Users instruct the Bankr agent in chat. Bankr executes swaps on existing DEXs and launches new tokens via Whetstone's Doppler launchpad on canonical Uniswap V4. Launched tokens carry a 0.7% swap fee (95% to the token creator, 5% to Doppler). Bankr also operates paid Bankr Club subscriptions ($20/mo).

On Robinhood Chain, Bankr is the dominant token launcher: 10,936 tokens launched in the first two weeks via its Doppler launch hook, each paired against WETH on Uniswap V4.

Bankr (bankr.bot) is an AI trading agent on Farcaster, X, and web that lets users buy, sell, and launch tokens through natural-language chat, executing on-chain via account-abstraction wallets.

# Bankr Fees Methodology

## 1. Overview

Fees measures the total value paid by users to use Bankr. Economic value is generated from swaps routed through Uniswap V4 pools that utilize the Bankr Doppler hook. A flat fee of 0.7% is levied on the Wrapped Ether (WETH) leg of each swap, representing the primary mechanism of protocol fee generation.

## 2. Data sources

- **Blockchain events**: `Initialize` and `Swap` events from `PoolManager` contracts, covering Robinhood Chain
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Doppler-hook pool identification and WETH position mapping

- **Purpose**: Identification of eligible Uniswap V4 pools utilizing the Bankr hook and determination of the position of the WETH asset.
- **Logic**: `Initialize` events from `PoolManager` contracts are parsed to filter for pools where the hook address matches the Bankr hook and either of the pool assets is WETH. The position of WETH (either asset 0 or asset 1) is mapped for each pool ID to ensure the correct asset leg is targeted for fee calculation.
- **Key fields**: `id` (pool identifier), `currency0`, `currency1`, `hooks`

### Component B: Doppler-hook swap volume extraction

- **Purpose**: Extraction of raw WETH swap volume from eligible pools.
- **Logic**: `Swap` events from `PoolManager` contracts are joined with the identified Bankr pools. Based on the mapped WETH position, the absolute raw value of either `amount0` or `amount1` is extracted to represent the WETH notional volume.
- **Key fields**: `id` (pool identifier), `amount0`, `amount1`, `block_timestamp`

### Component C: Fee calculation and USD conversion

- **Purpose**: Application of the protocol fee rate and normalization of the resulting values to USD.
- **Logic**: A flat fee rate of 0.7% is applied to the aggregated raw WETH swap volume. Raw fee amounts are normalized by decimal precision using asset metadata and converted to USD using end-of-day price feeds. Daily granularity is established using UTC day boundaries.
- **Key fields**: `fee_amount`, `timestamp`, `token_address`
