Sandwich Trades Table

The Sandwich Trades table captures DEX events where sandwich trading activity is detected. Sandwich trading involves placing two trades (a front-run and a back-run) around a victim’s trade to manipulate the market price for profit.

Sample Query

Finding the total USD amount of sandwich trades by project and date: 
select 
  date_trunc('week', block_timestamp) as date,
  project,
  sum(usd_amount) as sandwich_trade_volume_usd
from ethereum.dex.sandwich_trades
group by date, project

​
Methodology

We use the dex.trades table to construct this table. This table contains all trade events from DEX protocols. We identify sandwich trades using the following criteria:
  1. Trade Pair Identification:
    • The sandwich trade (swap1 , swap2) must occur within the same block.
    • It must be executed in the same liquidity pool (same liquidity_pool_address).
    • It must be executed by the same signer (transaction_from_address).
    • The transaction indices must be different (transaction_index).
  2. Direction Determination:
    • If s1.transaction_index > s2.transaction_index, the trade is a “back” part of the sandwich.
    • If s1.transaction_index < s2.transaction_index, the trade is a “front” part of the sandwich.
  3. Token Matching:
    • The token bought in the first trade (s1) must match the token sold in the second trade (s2).
    • Alternatively, the token sold in the first trade (s1) should be the token bought in the second trade (s2).
Exclusion of Non-Applicable Projects:
  • Exclude DEXs without the concept of liquidity pools, such as RFQ protocols like Airswap.
