# Common Reasons for Transaction Failure

If a transaction fails, users are advised to **check** the following settings first:

* **Slippage tolerance**
* **Priority fee**
* **Anti-sandwich mode**

***

### ⏱ 1. Timeout Failures

A timeout failure may occur for several reasons:

* **Low priority fee** – When the fee is too low, the transaction takes longer to be processed by validators, often leading to timeouts after the countdown expiration.
* **Low slippage** – If the token price fluctuates sharply (e.g., during candle wicks or volatile periods), the transaction may fail to trigger within the set tolerance.

***

### ⚙️ 2. Submission or Execution Failures

#### (1) **Manual / Limit Orders – Submission Failed (Not On-Chain)**

* **Insufficient wallet balance** — When your wallet lacks enough ETH/SOL to cover both the purchase and gas fees.\
  💡 *Tip: Keep at least 0.02 SOL available in your Solana wallet for smooth trading.*
* **Insufficient token balance when selling** — The transaction cannot be submitted if you do not hold the token.
* **Buy submission failed** — Some tokens restrict early purchases during the project’s initial phase.
* **Sell submission failed** — The project may be a **honeypot**, or your address may be **blacklisted**, preventing sales.

***

#### (2) **Manual / Limit Orders – Execution Failed (On-Chain)**

* Usually caused by **low slippage tolerance**.\
  Even though the transaction is submitted on-chain, execution fails — consuming **gas and/or priority fees**.\
  💡 *Tip: When trading new or highly volatile tokens (e.g., during FOMO phases), increase your slippage tolerance.*

***

#### (3) **No Available Route (Not On-Chain)**

* The token’s **liquidity pool has been removed** by the creator or project team, making trading routes unavailable.
* For tokens created on **Solana platforms** such as *Pump.fun* or *Moonshot*, if the token’s market cap has reached around **$45K** and the team is still **adding liquidity to Raydium or Meteora DEX**, trading will be temporarily unavailable.\
  💡 *Please wait until the pool is live before attempting to trade again.*
