Wallet sync errors, like “Sync error (data might be outdated)” or RPC method not found, plague Sui users, especially during high activity or updates. These stem from mismatched chain states, outdated software, or node connection issues, as reported in early 2023. They prevent viewing balances, NFTs, or executing tx, frustrating new adopters. Sui’s object model requires accurate syncing for ownership verification. Step-by-step solution:

1. Update Wallet Software: Enable Developer Mode in Sui Wallet and check for updates. Restart app post-update.
2. Clear Cache and Resync: In wallet settings, clear cache or force resync. Switch RPC endpoints if default fails (use custom like Shinami).
3. Check Network Connection: Ensure stable internet; use VPN if regional blocks. Test on Testnet first.
4. Merge Objects if Needed: Fragmented coins cause sync lags—merge via wallet UI.
5. Switch Wallets: Try alternatives like Ethos or Ledger for comparison.
6. Report and Monitor: If persistent, report on Sui forums. Use explorers for manual checks.
