TL;DR: Polygon Open Money Stack now supports TRON, giving payment and fintech businesses a single infrastructure layer for bank transfers, wallets, cross-chain routing and payouts involving TRC-20 USDT. Polygon says more than $94 billion of USDT currently circulates on TRON.
Polygon has spent much of 2026 trying to turn its Open Money Stack into infrastructure for moving real money rather than just crypto between wallets.
Its latest integration goes straight to one of the largest pools of stablecoin liquidity in the world.
Polygon Labs announced Thursday that Open Money Stack now supports TRON, allowing businesses to accept, hold, route and pay out USDT on the network while connecting those flows to fiat banking rails and other blockchains.
The attraction is obvious.
Polygon says TRON carries more than $94 billion in circulating USDT, representing more than half of the stablecoin’s supply across supported chains.
That liquidity is already heavily used in remittances, exchange transfers and dollar-based payments in markets where access to traditional banking can be expensive or slow.
Open Money Stack is designed to sit around that activity.
A business can give a customer a persistent TRON deposit address, accept USDT, hold the balance through an appropriate wallet model, route assets to other chains when required and eventually pay money out to a bank account, card, cash pickup location or another wallet.
The important part is that the customer does not necessarily have to see any of the cross-chain plumbing.
Polygon Trails can route assets between TRON and EVM networks so, for example, one side of a transaction can begin with USDT on TRON and the other can settle in a different supported stablecoin elsewhere.
That is very different from asking the user to find a bridge and move the funds themselves.
The integration also says something about Polygon’s strategy.
Rather than insisting that payment activity must happen on Polygon’s own chain, Open Money Stack is increasingly being presented as an orchestration layer that can work around whichever network customers already use.
TRON is a particularly strong test of that approach because many users are not choosing it for ideological reasons. They use it because USDT liquidity and payment habits already exist there.
For a remittance business, forcing those customers to migrate to another blockchain would add friction for little benefit.
Polygon’s answer is to let TRON remain the balance layer while its own software handles the surrounding services.
That could make the Open Money Stack business more valuable even when the end user never knows Polygon is involved.
Stablecoin competition is therefore moving beyond which network has the most supply.
The next battle is over the infrastructure connecting those balances to bank accounts, businesses and other chains.
TRON already has the dollars.
Polygon now wants to provide more of the machinery around them.
