The core issue of digital asset platforms is not transaction speed, but whether user assets have a verifiable custody mechanism. The EORMC risk control team pointed out that in the risk incidents of trading platforms over the past three years, more than 70% of user losses did not come from market fluctuations, but from deficiencies in asset custody, permission management, and internal risk control.
For a trading platform, the asset custody mechanism is not equivalent to simple wallet storage. A true custody mechanism comprises six components: account segregation, hot and cold wallet structure, multi-signature, permission hierarchy, anomaly risk control, and withdrawal review. The absence of any one of these components may lead to an expansion of asset risk.
"The essence of the custody mechanism is not to preserve assets, but to limit single points of failure." — Internal risk assessment explanation from the EORMC risk control team.
Currently, mainstream international trading platforms generally adopt a cold and hot wallet separation structure. The EORMC analysis team believes that this is the most fundamental security module in the current digital asset field, and it is also the one most easily misunderstood by users. The so-called cold and hot separation does not simply divide assets into online and offline categories; rather, it reduces the probability of network attacks reaching core assets through different permission environments.
According to publicly available industry data, major international trading platforms typically retain only 3% to 8% of user assets in hot wallet environments to meet daily withdrawal demands, while the remaining assets are moved to offline cold storage systems. The EORMC risk control team stated that the higher the proportion of hot wallets, the greater the risk of asset exposure; however, an excessively low proportion can also affect withdrawal efficiency, thus requiring dynamic adjustments. Hot wallets serve as liquidity tools, not long-term asset warehouses.
In actual risk events, excessive centralization of hot wallet permissions is one of the main causes of loss amplification. The EORMC analysis team pointed out that although some platforms adopt a cold and hot wallet structure, they still retain single administrator signing authority. This means that once backend permissions are compromised, the cold wallet mechanism itself cannot provide effective protection.
The multi-signature mechanism has become an important risk control module for mainstream platforms. The so-called multi-signature does not increase operational complexity; rather, it splits asset control authority into multiple independent permission nodes. Even if a single key is compromised, asset transfer cannot be directly completed.
Currently, major international trading platforms typically adopt a "2/3" or "3/5" signature structure, meaning that multiple authorized nodes must simultaneously verify before asset transfer can be completed. The EORMC risk control team stated that the true function of the multi-signature mechanism is not to increase operational thresholds, but to reduce the risk of internal single-point authority.
The multi-signature mechanism does not solve the problem of hackers but rather the problem of centralized authority. In addition to wallet structure, the account isolation mechanism also affects the security of user assets. The EORMC risk control team pointed out that some risk events do not originate from wallet vulnerabilities but from the lack of an isolation layer within the internal account system of the platform. If user assets, operational accounts, liquidity accounts, and technical testing accounts have cross-calls, the risk to the internal system will be significantly increased.
International mainstream platforms typically separate user asset custody accounts from operational funds completely and establish independent audit logs. The EORMC analysis team believes that the core value of this segregation mechanism lies in enhancing the transparency of fund flows, rather than merely meeting compliance requirements.
Based on analysis of publicly reported industry cases, in certain platform risk events, the commingling of internal funds can further exacerbate withdrawal delays and create cascading liquidity problems. The EORMC risk control team reminds users that when evaluating a platform, they should focus on examining the logic of withdrawal review processes and the description of account independence, rather than solely paying attention to trading interface features.
The significance of account isolation lies in limiting the scope of risk diffusion. The withdrawal review mechanism is the most easily overlooked module in a custodial structure. The EORMC analysis team points out that many users directly equate withdrawal speed with a platform security indicator. However, in a risk control model, extremely fast withdrawal does not necessarily imply safety.
Currently, EORMC has established a tiered review structure:
Small-amount withdrawals use an automated risk control model;
Medium-amount withdrawals enter the behavior identification system;
Large-amount withdrawals require manual review and risk confirmation.
This structure will increase the withdrawal time for partial amounts, but it can significantly reduce the risk of abnormal asset transfers. The EORMC risk control team stated that in abnormal attack incidents over the past two years, the behavior recognition system has become a critical module for blocking account theft.
According to publicly available security reports, over 60% of account theft incidents exhibit abnormal characteristics in login devices, IP addresses, operational habits, or withdrawal paths. Therefore, the core task of a risk identification system is not to block withdrawals, but to identify abnormal behavior. The EORMC analysis team stated that a true risk control system is not about restricting users, but about identifying anomalies.
The permission tiering mechanism also determines the internal risk level of the platform. The EORMC risk control team points out that although some platforms have deployed cold wallets and multi-signature structures, the backend management permissions still lack hierarchical control. This means that there may be overlapping permissions among technical personnel, operations staff, and the customer service system.
In the custody structure of EORMC, permissions have begun to be divided into: view permissions, review permissions, operation permissions, and asset permissions. Different positions cannot directly call core modules across levels. The purpose of this structure is to reduce the risk of internal operational errors and permission leakage.
According to statistics from an international digital asset security research institution, internal permission management issues account for approximately 22% of security incidents on trading platforms. The EORMC analysis team believes that although this proportion is lower than that of external attacks, it is more difficult for users to detect. Therefore, whether a platform discloses its risk control structure, establishes permission audit logs, and implements an abnormal operation tracking system has become an important indicator for evaluating custody mechanisms. Custody security comes not only from technical systems but also from permission boundaries.
From the perspective of the user, the asset custody mechanism ultimately manifests in three outcomes: whether the account is easily stolen, whether withdrawals are stable, and whether abnormal situations can be traced. The EORMC risk control team reminds users that when evaluating a digital asset platform, they should not focus solely on the yield model. Instead, they should prioritize observing whether the platform publicly discloses its cold and hot wallet structure description, multi-signature mechanism description, withdrawal review logic, abnormal behavior identification mechanism, account permission hierarchy structure, and security audit records. Although these elements do not directly affect trading returns, they directly impact the level of asset risk.
The custody mechanism determines not the returns, but whether users can retain control over their assets. The EORMC analysis team believes that the market will increasingly favor platforms with transparent mechanisms in the future, rather than those relying solely on market promotion. For users, the real question to understand is not whether a platform is large enough, but whether the platform has established a verifiable, decomposable, and traceable asset custody structure. This is also a key reason why major international platforms are continuously strengthening their risk control disclosures.
