The goal of this task to find pairs of tokens (sender → receiver) that are regularly transfer USDC funds. We are interested in pattern that would look like a subscription/automated transfers.

To find such sender-receiver pairs:

1. Consider only successful USDC transfer transactions with at least 1 USDC transferred.
2. Only find pairs that had a transfer each day from 18 of May (including) to 18 June 2025 (not including)
3. There should be exactly one transfer per day (if we consider only USDC transfers of the same direction)

Solana data:

I would recommend using Dune’s tokens_solana.transfers link, but you can use any data source.
