One of the most common mistakes in discussions about stablecoins is focusing on the technology before understanding the problem that it is trying to solve.
For all the advances in technology over the past several decades, moving money across borders remains surprisingly inefficient. International payments often rely on multiple intermediaries, settlement can take several days, fees can be significant, transparency is limited, and access depends on banking infrastructure that was designed long before the internet became the foundation of global commerce (this was exactly how I discovered USDT myself ๐ ).
This issue is noticeable compared to how information moves today, almost instantly and globally with very little friction. Money, however, still largely depends on systems built around banks, correspondent banking relationships, business hours and jurisdictional boundaries.
Stablecoins emerged as an attempt to address this gap by combining the stability of traditional currencies with a digital infrastructure that allows value to move more efficiently. And they are not trying to replace existing currencies. The most successful stablecoins are denominated in the same currencies that already dominate the global financial system, primarily U.S. dollar and Euro. Their value is not in creating a new unit of account, but in creating a different way for that unit of account to move through the digital economy with low fees, global coverage and instant execution.
This distinction helps explain why stablecoins have succeeded where many other blockchain applications did not achieve meaningful adoption. Rather than asking users to accept an entirely new monetary system, stablecoins allow them to continue using familiar currencies while benefiting from a different settlement infrastructure.
Stablecoin transaction volumes have grown rapidly. According to Visa's on-chain analytics, stablecoins processed more than $24.4 trillion in transaction volume since 2019. The total stablecoin marketcap has also grown to more than $160 billion, while major issuers such as
@tether and
@circle now serve tens of millions of users globally. Business adoption continues to increase, and nearly every major financial institution, including J.P. Morgan, PayPal, Visa, Mastercard, etc, is now exploring or actively developing stablecoin-related initiatives.
Stablecoins are often discussed as a separate category within digital assets, while in reality they are the first successful example of tokenization at scale. For major ones, like USDT and USDC, every token represents a claim on an underlying asset held outside the blockchain. In other words, stablecoins demonstrated that tokenized representations of real-world assets could attract users, liquidity and global adoption.
But the whole tokenization ecosystem is much broader than stablecoins, as we will see in the next parts of this series.
