Ethereum dominates USDC issuance with 70% of $72B market cap

If you want to understand where the stablecoin economy actually lives, look at Ethereum. Circle’s USDC has grown into a $72 billion asset, and roughly 70% of that supply, around $49.5 billion, is issued natively on Ethereum.

The numbers behind the dominance

Ethereum’s share of USDC issuance sits at approximately 68.8% of total supply. Solana, which is widely considered Ethereum’s most credible competitor for stablecoin activity, hosts around $7 billion in USDC. That is roughly one-seventh of what Ethereum handles.

USDC itself has grown considerably over the past year or so. The total supply has climbed from around $60 billion in early 2025 to over $72 billion today, driven by institutional adoption and the continued expansion of DeFi protocols that rely on dollar-denominated liquidity.

Circle first launched USDC on Ethereum in September 2018. The acceleration of multi-chain expansion came with the rollout of the Cross-Chain Transfer Protocol, or CCTP, starting in 2023.

What CCTP actually changes

Before CCTP, moving USDC between blockchains meant using a bridge, which meant holding a wrapped or “bridged” version of the token, often called USDC.e on chains like Avalanche. Bridged tokens carry smart contract risk, are not directly redeemable with Circle, and create a fragmented liquidity picture.

CCTP burns the tokens on the source chain and mints fresh, native USDC on the destination chain. The user ends up with a token that is directly backed by Circle’s reserves, not a derivative of one.

Circle has now extended native USDC and CCTP support to 35 blockchains. Recent additions in 2026 include Cronos, Injective, Stellar, and World Chain.

Stellar’s inclusion is worth noting specifically. Stellar has historically been oriented toward cross-border payments and remittances rather than DeFi. Native USDC on Stellar signals that Circle is pursuing the broader payments infrastructure market, not just DeFi activity.

Why Ethereum’s lead is stickier than it looks

Ethereum’s DeFi ecosystem has years of accumulated liquidity in lending protocols, decentralized exchanges, and yield strategies, all denominated in USDC. Moving a large institutional position through a thin liquidity environment creates slippage. Moving it through Ethereum’s ecosystem, at scale, does not.

For investors and traders watching stablecoin market structure, the $72 billion USDC supply figure is less interesting than where it sits. Ethereum’s $49.5 billion slice of that pie is the foundation for the lending rates, swap depths, and yield opportunities that define DeFi economics.

As native USDC reaches more chains through CCTP, the use case for Tether’s USDT, which still leads overall stablecoin supply, becomes more contestable on newer networks. Chains that once defaulted to USDT because native USDC was unavailable now have a choice.
