Liquidity providers deposit funds into Buffer Finance and receive trading fees from binary options traders (supply-side fees).

Buffer Finance is a non-custodial binary options exchange built on Arbitrum and Polygon. Buffer Finance was founded by an anonymous team and launched in 2021.

BFR token holders own and govern the protocol. They currently take a cut of the total trading fees paid by binary options traders (revenue).

# Buffer Finance Treasury Methodology

## 1. Overview

The Buffer Finance treasury metric measures the total USD value of all tokens held in Buffer Finance's treasury wallet on Arbitrum. This metric provides insight into the protocol's financial reserves and asset diversification. The calculation tracks balance changes for a specific treasury address over time, converts all token holdings to USD using daily price feeds, and aggregates the total value.

## 2. Data sources

- **Arbitrum blockchain events**: Parsed `Transfer` events and other token movement events on the Arbitrum network to track token flows into and out of the treasury address
- **Arbitrum transaction traces**: Internal transaction data and contract interactions that may affect token balances
- **Token metadata**: Token contract information including symbols and decimal precision for proper balance calculations
- **End-of-day price feeds**: Daily token price data for USD conversion of all held tokens

## 3. Step-by-step calculation

### Component A: Balance change tracking
- **Purpose**: Tracks all token balance changes for the Buffer Finance treasury address
- **Logic**: Monitors the specific treasury address `0x691fa1d4dc25f39a22dc45ca98080cf21ca7ec64` on Arbitrum for all incoming and outgoing token transfers. The system processes blockchain events and transaction traces to identify when tokens enter or leave the treasury wallet. Each balance change is recorded with timestamp, token address, and net change amount. The calculation handles various token types and properly accounts for token decimal precision.
- **Key fields**: `timestamp` for when the balance change occurred, `account_address` for the treasury wallet, `token_address` identifying the specific token, `balance` representing the net change amount, and `token_symbol` for identification

### Component B: Cumulative balance calculation  
- **Purpose**: Converts balance changes into running total balances for each token
- **Logic**: Takes the stream of balance changes and applies cumulative sum calculations partitioned by timestamp grain, chain, treasury address, and token address. This creates a complete time series showing the total balance of each token held by the treasury at any given point in time. The calculation uses window functions to maintain running totals while preserving the chronological order of balance changes.
- **Key fields**: `balance` field is transformed from incremental changes to cumulative totals using sum over ordered windows

### Component C: Data continuity and forward-filling
- **Purpose**: Ensures continuous time series data by filling gaps where no balance changes occurred
- **Logic**: Applies forward-fill logic to extend the last known balance for each token across time periods where no transactions occurred. This creates a complete daily time series for all tokens, ensuring that periods of inactivity don't appear as zero balances. The forward-fill process maintains separate continuity for each combination of treasury address and token.
- **Key fields**: All dimension fields (`timestamp_grain`, `chain_id`, `account_address`, `token_address`) are preserved while the `balance` values are propagated forward through time gaps

### Component D: USD conversion
- **Purpose**: Converts all token balances to USD values using daily price feeds
- **Logic**: Joins the forward-filled token balances with end-of-day price data, matching on timestamp, chain, and token address. Each token balance is multiplied by its corresponding daily USD price to determine the dollar value of that holding. Only positive balances are included in the conversion, and the calculation uses safe multiplication to handle potential null or invalid price data. The conversion uses daily price granularity to ensure consistent valuation timing.
- **Key fields**: `amount` field contains the USD value calculated by multiplying `balance` with daily `price_usd` from the price feeds

### Final aggregation
- **Combining components**: All USD-converted token values for the treasury address are summed together to produce the total treasury value for each day
- **Currency conversion**: Token amounts are converted to USD using end-of-day price feeds, with safe multiplication handling to manage missing or invalid price data
- **Time aggregation**: Daily aggregation boundaries are used, with forward-filling ensuring complete time series continuity
- **Final calculation**: The total treasury value equals the sum of all individual token holdings (token balance × daily USD price) for all tokens held by the Buffer Finance treasury address, with treasury-specific formatting applied including zero-filling for periods with no data and chain availability filtering
