Smart Contract Audit to Mainnet: Remediation, Re-Audit and TGE Timing

Security pressure on token projects continues to increase. According to Hacken (the incident count is also reported by PANews), crypto hacks caused $1.18 billion in losses across 107 incidents in the third quarter of 2026. Coverage of the same Hacken data calls it the most damaging three-month stretch since early 2025. In the previous year, access control exploits resulted in approximately $2.12 billion in losses, or 53% of the total losses for all of 2025.

Figures like these encourage any serious team to conduct a pre-launch audit. This is the right approach. However, the error often lies in the timeline. Teams frequently allocate time for the audit itself but fail to set aside time to address the findings detailed in the audit report.

This article examines the token launch process in light of these challenges. It covers the contents of an audit report, the cycle of remediation and re-auditing, and explains why the Token Generation Event (TGE) date becomes fixed at the moment of deployment.

Full Token Launch and Development Timeline

A token launch is a multi-stage project, and the smart contract is only one track inside it. A full token launch plan covers product, legal, economics, marketing and technology. In TokenMinds' project experience, it often runs six to nine months, though scope and legal review can stretch or shorten that. A typical sequence looks like this:

1. Goal setting and product MVP, so investors can see something working
2. Legal structure and compliance review
3. Tokenomics design and whitepaper
4. Website, branding and community building
5. Smart contract development
6. Smart contract audit
7. Remediation and re-audit
8. Contract deployment
9. Token sale rounds, run from private investors through the public sale, then TGE and exchange listings

Marketing and community work run alongside these stages, not after them. TokenMinds adds one check on the technical side as well. Before launchpad or IEO execution, we run an internal smart contract audit and an exchange-readiness review. It flags technical, operational and exchange-onboarding issues early, so they do not first show up in the external report. By the time the audit starts, most of the project is already public. Investors are committed, the community is waiting, and the sale plan points at a date.

In our experience, stage 7 is the one many plans skip. In our experience, teams often book two to four weeks for the audit, but set no time for the fixes and the re-audit that follow. Deployment cannot happen until the re-audit is clean, and the TGE cannot happen before deployment.

The rest of this article walks through that gap. It starts with what the audit report actually contains.

What Does a Smart Contract Audit Report Actually Contain?

A smart contract is the most critical piece of a token launch, and no project can launch without one. It is a program that runs on the blockchain, and it contains the rules of the token. These rules cover the total supply, who receives tokens, when they unlock, and who is allowed to change what.

Because the contract controls the token and the funds, it must pass a security check before launch. That check is the smart contract audit. An independent security team reads the code line by line, simulates attacks, and tests how the contract behaves under unexpected inputs. The purpose is to find the problems before real money sits on the contract. TokenMinds adds its own internal smart contract audit and exchange-readiness review before launchpad or IEO execution. It looks for technical, operational and exchange-onboarding issues early, so fewer of them reach the independent report.

The result of this work is the audit report. A full report usually contains the scope (which contracts were reviewed), the methodology (how they were tested), a findings list, and the trust assumptions (which privileged roles exist and what each one can do). The findings list is the heart of the report.

The report is not a pass or fail certificate. Each finding carries a severity level, which shows how dangerous it is, and a status, which shows whether it has been fixed. Audit firms such as Hacken publish similar severity definitions, scored on how likely the issue is to happen and how much damage it could cause. The scale below comes from a real pre-mainnet audit report.

That real report belongs to a recent token launch project, which stays anonymous here. Its initial audit returned 21 findings in total. Four were medium, 10 were low and 7 were informational. There were no critical or high findings, which sounds like good news.

It was still not a green light to launch. Under the scale above, every one of the 4 medium findings had to be fixed before the contracts could go to mainnet. So the day the report arrived was not the end of the preparation. It was the start of the fixing work.

Inside the Gap: The Audit, Fix and Re-Audit Loop

The first section marked remediation and re-audit as stage 7, the gap that most plans skip. This section explains what fills it.

A token can launch after the remediation loop closes, not after the report lands. The loop has three steps. The auditors deliver the report, the development team fixes the findings, and the auditors verify the fixes in a re-audit.

The loop rarely closes in one pass. In the anonymized project, the first re-audit confirmed 3 of the 4 medium findings as fixed. The fourth needed a second round. The re-audits also surfaced 6 new findings along the way, so the total grew from 21 to 27. Fixing code is new work, and new work can create new findings.

