# Launching Institutional afi-rwaUSDi Vault

AFI is introducing the **afi-rwaUSDi Institutional Vault**, a dedicated Proof-Of-Reserve vault backed by less liquid assets like market-neutral funds, private credit, etc.\
\
This vault represents the first institutional deployment of AFI’s **on-chain reserve verification framework**, enabling regulated issuers to bring real-world collateral on-chain with transparent, mathematically enforced backing.\
\
rwaUSDi asset is issued by [Multipli](https://multipli.fi/).

***

### **Overview**

The afi-rwaUSDi Vault is built to solve the core challenge of RWA integration:

> **Off-chain collateral cannot be verified or enforced by smart contracts.**

By locking rwaUSDi inside an ERC-4626 PoR Vault and minting **afi-rwaUSDi** as the on-chain receipt token, AFI creates a **provable, deterministic link** between:

1. **Less liquid assets like** market-neutral funds, private credit, etc.
2. **Tokenized rwaUSDi supply**
3. **Circulating afi-rwaUSDi in DeFi**

This transforms gold-backed assets from *issuer-dependent claims* into **cryptographically verifiable collateral**, suitable for institutional deployment across DeFi.

***

## **Vault Architecture**

#### **1. Reserve Tokenization (Off-Chain → On-Chain)**

The Assessed Entities hold a diversified pool of assets, including cash reserves, fund investments, strategic equity positions, and income-generating real-world operating assets.\
These reserves are tokenized as **rwaUSDi**, where:

* 1 rwaUSDi = $1 backed by market-neutral funds, private credit etc
* Backing is attested by custodians and independent auditors
* Supply reflects real-world gold holdings

***

#### **2. Locked Collateral (On-Chain POR Vault)**

The issuer deposits **100% of their rwaUSDi supply** into the AFI Proof-Of-Reserve Vault.\
The vault enforces:

```
afi-rwaUSDi supply ≤ rwaUSDi locked in vault
```

rwaUSDi becomes **non-circulating collateral**, fully visible on-chain.

***

#### **3. Minting of Institutional Receipt Token (afi-rwaUSDi)**

For every rwaUSDi deposited, the vault mints **1 afi-rwaUSDi**, a clean ERC-4626 receipt token engineered for DeFi composability.

afi-rwaUSDi is the **circulating asset**, that can be used by:

* Institutional treasuries
* DeFi lending protocols
* Liquidity pools
* Market makers
* Cross-chain integrations

This token is always provably backed by gold reserves.

***

## **Why This Structure Is Needed**

#### **1. RWA tokens are opaque by default**

Most RWA issuers publish reserve reports via PDFs, legal attestations, or monthly audits.\
These mechanisms cannot be read or trusted by smart contracts.

afi-rwaUSDi solves this by binding reserve backing to **on-chain enforcement**, not delayed documentation.

***

#### **2. On-chain solvency requires real-time constraints**

afi-rwaUSD cannot be over-minted or under-backed.\
The vault mathematically enforces full collateralization at the contract level:

* No entity can increase circulating supply
* No reserves can be silently redeployed
* No fractional exposure can occur
* No recursive minting (like xUSD) is possible

All supply changes require collateral deposits and are visible in real time.

***

#### **3. DeFi requires verifiable collateral—not issuer promises**

Protocols such as Aave, Morpho, Curve, Pendle, and money-market primitives cannot rely on off-chain trust.\
They require **deterministic invariants**, such as:

```
Circulating Tokens ≤ Verified Reserves
```

afi-rwaUSD provides this guarantee natively.

***

## **Flow Summary**

#### **Without AFI**

```
Real World Assets → Custodian → Issuer → rwaUSDi → DeFi (Unverified)
```

#### **With AFI Proof-of-Reserve**

```
Real World Assets → Custodian → rwaUSD → AFI PoR Vault → afi-rwaUSDi → DeFi (Verified)
```

afi-rwaUSDi is the first **institutional-grade, provably backed, composable RWA stablecoin**.
