Tether’s omnichain stablecoin protocol has quietly become one of the most heavily used pieces of infrastructure in crypto. Monthly USDT0 transfer counts climbed 438.2% over three years, with Polygon and Arbitrum One responsible for a combined 78.8% of all transfers.
The numbers behind the migration
Polygon’s stablecoin activity in 2025 has been staggering. The network processed 452 million stablecoin transactions and 1.4 billion transfers, representing year-over-year growth of 140% and 227%, respectively. Its stablecoin supply reached $2.83B, making it one of the most liquid Layer-2 environments for dollar-denominated tokens.
Arbitrum’s trajectory looks equally aggressive. Daily stablecoin transfers on the network went from roughly 80,000 per day in early 2023 to over 2 million daily by late 2025. That’s a 25x increase in less than three years. Daily transaction volumes now exceed $5B.
USDT0 itself crossed $100B in cumulative cross-chain transfer volume within just 525 days of its early 2025 launch. The protocol has attracted approximately 6.5 million active wallets.
Why Layer-2 networks are winning stablecoin flows
Sending USDT on Ethereum mainnet can cost anywhere from a few dollars to tens of dollars during congested periods. On Polygon or Arbitrum, the same transfer costs a tiny fraction of that.
USDT0 leverages LayerZero’s cross-chain messaging infrastructure to enable seamless transfers between networks, allowing native transfers across supported chains with a single transaction rather than manual bridging.
Both Polygon and Arbitrum have also attracted integrations from traditional finance players. Revolut and Stripe have built payment capabilities on Polygon, providing on-ramps that funnel real-world payment demand directly onto the network.
What this means for the stablecoin landscape
The competitive dynamics among Layer-2 networks themselves are also worth watching. Polygon and Arbitrum currently dominate with their combined 78.8% share, but newer networks like Base, Optimism, and emerging zero-knowledge rollups are all competing for stablecoin flows.
