A Creator's Guide to Improving Smart Contract Bugs
Smart contract bugs can derail a token launch, drain liquidity, and destroy creator credibility. This guide provides a structured approach for creators to systematically identify and address vulnerabilities in their token contracts before launch. We focus on practical steps, common pitfalls on platforms like Solana, and how a secure foundation impacts long-term holder trust.

Why Smart Contract Bugs Are a Token Creator's Biggest Risk
A bug can erase your token's value before your first major marketing push.
For a token creator, a smart contract bug isn't just a technical flaw—it's a direct threat to the project's economy and reputation. A single vulnerability can lead to unlimited minting, frozen funds, or stolen liquidity, often resulting in a 100% loss for early supporters. While platforms like Ethereum have a long history of costly exploits, Solana's speed and lower costs mean bugs can be exploited in milliseconds, leaving little time to react. The verdict is clear: investing time in bug improvement before launch is non-negotiable for sustainable success. A secure contract is the foundation for the 0.30% creator revenue and ongoing holder rewards that platforms like Spawned facilitate.
4 Most Common Smart Contract Bug Categories for Tokens
Focus your review on these high-impact areas. Catching these early prevents the majority of post-launch crises.
- Access Control & Ownership Flaws: The most critical. Who can mint new tokens? Who can pause trading or change fees? On Solana, incorrectly configured mint or freeze authorities are a frequent source of exploits. A template from a launchpad like Spawned pre-defines these roles securely.
- Integer Overflow/Underflow: While less common with newer Solidity/Solang versions, math errors in buy/sell tax calculations, reward distributions, or vesting schedules can corrupt tokenomics. For example, a 1% buy tax calculated incorrectly could take 100% of a trade.
- Reentrancy & Logic Race Conditions: On Solana, similar risks exist with Cross-Program Invocations (CPIs). If your token contract interacts with a liquidity pool or staking program, ensure state changes happen before external calls to prevent recursive exploits.
- Oracle & Price Feed Manipulation: If your token's function relies on external price data (e.g., for collateralized rewards), a stale or manipulated feed can be gamed. Using multiple, reputable sources is key.

Special Considerations for Improving Solana Token Contracts
Solana's architecture introduces unique bug risks. The high throughput and low fees mean exploits can happen in a single block. Pay extra attention to:
- Account Validation: Every Solana instruction must validate the accounts passed to it. Failing to check that a provided token account belongs to the expected mint is a common error leading to stolen funds.
- Compute Unit Limits: Transactions can run out of compute units. Your contract must handle partial execution gracefully or ensure critical state changes happen early in the logic.
- Token-2022 Program: If you plan to use advanced features like transfer fees (like Spawned's 1% perpetual post-graduation fee), ensure you are using the correct
spl_token_2022library and your contract logic is compatible. Misconfiguration here can lock tokens permanently.
Using a launchpad that abstracts this complexity, like Spawned's AI builder, can prevent these architectural missteps by providing pre-configured, tested contract modules.
Bug Risk: pump.fun vs. A Structured Launchpad Approach
Your launch platform choice directly impacts your exposure to contract bugs.
| Aspect | pump.fun (Bonding Curve) | Spawned (Structured Launchpad) |
|---|---|---|
| Contract Source | Standard, closed bonding curve contract. Custom token contract is minimal. | Provides customizable but audited token contract templates for your specific use case. |
| Creator Control | Very limited. You cannot add custom tax logic or secure functions post-launch. | You control and can review key parameters like fees (0.30%/0.30%) and access controls before launch. |
| Bug Surface Area | Low for the token itself, but all risk is concentrated in the shared bonding curve contract (a systemic risk). | Managed through provided templates. Your review focuses on your specific customizations, not the entire foundation. |
| Post-Launch Flexibility | None. Graduation is a full migration. | Uses Token-2022 for advanced features, allowing for secure, upgradeable fee structures like the 1% perpetual fee. |
The key difference: pump.fun offers simplicity but transfers systemic risk to the creator. A structured approach gives you the tools and responsibility to build a secure, bespoke contract from the start.
What to Do If a Bug Is Found After Launch
Despite best efforts, bugs happen. A prepared response can save your project.
- Immediate Assessment: Determine the bug's impact. Is it actively being exploited? Can it be triggered accidentally? Pause trading via contract function if you have that authority and it's safe to do so.
- Transparent Communication: Inform your community immediately via all channels. Hiding a bug destroys trust. Explain what you know, what you're doing, and the next steps.
- Develop and Test a Fix: Create a patched contract. Test it exhaustively on devnet, simulating the exact bug scenario. Never deploy an untested fix.
- Execute the Migration Plan: Have a pre-planned migration path. This often involves deploying a new token contract, snapshotting holder balances from the old contract, and airdropping the new tokens. Learn about airdrop best practices. This is where a loyal community from fair launch practices is crucial.
- Learn and Document: Conduct a post-mortem. How did the bug slip through? Update your development checklist to prevent it in the future.

Frequently Asked Questions
Costs vary widely based on contract complexity. A basic token contract audit can start from $5,000 and go up to $50,000+ for complex DeFi systems. For many creators using standardized templates on a launchpad like Spawned, a micro-audit or peer review (costing $500-$2,000) focused on their customizations may be sufficient. Always budget for security review—it's cheaper than a post-exploit recovery.
Generally, no. Most basic token contracts are immutable once deployed. This is why pre-launch testing is critical. Some advanced standards, like Solana's Token-2022 program used by Spawned for post-graduation, allow for certain 'updateable' features like transfer fees, but core logic is often fixed. If a critical bug is found, the only safe recourse is to migrate all holders to a new, fixed contract via a snapshot and airdrop.
Misconfigured mint and freeze authorities are extremely common. Creators often deploy tokens where the mint authority (ability to create new tokens) is not properly revoked or is held by an insecure account. This allows anyone—or a specific compromised wallet—to mint an infinite supply, destroying the token's value. Using a launchpad template automates the secure configuration of these authorities.
While deep coding knowledge helps, you don't need to be an expert. The best strategy is to use a trusted, pre-audited contract template from a platform like Spawned. Your job is to understand the parameters (like setting your 0.30% fees) and to pay for a professional review of any custom logic you add. The AI website builder also creates a front-end that interacts with your contract correctly, reducing interface-related errors.
Spawned reduces bug risk in three key ways: 1) It provides standardized, tested contract templates for common token types (e.g., gaming tokens), eliminating errors from manual coding. 2) The platform handles secure configuration of critical authorities automatically. 3) The integrated approach ensures your website (AI-built) and contract work together seamlessly, preventing front-end integration bugs. This structured process is far less error-prone than manually copying code from different sources.
Not necessarily—they are just different. Ethereum's bugs are often related to storage costs and complex Solidity quirks. Solana's bugs frequently involve parallel execution, account validation, and compute limits. The ecosystem is younger, so there are fewer battle-tested libraries and more 'copy-paste' code of uncertain quality. This makes using reputable, standardized sources for your contract code even more important on Solana.
Beyond standard token tests, focus on your specific use case. If your [gaming token on Solana](/use-cases/token/how-to-create-gaming-token-on-solana) has in-game reward functions, test: reward claiming under high load, prevention of duplicate claims, and secure integration with your game's backend. Simulate a flood of players claiming at once to check for compute unit failures. Test any admin functions (e.g., to pause rewards) thoroughly.
