$USDC The smallest purchase for $USDC occurred in 2023 on the OpenSea platform, when a user acquired a digital sticker in the form of an emoji for 0.01 USDC. This was approximately $0.01, as USDC is pegged to the dollar. The purchase became part of an experiment to test microtransactions in NFT marketplaces. Interestingly, the gas fees on the Ethereum network amounted to $2, which was 200 times the cost of the sticker! User @NFTMicroBuyer posted on X: "I bought an emoji, but I paid for gas like it was dinner." This case highlighted how high fees can make microtransactions with USDC absurdly expensive, despite the stability of the stablecoin. Since then, OpenSea has implemented solutions to reduce fees.
