Here's a heart-wrenching reality: You have several thousand U of stablecoins lying in your Wallet, but you're stuck because you're short 0.5 ETH for the Gas fee. Corporate finances are even worse; just managing the transaction fee Tokens across various chains requires creating an Excel spreadsheet.

It's quite ironic when you think about it carefully - we go through so much effort to create stablecoins to fight against inflation, yet every time we make a transfer, we still have to look at the fluctuations of the coins. It's like having a sufficient balance in your mobile Alipay, but you must first buy some game tokens to make a payment; that logic doesn't seem right, does it?

However, some projects have already started making cuts.

The gas mechanism for the off-chain coin recently introduced by Plasma has disrupted a set of rules that haven't changed in ten years. The core logic is simple and straightforward: transaction fees are directly deducted using stablecoin, on-chain coins? Not needed anymore. It may sound technically simple, but think about what this means —

Companies doing cross-border transfers can finally calculate costs in advance without having to monitor the market daily and worry about Gas surges. Ordinary people can carry only USDT in their wallets and move around freely, no longer needing to buy obscure coins just to experience a certain Dapp. This simplification of experience may be more critical than you think.

The timing is also very subtle. The daily trading volume of stablecoins has already surpassed 100 billion, and the testing progress of central bank digital currencies in various countries is also accelerating. When traditional finance starts to take stablecoins seriously, those public chains that still hold onto the logic of "must hold the native Token" may find themselves in increasingly awkward situations.

Visa has already been using stablecoins for settlement, and PayPal also supports digital currency transfers. If mainstream payment scenarios in the future are all direct routes with stablecoins, will those chains that require multiple exchanges and layers of fees become like public payphones that require coins to use – usable, but no one wants to use them?

This is how technological iteration works; it's not about who makes the loudest noise, but rather about who truly solves the problems users face every day. While everyone is talking about multi-chain, cross-chain, and Layer 2, the real breakthrough may be hidden in these "not-so-cool" underlying transformations.
