Insufficient funds for Solana transaction fee how to fix
You see the error and your wallet shows a balance. The transaction won't send. This is a common Solana problem that has nothing to do with your internet connection or the network being down.
The base fee for a Solana transaction is 0.000005 SOL per signature. That number is misleading. A simple SOL transfer costs that much. Almost nothing else does.
What a real transaction actually costs
A token swap on a DEX like Raydium requires multiple signatures. You pay for the swap instruction, the token transfer, and any associated account checks, so a single swap can consume 0.000015 SOL or more just in base fees.
During network congestion, validators prioritize transactions with additional fees. You can add a priority fee of 0.00001 SOL or higher. Without it, your transaction may never confirm. It will expire and you will not get the base fee back.
NFT mints on Solana often require creating a token account for the new asset. That costs 0.00203928 SOL per Associated Token Account (ATA). This rent is returned when you close the account, but you must have it upfront.
A token transfer to a new recipient also creates an ATA. The real cost of that transfer is the signature fee plus 0.00203928 SOL. Your wallet may not show this clearly.
Why your visible balance can be deceptive
You look at your wallet and see 0.1 SOL. A transaction fails with insufficient funds. This happens when some of that SOL is not freely available.
SOL wrapped in a tokenized form, such as wSOL, does not count toward your fee balance. It exists as a token in a token account, and the network cannot use it for transaction fees. You must unwrap it first.
SOL delegated to a staking pool is also locked. It cannot pay for transactions while delegated. You must undelegate and wait for the cooldown period before those funds become usable.
Your wallet may show your total SOL balance but not separate the free, available portion. The error message is frustrating but accurate.
How to calculate what you actually need
Before any transaction, check three things: the number of signatures required - a swap on Raydium typically uses 2-3 - whether the transaction creates any new token accounts, each one costing 0.00203928 SOL, and current network congestion, since priority fees can increase the total cost by 5-10x during high activity.
A realistic minimum for most DeFi transactions is 0.01 SOL. For NFT mints involving new accounts, 0.02 SOL is safer.
To check your actual available balance, use a Solana block explorer. Look at your wallet address. The "balance" line shows total SOL. The "rent exempt" line shows what is locked in token accounts. Subtract one from the other.
Freeing up SOL from unused token accounts
Every token you have ever received likely created an ATA. Dust tokens from airdrops or failed swaps leave these accounts open. Each holds 0.00203928 SOL of your SOL that you cannot spend.
You can close these accounts. Use a Solana wallet that supports bulk account closure, or use a dApp designed for this. Closing an account returns the rent-exempt SOL to your wallet.
Check the list of your token accounts. Any with a zero balance can be closed safely. Accounts with small balances - under $0.01 worth of tokens - are often not worth keeping. Close them and get your SOL back. After closing unnecessary accounts, your available balance increases and you should see the difference immediately.
A note on this specific token
As of August 31, 2026, Goku super saiyan (GOKU) trades at $0.0003132 and has a market cap of $313,237. Its liquidity is $64,486.96 on Raydium. The token launched on October 26, 2024.
The same fee calculation applies to any GOKU transaction. Token account creation still costs 0.00203928 SOL. The base fee per signature is the same. If your GOKU transaction fails with insufficient funds, the fix is the same regardless of the token: calculate the true cost, check your available balance, and close unused accounts. The token itself does not change the math.
