Trades

The DEX trades table contains swaps made on decentralized exchanges, consolidated into a single table.

Project Coverage:

Currently, we support the following projects on Polygon.

curve_v1, curve_v2

Methodology

We adopted a protocol-based and event log-based approach to index swap events.

In brief, the swap events for each protocol are identified by the event signature (topic0), which contains the amount of tokens swapped and the address of the sender and receiver.

For protocols such as Uniswap v2 and v3 the token address swapped is identified by the liquidity pool creation event using the pool address. The amount of tokens traded is adjusted by the token's decimal value and then multiplied by hourly price oracle data to give the USD value of the transaction.

Sample Query

Finding the swap volume of indexed projects on Polygon in the last 7 days.

select 
  date(block_timestamp) as date,
  project, 
  sum(usd_amount) as usd_volume 
from polygon.dex.trades
  where current_date - date(block_timestamp) < 7
  group by date, project
  order by date desc

Table Columns

_str columns are numeric fields casted as varchar to retain precision when summing.

Column Name
Description
Example

project

The project (decentralized exchange) of the liquidity pool that the swap occurred from.

uniswap

protocol

Version of the protocol.

uniswap_v3

liquidity_pool_address

Contract address of the liquidity pool holding the asset. For protocols such as airswap, this will be null.

0x057932cec2f7aceeb3f8495baa42cb30570b790a

sender_address

The address of the sender emitted on the swap event logs. This can be a router or pool address, which is different from the transaction initatior transaction_from_address that initiated the swap.

0xe592427a0aece92de3edee1f18e0157c05861564

to_address

Address of the recipient emitted on the swap event logs. For example, we use the to_address from the uniswap v2 swap event log and the recipient_address from the uniswap v3 swap event log.
