Check for 0x prefix\n2. Validate hex characters\n3. Verify checksum (EIP-55 for mainnet)\n4. Show error for invalid addresses\n\n## Acceptance Criteria\n- [ ] Valid addresses accepted\n- [ ] Invalid format rejected with message\n- [ ] Checksum validation for mainnet\n- [ ] Test with various address formats\n\n## Technical Notes\n**File:** src/screens/CryptoPaymentScreen.tsx:107\n**Functions:** Add address validation utility\n\n## Constraints\n- Must handle testnet addresses\n- Consider mixed case addresses\n- Performance for real-time validation","closed_by":null,"reactions":{"url":"https://api.github.com/repos/Smartdevs17/SubTrackr/issues/35/reactions","total_count":0,"+1":0,"-1":0,"laugh":0,"hooray":0,"confused":0,"heart":0,"rocket":0,"eyes":0},"timeline_url":"https://api.github.com/repos/Smartdevs17/SubTrackr/issues/35/timeline","performed_via_github_app":null,"state_reason":null,"pinned_comment":null}