The full loop in this case was one audit, two rounds of fixes, and two re-audits. Only then were the contracts clear for mainnet, and everything else in the launch waited on that moment.

The practical rule is simple. A launch plan should hold time for at least two remediation rounds between the report and mainnet. If the loop closes early, the team gains buffer. If it does not, the date survives.

Why One Finding Can Take Two Rounds to Fix

As the previous section showed, this project still had one medium finding open after the first re-audit. That finding deserves a closer look, because it explains why the loop took a second round. It was an access control issue, and this type is the hardest to close.

The setup was simple. The contracts used roles to control who can do what. One narrow role could block addresses, and a bigger admin role managed the other roles. Closing the finding then took four steps across two rounds:

• First fix. The blocking role was moved away from the main admin, to a separate owner.
• First re-audit. The auditors replayed the attack and found a gap. The main admin could still grant the blocking role back to itself through its wider rights.
• Second fix. The main admin’s power over the blocking role was removed.
• Second re-audit. The fix was confirmed, and the finding was finally closed.

The gap in the first fix follows a pattern called indirect privilege escalation. The direct path is closed, but a longer path through another role stays open. The pattern is common because of how role systems work. In OpenZeppelin’s AccessControl design, every role has an admin role that can grant and revoke it, and the documentation itself flags the default admin role as a significant risk.

The patience paid off for a reason. Access control failures caused 53% of all crypto losses in 2025, according to Hacken, so an auditor that holds a launch on a role finding is protecting the project, not slowing it. Role design is only half the fix. Who holds the powerful roles matters too. A multisig contract needs several valid signatures before it can act, so one stolen or lost key cannot move funds alone. Ethereum's developer docs name 3-of-5 and 4-of-7 as common setups. In a 4-of-7 setup, funds stay retrievable even if three signatures are lost. Ask the auditors whether the admin roles sit behind a multisig.

This is what the gap between the report and mainnet looks like in practice. One finding, two fixes, two checks, and the launch date waiting at the end. The next question is why that waiting date is so unforgiving.

Lock the TGE Date After the Re-Audit, Not Before

The previous section ended with the launch date waiting on the final re-audit. The project could still move that date for one reason. The contracts were not deployed yet.

Deployment is the moment the date stops being flexible. Ethereum’s developer documentation states that smart contracts cannot be deleted by default, and interactions with them are irreversible. On standard non-upgradeable launch contracts, the vesting schedules, unlock cliffs and the TGE timestamp all sit in the deployed code. The same held when TokenMinds worked for Halla Gaming, a client whose token sale platform we built end to end. On BNB Smart Chain, TokenMinds delivered the sale contract with pricing and timing controls, plus vesting for team, advisors, private and public allocations. Each of those schedules had to be confirmed before mainnet. No one can edit them afterwards, including the team that wrote them. This is why TokenMinds keeps sale, vesting and staking logic in audited contracts, not in the backend. There is no server-side setting to quietly fix a wrong unlock date later. What the audit signed off is what runs, so the schedule and date in that code are the ones to confirm before deployment.

So the answer to a common founder question is short. Can the TGE date change after the contracts are deployed? No. The date can only move while the contracts are still off-chain. After deployment, the only route is a fresh deployment at a new address. Deploying is a transaction that costs gas, and Ethereum's developer docs note that deployment gas costs are far higher than a simple transfer. The old contract is not deleted by default, so it stays on-chain. The new code also counts as changed code, so it needs its own re-audit before the new date is safe.

That is why the order of decisions matters more than the decisions themselves. The safe order is a clean re-audit first, then a team-agreed TGE date, then deployment. Many teams run it in reverse. They announce a date, squeeze the audit against it, and hope the report comes back clean. The comparison below shows where each order leads.

The team agreement step deserves emphasis. The TGE date touches engineering, legal, marketing and exchange timelines at once. One function locking it alone creates the exact mismatch that forces a public slip later. TokenMinds holds that keeping product, contracts and compliance under one partner reduces this coordination risk. The token design then stays consistent with what the platform actually delivers, so fewer surprises reach the date discussion.

Capital raising through a token makes this discipline harder, not easier. Investors and the community expect a date early. The honest answer is a window that firms up after the re-audit, not a fixed date that quietly depends on a clean first report.

