If there is one good thing about stablecoins, it is that their value always remains the same. This is why they are very attractive for sending value to any country, since both parties can have predictability about the equivalence of the amount they send and receive.
Each user can send their tokens to a valid address and thus transfer their stablecoins without further complications and without intermediaries.
For example, money can be sent or received between Argentina and the United States, originating and converted into pesos or dollars, using DAI, USDT or USDC. And this serves to facilitate international transactions for both natural persons and legal entities.
Any user can purchase a number of stablecoins with the fiat currency of their choice, and then transfer those stablecoins to an offshore account, where the recipient can exchange them back into fiat money.

Stablecoins allow value to be transferred to other countries in a simple way and without volatility problems.
ERC-20 transfers and tokens
Transactions of ERC-20-based stablecoins, such as DAI and USDC, have already become the largest value transfer vehicle on the Ethereum network, surpassing even ETH, the native token of that network.
The cost per transaction on Ethereum has increased significantly in recent years, as a result of the massiveness gained by its DeFi and NFT sectors. But various alternatives were appearing in blockchains whose operation allows them to lower the transaction cost, or layer 2 solutions to lower the cost of Ethereum.
All of this currently allows stablecoins pegged to the dollar to be present on various networks such as the Binance Smart Chain (which has BUSD) or Terra (TerraUSD).
