sTEM, issued by Stablestocks Lab Limited, is a tokenized stock that gives onchain exposure to Tempus AI, Inc. Class A, a U.S.-listed instrument, with each token backed 1:1 by one underlying share held in custody with licensed brokers. [S1][S2]

sTEM tracks the live market price of Tempus AI, Inc. Class A (TEM), and if the underlying issues a dividend or distribution and eligibility requirements are met, those economic rights pass through to the tokenholder, though voting rights remain with custodian holders. [S1][S2] Tokenholders may stake into StableVault to receive yield-bearing stStocks combining dividends with DeFi yields. [S3] A Service Fee of 0.1% of the transaction amount applies, alongside upstream broker and trading fees. [S4]

Stablestocks Lab Limited, brand StableStock, is incorporated in the British Virgin Islands and operates from Singapore. [S2][S5] It does not hold financial-services licenses and disclaims being a regulated entity, relying on broker-dealer partners holding an AFSL, a Hong Kong SFC Type 1 license, and U.S. MSB registration. [S5][S2][S6] An sToken is the tokenized representation of a real share; tokens are unregistered under the U.S. Securities Act and offered only to Qualified Investors through affiliated entities. [S5][S1] U.S. persons are barred and KYC and AML verification applies for leverage and IPO access. [S5][S4] Tokenholders may redeem and burn tokens at any time to retrieve the underlying share. [S1][S2]

sTokens are issued natively onchain on Bsc through a liquidity partnership with Native. [S1][S7] Tokens are minted when brokerage-held shares are deposited 1:1 and burned on redemption, with mint, burn, buy, and sell records recorded permanently onchain. [S1][S8] Stablecoin settlement in USDT and USDC funds purchases of real securities, and reserve coverage is published per asset and verified by weekly assurance reports. [S9][S8]

# 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)

Tokenized stocks

StableStock earns revenue from transaction fees on sStock issuance and redemption via its StableBroker product, and from the spread between deposit/withdrawal flows. Distribution is direct-to-retail (StableBroker app) and B2B via wallet/exchange integrations on BNB Chain.

StableStock issues sStock tokens — ERC-20 tokens on BNB Chain backed 1:1 by the underlying U.S. equity or ETF held at a licensed custodian. The product catalog spans 500+ tokenized stocks and ETFs (e.g. sAAPL, sNVDA, sTSLA, sQQQ) including newly-IPO'd names like sCRCL (Circle) and sBLSH (Bullish) and leveraged/inverse exposures. All sStocks are deployed as BeaconProxy contracts from a single upgradeable factory.

StableStock is an onchain stock asset platform that lets users buy and trade U.S. stocks and ETFs using stablecoins. StableStock is the issuer of sStock tokens — tokenized representations of equities — and is backed by YZi Labs (formerly Binance Labs) among others.
