How Can Businesses Prevent Insiders From Moving Crypto Assets?
How can businesses prevent insiders from moving crypto assets? The core principle is that no single person should ever be able to move assets alone. Private keys should be distributed so no one holds a complete key, every transfer should require multi-party approval with initiating, approving, and administering kept as separate roles, rules should be enforced by the system rather than left to individual discipline, every action should leave an auditable trail, and access should be revoked promptly whenever people change roles or leave. Where Does Insider Risk Usually Come From? The most common source is single-person control: a seed phrase kept by a founder or one operations engineer, a hot wallet private key stored on a single server, or one API key that can send transfers on its own. Beyond that, there are three other scenarios: approvers colluding, an employee’s device or account being taken over by an outside attacker who then acts as an insider, and departing employees whose access was never revoked. These are among the risks of crypto custody that are hardest to address with any single technical control. How Can Key Management Prevent One Person From Controlling Assets? The first step is eliminating the complete private key. With an MPC wallet, the key is created as shares spread across different people, devices, and servers, and […]
What Is Fund Sweeping in Crypto?
What is fund sweeping in crypto? It is the process by which exchanges, payment companies, and similar platforms regularly move funds scattered across large numbers of user deposit addresses into a central hot wallet or treasury wallet. After sweeping, the hot wallet covers daily withdrawals, and any surplus moves to cold storage for long-term safekeeping. The main challenges are network fees, timing, and security controls. Why Do Platforms Sweep Funds? Exchanges usually assign each user a dedicated deposit address on each chain so they know exactly who sent each deposit. But funds scattered across thousands of addresses cannot be used directly to pay out withdrawals, and they make reconciliation and risk management more complex. Sweeping concentrates funds in a small number of controlled wallets, making it easier to move money, reconcile balances, and separate hot and cold storage. How Does Fund Sweeping Work? The system first scans the balances of all deposit addresses and picks out those that exceed a threshold and have completed deposit confirmation. It then sends transfers, one by one or in batches, to move the funds to a designated hot wallet. Once the transactions are confirmed on-chain, the swept amounts are reconciled against deposit records. When the hot wallet balance exceeds its cap, the excess is moved to cold storage. Why Is Sweeping Tokens So Difficult? […]
How Do Exchanges Keep Deposit Addresses Secure and Compliant?
How do exchanges keep deposit addresses secure and compliant? On security, they need to do three things: make sure the keys behind the addresses are never concentrated on a single server or in one person’s hands, ensure swept funds can only move to the exchange’s own wallets, and defend against common attacks such as fake token deposits and address poisoning. On compliance, they need to run on-chain risk screening on every incoming deposit, handle Travel Rule information as required, and keep complete records. How Should the Keys Behind Deposit Addresses Be Protected? Exchanges run huge numbers of deposit addresses. If they are all derived from one seed stored on one server, that server becomes the biggest single point of failure in the entire exchange. With an MPC wallet, keys exist only as shares spread across multiple independent nodes from the moment they are generated. Deposit addresses can still be created in bulk, while sweep transactions require several shares to sign together, so compromising one server is not enough to move funds. Combined with a Trusted Execution Environment (TEE) as part of a layered security architecture, the shares can be isolated even further. How Can Exchanges Stop Swept Funds From Being Stolen? Sweeping is the most frequent operation on deposit addresses, which makes it the step attackers most want to hijack. […]
How Do Crypto Exchanges Manage Deposit Addresses?
How do crypto exchanges manage deposit addresses? Typically, they assign each user a dedicated deposit address on each chain, monitor incoming transactions and credit them once they reach the required confirmations, then regularly sweep funds scattered across these addresses into a hot wallet, moving any surplus to cold storage. Throughout the process, exchanges also screen incoming funds for anti-money laundering risk and protect the keys behind every address. How Do Exchanges Generate Deposit Addresses for Users? The mainstream approach is one address per user: the system automatically derives a dedicated address for each user on each chain, so when a deposit arrives, the address alone tells you whose money it is. An exchange may have hundreds of thousands of users across dozens of chains, so the number of addresses quickly reaches the millions. Addresses therefore need to be generated in bulk and on demand, rather than storing a separate private key for each one. Some chains, such as XRP and TON, use a shared address with a memo instead. All users deposit to the same address and are told apart by a memo or tag. The most common problem on these chains is users forgetting or mistyping the memo, so exchanges need a dedicated process to handle these unattributed deposits. How Do Exchanges Confirm a Deposit Before Crediting It? Exchanges […]
What Are the Risks of EIP-7702?
What are the risks of EIP-7702? There are five main ones: users being tricked into signing malicious delegations, authorizations without a fixed chain ID being replayed on other chains, the original private key remaining a single point of failure that can bypass every rule if leaked, bugs in the delegated contract itself, and older contracts’ assumptions about ordinary addresses no longer holding. EIP-7702 brings the convenience of smart accounts, and it brings these risks to everyday users too. Why Are Malicious Delegations So Dangerous? Under EIP-7702, a delegation the user signs makes their address run another contract’s code, and that code has the same authority as the address owner. If the delegate is a contract written by an attacker, every token and NFT at the address can be drained at once, and the delegation stays in effect until the user revokes it. Because signing an authorization looks much like any other signature request, users find it hard to spot the danger. Since the Pectra upgrade, attackers have already used malicious delegations to steal assets at scale. What Is the Cross-Chain Replay Risk in EIP-7702? An authorization can specify a chain ID. If the chain ID is set to 0, the authorization is valid on every EVM chain that supports EIP-7702. The same contract address does not necessarily hold the same […]
