Spot trading, retirement accounts and order interfaces
Sections ↑Public offers spot crypto through its investment interface, with execution and custody supplied by zerohash, in a distinct account from securities brokerage.[1]
Trading routes and account scope
| Route | Current published offering | Boundary |
|---|---|---|
| Standard crypto | The product page describes more than 60 assets, market and limit orders, and recurring purchases. | Minimum purchase USD 1; maximum single order USD 100,000 and aggregate open orders USD 200,000.Source 1 |
| Trading hours | The December 2025 trading-hours page describes 24-hour access. | This is service availability, not an assurance of continuous quotes or fills.Source 6 |
| Crypto IRA | Traditional and Roth crypto IRAs offered and custodied by Alto Trust Co. | Separate from a Public Investing/Apex securities IRA.Source 18 |
| Programmatic access | The Public API supports crypto alongside other asset classes. | Crypto transaction fees apply despite zero-commission language elsewhere about securities.Source 22 |
The published order rules require some care. An October 2025 help article still describes daily maintenance cancellation, while the migration notice says the zerohash move removed that maintenance window and added order-expiration customization. The newer trading-hours page supports 24-hour access. The old daily expiry should not be treated as the current universal order rule.[5][7][6]
API submissions are asynchronous: receiving an order identifier confirms submission, not a fill or even immediate visibility in every view. The documentation directs clients to query the order-status endpoint afterward. This is particularly relevant before submitting a replacement instruction after an uncertain response.[29]
Retail, recurring-order and API fees
Sections ↑Standard app/web crypto transaction tariff
| Order amount | Published maximum transaction fee |
|---|---|
| USD 0.01–10.00 | USD 0.49 |
| USD 10.01–25.00 | USD 0.69 |
| USD 25.01–50.00 | USD 1.19 |
| USD 50.01–100.00 | USD 1.69 |
| USD 100.01–250.00 | USD 3.29 |
| USD 250.01–500.00 | USD 6.29 |
| Above USD 500 | 1.25% of the order |
| Recurring Investment Plan order | 1.25%, regardless of amount |
For example, a USD 200 standard order has a published USD 3.29 maximum fee; a USD 200 recurring order costs USD 2.50 at 1.25%. A USD 2,000 order at 1.25% costs USD 25. The route matters as well as the amount. These are fee calculations, not a comparison of executable prices.[2]
API and Agentic API crypto tariff
| Monthly executed crypto volume | Fee rate |
|---|---|
| USD 0–10,000 | 0.60% |
| USD 10,000–50,000 | 0.50% |
| USD 50,000–100,000 | 0.40% |
| USD 100,000–1 million | 0.30% |
| USD 1–15 million | 0.20% |
| USD 15–100 million | 0.15% |
| USD 100 million+ | 0.10% |
Once a new API tier is reached, the fee schedule retains that rate through the end of the following calendar month. At the initial 0.60% tier, a USD 2,000 order costs USD 12. This schedule applies to the named API routes; it should not be applied to an ordinary app order merely because the same customer also has an API key.[3]
The dedicated Crypto IRA fee page describes a dynamic transaction charge of at least 1.25%, plus custody of 0.05% monthly, accrued daily. Transaction charges offset that month’s custody fee; Reserve members have the custody fee waived. For a constant USD 20,000 balance, the monthly custody calculation is USD 10 before credits; USD 6 of eligible transaction charges would leave USD 4. The current fee schedule should be checked alongside the IRA quote.[19]
Brokerage cash, wallet transfers and withdrawal timing
Sections ↑Funding and withdrawal mechanics
| Route | Documented process | Important restriction |
|---|---|---|
| Buying with cash | Purchase money moves from Public Investing brokerage to the zerohash account. | Crypto and securities use distinct account relationships.Source 8 |
| Selling for cash | Sale proceeds return to the brokerage account. | The crypto withdrawal help says cash is typically withdrawable after two full business days.Source 9 |
| New bank deposits | Buying power can precede withdrawal eligibility; standard deposit settlement is three business days. | Amounts above USD 55,000 deposited within six business days have a six-business-day settlement period.Source 10 |
| Crypto transfers | Supported assets can move in and out through zerohash; contact support to begin. | New York members cannot transfer crypto.Source 4 |
| Withdrawal cost and network | Public charges no transfer fee; outgoing network charges include a USD 0.53 zerohash KYT fee. | The transfer guide specifies Ethereum mainnet only for ETH; unsupported networks are not received.Source 4 |
The cash balance and buying-power figures answer different questions. Cash can include funds still settling, while buying power describes funds available for purchases. Neither figure should be assumed to mean the full amount is immediately available to withdraw to a bank.[10]
Custody, protection limits and account security
Sections ↑Public’s March 2026 risk disclosure says crypto remains the customer’s property and describes an Article 8 security-entitlement structure. For the standard account, zerohash is the intermediary; the Crypto IRA adds Alto between the customer and zerohash. The disclosure excludes crypto from FDIC and SIPC protection and retains exposure to custodian operational and credit risk.[17]
Custody and account safeguards
| Issue | Published treatment | Limit |
|---|---|---|
| Key control | Crypto is held by zerohash through the account service. | This is custodial ownership, not possession of a private seed phrase.Source 1 |
| Margin and short selling | Crypto has no margin collateral value; sales require assets already owned. | A securities margin account does not create leveraged crypto trading rights.Source 17 |
| Login protection | Public describes SMS two-factor authentication, encryption and optional device biometrics. | Protecting device access remains the customer’s responsibility.Source 13 |
| Withdrawal review | Transfers to a different bank account than the original depositing account can receive additional review. | A change of destination may affect cash access.Source 13 |
