tl;dr

• Tether’s USDT on Polygon has been upgraded to native USDT0
• Transfers between USDT0 chains is seamless and easy, with Polygon leading the way in low fees 
• The upgrade also brings native XAUt0, the omnichain version of Tether Gold (XAUt), for wider multichain compatibility

The community asked. We shipped. 

Tether’s stablecoin on Polygon has been upgraded from USDT to Polygon-native USDT0, the omnichain deployment of USDT. Users don’t need to take any action. The upgrade simply provides lower fees and better liquidity. 

Before the migration, USDT was bridged via Polygon Proof-of-Stake as a child asset. Instead of a native token on Polygon, USDT pointed to an address on Polygon’s bridge.

By contrast, Polygon-native USDT0 is deployed directly on the network. This simplifies transactions and deepens liquidity in a growing stablecoin and payments ecosystem:

• lower fees on Polygon, with industry-low stablecoin fees; 
• deeper liquidity on Polygon, with more than $3 billion in stablecoin liquidity; and
• faster bridging to other chains supporting USDT0 via USDT0’s native bridge, for superior app experience and unified liquidity.

The USDT0 migration joins native USDC by Circle that picked up steam last year, better positioning Polygon as the premier destination for payments. 

Under the hood, the upgrade disabled the Polygon bridge contract address for USDT. Now, the Polygon Portal cleanly routes future flows to USDT0’s canonical bridge. Additionally, this step has shipped native XAUT0, the omnichain version of Tether Gold (XAUt), on Polygon, too, for a wider variety of native assets that bring deeper liquidity and more options.

Polygon’s recent upgrades on the road to going gigagas (100k transactions per second) bring new levels of speed and finality.

With ~5s settlement, 2s blocktimes, robust support for new levels of account abstraction, plus 1000 TPS with 5000 incoming—Polygon is purpose-built to support onchain payments and real-world assets at internet scale. 

Polygon leads in peer-to-peer micropayments (under $1K) across every chain, and ranks second in midsized payments ($1-10K). With stablecoin dominance picking up speed, native USDT0 continues the forward acceleration of a payments behemoth.

The USDT0 upgrade on Polygon prepares the system for Agglayer-integration and broader multichain asset support, later this year.   

Stay tuned and sail away: more shipping incoming.
