Ethereum Leads Stablecoin Supply As Chain Data Shows $153B On Mainnet

Ethereum holds about $153 billion in stablecoins, keeping mainnet as the largest blockchain for onchain dollar liquidity.

The latest stablecoin chain data places total tracked stablecoin supply near $311 billion, with Ethereum holding about $153 billion. That gives Ethereum the largest single-chain stablecoin base across public blockchains.

Ethereum’s position comes from deep USDT and USDC liquidity, DeFi settlement, institutional custody flows, tokenized-asset activity and large-value transfers. Mainnet fees remain higher than many competing networks, but Ethereum still carries the deepest pool of dollar-linked assets for DeFi and institutional settlement.

USDT And USDC Carry Mainnet Liquidity

USDT and USDC remain the main stablecoins on Ethereum, giving the chain its strongest settlement base.

Tether’s USDT holds the largest stablecoin share on Ethereum, while USDC remains central to regulated settlement, DeFi liquidity, payments and institutional access. The same dollar liquidity supports lending markets, decentralized exchanges, tokenized funds, OTC settlement and treasury management.

Bank-led stablecoin access is also expanding around USDC. Standard Chartered recently launched institutional USDC minting and redemption with Circle, giving eligible clients a route into USDC through a global bank-led structure.

Ethereum’s stablecoin base is also important for tokenized assets. Stablecoins act as the cash leg for tokenized treasuries, funds and public-market products, allowing issuers and traders to settle transactions without leaving blockchain rails.

Solana And L2s Expand Dollar Liquidity

Ethereum still leads by total stablecoin value, while Solana and Ethereum Layer 2 networks continue building their own dollar liquidity bases.

Solana now holds about $15 billion in stablecoins, with USDC carrying a major share of activity. Circle recently minted another 1 billion USDC on Solana, adding fresh liquidity to one of the busiest non-Ethereum stablecoin networks.

Arbitrum remains one of the largest Ethereum Layer 2 stablecoin hubs. The network recently crossed $7.8 billion in stablecoins while transfer volume stayed elevated across DeFi, trading and treasury activity.

The growth of Solana, Base, Arbitrum and other chains shows that stablecoin usage is spreading across cheaper settlement environments. Ethereum’s advantage remains the size of its liquidity base and its role as the main settlement layer for higher-value onchain finance.

Stablecoin Settlement Stays Concentrated

Stablecoin liquidity remains concentrated around a small group of networks, with Ethereum holding the largest single-chain amount.

Tron remains a major USDT transfer network, Solana is building deeper USDC liquidity, and Ethereum Layer 2s are absorbing lower-cost transfers and application activity. Even with that spread, Ethereum mainnet still anchors the largest stablecoin pool.

As of July 5, Ethereum held about $153 billion in stablecoins out of roughly $311 billion tracked across chains, leaving mainnet as the biggest onchain dollar settlement layer.
