**Network not appearing in wallet**

- Double-check the Chain ID (8333 for mainnet)
  - Ensure the RPC URL is correct: `https://mainnet-rpc.b3.fun`
  - Try refreshing your wallet or restarting the browser

**Transactions failing**

- Verify you're connected to the correct B3 network - Check that you have sufficient ETH for gas fees - Ensure the
  contract address is valid on B3

**Slow transaction speeds**

- B3 typically processes transactions in 1-2 seconds - If experiencing delays, check the [B3 network status](
  https://status.b3.fun/) - Consider adjusting gas price if needed

**Can't see my tokens**

- Import token contracts manually using the B3 Explorer
  - Ensure you're viewing the correct network in your wallet
  - Some tokens may need to be manually added to your wallet's token list

Always verify that users are connected to the correct B3 network before executing transactions. The Chain ID for B3
  Mainnet is 8333.
