# USDT (USD-Equivalent) Valuation Risk

{% hint style="info" %}
Operator and jurisdiction: BASIS is operated by BASIS DIGITAL INFRASTRUCTURE LTD, a Seychelles IBC (LEI: [254900IX2F2KCWNSSS64](https://lei.bloomberg.com/leis/view/254900IX2F2KCWNSSS64)).

Research Partner: Base58 Labs contributes execution research, systems modeling, and risk design.
{% endhint %}

BASIS uses USDT as a primary unit of account for valuation display. This creates a distinct risk category: valuation basis risk. This page explains what that means and how the platform manages it.

## 1. What "USD-Equivalent" Means in BASIS

BASIS may report values, thresholds, and performance figures in USDT as a USD-equivalent reference. Users should understand the following distinctions:

* USDT is a stablecoin, not sovereign currency.
* USDT may deviate from 1 USD in secondary markets.
* Liquidity or redemption conditions may become impaired during market stress.
* Displayed USDT-equivalent values are accounting references, not a guarantee of fiat conversion at par.

{% hint style="warning" %}
USDT cannot be deposited to or withdrawn from BASIS.

Deposits and withdrawals use native assets only:

* BTC
* ETH
* SOL
* PAXG
  {% endhint %}

When the platform shows a USD-equivalent balance, that figure is a reference valuation. The realizable value of any position depends on the market value of the underlying native asset or stToken at the time of withdrawal, swap, or external conversion.

## 2. Why Stablecoin Deviation Matters

If USDT deviates from USD, displayed valuations across the platform may temporarily diverge from fiat expectations.

### Impact on platform valuation

* Reference balances shown in USDT-equivalent terms may not match USD purchasing power exactly.
* Historical performance metrics normalized to USDT may reflect stablecoin basis movement in addition to asset performance.
* Cross-venue pricing relationships may become noisier during stress periods.

### Impact on user interpretation

* A displayed balance expressed in USDT-equivalent terms is not the same as holding fiat USD.
* Reward values interpreted through a USDT lens may appear higher or lower relative to USD during a deviation event.
* External conversion outcomes depend on the asset withdrawn and prevailing market conditions.

## 3. Historical Deviation Examples

| Date         | Trigger                        | USDT Low | Recovery Time |
| ------------ | ------------------------------ | -------- | ------------- |
| October 2018 | Market panic, reserve concerns | \~$0.925 | \~48 hours    |
| May 2022     | Broad market contagion         | \~$0.955 | \~72 hours    |
| March 2023   | Banking system stress          | \~$0.975 | \~24 hours    |

These events recovered within days, but temporary deviations were material enough to affect valuation references and user expectations.

## 4. Protective Response Design

BASIS applies a tiered monitoring and control framework for stablecoin valuation stress.

### Tier 1: Monitoring (< 0.5% deviation)

* Continuous monitoring across multiple market data sources
* No intervention required
* Normal valuation fluctuation

### Tier 2: Alert (0.5% - 1.0%)

* Operations alert generated
* Increased surveillance on valuation inputs
* Tighter review of displayed conversion assumptions

### Tier 3: Control State (1.0% - 3.0%)

* USDT-sensitive valuation logic reviewed
* New risk-taking may be reduced where valuation basis becomes unstable
* Internal controls tightened across settlement-dependent processes

### Tier 4: Defensive Mode (> 3.0%)

* Protective controls escalated
* Capital preservation protocols engaged
* Public status communication issued where relevant
* System behavior prioritized for orderly operation and deterministic execution

{% hint style="info" %}
BASIS risk controls are built around deterministic execution, mathematical constraints, and state-machine based operational safeguards.

This framework supports orderly behavior under valuation stress and aligns with BASIS structural alpha capture infrastructure.
{% endhint %}

## 5. User Guidance

Users should:

* Understand that USDT is a reference unit, not fiat USD
* Treat displayed USDT-equivalent values as accounting outputs
* Evaluate the underlying asset exposure separately from the display denomination
* Review platform notices during periods of market stress
* Keep records of entry value, withdrawal value, and external conversion rates for their own accounting

## 6. Product Context

BASIS wallet behavior is structured as follows:

| Wallet         | Asset Type    | Function                                             |
| -------------- | ------------- | ---------------------------------------------------- |
| Funding Wallet | Native tokens | Deposit and withdraw BTC, ETH, SOL, PAXG             |
| Staking Wallet | stTokens      | Hold stBTC, stETH, stSOL, stPAXG and receive rewards |

### Deposit model

{% tabs %}
{% tab title="BTC" %}

* Copy your BASIS-assigned BTC deposit address
* Each account receives a unique BTC address
* No Web3 wallet connection is required
* Minimum deposit: 0.0001 BTC
  {% endtab %}

{% tab title="ETH / SOL / PAXG" %}

* Connect a supported Web3 wallet such as MetaMask
* Deposit native ETH, SOL, or PAXG to your Funding Wallet
* PAXG support is live and active
  {% endtab %}
  {% endtabs %}

### Swap model

Swaps are same-token only at 1:1 conversion:

| Native Token | stToken |
| ------------ | ------- |
| BTC          | stBTC   |
| ETH          | stETH   |
| SOL          | stSOL   |
| PAXG         | stPAXG  |

Fee schedule:

| Action     | Fee   |
| ---------- | ----- |
| Deposit    | 0%    |
| Withdrawal | 0.05% |
| Swap       | 0.01% |

### Withdrawal timing

| Asset Group      | Typical Time     |
| ---------------- | ---------------- |
| BTC              | 10 to 60 minutes |
| ETH / SOL / PAXG | 1 - 6 min        |

## 7. Infrastructure Context

BASIS execution systems are designed for execution precision and structural alpha capture.

Key operating characteristics include:

* Seychelles IBC operating entity
* LEI: [254900IX2F2KCWNSSS64](https://lei.bloomberg.com/leis/view/254900IX2F2KCWNSSS64)
* Research support from Base58 Labs as Research Partner
* BHLE architecture with sub-50μs latency
* 100K+ OPS routing infrastructure
* Deterministic execution pathways
* State-machine risk controls
* Mathematical constraint enforcement

These controls do not eliminate valuation basis risk, but they improve operational consistency during stressed market conditions.