If access is lost or an account appears compromised, Public directs customers to [email protected] for verification and recovery. The reviewed guidance did not establish a universal crypto withdrawal delay after every password or device change. It would be inaccurate to substitute an assumed fixed hold for the account’s actual review status.[13]
Eligibility, location and account boundaries
Sections ↑Who can use the service
| Requirement | Published position | Qualification |
|---|---|---|
| Public account | Age 18 or above, valid SSN, legal US residential address and US citizenship, permanent residency or a valid visa. | Additional identity documents may be requested.Source 11 |
| Physical location | Crypto access is described for Public US customers physically in the US. | Travel can restrict access even when the account remains US-based.Source 12 |
| Travel examples | The restriction list includes the UK, Germany, Italy, Spain, Japan and Hong Kong, among others. | The provider can change the list; it is not a worldwide-access promise.Source 12 |
| New York transfers | New York members cannot send or receive crypto through the documented transfer route. | A trading entitlement does not establish transfer eligibility.Source 4 |
Member support and complaints
Sections ↑Help and escalation
| Need | Published contact | Boundary |
|---|---|---|
| Account or trading help | In-app chat or [email protected]. | The contact FAQ says Public does not offer phone support.Source 14 |
| Locked-out account | Email [email protected] for identity verification. | No guaranteed response time is stated on the page.Source 14 |
| API integration | [email protected]. | Developer assistance does not guarantee order execution.Source 22 |
| zerohash complaint | +1 855 744 7333; New York complaints can also go to NYDFS. | This is complaint escalation, not a Public telephone dealing route.Source 16 |
Exchange, intermediary or custodian interruptions can prevent crypto access; continuous quotes are not guaranteed.[17]
Which entity provides which service
Sections ↑NYDFS lists zerohash llc with virtual-currency and money-transmitter licences, and zerohash liquidity services llc with a virtual-currency licence. These entries support the named providers’ New York permissions. They do not make Public’s crypto account a SIPC-covered securities account.[15]
The crypto disclosure identifies Public Platform LLC for the standard zerohash account and Public Holdings, Inc. for the Alto account context.[17]
The IRA product names Alto Trust Co., a New Mexico trust company, as its provider and custodian. Use the agreement for the account actually opened when comparing custody and promotions.[18]
Service history and provider migration
Sections ↑Public’s September 2025 migration notice scheduled the transfer of its Bakkt crypto relationship to zerohash for 24–26 October 2025. It said balances would transfer without a migration fee and customers would accept the new provider’s terms before resuming. The current product and September 2026 transfer help identify zerohash, so older Bakkt-era instructions should be read in that historical context.[7]
A current crypto-only active-customer count or trading-volume figure was not established.[1]

Records, automated authority, promotions and closure
Sections ↑The crypto tax help explains that customers trading during the provider transition may receive separate 2025 Form 1099-DA documents from Bakkt and zerohash. Those documents are available in the app. The page’s cost-basis reporting discussion is expressly about the 2025 tax year; it should not be copied forward as a statement of later-year reporting rules.[28]
Automation and continuing authority
| Feature | Documented control | Customer responsibility |
|---|---|---|
| Personal API | Generate a secret in account settings and exchange it for an access token. | The token authenticates account requests; credentials must remain private.Source 23 |
| Hosted MCP | Connect a supported AI client to Public using the published setup. | A trade placed through the connector is a real-money order; review the preflight details.Source 24 |
| Native AI Agents | Customers review and activate a workflow; crypto instructions are passed to zerohash. | Once activated, recurring/conditional transactions run without fresh confirmation for each action.Source 25 |
| Stopping an Agent | An Agent remains active until paused or terminated. | The customer must monitor it; completed trades cannot be reversed merely by stopping the workflow.Source 25 |
This automation has actual order authority, rather than being limited to research summaries. Public’s disclosure says generated information can be wrong and execution time or price is not assured. Customers remain responsible for reviewing the workflow before activation and for modifying or stopping it when their intentions change.[25]
The Crypto IRA page advertises a 1% match, but the agreement it links defines its covered IRA as Public Investing’s Apex-custodied account. That does not establish the terms of Alto’s Crypto IRA. The profile therefore does not treat that advertised benefit as an unconditional or immediately withdrawable cash reward. Crypto IRA-specific terms require confirmation.[18][20]
A separate external-wallet crypto-transfer promotion is explicitly marked expired on 31 May 2026. Its older 1% cash-match language remains on the help page, but the expiry label prevents treating it as a current offer.[21]
Public’s inactivity fee is a brokerage-account charge: USD 3.99 monthly for accounts below USD 70 with no activity for six months. Its help says a login at least every 180 days avoids the inactivity condition. This is different from closing the crypto account or cancelling recurring instructions.[26]
Crypto does not move through a securities ACATS transfer. Public says requesting a full outgoing brokerage transfer freezes the account while crypto remains, and customers must contact support to retain, sell or separately transfer those holdings. Recurring deposits and investment plans should be addressed before a full transfer; moving the securities alone does not finish the crypto exit.[27]
