The Securities and Exchange Commission publishes crypto custody guide

Abstract

The U.S. Securities and Exchange Commission (SEC) has published a crypto custody guide outlining best practices and risks for storing digital assets. The bulletin compares self-custody with third-party custody, warning investors to understand policies like asset rehypothecation and commingling. It also details the pros and cons of hot wallets (internet-connected, vulnerable to hacking) and cold wallets (offline, but riskier if keys are lost). The move signals a shift from the SEC’s previously hostile stance under former Chair Gary Gensler. The crypto community welcomed the guide as a transformative step, with some noting the agency is now educating rather than opposing the industry. This follows recent SEC approval for DTCC to begin tokenizing traditional financial assets.

The United States Securities and Exchange Commission (SEC) published a crypto wallet and custody guide investor bulletin on Friday, outlining best practices and common risks of different forms of crypto storage for the investing public.

The SEC’s bulletin lists the benefits and risks of different methods of crypto custody, including self-custody versus allowing a third-party to hold digital assets on behalf of the investor.

If investors choose third-party custody, they should understand the custodian's policies, including whether it “rehypothecates” the assets held in custody by lending them out or if the service provider is commingling client assets in a single pool instead of holding the crypto in segregated customer accounts.

Crypto wallet types were also outlined in the SEC guide, which broke down the pros and cons of hot wallets, which are connected to the internet, and offline storage in cold wallets.

Hot wallets carry the risk of hacking and other cybersecurity threats, according to the SEC, while cold wallets carry the risk of permanent loss if the offline storage fails, a storage device is stolen, or the private keys are compromised.

The SEC’s crypto custody guide highlights the sweeping regulatory change at the agency, which was hostile to digital assets and the crypto industry under former SEC Chairman Gary Gensler’s leadership.

The crypto community celebrates the SEC guide as a transformational change in the agency

“The same agency that spent years trying to kill the industry is now teaching people how to use it,” Truth For the Commoner (TFTC) said in response to the SEC’s crypto custody guide.

The SEC is providing “huge value” to crypto investors by educating prospective crypto holders about custody and best practices, according to Jake Claver, the CEO of Digital Ascension Group, a company that provides services to family offices.

SEC regulators published the guide one day after SEC Chair Paul Atkins said that the legacy financial system is moving onchain.

On Thursday, the SEC gave the green light to the Depository Trust and Clearing Corporation (DTCC), a clearing and settlement company, to begin tokenizing financial assets, including equities, exchange-traded funds (ETFs) and government debt securities.

Telegram Introduces WEB-Proxy Technology: Masks Traffic as Regular Website Visits

Telegram has introduced a new experimental WEB-Proxy technology designed to circumvent blocking by disguising messenger traffic as regular, secure website visits. Announced on August 21, 2026, the technology routes MTProxy data through an in-app WebView using HTTPS or WebSocket transport, making the data stream indistinguishable from legitimate web surfing. The core innovation is a multiplexed stream sent through a single WebView session. It uses special frame formats to pack multiple logical Telegram connections into one encrypted channel that externally resembles loading a web page. A server-side relay receives this stream, separates it into individual connections for the standard MTProxy, without decrypting content or knowing final destinations, thus preserving privacy. The WEB-Proxy operates on a standard HTTPS domain that also hosts a public website. The proxy bridge page is only activated by a specific URL parameter derived via HMAC-SHA256 from the proxy configuration; all other requests receive the normal site homepage. This provides reliable cover against automated detection systems. Currently a proof-of-concept, the system includes a desktop implementation, an experimental Android client, and plans for iOS support. The technology represents a shift towards more sophisticated integration with legitimate web infrastructure, complicating filtering systems that must choose between blocking HTTPS traffic entirely or allowing service access. Its long-term value will depend on resilience to adaptive traffic analysis and scalability without performance loss.

MiCA is coming for DeFi vaults, but regulation will be difficult

The European Commission is exploring whether to extend the Markets in Crypto-Assets (MiCA) regulation to cover decentralized finance (DeFi) lending and borrowing, including lending vaults. These vaults, which channel billions into on-chain credit markets, present significant regulatory challenges because their decentralized structure doesn't map neatly onto existing financial frameworks. Their legal status is currently based on non-binding interpretations that they fall outside MiCA and EU fund rules. The article uses Morpho's decentralized lending protocol as an example, illustrating how responsibilities are divided among various participants (owner, curator, allocator, sentinel), making it difficult to identify a single "provider" to regulate. Experts warn that broadly categorizing "DeFi lending" could inadvertently capture vastly different structures. They argue that any regulatory approach should focus on the specific structure and control mechanisms of a vault, rather than using decentralization as a simple dividing line, and that DeFi lending may require a dedicated, carefully crafted framework distinct from traditional finance. The Commission's consultation closes on September 30, 2026. The core challenge for regulators is not just whether to regulate DeFi lending, but how to design rules that distinguish between different forms of on-chain lending and the entities that control them.

Grayscale Report: Financial Privacy in the AI Era, Why Zcash Should Not Be Overlooked?

Title: Grayscale Report: Financial Privacy in the AI Era – Why Zcash Should Not Be Overlooked The article argues that privacy is a fundamental, not niche, attribute of functional money. It highlights that technological shifts, like the rise of AI and stablecoins, are driving a new wave of public focus on financial privacy. Zcash, a decentralized digital currency similar to Bitcoin but with built-in privacy via zero-knowledge proofs, is positioned to address this need. Unlike transparent blockchains, Zcash offers users the option to conduct "shielded" transactions that hide sender, receiver, and amount while remaining verifiable. The report details Zcash's evolution, noting key upgrades that improved usability and security. It points to rising on-chain usage of privacy features as evidence of real demand. Currently, ZEC holds a minimal share (~0.4%) of the total crypto market cap. Grayscale suggests this reflects a market assumption that privacy is a marginal concern. The investment thesis hinges on a potential market re-evaluation: if privacy is recognized as a core monetary feature in an era of enhanced surveillance, Zcash's current valuation represents significant upside potential. Key risks discussed include regulatory challenges, historical trusted setup concerns for older pools (mitigated by newer protocols), quantum computing threats, and execution risks associated with future technical upgrades. The conclusion is that while the future scale of private digital currency is uncertain, the market currently prices in little chance of its value increasing substantially, presenting a potential opportunity for investors.
