Why is BlockATM so vulnerable to hackers? Decoding its core security logic

In the cryptocurrency world, asset security is always a core concern. The key to BlockATM, a cryptocurrency payment gateway, effectively combating the risk of hackers stealing coins lies in its decentralized security architecture built on blockchain technology. Every design detail is focused on preventing theft, ensuring complete peace of mind for merchants using it.

1. User-Deployed Contracts: Cutting Off Hacker Access at the Source

BlockATM's coin collection contracts are user-deployed, with direct access to the complete contract code and related information before deployment. This means contract creation is completely under user control, without the need for any third-party platform or institution, eliminating the risk of contract tampering due to compromised platform servers.

2. Self-Custody of Assets in a Dedicated Contract: No Centralized Vulnerabilities

Unlike the centralized custody model of traditional payment platforms, cryptocurrency paid at BlockATMs goes directly into a user-deployed, dedicated coin collection contract, which is managed autonomously throughout the entire process, with no centralized institution involved in the flow of funds. This "non-custodial" model eliminates the most common attack paths for hackers: Traditional platforms' centralized fund pools are prime targets for hackers. Once hackers compromise the server, they can steal funds en masse. However, BlockATMs lack a centralized fund pool. Each user's assets are dispersed across independent contracts, requiring hackers to compromise numerous contracts individually, a cost far exceeding the benefits. Furthermore, contract addresses are generated by the blockchain algorithm and are strongly tied to the user's wallet, making it impossible for hackers to "claim" other people's contract assets through identity theft or phishing schemes.

Third, Strict Division of Permissions: Double Locking of "Withdrawal" and "Receiving"

BlockATM's coin receiving contract implements a strict division of asset permissions: only the [Authorized Signature Address] written into the contract has "asset withdrawal" permissions; withdrawn assets can only be transferred to the pre-set [Asset Receiving Address] and cannot be transferred to other addresses. This "double lock" mechanism makes it difficult for hackers to complete a theft loop, even if they somehow gain partial access. If a hacker only obtains the "authorized signature address," the theft will be immediately detected by the user, as the assets must be transferred to a fixed "receiving address" (usually the user's primary wallet). Any attempt to tamper with the "receiving address" would require violating the contract's immutability—a nearly impossible feat on the blockchain.

Fourth, Smart Contract Immutability: Once the rules are established, there is no "backroom manipulation."

The BlockATM's coin collection contract is essentially a smart contract deployed on the blockchain. Its core characteristic is "once deployed, it is permanently immutable."

This means that hackers cannot modify the contract's permission rules (for example, by adding a new "authorized address") by attacking the platform's backend. The contract's operating logic is executed exactly as originally written, leaving no room for human intervention, thus eliminating the risk of theft caused by malicious manipulation by platform insiders.

Summary: Decentralized Architecture Builds a "Zero Trust" Security Barrier

BlockATM's security logic can be summarized as "User Controls Everything, Code Replaces Trust": From contract creation to asset custody, from permission allocation to rule enforcement, the entire process requires no third-party reliance, and all operations are publicly traceable and tamper-proof on the blockchain.

For hackers, stealing coins requires simultaneously breaching four layers of defense: "user-independent contract review," "decentralized fund pool," "double-locked permissions," and "tamper-proof contracts." This level of difficulty is comparable to attempting to "remove objects remotely" in an open and transparent environment. This is the core strength of BlockATM's ability to resist theft, and the reason so many merchants trust and use BlockATM.
