Error Handling in Drops Bot: Common Issues & Solutions

When using blockchain-based features like swaps, liquidity tracking, and smart contract interactions, errors may occur due to various factors. Here's a detailed breakdown of the most common errors, their causes, and how to resolve them.

1. Slippage Control

Error

“Failed due to ‘executing swap was failed on the blockchain. Reason: Exceeds desired slippage limit’”

📍 Cause

Your slippage tolerance is set too low. The actual market price changed more than your allowed slippage.

💡 What is Slippage?

The difference between the expected execution price and the actual price when the transaction goes through. It helps protect users from volatile market moves.

✅ Solution

Increase the slippage tolerance in settings to allow successful transaction execution during market volatility.

2. Solana Fee Reserve Required

Error

“Failed due to 'Balance is not enough to transfer and cover Solana fees’”

📍 Cause

Insufficient SOL balance to cover transaction fees.

✅ Solution

To successfully execute transactions, you need to have an additional 0.01 SOL in your account as a reserve. These funds are intended to cover any unexpected issues that may arise during the transaction process.

3. Account is Frozen

Error

“Executing swap was failed on the blockchain. Reason: account is frozen”

📍 Cause

The wallet contains suspicious or unauthorized tokens, triggering a "frozen" status on-chain.

✅ Solution

• Check your wallet's token list

• Remove suspicious or unknown tokens

• Avoid manually adding unchecked tokens

• If compromised, create a new wallet and transfer safe assets only

🔒 Recommendation

Use tools like Token Sniffer, DexTools, or CoinGecko to verify token safety before interacting with them.

4. Invalid Recipient Address

Error

“Failed due to ‘there was an error while executing transfer’”

📍 Cause

Issues with the recipient address:

• Incorrect format

• Wrong network

• Non-existent or inactive wallet

✅ Solution

• Double-check the address format (should start with 0x and be 42 characters for EVM chains)

• Make sure it belongs to the correct network

• Avoid addresses copied from untrusted sources

5. Failed to Build Swap Route

Error

“Failed due to ‘failed to build swap route details’”

📍 Cause

The swap aggregator (e.g., Jupiter) cannot find a route between the selected tokens due to:

• Lack of liquidity

• No available pool

• Unsupported or unknown token

• Transaction amount too large/small

✅ Solution

• Use Jupiter manually to explore possible routes

• Lower the swap amount

6. Transaction Not Confirmed

Error

“Failed due to ‘tx (tx hash) was not confirmed, please try to increase fee or contact support’”

📍 Cause

• Low priority fee

• Network congestion

✅ Solution

• Increase the Priority Fee in DropsBot settings

• Retry the transaction with a higher fee

• Monitor network load before sending important transactions

7. General Processing Error

Error

“There was an error while processing transaction”

📍 Cause

A generic failure due to:

• Blockchain/network issues

• Smart contract errors

• Insufficient funds

• Invalid input or swap parameters

• Router malfunctions

✅ Solution

• Retry the transaction — sometimes it’s a temporary issue

• Ensure sufficient balance for gas

• Recheck all inputs (token pairs, values, routes)

• Wait and confirm network stability

✅ General recommendations:

• Avoid interacting with unverified tokens

• Check liquidity and swap routes in advance

• Monitor network congestion

• Use only trusted wallets and addresses

• If you encounter suspicious errors — recreate your wallet and transfer assets manually
