EVM compatibility lowers attacker setup cost because existing draining kits already understand ERC-20 approvals, permit flows, and common router interactions. A new EVM chain can often be added by changing chain ID and RPC details, while non-EVM support usually needs bespoke engineering. That makes EVM launches faster to operationalise for criminals.
Why EVM Chains Are Easier for Drainer Operators
EVM compatibility does not make a chain more secure or less secure by itself, but it does make the attacker workflow more portable. Drainer operators can reuse the same wallet-draining logic across many chains because the transaction model, token standards, and common approval patterns stay familiar. The result is a lower engineering cost per target chain and faster expansion when a new EVM network gains user attention.
That portability matters because many drainer kits are built around predictable wallet interactions, not chain-specific novelty. When the same approvals, permits, and router patterns appear across multiple networks, the operator mainly needs to adjust network parameters rather than rebuild the fraud flow. Non-EVM chains often break that reuse advantage, so the attacker has to invest more time in custom support before the campaign is worth scaling.
What Changes When a Chain Is Not EVM-Compatible
Non-EVM ecosystems tend to raise the operator’s setup burden in several practical ways. Different transaction formats, signing paths, token representations, and application tooling can force bespoke development and testing. That increases friction for commodity attackers, especially those buying or renting prebuilt kits that were optimized for the EVM stack.
The economic effect is simple: if a drainer kit can be redeployed with minor configuration changes, criminals can respond quickly to new launches, airdrops, and hype cycles. If the chain requires custom engineering, the attacker must spend more effort for less immediate coverage. That usually shifts their attention toward ecosystems where their tooling already works and where victims are abundant enough to justify the reuse.
Why Exposure, Not Just Technology, Drives Target Selection
Attackers are not only selecting the easiest protocol surface, they are selecting the easiest path to monetisation. EVM chains usually offer a larger pool of compatible wallets, dapps, routers, and liquidity venues, which means a larger number of familiar interaction patterns to abuse. That makes campaign planning easier and lowers the chance that a support mismatch will break the drain flow mid-operation.
For defenders, the important point is that chain compatibility shapes attacker operational efficiency more than it shapes exploit sophistication. The more a chain resembles the rest of the EVM ecosystem, the more reusable the malicious infrastructure becomes. That is why rapid launches, large user inflows, and identical approval UX can attract drainer attention even when the underlying chain itself is not uniquely vulnerable.
Risk and Threat Considerations
Drainer activity follows operational convenience, so ecosystems that maximise reuse for existing fraud kits tend to inherit a larger share of opportunistic abuse. The risk is not that EVM compatibility is inherently unsafe, but that it compresses attacker setup time and makes scaling across chains easier once one campaign is built.
Failure mechanism: Attackers reuse the same draining logic across EVM-compatible networks by swapping only chain identifiers, RPC endpoints, and target-specific parameters, while non-EVM support often requires custom engineering that slows deployment.
Impact: More EVM-compatible chains become economically attractive targets sooner after launch, which increases the volume of phishing, approval abuse, and wallet-drain attempts against users on those networks.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
MITRE ATT&CK and OWASP API Security Top 10 address the attack and risk surface, while CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| MITRE ATT&CK | T1583 — Acquire Infrastructure | Drainer operators reuse infrastructure and tooling across chains to scale campaigns. |
| Recommendation — Map campaign infrastructure reuse and staging to T1583 and hunt for repeated operator setup patterns. | ||
| OWASP API Security Top 10 | API8 — Security Misconfiguration | EVM chain integration often relies on predictable configuration and routing assumptions. |
| Recommendation — Review exposed wallet and dapp integrations for configuration weaknesses that simplify abuse. | ||
| CIS Controls v8 | CIS-17 — Incident Response Management | Faster drainer deployment increases the need for detection and response readiness. |
| Recommendation — Validate that wallet-drain alerts and response playbooks are ready before new chain adoption. | ||
| NIST CSF 2.0 | DE.CM-01 — Network Monitoring | Monitoring is needed to spot rapid abuse of familiar approval and routing patterns. |
| Recommendation — Monitor wallet interaction telemetry for unusual approval and drain patterns across chains. | ||
Practitioner Guidance
What to verify: Treat chain popularity and EVM compatibility as threat-amplifying conditions, not as root causes. If a new network preserves familiar approval and routing patterns, assume commodity drainer infrastructure will arrive quickly and validate whether your users are being exposed through the same wallet flows already seen elsewhere.
What practitioners underestimate: The attacker advantage is often reuse, not innovation. A chain can become a target simply because it is easy to add to an existing kit, so security teams should monitor user-facing wallet interaction patterns and phishing exposure as the ecosystem grows, rather than waiting for bespoke exploits to appear.
Practitioner takeaway: The practical security question is not whether a chain is EVM-compatible, but whether that compatibility lets existing fraud tooling scale faster than your detection, education, and response can keep up.
