Vitalik: Survival Comes First for Crypto Companies as Security Takes Center Stage Over the Next Two Years

The crypto industry is entering a period in which resilience may matter more than rapid expansion.

In a recent interview, Ethereum co-founder Vitalik Buterin argued that many companies and institutions will treat survival as their primary objective over the next two years. His assessment reflects a broader shift in the blockchain security landscape: while attacks remain a persistent threat, the most vulnerable points are increasingly found outside the core smart contract layer.

This does not mean that decentralized protocols are risk-free. Instead, it suggests that security is becoming a system-wide challenge involving smart contracts, user interfaces, private-key management, centralized services, operational procedures, and regulatory oversight.

Smart contract security is improving, but the attack surface is moving

Smart contracts remain one of the most important security concerns in decentralized finance. A coding error can potentially allow attackers to drain funds, manipulate protocol logic, or exploit weaknesses in governance and market mechanisms.

However, the industry has made meaningful progress in several areas:

• More mature audit practices
• Greater use of formal verification and automated testing
• Improved bug bounty programs
• Wider adoption of battle-tested libraries
• More careful deployment and upgrade procedures
• Increased scrutiny of protocol governance and permissions

Ethereum’s own security guidance emphasizes that users and developers must evaluate risks across the entire application stack rather than relying solely on the reputation of a blockchain network.

According to Vitalik’s assessment, many major incidents over the past year and a half have increasingly involved the user interface or centralized infrastructure surrounding blockchain applications. Phishing websites, compromised front ends, leaked credentials, flawed access controls, insecure cloud environments, and failures at custodial service providers can all create entry points for attackers.

This is an important distinction. A blockchain may execute code exactly as designed while users are still exposed through a malicious website or a compromised service provider.

Security is no longer limited to protocol developers

For years, blockchain security discussions often focused on the quality of smart contract code. That remains essential, but it is only one part of the equation.

A complete security model must also consider:

1. How users access an application
   A secure protocol can still be undermined if its website is altered or if users are directed to sign malicious transactions.

2. How private keys are stored and used
   If a key is exposed through malware, phishing, poor backup practices, or an insecure device, the underlying blockchain cannot reverse the resulting transaction.

3. How centralized components are operated
   Exchanges, custodians, bridges, RPC providers, and institutional infrastructure often manage sensitive permissions or large concentrations of assets.

4. How transactions are reviewed
   Users may approve transactions without fully understanding the contract address, token allowance, spending limit, or destination of funds.

5. How organizations respond to incidents
   Monitoring, withdrawal controls, incident response plans, and transparent communication can determine whether a security event remains contained.

This broader view is consistent with the Financial Stability Board’s recommendations for crypto-asset regulation and supervision, which call for stronger governance, risk management, and accountability across the digital-asset ecosystem.

The industry may be moving from growth-first to resilience-first

The crypto market has traditionally rewarded speed. Companies compete to launch new products, attract liquidity, expand into new jurisdictions, and support emerging technologies.

But rapid growth can also increase operational complexity. A larger user base, a broader product range, and more aggressive trading or lending strategies create additional opportunities for mistakes and attacks. If security investment does not grow at the same pace, efficiency gains may simply lead to greater risk exposure.

This is the central concern highlighted by Vitalik: better tools, artificial intelligence, larger engineering teams, and improved infrastructure can increase productivity, but those gains do not automatically produce a safer industry. Organizations must deliberately use additional capacity to improve testing, monitoring, access control, and recovery procedures.

A survival-first approach could lead companies to:

• Reduce unnecessary product complexity
• Limit privileged access and administrative permissions
• Separate critical operational systems
• Introduce stronger transaction review processes
• Improve treasury and custody controls
• Conduct regular incident-response exercises
• Delay launches that have not passed adequate security testing
• Maintain sufficient reserves and liquidity for unexpected events

In this environment, the ability to withstand a security incident may become as important as the ability to generate short-term growth.

Why institutions are likely to accelerate on-chain infrastructure

Vitalik also pointed to the possibility that large exchanges, custodians, and financial institutions will increasingly deploy operations directly on blockchain infrastructure.

