Polygon plugs into Tron's $94 billion of USDT, and Tether signs a tenge stablecoin study with Kazakhstan
Two stablecoin announcements on October 7: a payments link to the biggest pool of USDT, and a non-binding agreement with a central bank. Neither is a launch yet.
Polygon Labs said on October 7 that it is extending its Open Money Stack to the Tron network, so that businesses can move USDT between Tron and Ethereum-style networks through one integration instead of stitching together a wallet provider, a bridge and a fiat on-ramp. The same day, Tether signed a memorandum of understanding with the National Bank of Kazakhstan and the Alatau City Authority to study stablecoins and asset tokenization. Both are about plumbing, and both are early.
What Polygon announced
According to CoinDesk, about $94 billion of USDT circulates on Tron, which is more than half of Tether's total supply and the largest single pool of stablecoin liquidity. Polygon's pitch is aimed at remittance firms, fintechs and payment providers: take a bank transfer, debit card payment or cash, convert it to USDT on Tron, move it where it needs to go and cash out to a bank account, all through one connection. Polygon co-founder Sandeep Nailwal said the integration gives businesses "a way to offer that service through one integration."
One caveat matters for anyone building on this. The integration does not remove licensing duties for payment companies. Polygon says its fiat-ramp service holds money-transmitter licenses covering 48 U.S. states, and Open Money Stack itself only launched in January 2026 after Polygon bought Coinme and Sequence. This is a product announcement, not evidence yet of volume.
Tether and Kazakhstan
The memorandum covers a study of how other countries issue stablecoins, a concept and pilot proposal for a stablecoin pegged to the Kazakh tenge, a framework for tokenizing real-world assets using Tether's Hadron platform, and training workshops for central bank staff. Pilots would run inside Alatau, a city set up with a special legal regime to encourage financial technology.
The wording is careful. An MoU is an agreement to explore, not a decision to issue anything, and the National Bank's deputy governor Binur Zhalenov was quoted stressing financial stability, transaction transparency and investor protection. A tenge stablecoin would be a different product from USDT: it would be a local-currency token, not the dollar token that dominates the market.
A third item: GSR's $100 million
Also on October 7, market maker GSR said it is committing $100 million, mostly as a credit facility, to a new on-chain vault business called Hare, built with the liquidity platform Turtle. CoinDesk reports the first products are Aave-powered vaults that earn yield on dollar stablecoins and on Paxos' tokenized gold. GSR supplies the starting liquidity before outside investors arrive. Yield on a vault comes from lending and liquidity activity, so it carries credit and smart-contract risk that a bank deposit does not.
What to watch
For readers following stablecoin rules, the useful signal is that dollar-token payments are being built for ordinary businesses faster than the rules around them. Our earlier coverage of the Fed's stablecoin capital rules and of Open USD's launch covers that side. The next checkpoints here are whether Polygon discloses real transfer volume through Tron, and whether Kazakhstan's pilot proposal is published.
