Request an audit
Chains
Choose Solana audit companies by the program they reviewed, the evidence they deliver and the changes they agree to recheck. These ten providers offer different starting points for application audits, token infrastructure and continuing security work. Our archive census found 14 Token2022-family files, including a commit attestation that explicitly is not a full audit report.
Choosing a security firm
The top 10 cybersecurity companies below are ranked for one buyer: a team shipping a product that has smart contracts on one side and a web application, an API and a cloud account on the other. Each entry was checked on September 3, 2026 against the firm's own published material, and the three archives that sit on GitHub were counted through the API rather than estimated. One of the ten publishes price bands and lead times before the sales call, and the other nine quote on request.
Services
Pharos Production publishes security services for contract code, applications and the infrastructure around them. Effective Web3 cybersecurity procurement connects those scopes to the assets being reviewed, the evidence delivered and the people who own remediation. Our complete service-page census identifies the dedicated destinations and the boundaries a buyer should confirm.

Audit alternatives
A crypto bug bounty program needs clear scope, authorized testing conditions and an operational path from a valid report to remediation and payment. A maximum reward and a displayed vault balance describe different things; neither replaces the program terms.
Operations
A credible DeFi hack post mortem connects a verified timeline, the violated security property and evidence that the repair was checked. Recovery amounts and audit coverage need separate records; an incident archive cannot fill gaps in either.
Personas and market
Security duties depend on the entity and activity being regulated. MiCA security obligations connect to DORA and operational controls, so a smart contract audit can support technical evidence without establishing authorization or full compliance.
Tooling
Useful protocol invariants connect a security property to the state transitions and assumptions under which it must hold. An AMM pricing check, lending solvency rule and vault preview relationship need different models; code coverage alone cannot establish them.
Token risk
A negative honeypot result is a time-bound observation, not proof of future safety. Rug pull scanner limits include unavailable responses, changing authority and liquidity conditions that require separate evidence.
Audit deliverables
Public smart contract audit report examples are useful when they connect a reviewed artifact to findings, limitations and remediation evidence. Our deterministic sample of ten Trail of Bits documents shows why assessments and fix reviews must be read differently.
EVM patterns
A standard library can be reviewed while the application built from it remains unsafe. Smart contract dependency risk comes from the chosen version, local overrides and assumptions about live external systems, so each boundary needs its own evidence.
Tooling
Treat scanner output as a set of claims to investigate. Solidity static analysis triage should preserve the reported impact and confidence, then establish reachable behavior before a finding is fixed, suppressed or sent to an auditor.
Personas and market
Define the security decisions that need a permanent owner before choosing a job title. A Web3 security engineer, an audit manager and a security platform developer can have different responsibilities, so salary evidence must preserve role and location.
Audit alternatives
A researcher needs an authorized reporting route and a reproducible impact claim before expecting a bounty. For white hat hacker Web3 work, a contact address, safe-harbor agreement and reward promise are separate records with separate conditions.
Services
Pharos Production publishes security services for contract code, applications and the infrastructure around them. Effective Web3 cybersecurity procurement connects those scopes to the assets being reviewed, the evidence delivered and the people who own remediation. Our complete service-page census identifies the dedicated destinations and the boundaries a buyer should confirm.
Operations
Production authority should follow a documented operating model with verifiable limits. Admin key management connects custody to the actions each account can reach and proves when an old authority has been removed.
Verticals
A destination bridge must justify why it accepts a message and the asset claim that follows. Cross chain bridge security depends on that verification rule, its administrative overrides and the accounting on both sides.
Operations
Start crypto incident response by assigning authority, preserving the first evidence and checking which containment actions the deployed system can execute. Our census of 84 public SEAL 911 log entries includes 10 takeover labels, making domain and account recovery relevant to the exercise as well as contract controls. Keep notification, containment and confirmed recovery as separate states.
Services
A team badge records a provider's identity checks; it does not guarantee honest behavior or safe code. Crypto team KYC verification is useful only when its scope and current project binding are clear.
Verticals
A vote count is only one stage in the path to a treasury transfer or upgrade. A DAO security audit follows that path through historical voting weight, executable payloads and every alternate privileged route.
Personas and market
A firm name beside a hacked protocol does not establish that the attacked deployment was in its review. Comparing DeFi hacks by auditor requires incident evidence, the original scope and a dated deployment match.
EVM patterns
Before listing, an issuer needs evidence for token behavior and the integrations that rely on it. An ERC20 token audit ties that evidence to a revision, current authority and the remaining compatibility limits.
Attack classes
Temporary financing amplifies a missing constraint in the protocol that accepts a price, claim or vote. A flash loan attack review follows the lasting benefit after repayment and tests the state that authorized it.
Audit alternatives
A proof supports a specified property under stated assumptions, so its scope matters as much as its result. For formal verification smart contracts work, fund the properties that address consequential failures and require reproducible evidence.
Verticals
A lending protocol audit follows borrowing limits, interest accounting and loss recovery through the actual loan model. We compared 28 Comet configuration files to show how a complete parameter inventory supports that scope. XRPL credit needs a different review because its documented lending model relies on off-chain underwriting.
Verticals
A perpetual DEX security audit tests margin accounting, liquidation execution and who absorbs losses when normal settlement fails. Our snapshot resolved the margin rules for 177 Hyperliquid markets, including 34 with multiple tiers. Use that configuration inventory alongside a venue-specific loss model when commissioning the review.
Attack classes
Callbacks become dangerous when another reachable operation can use unfinished accounting. A reentrancy attack review must cover shared state, downstream consumers and the actual protection in the deployed version.
Verticals
A review of RWA token security depends on both implemented token controls and the evidence supporting the holder's asset claim. Our pinned T-REX reference scan found 14 direct role gates among 27 mutating declarations, plus batch paths that need separate interpretation. Use that distinction to scope identity, transfer and custody review.
