Which Blockchains are Winning the Stablecoin Race?

Ethereum and Tron hold roughly $247.6 billion of the $316.137 billion of all stablecoins in circulation, more than three-quarters of the entire market. Add Solana and BNB Chain and the top four account for about 87 percent of the supply. The race for first place is settled. The fight worth watching is underneath, where XRPL just posted a 22.85 percent jump in a single week.

The Big Four Are Pulling Away

Ethereum (@ethereum) sits on top with $157.531 billion, or 49.83 percent of all stablecoin supply on a single chain. $USDT leads there at 50.88 percent, with $USDC close behind, so no single issuer controls it.

Tron (@trondao) is the most concentrated chain in the top tier. It holds $90.102 billion, and 97.92 percent of that is USDT. In practice, Tron is a USDT settlement rail. People move Tether on it because fees are low and transfers are fast, and that one use case has made it the second-largest stablecoin chain in crypto.

Solana ($15.301 billion) and BNB Chain ($13.329 billion) round out the group. Solana (@solana) leans USDC at 51.10 percent and added 4.35 percent on the week. BNB Chain (@BNBCHAIN) runs mostly USDT at 68.85 percent and barely moved.

Who Is Climbing Fastest?

The chasing pack is far smaller, but several chains are growing at rates the leaders cannot match. The two biggest names just behind the top five are Base ($4.83 billion) and Arbitrum ($3.837 billion), both Ethereum L2s leaning heavily on USDC. The faster movers sit below them. 

• XRPL: up 22.85 percent to $762.12 million. $RLUSD makes up 99.03 percent of that, so almost every stablecoin dollar on the XRP Ledger is Ripple's own coin.
• Stellar: up 8.72 percent to $804.2 million, edging ahead of XRPL by total supply. Its lead stablecoin is the yield-bearing USDY at 65.08 percent.
• Gnosis: up 7.15 percent to $503.77 million.
• Sui: up 6.40 percent to $490.18 million.
• Plasma: up 6.25 percent to $966.06 million.
• Aptos: up 5.50 percent to $1.924 billion.

Polygon holds a solid eighth place at $3.59 billion, but it actually slipped 3.56 percent on the week. So the current momentum story belongs to XRPL and Stellar.

What the Dominant Stablecoin Reveals

The "dominant stablecoin" column is a useful tell on the dashboard. It explains what is actually driving each chain's supply.

Three chains are effectively single-issuer rails, each above 95 percent concentration: Tron (USDT), XRPL (RLUSD) and Hyperliquid L1 (USDC). Hyperliquid already holds $6.498 billion, good for fifth overall.

Others run on a USDT-USDC mix. Ethereum, Solana, and Polygon are close to an even split, while Arbitrum and Sui lean toward USDC. That balance usually points to deeper DeFi activity rather than one dominant payment flow.

Avalanche's top stablecoin is $BUIDL at 32.37 percent, BlackRock's tokenized money market fund, a sign of where institutional cash is parking. Gnosis leans on $BRZ, a Brazilian real stablecoin, at 92.03 percent.

The Takeaway

The total stablecoin market is $316.137 billion, down $3.724 billion, or 1.16 percent, over the past week. The pullback was broad, which makes the green numbers stand out more. Ethereum dominance holding near 50 percent shows how concentrated the top of the market still is.

The league table is split into two: The big four are locked in and hard to displace. Below the top four, everything is a live contest, and the chains reading green this week are the ones gaining ground.
