The previous payment king Celo, the largest stablecoin platform Mento, seems to be leaving, positioning itself as an on-chain foreign exchange platform. First, through the cross-chain protocol Wormhole, it plans to expand 15 issued USD, EUR, and JPY stablecoins to Solana, Base, and other chains. It then provides DEX and liquidity to make different forex tokens tradable. It should be noted that at present, the US dollar and euro have a certain liquidity and depth, and most of the others are only suitable for small exchanges, mainly because for security reasons, a 200% collateral ratio is required to mint the corresponding fiat currency tokens, which reduces some arbitrage opportunities. Although Mento's idea is very good, it still needs to be tested by the market, and the current deposit and withdrawal channels for Mento cooperation are mainly US dollars and the euro area, and the real hard demand should be Asia. I have a hunch that driven by the tide of stocks, U.S. bonds, and foreign exchange chains this year, there should be more and more such projects. Old payment and stablecoin projects may also accelerate their transformation here.
