Points of Focus

• USDC remains Solana’s largest stablecoin, but its share has fallen below 50% as the network’s stablecoin market becomes more diverse.
• USDT’s supply on Solana increased 34% during the first quarter, while newer assets such as USD1, USDGO, and yield-bearing stablecoins expanded.
• The shift could reduce Solana’s dependence on Circle while fragmenting liquidity across more settlement and yield products.

Long-held lead of Circle’s USDC (USDC) on Solana is eroding as USDT and other dollar-pegged tokens capture a larger share of the network’s liquidity.

As of July 21, Solana hosted roughly $15.15 billion in stablecoins, per DefiLlama. USDC made up about $7.08 billion of that total, equating to a 46.76% share. This is short of the majority stake it once commanded on the chain.

Tether’s USDt (USDT) sat in second place with around $2.91 billion on Solana. Its circulating supply rose almost 17% in the prior seven days, though it was still a bit lower on a 30-day basis.

The pattern goes well beyond the rivalry between USDC and USDT. World Liberty Financial’s USD1 held over $1 billion on Solana, and USDGO likewise surpassed the $1 billion threshold. PayPal’s PYUSD, Global Dollar’s USDG, and assorted yield-bearing products each accounted for hundreds of millions of dollars.

Solana’s stablecoin market is growing less concentrated

The drop in USDC’s share does not automatically signal that demand for Circle’s token is falling apart. Its supply on Solana remained above $7 billion and was still more than double that of USDT.

Rather, the numbers highlight a fast-growing stablecoin landscape in which newer issuers are expanding more quickly than the established leader.

According to Galaxy Research, Solana’s overall stablecoin supply climbed 2.7% to $15.45 billion in the first quarter of 2026. In that same window, USDT supply grew 34%, while USD1 surged 473% to finish the quarter as the network’s third-largest stablecoin.

Stablecoins other than USDC and USDT have also made major inroads. These alternatives comprised 20% of Solana’s stablecoin supply, compared with just 4% at the start of 2025.

This growth encompasses traditional payment stablecoins, tokens built for decentralized finance (DeFi), and tokenized cash instruments that distribute yield to holders.

BlackRock’s BUIDL and Figure’s YLDS, for instance, expanded from nearly zero supply to approximately $900 million combined in the first quarter, according to Galaxy.

Competition may reshape Solana’s liquidity

A broader range of stablecoins could reduce Solana’s reliance on any single issuer and enable a wider array of use cases spanning payments, trading, lending, and tokenized real-world assets (RWAs).

At the same time, the change risks fragmenting liquidity. Decentralized exchanges and lending protocols may have to accommodate more trading pairs and collateral options instead of focusing activity primarily on USDC.

USDC thus stays a core part of Solana’s financial infrastructure, but it is no longer the network’s near-automatic digital dollar. The evolving market is increasingly split among Tether, payment companies, institutional asset managers, and crypto-native issuers, all vying for the same onchain liquidity.

How could it reshape Solana’s DeFi ecosystem?

The changing mix of stablecoins could significantly reshape Solana’s DeFi ecosystem. Lending protocols, decentralized exchanges, and derivatives platforms have historically relied on USDC as their primary source of liquidity and collateral. As USDT, USD1, USDGO, and other stablecoins gain traction, DeFi applications may expand support for multiple assets.

This will allow users to choose stablecoins based on liquidity, issuer preference, regulatory considerations, or yield opportunities. This diversification could reduce dependence on a single issuer while making the ecosystem more resilient to disruptions affecting any one stablecoin.
