Stablecoins like Tether (USDT) and USD Coin (USDC) aim to maintain a stable value, typically pegged to the U.S. dollar.
USDT (Tether)
Launched in 2014 by Tether Limited, USDT was one of the first stablecoins. Initially built on Bitcoin’s Omni Layer, it has expanded to multiple blockchains, including Ethereum, Tron, and Solana. USDT maintains its 1:1 USD peg through reserves, primarily cash, cash equivalents, and other assets, though its reserve transparency has faced scrutiny. Tether has grown to dominate the stablecoin market, with a circulating supply exceeding $150 billion as of 2025.
USDC (USD Coin)
Introduced in 2018 by Circle and Coinbase, USDC is a newer stablecoin emphasizing regulatory compliance. Built primarily on Ethereum, it also supports other blockchains like Solana. USDC is backed by fully audited reserves of cash and U.S. Treasury securities, with monthly attestations enhancing trust. Its circulating supply is around $60 billion as of 2025. USDC’s development prioritizes institutional use, partnerships with financial entities, and integration into regulated financial systems.
Market Overview
The combined market cap of USDT and USDC is around $210 billion, ranking them collectively near the 62nd largest company globally by market value. After a volatile period from mid-2022 to late 2023, both stablecoins have seen steady market cap growth since 2024, reflecting increased adoption and stability in the crypto market.
