USDv, issued by the Solomon Protocol smart contracts under the governance of SOLO tokenholders, is a U.S. dollar-pegged stablecoin that maintains a 1:1 peg backed by crypto assets and derivatives held in off-exchange custody [S1][S2].

USDv targets a peg of 1.00 U.S. dollars (USD), with reserves generating return from a delta-neutral basis trade holding spot-long and perpetual-short positions in major tokens such as BTC, SOL, and ETH on centralized exchanges to capture funding and basis rates [S1][S3]. Holders pay a 0.2% minting fee [S2][S3]. Yield accrues to the staked sUSDv token, whose exchange rate appreciates rather than rebasing, or streams to permissioned holders via Yield-as-a-Service at a 0.25% to 1% annual fee [S1][S2].

USDv is not issued by a single corporate entity; it is governed through MetaDAO futarchy via the SOLO token, with administrative control of protocol reserves held in a 3-of-5 Squads multisig [S4][S5]. The economic claim is proportional exposure to underlying reserve assets plus accrued yield [S1][S2]. Minting and redeeming are restricted to approved, whitelisted entities, while sUSDv staking is permissionless and Yield-as-a-Service participation requires KYC and AML onboarding [S2][S6]. Whitelisted users redeem instantly at 1.00 USD from a minting-contract reserve buffer; ordinary users exit via Solana stablecoin pools [S6]. Reserve assets are secured with Ceffu through joint-control off-exchange custody [S3][S7].

USDv is an SPL token issued exclusively on Solana [S2]. Approved users deposit USDC, USDT, or SOL and receive USDv net of the 0.2% fee, triggering the delta-neutral hedge; the peg holds through two-way arbitrage [S2][S6]. Pricing references Pyth oracles, and monthly Ceffu custody attestations are published, with reports through April 1, 2026 [S8][S9].

# Asset senders (weekly) methodology

## 1. Overview

`Asset senders (weekly)` is defined as the number of unique addresses that initiate asset transfers over a rolling 7-day period. For each tracked asset, outgoing transactions are analyzed to identify the addresses responsible for moving tokens. This metric is utilized as a key indicator of weekly user activity and transactional engagement for tokenized assets across various blockchain networks. By aggregating unique sending addresses within a moving 7-day window, short-term fluctuations are smoothed out to provide a clearer view of active adoption.

## 2. Data sources

- **EVM chain events**: ERC-20 token transfers, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: Token transfer instructions
- **Other blockchain data**: Token transfer and withdrawal events from Aptos, Near, Polkadot Asset Hub, Stellar, Sui, Ripple, and others
- **Asset metadata**: Token contract addresses and asset mapping datasets

## 3. Step-by-step calculation

### Component A: Extraction of daily sending addresses

- **Purpose**: Identify and extract unique addresses initiating token transfers on a daily basis for each asset.
- **Logic**: On EVM-compatible chains, sending addresses are extracted from ERC-20 token transfers where the sender address is not the null address. On Solana, sending addresses are identified from token transfer instructions using the authority address. On Aptos, Sui, Cardano, and Stellar Classic, sending addresses are retrieved from token withdrawal events. On Stellar Soroban, transfers are parsed from Soroban token transfer events, excluding mint transactions where the sender address is null. On Polkadot Asset Hub, `Transferred` events from the `assets` pallet are parsed to identify the sender. On Ripple, outgoing transfers are identified where the transaction value is negative. On Near and Injective, sending addresses are extracted from token transfer events where the sender address is populated.
- **Key fields**: `timestamp` (block time truncated to the day), `token_address` (the contract or asset identifier), `sender_address` (the address initiating the transfer)

### Component B: Rolling 7-day window aggregation

- **Purpose**: Aggregate daily active senders into a rolling 7-day window to calculate weekly activity.
- **Logic**: A daily datespine is generated to establish a continuous timeline. For each day in the timeline, a rolling 7-day window is constructed by looking back at the preceding six days. Daily unique sending addresses are mapped to each active window based on their transaction timestamps.
- **Key fields**: `timestamp` (the reference day for the rolling window), `token_address` (the asset identifier), `sender_address` (the address active within the window)

### Component C: Final deduplication and aggregation

- **Purpose**: Calculate the final weekly unique sender count per asset and chain.
- **Logic**: Within each rolling 7-day window, sending addresses are deduplicated to ensure each unique address is counted only once per asset, regardless of transaction frequency. The deduplicated counts are aggregated at both the individual chain level and the global asset level. Missing dates are filled with zero values to maintain a continuous time series.
- **Key fields**: `timestamp` (the reference day), `chain_id` (the blockchain identifier), `token_address` (the asset contract address), `asset_senders_weekly` (the count of unique weekly sending addresses)

Stablecoin issuers

Solomon Labs

Solomon USDv (USDv) is a U.S. dollar stablecoin issued by Solomon Labs.

Each token tracks one U.S. dollar and is a collateral-backed contractual exposure rather than a direct claim on the issuer.

Custody of the reserves rests with Ceffu, and Ceffu attests them monthly.

Institutions can mint and redeem directly with Solomon Labs after completing KYC.

USDv has been issued on Solana as a SPL Token and SPL Token-2022 token since December 2024.
