I’ve been using STON.fi on $TON for a while now, and the cross-chain option that lets you move USDT from TON to Base in one flow has become one of the features I actually use.
Instead of hunting for a separate bridge, you stay inside the STON.fi app. You connect a TON wallet and a Base-compatible wallet, select USDT on TON, choose Base as the destination, enter the amount, review the rate and fees, and confirm. Most swaps finish in roughly 10–30 seconds. The assets remain native on each side because the process uses Omniston’s HTLC-based settlement — either both sides complete or both refund.
The official walkthroughs are clear:

A good primer on what a DEX is (and how STON.fi fits) is at https://whatisdex.com/.
Before you confirm any cross-chain swap, check the network, the exact token, the amount, and the receiving address. These transactions cannot be reversed. Starting with a small test amount is the simplest way to get comfortable with the flow.
If you want a quick way to practice spotting common crypto scams, the short interactive game at https://stonverse.com/cybersecgame/ covers the basics.
Have you moved stablecoins between TON and an EVM network before? What did you check first?
