If you've recovered a wallet using a mnemonic phrase or private key but find your balance displaying zero with a changed address, follow these troubleshooting steps:
1. Incorrect Mnemonic/Private Key Entry
- Double-check for typos or missing characters in your mnemonic phrase/private key.
- Ensure uppercase/lowercase letters match the original (case-sensitive for some blockchains).
2. Correct Mnemonic in Wrong Order
- Mnemonic phrases must be entered exactly in the original sequence. Even one swapped word generates a different wallet address.
3. Original Mnemonic/Key Not Recorded Accurately
- If the mnemonic or private key wasn’t documented correctly during setup, recovery is impossible. Wallet providers cannot access or reset these credentials.
4. Incompatible Wallet Standard
Coin98 Super App supports multiple standards per blockchain. Mismatched standards during recovery will yield a new address.
Examples by Blockchain:
Bitcoin
| Standard | Address Format | Supported By |
|---|---|---|
| Legacy | Starts with "1" (e.g., 1A1Z...) | Exchanges |
| Bech32 | Starts with "bc1" (e.g., bc1z...) | Non-custodial wallets (Trust Wallet, etc.) |
Solana
- New Standard: Recovers Phantom/Sollet wallets with legacy address formats.
- Old Standard: For wallets created pre-update in Coin98 Super App.
EVM Chains (Celo, Avalanche C-chain, TomoChain)
- New Standard: Optimized for EVM-compatible chains using Ethereum-style addresses.
- Old Standard: Legacy wallets within Coin98 Super App.

FAQ Section
Q1: Can I recover funds if I sent tokens to a contract address?
A: No. Transactions to contract addresses are irreversible. Always verify recipient addresses before sending.
Q2: Why was I charged gas for a failed transaction?
A: Gas fees cover network processing effort, regardless of transaction success. This is standard across blockchains like Ethereum.
Q3: How do I ensure my mnemonic phrase is correct?
A: Test it immediately after setup by recovering the wallet in a secure environment before transferring funds.
