When attempting to perform a swap on Trust Wallet, users may encounter the error message: Swap is blocked by asset tax value

This indicates that the token in question has an "unknown" tax value. Trust Wallet blocks such swaps for security reasons, ensuring that users avoid potential losses from unverified token taxes. Let’s dive deeper into what this means and how you can work around it.

What Is Asset Tax Value?

In the world of decentralized finance (DeFi), some tokens apply taxes on transactions. These taxes, known as Buy Tax and Sell Tax, are fees deducted during swaps or transfers. For instance, when you attempt to swap a token, a percentage of the token's value may be deducted as tax.

Trust Wallet uses GoPlus to fetch this tax information for tokens. If the tax values are unavailable or marked as “unknown,” swaps involving those tokens are blocked in the app to safeguard users from unexpected deductions.

Why Is My Swap Blocked?

Trust Wallet’s In-App Swap feature supports ERC20 tokens for ETH, BEP20 tokens for BNB, and other supported routes. However, not all token pairs are available for direct swaps.

Key Reasons:

1. Unknown Tax Value: The token’s tax information is unavailable.
2. Unsupported Swap Pair: The token pair isn’t supported on Trust Wallet.
3. Insufficient Liquidity: The liquidity required for the swap is unavailable.
   
   
   

Resolving the Swap Error

If your token swap is blocked, here’s what you can do:

1. Check the Token on GoPlus

• Visit GoPlus and search for your token by putting the contract address and blockchain there.
• Look for Buy Tax and Sell Tax in the results.
• If these values are "unknown," Trust Wallet will block the swap.

2. Use External Platforms

• Check CoinMarketCap or CoinGecko to find where the token is traded.
• Transfer your tokens to a compatible centralized exchange (CEX) or decentralized exchange (DEX) to complete the trade.

3. Manual Conversion

• Use bridges or third-party tools to exchange the token indirectly.

Frequently Asked Questions

• What does “unknown tax value” mean?
  It means the token’s tax information is not verified. Trust Wallet blocks swaps to prevent unexpected losses.

• Why aren’t all swap pairs supported?

  Trust Wallet supports only certain tokens and pairs for secure transactions.

• How can I swap unsupported tokens?
  Use DEXes or CEXes listed on CoinMarketCap or CoinGecko.

• Does the block mean my token is unsafe?
  Not necessarily. It only indicates the tax data is unavailable. Verify token safety on GoPlus or community platforms.
