You have already listed the two most famous stablecoins on ERC20 - USDT & USDC. With the crazy ERC20 gas fee, I would like to suggest listing USDT & USDC on SOLANA.
Impacts: Top stablecoins in the world, the problem is that the gas fee on Ethereum is getting really expensive… an alternative would be to list these two coins on SOLANA to reduce significantly the transaction fee.
Benefits: More traders will be able to trade USDT and USDC without paying crazy transactions fees, they will also be able to buy or sell lower amount of USDT or USDC.
Risk: I don’t see any risk. Also, you already have integrated SOL, so it shouldn’t be that hard to integrate both tokens compared to other proposals.!
