SPCXx 由受监管托管的真实 SpaceX 股票以 1:1 的比例比例支持。本文介绍了该安排的操作详情：股票存放的地点、监管人是谁、如何验证支持以及在发生问题时该结构的旨在如何运作。如果您想从基础知识开始，有关 SpaceX xStock 代币结构方式的配套文章解释了 1:1 支持在实践中的含义。
核心观点：
标的资产 SpaceX 股票由 Alpaca Securities LLC（受 FINRA 监管，SIPC 成员）存放在隔离的子账户中。Incore Bank 担任备用托管人。
三方账户控制协议赋予独立的担保代理人在代币持有者权利未得到维护时接管托管账户的权力。
该结构的设计使得代币持有者的索赔与托管的标的资产估值挂钩，而不是被视为对发行人的无担保索赔。实际结果取决于产品条款和法律程序。
The SpaceX shares backing SPCXx tokens are held by Alpaca Securities LLC, a US broker-dealer regulated by FINRA and a member of SIPC.A few things to understand about this setup:
Alpaca is a regulated institution. FINRA regulation means Alpaca operates under defined compliance and operational standards. SIPC membership relates to Alpaca's regulated brokerage activities, though it does not specifically cover SPCXx token holders against token losses, market losses or issuer failure.
Incore Bank serves as backup custodian. If the primary custody arrangement is disrupted, Incore Bank provides a secondary layer of custodial continuity.
Accounts are segregated. Each xStocks product has its own dedicated sub-account with no commingling between products. The shares backing SPCXx are held separately from those backing any other token. This helps prevent issues with one product from affecting another product’s custody pool.
Custody alone is not enough. Someone needs to verify that the custodian is doing its job and that the shares remain where they should be. This is where the Account Control Agreement (ACA) comes in.The ACA is a three-party contract between:
Backed Assets (JE) Limited (the issuer of SPCXx tokens)
Alpaca Securities LLC (the custodian holding the shares)
An independent Security Agent (a third party with oversight powers)The Security Agent has visibility over all collateral accounts. Its job is to monitor whether token holder rights, as defined in the approved product prospectus, are being upheld. If it determines those rights are being violated, it has the contractual authority to take control of the custody accounts, independently of the issuer.This is significant because it means oversight does not depend on the issuer policing itself. There is an independent party with the power to intervene if things go wrong.
Two mechanisms provide verification:
Quarterly ISAE 3000 audits. An independent auditor checks whether each on-chain SPCXx token has a corresponding real share held in custody. This is done asset-by-asset with no netting across products. The ISAE 3000 standard is an internationally recognized assurance framework, so this is not a self-reported claim from the issuer.
Live proof of reserves. Between quarterly audits, proof of reserves is published via the xStocks Dashboard. This is publicly accessible, giving users a way to review whether on-chain supply matches custodied shares at any point.Together, these mechanisms provide both periodic formal verification (audits) and ongoing informal transparency (proof of reserves).
The custody arrangement uses an SPV structure designed with bankruptcy isolation in mind. The aim is straightforward: if Backed Assets (JE) Limited faced financial distress, token holder claims should be linked to the underlying asset value held in custody, rather than leaving token holders as general unsecured creditors competing with all of the issuer's other obligations.
The Security Agent provides an additional enforcement mechanism in this scenario. It can take control of the custody accounts independently, meaning the shares do not necessarily become entangled in the issuer's insolvency proceedings.
However, there is an important caveat: structural design and actual legal outcomes are not the same thing. The protections described above represent how the arrangement is built, but actual recovery in a real failure scenario would depend on the specific circumstances, the full product terms and applicable legal proceedings in the relevant jurisdiction. The structure does not guarantee recovery.
Understanding boundaries is as important as understanding protections:
You hold economic exposure, not direct shares. SPCXx does not give you voting rights, shareholder registration or shareholder-style dividends. If dividends or other corporate actions apply, their value is reflected through the product mechanism, such as reinvestment, rebasing or token airdrops.
Token prices can diverge from underlying share value. Market dynamics, liquidity conditions and trading activity can cause SPCXx to trade at a premium or discount to the underlying.
The structure depends on multiple parties. Alpaca Securities, Backed Assets and the Security Agent all need to continue operating as designed for the protections to function.
Legal enforceability may vary by jurisdiction. Users in different regions may face different legal landscapes in the event of a dispute or distress scenario.
This is not the same as a personal brokerage account. Holding SPCXx is structurally different from holding SpaceX shares directly through a traditional broker.
SPCXx 由一个托管结构提供支持，该结构包括一个受 FINRA 监管的托管人、隔离账户、一个备用托管人、季度 ISAE 3000 审计、实时准备金证明以及三方账户控制协议下的独立安全代理。
这些层旨在支持 xStocks 结构内的监督、验证和执行。它们具有意义，但并非安全或恢复的保证。用戶获得的是经济敞口，而非直接股份所有权，且在压力情况下的结果取决于产品条款、适用法律以及相关方的持续运营。