Audit process
Comparable quotes begin with the same code boundary and requested evidence. A smart contract audit RFP should make scope differences and fix-review terms visible before price determines the decision.
Audit process
A credible launch plan separates provider availability from review, fixes and deployment acceptance. A smart contract audit timeline needs a stable scope and named owners for each dependency, not a generic turnaround promise.
Token risk
Hidden authority becomes visible by tracing who can reach a balance change or replace the rules. Smart contract backdoors require that analysis, while documented privileges need a clear statement of their limits.
Services
A useful model turns an unwanted outcome into a reachable path and a testable property. Smart contract threat modeling also names the assumptions and operating controls that a code-only review cannot establish.
Chains
Commission a Solana smart contract audit around account relationships, delegated privileges and the token behavior your program accepts. Our source-registry scan classified 28 Token-2022 extension types, showing why a program-ID check alone cannot define integration scope. Bring a pinned build and an explicit acceptance policy to the reviewer.
Chains
Choose Solana audit companies by the program they reviewed, the evidence they deliver and the changes they agree to recheck. These ten providers offer different starting points for application audits, token infrastructure and continuing security work. Our archive census found 14 Token2022-family files, including a commit attestation that explicitly is not a full audit report.
EVM patterns
An upgrade changes the rules that interpret existing state. An upgradeable contract audit must bind the starting deployment, candidate implementation and executed payload to a tested migration and authority model.
Chains
Compiler assurance and application assurance answer different questions. A Vyper contract audit must connect the source, compiler settings and deployed behavior while checking language-specific protections and known advisories.
Personas and market
A useful tokenomics audit tests economic assumptions and connects them to the rules a token actually enforces. Request reproducible scenarios and a findings report with explicit limits. Our scan found an explicit service offer on 1 of 16 readable member sites, showing why topic mentions need a closer check.
Personas and market
A crypto due diligence checklist should end in an evidence chain, not a row of green badges. We apply that standard to Lido on Ethereum by tracing two live proxies into verified implementations, matching the deployed scope to an audit commit and mapping privileged functions to their current control path. Our separate survey of 30 top total value locked records shows why the extra work matters: only 16 supplied an audit link, and a link alone says nothing about scope.
Token risk
Every honeypot token detection service answers with a simulated trade, not with a statement about the token. A checker buys and sells against one live pair at one block, then reports what happened to that trade. This guide takes the method apart, names the four contract patterns that survive it, and reports our own run of 150 tokens through two public checkers on September 4, 2026.
Attack classes
An oracle manipulation attack rarely breaks the oracle. It moves the venue the oracle reports, or reads a price the protocol should never have trusted, then borrows against the result. This comparison sizes spot reads, Uniswap TWAPs, Chainlink push feeds and pull oracles by what an attacker has to control, and carries our own survey of every Chainlink feed parameter published on four networks.
Attack classes
A signature replay attack reuses bytes the real owner already signed. It needs no forged signature: a verifier accepts the authorization in an unintended context or lets a one-use request execute again. This guide maps common authorization gaps to auditor checks, then measures what 155 member firm reports actually say.
Audit alternatives
Code4rena, the platform that made the smart contract audit contest famous, is closing its doors, which changes the answer for every team choosing between a contest, a private firm and a bug bounty. This guide prices contests and private review from platform data read on September 4 2026, across 40 finished contests on two platforms, and describes the bounty layer rather than pricing it. It ends with a routing rule that survives the disappearance of any single venue.
Operations
The job called smart contract monitoring starts once the audit is over: watching a live contract's events and storage slots for the changes that matter, then getting a person or a script to act on them. This guide names the events with their exact signatures, gives a procedure for deriving alert thresholds rather than copying someone else's, and walks the escalation path from a firing rule to a pause transaction. It also dates the end of OpenZeppelin Defender and measures how many alliance member firms publish a monitoring service at all.
Audit deliverables
An audit report explained properly starts at the scope statement and the dates, not at the findings table. Everything below those pages is conditional on them: which files were read, in what window and under which severity rule the firm writes its labels. This guide walks a real published report end to end, and measures the severity and status vocabulary that member firm reports actually use.
Audit deliverables
A fake audit report is a document that claims a security review which never happened, or a real report that no longer describes the code you are about to use. Both are caught the same way, by checking the report against the two things it should name: the commit that was audited and the deployed address it maps to. This guide gives the procedure, and a measurement of how often published reports carry those anchors at all.
Choosing a security firm
The top 10 cybersecurity companies below are ranked for one buyer: a team shipping a product that has smart contracts on one side and a web application, an API and a cloud account on the other. Each entry was checked on September 3, 2026 against the firm's own published material, and the three archives that sit on GitHub were counted through the API rather than estimated. One of the ten publishes price bands and lead times before the sales call, and the other nine quote on request.
Disclosure and bounties
A security disclosure policy is the published set of rules that tells a researcher where to send a vulnerability report, what they may test and what happens next. On September 2, 2026, only 3 of the 30 largest DeFi protocols by TVL served a security.txt file, and one of those three met RFC 9116. This guide gives protocol teams the policy wording, the file, the SEAL Safe Harbor steps and the response deadlines, each tied to a published source or to the terms real adopters set.
Tooling
Fuzzing generates inputs and call sequences against compiled contracts and checks that stated properties hold. Echidna, Medusa and Foundry all do smart contract fuzzing, with different default budgets, coverage guidance, shrinking and setup cost, so the right pick depends on whether the bug you fear needs one input or a sequence of calls. This guide gives the decision path, a settings matrix from each tool's current documentation, and a scan of what the 30 largest DeFi protocols actually keep in their repositories.
