How Smart Contract Scans Work
This page explains the smart-contract review flow in customer language.
If you do not care about implementation details and only want to know what Dralvia is doing on your behalf, the short answer is:
Dralvia reads the contract, separates what is visible from what is risky, and turns that into a recommendation your team can use before approving or interacting.
The high-level flow
Every Smart contract review follows the same broad sequence.
1. Dralvia accepts the request
When you submit a contract address, Dralvia first checks basic validity:
- is the address present?
- is the chain supported?
- is there already a recent result that can be reused safely?
If a recent final result already exists, Dralvia can return that result quickly. If not, it starts a fresh review.
In the product, that may appear as a queued or in-progress contract review before the final result is ready.
2. Dralvia reads what can be seen directly
The next step is visibility.
Dralvia checks whether the contract is:
- verified or unverified
- a standalone contract or a proxy shell
- backed by visible implementation logic or opaque bytecode
- exposing readable ABI names or only low-level selectors and bytecode patterns
This matters because good security decisions depend on distinguishing:
- confirmed risk
- uncertain visibility
- normal-but-opaque contracts
Those are not the same thing, and Dralvia treats them separately.
3. Dralvia reviews control surfaces
After visibility, Dralvia looks for the controls that affect real users and real funds.
Examples include:
- owner and admin rights
- proxy admin or upgrade controller paths
- pause or emergency controls
- mint and burn powers
- blacklist, whitelist, cooldown, and transfer-delay controls
- fee and tax-setting paths
- sweep or rescue logic
If a proxy is detected, Dralvia does not stop at the front address. It reviews the proxy shell, the implementation, and the admin surface together so the workspace is not misled by a calm-looking wrapper over more powerful logic.
4. Dralvia reviews token behavior
If the contract behaves like a token, Dralvia goes deeper into trading behavior.
That includes:
- whether trading appears open or restricted
- whether selling appears safe, blocked, punitive, or unclear
- whether approvals and transfers can succeed while exit paths remain dangerous
- whether liquidity appears absent, unlocked, locked, burned, or concentrated
- whether top holder concentration or privileged clustering is abnormally strong
This is where Dralvia helps with cases that simple "honeypot" labels often miss.
5. Dralvia adds historical and relational context
A contract is not judged only in isolation.
Where possible, Dralvia also adds:
- recent upgrade or admin churn
- creator, deployer, or first-funder context
- repeated family similarity
- related suspicious contracts
- policy matches and review-queue escalation for uncertain opaque cases
That context helps explain whether a risky-looking contract is a one-off oddity or part of a larger suspicious pattern.
6. Dralvia composes the result instead of flattening everything into one guess
Older smart contract tools often make one of two mistakes:
- they flatten everything into one big score with no nuance
- or they dump raw facts on the user and make the workspace interpret them alone
Dralvia now uses a clearer decision model.
The main dimensions are:
contract_posture: how risky the contract itself looksaction_risk: how risky the user action appearsconfidence: how strong the evidence istransparency: how much of the contract was directly visiblefinal_decision: what Dralvia recommends next
That means a workspace can tell the difference between:
- a highly risky contract with strong evidence
- a low-visibility contract that needs review
- a contract that looks ordinary enough for routine use
7. Dralvia explains the result in human language
The output is not supposed to be only for engineers.
A good smart contract result should answer:
- What did Dralvia find?
- Why does that matter?
- How sure is Dralvia?
- What should the workspace do next?
That is why Dralvia includes:
- a readable summary
- structured evidence
- decision guidance
- exportable evidence for ticketing and audit
What about wallet approvals and signing?
Contract scanning and wallet-risk review are related, but they are not the same step.
- Contract Scanner helps you understand the contract you are dealing with.
- Pre-Sign Preview & Wallet Risk Review helps you understand the action you are about to sign.
In practice, many teams use both:
- review the contract posture
- review the actual approval or action before signing
What Dralvia does not do during a scan
Dralvia does not:
- approve the transaction for you
- connect a wallet and sign on your behalf
- exploit the contract
- interact with the contract as an active attacker
The goal is review and explanation, not automated execution.
Why some results take longer than others
smart contract reviews vary widely in complexity.
A simple verified contract with a clear ABI is faster to review than:
- an opaque proxy
- a contract with bytecode-only selector recovery
- a token with layered trade controls
- a contract that needs historical or lineage context
That is why Dralvia may briefly show an in-progress review state before the final result appears.
What workspaces should do with the result
Use the result as a decision aid, not just a badge.
- If the final decision is calm and the transparency is high, routine review may be enough.
- If the action risk is high, the workspace should treat the case as an approval decision, not a curiosity.
- If transparency is low and control surfaces remain active, the safest next step is manual review before funds or permissions move.
