How Street works, in the order you'll meet it: verification, markets, orders, settlement, lending, and custody, plus what issuers put in place at listing.

01 · Overview

What Street is

Street is a market for private company securities, built as one connected system: Liquid runs the order book, Heimdall executes and supervises, Mimir keeps the ownership record, and custody holds positions directly. This page documents how those pieces behave from a participant's point of view.

The four functions

FunctionWhat it does
Liquid · trading venueRuns a continuous limit order book per listed security, inside guardrails the issuer sets at listing.
Heimdall · executionRuns every order through pre-trade checks and executes matches as riskless principal, both sides at one on-screen price.
Mimir · ownership recordKeeps the book-entry register. Fills write to it directly, so settlement is a record update, not a paperwork workflow.
CustodyHolds positions as direct beneficial ownership between holder and issuer, no pooled vehicle in between.

The one rule everything follows

Conditions are checked before an order exists, not after a match. Identity, accreditation, issuer consent, and transfer restrictions are all order-entry conditions. If a check fails, the order never reaches the book, which is why an order that rests on Liquid is an order that can settle.

02 · Accounts

Accounts & verification

Every account is verified before it can see a market. What you bring depends on your role.

What each role provides

RoleVerification requirements
ShareholderIdentity verification, accreditation evidence, and proof of your holding in the company. Once cleared, your position is recorded on the Mimir register and you can route it: sell on-book, lend through Street Lending, or hold.
InvestorIdentity verification and accreditation evidence. Securities on Street are offered exclusively to accredited investors, so verification is the gate to the order book.
IssuerEntity documents: board authorization, transfer pre-consent, a ROFR waiver, and a resale disclosure package: secured once, at listing.

The review process

Submit your materials and the Street team reviews them, following up if anything is missing. Once review clears, your account is activated for its role. Verification is not a one-off formality: accreditation status is part of every pre-trade check your orders pass through.

To begin, email secondaries@street.app— we’ll respond with the verification checklist for your role.

03 · Markets

Markets on Liquid

Each listed security trades in its own market: a continuous limit order book that opens with issuer consent and runs inside issuer-set guardrails.

How a market opens

StageWhat happens
ListThe issuer authorizes the security for trading and sets the market's rules, who may hold, how price may move, what must be disclosed.
QuoteVerified participants place firm limit orders into the book. Resting interest is real, priced, and visible.
MatchCrossing orders fill at one on-screen price, as riskless-principal matches through the broker-dealer.
PrintExecutions write straight to the Mimir register, the market's record and the issuer's record never diverge.

Issuer guardrails

Guardrails are rules the issuer sets once, at listing, and the venue enforces on every order, not terms renegotiated per trade. They typically include price bands (a floor and ceiling within which orders may rest) and trading windows (when the market is open). An order outside the band is rejected at entry; there is no override path.

What you see on screen

A live book: resting bids and asks at firm prices with visible size, the current spread, and the session’s prints. Depth is on screen before you trade, liquidity is not discovered after the fact through a broker chain.

04 · Orders

Orders & execution

Liquid takes firm limit orders. Every order passes the same pre-trade checks, in line, before it can rest on the book.

Order types

The book is built on limit orders: a price and a size, firm until filled or cancelled. Orders rest openly on the book and fill when a crossing order arrives. There is no negotiated-block side channel. The book is the market.

Pre-trade checks

CheckWhat it verifies
IdentityThe account belongs to a verified person or entity (KYC).
AccreditationThe buyer currently meets the accredited-investor standard.
Issuer consentThe issuer's transfer pre-consent covers this security and transfer.
RestrictionsTransfer restrictions and ROFR status are clear, per the issuer's listing terms.
GuardrailsThe order sits inside the issuer's price band and trading window.

A failed check stops that one order and routes it to review. It does not slow the rest of the book.

Execution

Matches execute as riskless principal through the broker-dealer: both sides trade at the same on-screen price, and the fill prints to the tape with a timestamped, attributable record.

05 · Settlement

Settlement & recordkeeping

Settlement on Street is a register update. Because execution and recordkeeping share one system, there is no reconciliation step between 'the trade happened' and 'the books say so.'

From fill to record

StepWhat happens
FillA match executes on Liquid at one price.
WriteThe fill writes directly to the Mimir book-entry register, seller position down, buyer position up.
VersionThe register versions the change with full lineage: what moved, when, under which consents.
ConfirmBoth parties see the updated position; the issuer's record is the same record.

Reading your position

Your holding is a book-entry position on the register, in your name, updated in real time. What you see is not a statement generated from a downstream copy. It is the record itself, continuously reconciled against shares issued and outstanding.

06 · Lending

Street Lending

Street Lending is the alternative to selling: lend shares against cash collateral and keep your exposure to the company.

How it works

A holder lends shares and receives cash against them. The position is lent, not disposed of. The structure is designed to provide liquidity without selling the position, and the holder keeps economic exposure while accessing cash.

What to check before borrowing

The treatment of any lending arrangement depends on its specific terms and your individual circumstances. Street does not provide tax advice, consult your own tax adviser before borrowing against a position, and see the liquidity paths guide for how selling, lending, and holding compare.

07 · Custody

Custody

What you hold on Street is the security itself, in your name.

Direct beneficial ownership

Positions are held as direct beneficial ownership between the holder and the issuer, no pooled vehicle or fund structure sits in between. Recordkeeping and safeguarding are handled by the platform’s register, and the ownership chain has exactly two ends: you and the company.

Details of the custody model and its safeguards are covered on the security page, and the custody function is part of the registrations currently in progress.

08 · Issuers

For issuers

A listing is a one-time setup that makes every subsequent trade in your security routine. Four things go in place, once.

The listing package

ItemWhy it exists
Board authorizationThe market in your security exists because you approved it, authorization is the foundation of everything on Street.
Transfer pre-consentEach transfer doesn't require a fresh approval cycle; consent is granted at the ruleset level.
ROFR waiverMatched trades aren't unwound after the fact by a right of first refusal.
Resale disclosure packageBuyers trade on issuer-provided information, not rumor.

Ongoing control

Listing is not a loss of control. It is control, encoded. Guardrails (price bands, trading windows, holder eligibility) are yours to set, the venue enforces them on every order, and your register is always current because fills write to it directly.

09 · Status

Availability & status

A straight answer about what exists today.

Where the platform stands

Street is in early access. The regulated functions this documentation describes — broker-dealer execution, the transfer-agent register, and the alternative trading system — have registrations in progress, pending regulatory approval, and the platform operates accordingly until they are granted. Documentation is written against the platform as designed, so participants know exactly what they are onboarding toward.
