frequently asked questions
How much does an audit with Solidified cost?
The cost is determined by the complexity of smart contracts, size of the attack surface and how many experts you’d like to verify the code. For a standard tokensale based on OpenZeppelin contracts, the price is 8-10 ETH per auditor. For custom platforms and services, the expert cost is in the range of 15-20 ETH. Solidified takes a 10% fee for the service.
The verification of fixes is included in the quote.
Running a bounty program with us is a final step, which is highly recommended, in which case additional bug payouts may occur.
What is the audit process like?
Securing your smart contract is a multi-step process. Solidified is the only platform where the entire technical due diligence lifecycle is performed. What does this mean:
Several highly-competent Solidity auditors perform an isolated and unbiased review of your contract. Each of them sits down 1:1 with the contract and prepares an audit report. After each auditor finishes their individual report, they enter into a group debrief. During the debrief, they discuss the validity of each found issue and cross-check each other for quality. From the group consensus, the final combined report is prepared and delivered to the client. The report contains issues in different categories and recommendations on how to fix each issue. You can view our past reports here.
Client addresses the issues found and submits the updated version of the contracts. Solidified uses the same auditors as assigned in Phase 1 to verify that the issues have been fixed and no new vulnerabilities have been introduced. After the verification is complete, the audit report is amended, stating which issues have been addressed, and final version is sent to the client. (We will soon be offering an additional service, where the auditors can implement the fixes for the issues found on behalf of the client.)
The client posts their contract on Solidified bounty platform where it is put in front of the entire verified expert community (150+). This is an optional, but highly recommended step, especially for more complex smart contracts. Client selects incentives for Critical, Major and Minor bugs found and funds the escrow account with the total bounty pool. After this, the contract goes live on bounty and recommended to stay there for at least 2 weeks. If a bug is found and approved (either by client or through community arbitration) the reward is automatically released from the escrow to the bounty hunter.
To further show confidence and transparency in the security of your code, a prediction market is automatically opened for your smart contract on whether a bug will be found in the deployed code within timeframe X. This feature is currently in development.
How long does the audit take?
Tokensales: 4-5 days for initial audit, 1-2 days for verification of fixes.
Custom platforms: 1-2 weeks minimum.
Additionally, add 2 weeks for the bounty program.
How does a Solidified audit compare with other auditing firms?
Most auditing firms perform only a part of the entire audit process (i.e. initial
audit report but no bug bounty), we provide the full process.
Most auditing firms issue a single code expert to secure a smart contract, we provide the largest community of smart contract experts.
Most auditing firms will do a private audit (we publish our audit reports publicly here).
No audit firm is providing a continuous security metric indicating the security of your smart contract and an early waring system if vulnerabilities are found.
Automated tools and formal verification efforts (Quantstamp, Fujitsu, et al.) are much-needed efforts, but cannot be relied upon for a full security audit of complex smart contracts. We use these tools for initial checks to catch 'low-hanging' bugs.
Does Solidified provide a security guarantee after the audit?
Being native to the Ethereum community, we are proud to be working with Nexus Mutual on a smart contract based alternative to insurance.

How many experts are in Solidified network?
There are currently over 200 experts in our network. Our network is comprised of independent Auditors, Bounty Hunters, Expert-level Solidity devs and security researchers.
What are your experts’ qualifications?
Our experts come from one of 4 backgrounds:
- Solidity Auditors (must have track record of past audits)
- Solidity Bounty hunters (must show bounties won)
- Expert-level Solidity devs (must be a contributor to at least 2 major Ethereum projects or a winner of an Ethereum hackathon/coding contest).
- Security researchers (blockchain academics and whitepaper authors, economics and game-theory researchers in cryptocurrency space)
Are the experts employees of Solidified?
No, they are not.
What is the process of becoming an auditor with Solidified?
Every expert must submit application on our site. We verify relevant track record, which must include either past audits, bounties won or prominent contributions to Ethereum projects.
We then review past and current work history to make sure there is no conflict of interest. Finally, we take the recruit through a test audit with an experienced member of Solidified network and evaluate the skill level. We make the final decision as a result.
I want a Solidified t-shirt, what can I do?
Solidified tee is an exclusive swag. You can get it either by becoming a Solidified auditor and performing your first audit, or filing an approved bug during the bounty.
I love the project, how can I contribute?
We were born from the community and consider our members to be of most importance. If you’d like to help, we are currently needing help from Solidity developers, economists, game theory specialists, bloggers and Ethereum community organizers. Email us here

No matter the outcome of our token sale we will pursue our decentralized model to secure smart contracts.
What is the hard cap?
What is the max token supply?
What is the name of the token?
What are the token features?
Rather than serving as a speculative asset, the SOLID token will serve as a means of the collateralized reputation for auditors and bug hunters, as well as a medium of payment for the services they render.
Generally, these actors would stake SOLID tokens when making security assurances, lose the tokens when such assurances are incorrect, and gain tokens when they help secure contracts through audits and bug reports.

Is there a vesting schedule for the team?
Team members have a 1 year cliff with a 3 year vesting period.
What do you need the funds for?
The funds will be primarily used to accelerate development of the Bug Prediction Market features and its economy. Check out the Proceeds Allocation section on our website.
How do you plan to transition from the existing audit model to the new?
Our existing audit model will continue operating until the new system is tested and deployed. We project to switch to the decentralized model by early 2019.
What problems does Solidified aim to solve with Bug Prediction Market?
Solidified aims to significantly improve smart contract security by introducing a fully decentralized bug prediction market. The new model diminishes the current problems of smart contract audits:
- 1. Auditors aren't incentivized to do work thoroughly and righteously.
- 2. Missing transparency and standards make it hard for authors to find reputable auditors.
- 3. Smart contract bugs lead to hacks and malfunctions that hurt the entire Blockchain ecosystem.
Why not use Augur/Gnosis?
We are partnering with Gnosis to collaborate on the infrastructure of the Bug Prediction Market. Augur's prediction oracle is not compatible with our use case.
