Zerohash launched AUTH on Monday, October 19, offering a way to move digital assets between linked accounts without asking users to copy a wallet address or choose a blockchain network. The Chicago-based infrastructure company announced the product at Money20/20 USA in Las Vegas. It is aimed at the exchanges, brokerages and financial apps that embed Zerohash services, rather than being a standalone consumer wallet.

The change is in the transfer interface, not the underlying settlement method. A user selects a supported custodial account or self-custody wallet, completes that provider's authentication steps and approves the movement of an available asset. Zerohash says the asset still moves onchain while AUTH handles account linking and routing behind the scenes. Its developer documentation says the flow can be used for deposits and withdrawals, including transfers that leave a customer's balance in crypto or convert it into a fiat balance on the receiving platform.

A narrower promise than universal transfers

Zerohash says AUTH has more than 600 connections across wallets and custodial accounts, naming Coinbase, Gemini, Robinhood, MetaMask and Phantom among examples. A connection count is not the same as a promise that every asset can travel between every pair of accounts. Each integrating platform chooses which accounts, assets, networks and transfer types it permits. CoinDesk independently reported the launch and noted that some named exchange or brokerage connections were live while another was in beta.

That distinction matters for users. Someone may be able to link a wallet but still find a particular token or direction of transfer unavailable in an app. Zerohash's product page also says a traditional address-based transfer can remain an option where AUTH does not support an account, or where a user prefers the older workflow. The firm has not supplied a public transaction-volume figure for AUTH, so the announcement alone does not show how widely customers are using it.

Why account linking matters

Crypto withdrawals commonly require a sender to paste a long destination address and select the correct network. An error can be hard to reverse after a transaction settles. AUTH tries to move those decisions into a verified connection and a user approval step. The product documentation says existing account security, including multifactor authentication when required, remains part of linking and transfer authorization. That may reduce manual mistakes, but it does not eliminate the need to check the asset, recipient account, permissions and transaction details before approving a transfer.

For brokerages and payment providers, the service is another attempt to make crypto movement resemble familiar account-to-account payments while retaining onchain settlement. The company says the same interface can support stablecoins and tokenized securities as well as other crypto assets. Whether it improves completion rates or lowers support costs will depend on actual integrations and customer use; those outcomes have not been independently demonstrated in Monday's announcement.

Access and limits

Zerohash's release says its services may not be available in every jurisdiction, including New York, and that its accounts do not carry FDIC or SIPC protection. AUTH is secured by Connect Ltd., a Bermuda affiliate, according to the company's disclosure. Financial apps considering the tool therefore still have to decide where they can offer it and what compliance controls apply. Users will see only the connections and transfer options their particular app enables.

The immediate verified development is the product launch and published integration documentation. It does not mean transfers are automatically available across every advertised wallet or market. The practical test will be which platforms activate AUTH, what assets they enable and whether the account-linked flow performs reliably when customers move funds.
