Wu Shuo learned that, according to payment data scientist Alex, the blockchain payment index evaluated through P2P transfers, remittances, merchant payments, and fintech infrastructure, with Solana ranking first as the most balanced, though its main weakness is that the liquidity of stablecoins lags behind Ethereum and Tron; Polygon ranks second, excelling in cost, speed, and reliability, with the highest adoption rate, but its biggest issue is low stablecoin liquidity; Stellar ranks third, performing well in cross-border transfers and remittances, but has a relatively small stablecoin ecosystem, with a stablecoin supply of only $2 billion; Tron ranks fourth, dominating stablecoin trading volume, especially in large and cross-border flows, but small retail payments are limited by fee structures; Ethereum ranks fifth, holding 55% of the global stablecoin supply, but its payment user experience has underlying flaws, making it unsuitable for daily payments.