Readiness work before the audit shortens the whole path. One token sale readiness case shows how early structural checks reduce surprises later. Fewer surprises in the report mean fewer remediation rounds before mainnet.

Pre-Deployment Checklist

One habit protects the whole launch. Go through this list before deployment. Before deployment, everything on it can still be fixed. After deployment, nothing can.

• Make sure the whole team has agreed on the TGE date.
  Not only one person or one department, because the date affects everyone’s work.
• Make sure every medium and higher finding is fixed, and the re-audit confirms it.
  A fix only counts after the auditors have checked it.
• Check the admin roles one more time.
  No role should be able to get its power back through another role. Build a simple map before the final re-audit. List every role and the admin role that can grant or revoke it. Then follow each chain to the end. If any chain loops back to a role that should be locked out, the fix is not done. Ask the auditors to replay every chain on that map in the last re-audit, since a new fix can open a new path.
• Keep room in the timeline for one more fixing round.
  Re-audits can find new problems, and the extra room keeps the date safe.
• Compare the numbers in the contracts with what was announced.
  Supply, vesting and unlocks cannot be corrected after deployment.
• Use the agreed date only in public posts.
  A date that can still move should stay inside the team.

A longer version of this list sits in the token sale readiness checklist. For the gap between audit and mainnet, these six checks matter most. One more comes from a TokenMinds project, the TenCap Launch App, a platform for token launches. On that build, the backend never holds user funds. Every contribution, stake and reward claim is signed from the user's own wallet and confirmed on-chain, and the backend only reconciles from contract events. Anything outside the audited contracts is outside what the re-audit confirms, so keep the money path inside them.

If one check fails, wait. Do not deploy.

What Happens Between the Report and Mainnet

The answer to the title is now complete, and it fits in one paragraph. Between the report and mainnet sits the remediation loop. The auditors list the findings, the development team fixes them, and the auditors verify the fixes in a re-audit. The loop usually takes more than one round, because fixes can be incomplete and new findings can appear along the way.

In the anonymized project, that gap held one audit, two rounds of fixes, and two re-audits. Only then were the contracts clear for deployment, and only then was the TGE date safe to lock.

So the audit report is not the finish line. It is the halfway mark. Teams that plan the gap keep their launch date. Teams that skip it discover the gap anyway, with the whole market watching.

Get a Pre-Launch Review With TokenMinds

The sections above show why the gap needs a plan. Findings block deployment, the fixing loop takes more than one round, and the TGE date becomes permanent the moment the contracts deploy.

TokenMinds has run token sales through every market cycle since 2017. The work covers token sale strategy, tokenomics, smart contract development and go-to-market. That position, between the audit firm and the deployment decision, is where its pre-launch review helps. The review reads the audit report the way an operator does. It shows which findings block mainnet, how many fixing rounds to budget, and when the TGE date is safe to lock. Teams walk in with a report and walk out with a clear deployment order and a date that holds.

FAQs

How long after a smart contract audit can a token launch?
A token can launch only after the remediation loop closes, not when the report lands. In the anonymized project, that meant one audit, two rounds of fixes and two re-audits before mainnet. Plans should hold time for at least two rounds on top of the audit itself, which teams often book at two to four weeks.

What happens if an audit report has medium severity findings?
Medium findings represent real security risks, so auditors and serious teams treat them as launch-blocking. Each one is fixed and then verified in a re-audit. In one recent case, 4 medium findings all required fixes before mainnet, and one needed a second round.

Can the TGE date change after the token contracts are deployed?
No. Deployed contracts are permanent on standard non-upgradeable launch setups, and the TGE date sits in that code. On a proxy setup, the upgrade admin can change that logic, so confirm who holds that role and whether a timelock delays it. The date should be agreed by the whole team after a clean re-audit and before deployment.

Do low and informational findings have to be fixed before mainnet?
Not always. Under the severity scale above, low findings are fixed when possible or documented and accepted. Informational notes go into a future cleanup. Medium findings and above must be fixed and confirmed. Write down every accepted low finding, so the team knows what it ships with.

What does a re-audit check?
The auditors verify each fix and replay the original attack path. In the anonymized project, the first re-audit found a gap in the access control fix. Re-audits can also surface new findings. Here, 6 new ones took the total from 21 to 27.
