Not yet, but Polygon is closer to the throne than its supply numbers suggest. The chain ranks ninth by total stablecoin supply, yet it has quietly become the busiest settlement layer for $USDC transfers and is now funneling acquisitions, product launches, and a rumored $100 million funding round into one goal: owning real-world stablecoin payments.
The case is no longer speculative. Activity metrics, enterprise integrations, and a formalized payments stack all point to a chain that has stopped trying to be a general-purpose Ethereum scaler and started competing to become the rails for digital dollars.
Where does Polygon actually rank?
Polygon holds roughly $3.56 billion in stablecoin supply, up about 1.6% over the past 30 days. That puts it ninth among chains, well behind Ethereum’s $167 billion and Tron’s $87 billion. $USDC makes up close to half of that supply.
Where Polygon pulls ahead is in transfer activity. Data from Allium Labs, shared by on-chain analyst Peter the Rock on April 20, shows Polygon capturing 35.2% of all $USDC transactions across major chains, its ninth straight week in first place. On transfers specifically, Polygon handled 52.1% of $USDC movement, which is roughly three times Solana’s share. The chain also accounts for 32% of all USD-based stablecoin transfers, more than double second-place BNB Chain.
Lifetime volume has now crossed $2.4 trillion in stablecoin transfers, with non-USD activity contributing another $11.1 billion. Polygon hosts more than 30 local-currency stablecoins, including a heavy concentration of Latin American issuers such as BRLA, BBRL, and COPM. Japan’s yen-denominated JPYC has also leaned heavily on Polygon, with roughly $90 million of its $136 million in cumulative volume settling on the chain.
What is the Open Money Stack?
Polygon’s payments pitch centers on the Open Money Stack, or OMS, which it formally announced in January. The framework bundles on-chain settlement, smart wallets, fiat on and off-ramps, cross-chain routing through Trails and AggLayer, and compliance tooling into a single integration path for enterprises.
Two acquisitions totaling roughly $250 million fill in the gaps. Coinme brought 50,000 U.S. retail cash-access points and a stack of money-transmitter licenses. Sequence added non-custodial smart wallets with passkey login. Both pieces plug directly into the OMS pipeline.
Enterprise traction has followed. Revolut has crossed $1.2 billion in stablecoin volume on Polygon. Paxos has processed more than $1.3 billion. Stripe, Flutterwave, Mastercard, and Polymarket are all live integrations. The average $USDC transfer cost on the chain is $0.0008.
Is Polygon raising $100 million for stablecoins?
On April 8, The Information reported that Polygon Labs is in early-stage talks to raise up to $100 million through an equity sale earmarked for a new stablecoin payments business. The round has not closed, and the figure sits in a $50 million to $100 million range.
If it does close, the raise would formalize what the product roadmap already implies. Polygon is not issuing its own stablecoin. It is building the compliance, distribution, and settlement layer around existing issuers like Circle, Tether, and regional players. The funding would extend that push, particularly in regulated markets where banks and fintechs want a single counterparty to onboard.
What does sPOL add to the mix?
On April 14, Polygon launched $sPOL, a native liquid staking token for $POL. By April 20 it had attracted 144 million $POL, worth roughly $13 million, in total value locked. Holders earn staking rewards plus a share of priority fees while keeping their capital liquid.
sPOL does not touch stablecoins directly. It does improve capital efficiency on the chain, which matters for liquidity providers and market makers moving dollar-pegged assets across Polygon’s DeFi venues. FRAX’s fxUSD pools, for example, hit $1 million in TVL and a $1.2 million daily volume record shortly after launch, with cumulative volume near $6 million.
Can Polygon really take the throne?
Claiming the stablecoin crown from Tron and Ethereum requires more than activity share on $USDC. Tron still dominates retail $USDT flows across emerging markets. Ethereum still holds the majority of institutional stablecoin supply. Solana and Base are competing hard for payment-native issuers.
@0xPolygon‘s bet is that fees matter more than prestige. Sub-$0.001 transfers and under-five-second finality from the Heimdall v2 upgrade are difficult to match for payroll, remittances, and merchant settlement, which is where the next wave of stablecoin volume is most likely to land.
Global stablecoin transaction volume passed $33 trillion in 2025, and the U.S. GENIUS Act gives issuers a clearer regulatory path. If Polygon executes the OMS, secures funding, and retains its activity lead, the ninth-place supply ranking could look very different by year-end.