This direction could offer several advantages. Smart contracts can make transaction rules more transparent, reduce reliance on opaque internal databases, and enable assets or processes to be managed through auditable on-chain logic. When designed properly, users may benefit from consistent execution and stronger visibility into how funds move.

However, moving activity on-chain does not remove risk. It changes the type of risk that must be managed.

Institutions still need to evaluate:

• Smart contract permissions
• Upgrade keys and governance mechanisms
• Oracle dependencies
• Cross-chain bridges
• Wallet security
• Key-recovery procedures
• Compliance and transaction monitoring
• Front-end integrity

The objective should not be to place every process on-chain simply because it is technologically possible. Instead, organizations should identify which functions benefit from transparent, verifiable execution and then build the necessary safeguards around them.

Quantum resistance is an example of long-term security planning

Another important part of the security conversation is preparing for threats that may not be urgent today but could become significant in the future.

Ethereum researchers and developers have been exploring quantum resistance as part of the network’s long-term roadmap. The concern is that sufficiently powerful quantum computers could eventually threaten widely used cryptographic systems. While such a scenario is not an immediate operational threat for most users, transitioning cryptographic infrastructure takes time.

Vitalik has highlighted efforts to develop quantum-resistant signatures and wallet technologies. This illustrates an important principle: security preparation often needs to begin before a threat becomes widespread. Waiting until an attack is actively occurring may leave too little time for infrastructure providers, developers, institutions, and users to migrate safely.

The same principle applies to more immediate risks such as phishing, wallet-draining contracts, insider compromise, and centralized-service failures.

Regulation may place greater emphasis on operational responsibility

As the financial impact of crypto-related incidents grows, regulators are likely to focus more closely on how companies prevent and respond to security failures.

That could include expectations around:

• Customer-asset segregation
• Cybersecurity governance
• Internal controls
• Disclosure of major incidents
• Custody standards
• Business continuity
• Risk-based product design
• Accountability for negligent operations

This does not mean that regulation can eliminate technical risk. No framework can prevent every exploit or user mistake. However, clear responsibility standards can encourage companies to treat security as a core business function rather than a secondary engineering concern.

For the industry, this may mark a transition from “move fast and fix problems later” toward a model in which security, compliance, and resilience are considered part of product design from the beginning.

What users should do as the security landscape evolves

Individuals remain an important part of the security model. Even when protocols, exchanges, and wallet providers improve their defenses, users can still lose funds by signing malicious transactions or exposing their recovery phrases.

A practical personal security routine should include:

• Keeping recovery phrases offline and private
• Verifying website domains before connecting a wallet
• Reviewing transaction details before signing
• Limiting token approvals and permissions
• Using separate wallets for different risk levels
• Avoiding unknown links, airdrops, and unsolicited messages
• Updating wallet software through trusted channels
• Testing recovery procedures before storing significant assets
• Treating every transaction as potentially irreversible

A hardware wallet can add another layer of protection by keeping private keys isolated from an internet-connected computer or phone and requiring a deliberate physical confirmation before signing. OneKey hardware wallets are designed for this self-custody workflow, helping users make transaction approval a more visible and controlled process rather than an invisible background action.

No wallet can protect users who approve a malicious transaction or disclose their recovery phrase. The final layer of security remains user awareness and disciplined operational habits.

Security will become a competitive advantage

The next phase of crypto development may not be defined only by faster networks, lower fees, or new financial products. Users and institutions are likely to pay greater attention to whether a platform can protect assets, recover from incidents, communicate clearly, and operate responsibly under pressure.

Vitalik’s warning is therefore broader than a prediction about the next two years. It is a reminder that sustainable adoption requires the industry to convert technical progress into safer user experiences.

The scope of what can be done securely on-chain is expanding. The challenge is ensuring that greater efficiency and stronger infrastructure are used to reduce risk rather than simply enable more aggressive risk-taking.

For crypto companies, survival may become the first measure of success. For users, security awareness may become the most important investment.
