However, before engaging in trading, investment, or using decentralized applications, three core concepts must be understood: hot wallets, public keys, and self-custody wallets.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These concepts determine not only how assets are stored but also the security boundaries and how it is controlled. Many security incidents stem not from technical vulnerabilities but from users\u2019 insufficient understanding of these three elements, leading to operational errors or inadequate risk awareness.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This article systematically examines the underlying logic of hot wallets, public keys, and self-custody wallets across multiple dimensions\u2014technical principles, security mechanisms, risk models, practical applications, and management strategies\u2014to help readers establish a comprehensive digital asset security management framework.<\/span><\/p>\n<h2>Understanding Blockchain Account Structures: Starting with Public Keys<\/h2>\n<p><span style=\"font-weight: 400;\">In traditional financial systems, accounts are maintained by banks, and users access their balances through usernames and passwords. In blockchain systems, there is no conventional \u201caccount system.\u201d Blockchain networks do not recognize identities; they only recognize cryptographic signatures.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is where the public key becomes essential.<\/span><\/p>\n<h3><b>Defining the Public Key<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A public key is a public parameter derived from a private key through a mathematical algorithm. It has the following characteristics:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Can be publicly disseminated<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Used to verify signatures<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Can be used to generate addresses<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Does not confer asset control capability<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A public key is essentially a public identity credential that proves whether a given signature originated from the corresponding private key.<\/span><\/p>\n<h3><b>The Role of Public Keys in Transactions<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">During a blockchain transaction, the transaction data must be signed. The signature is generated by the private key, and the network uses the public key to verify the signature\u2019s validity.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In other words:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The private key is responsible for signing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The public key is responsible for verification<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Thus, public keys can be shared openly, but private keys must never be exposed.<\/span><\/p>\n<h2><b>How Hot Wallets Operate and Their Advantages<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A hot wallet is a wallet where private keys are stored on an internet-connected device. It can take the form of a mobile application, browser extension, or desktop client.<\/span><\/p>\n<h3><b>Core Characteristics of Hot Wallets<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Private keys are stored on an online device<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Transactions can be signed in real time<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Supports fast transfers<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Facilitates connections to decentralized applications<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Because they remain continuously connected to the internet, hot wallets are well-suited for high-frequency transactions and everyday use.<\/span><\/p>\n<h3><b>Key Advantages of Hot Wallets<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">(1) High Transaction Efficiency<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Users can send assets or interact with smart contracts instantly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">(2) Operational Convenience<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">No complex offline signing procedures are required.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">(3) Strong Compatibility<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Can connect with a wide range of on-chain protocols and applications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">(4) Suitable for Small-Value Asset Management<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Ideal for daily payments or participation in on-chain activities.<\/span><\/p>\n<h2><b>Security Risk Models for Hot Wallets<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While hot wallets offer significant convenience, their primary risk lies in private key exposure within a networked environment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Common risks include:<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> Malware Attacks<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">If a device is infected with trojan programs, attackers may steal private keys or seed phrases.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Browser Extension Theft<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Malicious extensions may read data stored locally.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Phishing Sites<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Users may enter sensitive information on fraudulent pages.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Keyloggers<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Attackers may record private keys or passwords entered by users.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Cloud Backup Leakage<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Automatic backups to cloud services can expose private keys.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">For these reasons, hot wallets are better suited for managing assets within an acceptable risk threshold rather than storing large amounts of value long-term.<\/span><\/p>\n<h2><b>The Core Principle of Self-Custody Wallets<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A self-custody wallet refers to a wallet model where users independently hold control over their private keys.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The fundamental principle is:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Whoever holds the private keys controls the assets.<\/span><\/p>\n<h3><b>Advantages of Self-Custody Wallets<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">No need to trust third parties<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">No risk of platform misappropriation<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not subject to freezes by centralized institutions<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assets remain entirely under user control<\/span><\/li>\n<\/ul>\n<h3><b>Challenges of Self-Custody Wallets<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lost private keys cannot be recovered<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Users bear full security responsibility<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Requires a higher level of security awareness<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A self-custody wallet is not a specific product but rather a model of asset control.<\/span><\/p>\n<h2><b>The Relationship Between Hot Wallets and Self-Custody Wallets<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Many assume hot wallets and self-custody wallets are mutually exclusive, but in practice, they can be used in combination.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the private keys in a hot wallet are fully controlled by the user, that hot wallet also qualifies as a self-custody wallet.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The distinction lies in:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hot wallet emphasizes the online operational mode<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Self-custody wallet emphasizes the ownership of control<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Therefore:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">All non-custodial hot wallets fall under the self-custody category<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not all self-custody wallets are hot wallets<\/span><\/li>\n<\/ul>\n<h2><b>The Role of Public Keys in Security Architecture<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Public keys themselves do not pose a security risk, but they serve critical functions within the overall system.<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> Address Generation Foundation<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Public keys are used to generate blockchain addresses.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Signature Verification Tool<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">All transactions rely on public keys for verification.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Source of Transparency<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Blockchain ledgers are publicly transparent, and all transactions associated with public keys are queryable.<\/span><\/li>\n<\/ol>\n<h2><b>Hot-Cold Segregation: Optimizing Hot Wallet Usage<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">To balance efficiency and security, a hot-cold segregation strategy is commonly adopted.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The structure is as follows:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hot Wallet: Used for daily transactions<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cold Storage: Used for long-term asset preservation<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">This approach:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Limits the risk exposure of hot wallets<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Prevents large-value assets from remaining in online environments<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Enhances overall security<\/span><\/li>\n<\/ul>\n<h2><b>Common Security Misconceptions<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Misconception 1: Public key exposure is dangerous<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">In reality, public keys are designed to be shared openly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Misconception 2: Hot wallets are inherently unsafe<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Security depends on the value of assets held and how the wallet is used.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Misconception 3: Self-custody wallets are simpler<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">In practice, self-custody demands a higher level of security awareness.<\/span><\/p>\n<h2><b>Application in Enterprise-Grade Asset Management<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">For institutional users, hot wallets are primarily used for:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Working capital for operations<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Liquidity management<\/span><\/li>\n<li
