Stablecoin transactions have witnessed a significant surge over the past year, with the Solana and Base networks emerging as prominent platforms for these digital assets. Solana accounted for approximately $1.8 trillion in new stablecoin volume, while Base facilitated around $1.5 trillion, underscoring their growing influence in the cryptocurrency ecosystem.
The overall stablecoin market experienced remarkable growth, with total transfer volumes reaching $27.6 trillion in 2024. This figure surpasses the combined transaction volumes of traditional payment giants Visa and Mastercard by 7.68%. The expansion reflects a broader shift towards digital financial systems, as users and institutions increasingly adopt stablecoins for various transactions.
A significant portion of this activity is attributed to automated trading bots. In 2024, bot-related transactions constituted approximately 70% of the total stablecoin transfer volume. On networks like Solana and Base, this figure was even higher, with bots accounting for 98% of the volume. These bots engage in high-frequency trading and arbitrage, contributing to the liquidity and efficiency of the markets but also raising questions about market dynamics and the role of automation in trading.
Solana’s rise to prominence in the stablecoin sector is notable. In January 2024, Solana surpassed both Tron and Ethereum to become the most active blockchain for stablecoin transfers. This surge is partly due to Solana’s high throughput capabilities, enabling rapid and cost-effective transactions, which have attracted a growing number of users and developers to its platform. Additionally, Solana’s stablecoin market capitalization experienced a significant increase, reaching $11.7 billion, a 116% rise over a 30-day period. This growth was influenced by various factors, including the introduction of meme coins such as TRUMP and MELANIA, which spurred increased activity and liquidity on the network.
Base, a layer-2 network developed by Coinbase, also demonstrated substantial growth. In the fourth quarter of 2024, Base’s stablecoin transaction volume surpassed that of Ethereum, highlighting the network’s scalability and appeal to users seeking efficient transaction solutions. Base attracted $7.8 billion in stablecoin inflows throughout the year, retaining $3.5 billion as net inflows. This influx indicates a strong confidence in Base’s infrastructure and its potential to support a wide range of decentralized applications and financial services.
The stablecoin supply expanded by 59% during this period, exceeding $200 billion and representing 1% of the total U.S. dollar supply. This increase signifies a growing trust in stablecoins as a medium of exchange and store of value within the digital economy. USDC emerged as the dominant stablecoin for on-chain transactions, accounting for 70% of the total transfer volume. However, its influence slightly waned in the third quarter due to a temporary decline in decentralized finance activity. Conversely, Tether’s USDT saw its total transfer volume more than double, although its market share decreased from 43% to 25% over the year.
The dominance of Ethereum and Tron in hosting stablecoins decreased from 90% to 83%, with networks like Solana, Base, Arbitrum, and Aptos capturing the remaining share. This diversification indicates a competitive landscape where multiple blockchains are enhancing their capabilities to attract stablecoin activity. The shift suggests that users and developers are exploring alternative platforms that offer unique advantages, such as lower fees, faster transaction times, or specialized features tailored to specific applications.
