For the time being, for every DEX/AMM that is added onto DexGuru, we currently index and display transaction data only from the date/time they are implemented.
This means for all transactions (and its TX data) that have occurred before the date of the DEX/AMM implementation date, will not be included in transaction lists, aggregates/counts and charts that involve the pre-implementation time period.
💡 We are working on indexing and back-syncing all historical transactions and transaction data for every DEX/AMM that is supported on DexGuru. The current ETA for completion is by Q1 2022.
For the time being, a complete list of DEXs dates and their added date are available for your reference at Supported DEXs/AMMs.
