Melania Trump's NFT was sold for $170,000 to....herself.

The address (aka address #1) that minted the NFT sent 473,657.64 USDC to an intermediary address (#2). The intermediary address swaps some of that USDC for 1,816.08 SOL. Then Address #2 sends 1800 SOL to a 3rd address.

The third address makes a bid and wins the NFT for 1800 SOL. That 1800 SOL goes to address #1 (the one that minted the NFT). Then address #1 sends the 1800 to the intermediary Address #2. The intermediary address swaps the 1800 SOL to USDC.

Blockchains, amirite?
