ParaSwap

About ParaSwap

ParaSwap is a DEX aggregator in the same mould as 1inch, splitting orders across venues to improve execution. Its airdrop is studied for how it was filtered rather than for what it paid.

Meeting the volume threshold was not sufficient. ParaSwap layered on behavioural criteria designed to catch wallets that traded like scripts rather than people, and excluded large numbers of addresses that technically qualified. Around 20,000 wallets survived to share 150M PSP.

The decision was contested loudly at the time and became a reference point for every team that has since had to decide how aggressively to prune a claim list.
