenlist.json -x lists/dbis-138.tokenlist.json.sig
```

### Public Key

The public key is included in the repository: `minisign.pub`

Private key is stored securely in GitHub Secrets for CI/CD signing.

2. Ensure token meets inclusion requirements
3. Code owners review and approve
4. Validations run automatically via CI/CD

### Updating Tokens

1. Update token metadata in `lists/dbis-138.tokenlist.json`
2. Run validations locally
3. Create pull request
4. CI/CD validates changes

### Removing Tokens

1. Create issue explaining removal reason

## Dependencies

- Node.js >= 16.0.0
- pnpm (package manager)
- `@uniswap/token-lists` (official Uniswap Token Lists package)
- ethers.js (for address validation and on-chain verification)
- ajv & ajv-formats (for JSON schema validation)
- minisign (for signing, optional for verification)

Install dependencies:

```bash
pnpm install
```

### Package Integration

This project uses the official `@uniswap/token-lists` package for:
- JSON Schema validation
- TypeScript type definitions
- Specification compliance

The validation scripts automatically use the package schema, with fallback to URL fetch if the package is unavailable.
