vyUSD, issued by YieldFi, is a tokenized vault product evidencing a contractual claim on a market-neutral yield strategy, structured as a Series-limited, limited-recourse debt instrument whose Net Asset Value (NAV) accrues as underlying yield is realized [S1][S2][S3].

Each vyUSD token represents a pro-rata contractual claim on a dedicated vault deploying its Series Assets into yield-generating strategies, with returns reflected in a rising exchange rate rather than distributions [S2][S4]. Positive NAV updates vest over an epoch of approximately 24 hours to deter yield-sniping, while negative performance applies immediately [S2][S4]. Holders bear vault-specific management, performance, deposit, and withdrawal fees applied under the Series Waterfall before redemption, with exact figures on each vault factsheet [S5][S3].

The issuer is YieldFi, governed by British Virgin Islands (BVI) law [S3][S6][S7]. No regulatory endorsement applies, and the tokens are characterized as high-risk instruments that are not deposits, not bank products, and are not protected by any investor compensation or deposit protection scheme [S7]. Tokenholders acquire no legal or beneficial ownership of underlying assets, only a subordinated contractual claim payable solely from Series Assets after the Series Waterfall [S1][S8][S3]. Access requires KYC, AML, and Greenlisting; U.S. persons, United Kingdom, China, and sanctioned-jurisdiction persons are excluded [S7][S9][S10]. No security interest is granted; protection relies on series-segregated, bankruptcy-remote structuring [S3][S6].

Vault tokens follow ERC-4626 on Ethereum Mainnet and ERC-20 on BNB Smart Chain [S2][S4][S11][S12]. Minting deposits mint tokens in one transaction, priced at the higher of current or end-of-epoch NAV; redemptions enter a queue, burn tokens, and pay the designated Settlement Currency targeting same-day to roughly T+2 [S4][S2]. NAV publishes via onchain PriceOracle contracts and a Chainlink adapter [S4][S11].

# Asset senders (monthly) methodology

## 1. Overview

Asset senders (monthly) is defined as the number of unique addresses from which asset transfers are initiated over a rolling 30-day period. For each tracked asset, outgoing transfer transactions are analyzed across supported blockchains to identify the sending addresses. These addresses are deduplicated over a 30-day window to represent the monthly active sender base. This metric is utilized to evaluate user adoption, transactional activity, and the overall utility of tokenized assets.

## 2. Data sources

- **EVM chain events**: Token transfer events, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: Token transfer instructions
- **Aptos, Sui, Cardano, and Stellar Classic data**: Token withdraw transactions
- **Stellar Soroban, Algorand, Near, Injective, and Ripple data**: Token transfer transactions
- **Polkadot Asset Hub events**: `Transferred` events from `assets` pallets
- **Asset metadata**: Token contract addresses and decimal precision

## 3. Step-by-step calculation

### Component A: Extract daily asset senders

- **Purpose**: Identify unique addresses initiating transfers on a daily basis
- **Logic**: On EVM-compatible chains, token transfer events are parsed to extract the sender address from the transaction, excluding the zero address. On Solana, token transfer instructions are parsed to identify the authority address. On Aptos, Sui, Cardano, and Stellar Classic, token withdraw transactions are parsed to extract the account address. On Stellar Soroban, Algorand, Near, and Injective, token transfer transactions are parsed to extract the sender address, excluding null addresses. On Ripple, token transfer transactions with negative values are parsed to identify the sending account address. On Polkadot Asset Hub, `Transferred` events from `assets` pallets are parsed to extract the sender address. For all chains, the extracted addresses are grouped by day and token address to produce a daily record of unique senders.
- **Key fields**: `timestamp` (block day), `token_address` (asset identifier), `sender_address` (initiating address)

### Component B: Aggregate rolling monthly senders

- **Purpose**: Calculate the unique sender count over a rolling 30-day window
- **Logic**: A daily datespine is generated to establish a continuous timeline. For each day in the timeline, a 30-day lookback window is constructed, encompassing the current day and the preceding 29 days. Daily sender addresses collected within this window are aggregated and deduplicated. The total number of unique, deduplicated addresses is then counted for each asset on each day.
- **Key fields**: `timestamp` (calculation day), `token_address` (asset identifier), `asset_senders` (unique monthly sender count)

### Component C: Final aggregation and zero-filling

- **Purpose**: Combine data across chains and fill missing activity days
- **Logic**: The deduplicated monthly sender counts are aggregated at both the individual chain level and the global asset level. For days where no transfer activity is recorded for a tracked asset, the metric is filled with zero values to maintain a continuous time series.
- **Key fields**: `timestamp` (reporting day), `chain_id` (blockchain identifier), `token_address` (asset identifier), `asset_senders` (final monthly unique sender count)

YieldFi

YieldFi vyUSD (vyUSD) is a token providing exposure to a tokenized fund issued by YieldFi through YieldFi.

Each token is a collateral-backed contractual exposure rather than a direct claim on the issuer and has paused, with redemption still open issuance.

The fund is open-ended, invests in crypto assets, keeps its assets in accounts segregated from the issuer's own funds, and charges a 2% annual management fee.

Retail investors and institutions can mint and redeem directly with YieldFi in USDC and USDT, and holders have a right to redeem at net asset value with two-to-five-business-day settlement.

Holder terms are governed by the law of the British Virgin Islands.

vyUSD has been issued on Ethereum as an ERC-4626 token since June 2025, with bridged versions on four more.
