The global financial landscape witnessed a seismic shift in 2024 as stablecoins outpaced traditional payment giants Visa and Mastercard, recording a staggering $27.6 trillion in transfer volume. This milestone, revealed in a comprehensive report by crypto exchange CEX.IO, marks a pivotal moment in the evolution of digital finance—highlighting the growing dominance of blockchain-based transactions over legacy payment systems.
With high-speed, low-cost networks like Solana leading the charge, stablecoins have cemented their role as essential tools in decentralized finance (DeFi), cross-border remittances, and everyday trading. The $27.6 trillion figure exceeds the combined transaction volume of Visa and Mastercard by 7.68%, underscoring a broader trend toward digital asset adoption.
Despite a temporary slowdown in Q3 due to broader market corrections, stablecoin activity remained resilient throughout the year. This consistency reflects increasing institutional and retail confidence in stable digital assets as reliable mediums of exchange.
Stablecoin Supply Reaches New Heights
The total stablecoin supply expanded by 59% in 2024, surpassing $200 billion for the first time. This surge means stablecoins now represent 1% of the total US dollar supply—a significant jump from just 0.63% at the beginning of the year.
This growth isn't just symbolic; it reflects real-world utility. From remittances to DeFi lending, stablecoins are being used to move value faster and cheaper than traditional banking rails. As legacy providers like Western Union and MoneyGram see declining app usage, users are increasingly turning to digital dollars for speed, transparency, and accessibility.
USDC Takes the Lead Amid Solana’s Rise
Circle’s USDC emerged as the most dominant stablecoin for on-chain transactions, accounting for 70% of total transfer volume in 2024. While its influence dipped slightly in Q3 due to reduced DeFi activity, USDC regained momentum as ecosystem confidence returned.
Meanwhile, Tether’s USDT, the largest stablecoin by market capitalization, saw its transfer volume more than double. However, its market share declined from 43% to 25%, signaling a diversification in user preference and growing competition.
The most notable shift occurred at the blockchain level: Solana overtook both Tron and Ethereum in January 2024 to become the most active network for stablecoin transfers. This rise was fueled by Solana’s high throughput, low fees, and booming DeFi ecosystem.
By year-end, 73% of Solana’s stablecoin supply was tied to USDC transactions. According to CEX.IO, this growth mirrored Solana’s broader ecosystem expansion:
“This increase aligned with Solana’s overall ecosystem growth, as stablecoins on the network were predominantly used for DeFi and other dApp activities.”
Bots Drive the Majority of Stablecoin Volume
One of the most surprising findings from the report was the overwhelming role of automated trading systems—bots—in driving stablecoin volume. In 2024, 70% of all stablecoin transactions were bot-driven, with unadjusted volumes (largely reflecting automated activity) making up 77% of total transfers.
This represents a fourfold increase from 2023, highlighting the maturation of blockchain ecosystems where automation enhances efficiency rather than merely inflating numbers.
On networks like Ethereum, Base, and Solana, bots dominated activity—especially where USDC is widely used. In fact, on USDC-centric chains like Solana and Base, over 98% of stablecoin transactions were unadjusted, meaning they were primarily executed by bots.
These automated systems perform critical functions:
- Arbitrage trading across decentralized exchanges (DEXs)
- Execution of recurring smart contract operations
- Gas fee management for user transactions
While concerns persist about bots enabling manipulative practices like frontrunning and sandwich attacks, CEX.IO emphasized their constructive role:
“As a result, bot dominance in stablecoin transactions could also represent the maturation of certain networks.”
The rise of meme tokens further amplified bot activity. In December alone, memecoins accounted for 56% of Solana’s DEX trading volume, creating fertile ground for automated trading strategies.

What’s Next for Stablecoins in 2025?
Stablecoins have firmly established themselves as core liquidity instruments in DeFi, trading, and international payments. Looking ahead to 2025, this trend is expected to accelerate—particularly following the Bitcoin halving cycle, which historically correlates with increased capital inflows and trading activity.
Continued Supply Expansion
Historical patterns suggest that stablecoin growth doesn’t halt during market downturns. For example, in 2022, supply continued rising until March—five months after the market peak. This resilience indicates that demand for digital dollars may remain strong even amid volatility.
Regulatory Pressures and Network Shifts
Tether (USDT) faces increasing regulatory scrutiny, especially in Europe under MiCA (Markets in Crypto-Assets Regulation). Some platforms have already begun delisting USDT to ensure compliance. This could weaken Tron’s dominance—long a hub for USDT transactions—and open opportunities for competitors.
At the same time, Ethereum’s upcoming Pectra upgrade, expected in March 2025, aims to improve scalability, reduce gas fees, and enhance user experience across Layer 1 and Layer 2 networks. If successful, it could reposition Ethereum as a leading platform for stablecoin issuance and usage.
Frequently Asked Questions (FAQ)
Q: How did stablecoins surpass Visa and Mastercard in transaction volume?
A: Stablecoins achieved a $27.6 trillion transfer volume in 2024—7.68% more than Visa and Mastercard combined—driven by high-speed blockchains like Solana and widespread use in DeFi and trading.
Q: What role do bots play in stablecoin transactions?
A: Bots accounted for 70% of stablecoin volume in 2024, primarily performing arbitrage, smart contract executions, and gas optimization. On networks like Solana and Base, over 98% of activity was bot-driven.
Q: Why is USDC gaining market share over USDT?
A: USDC benefits from stronger regulatory clarity, integration with high-performance blockchains like Solana, and growing trust among institutional users—factors contributing to its 70% share of transfer volume.
Q: Is the $27.6 trillion figure inflated by automated transactions?
A: Yes, unadjusted volumes—including repetitive bot trades—made up 77% of total transfers. However, these activities also reflect network maturity and real economic utility in DeFi ecosystems.
Q: Could stablecoins replace traditional payment networks?
A: While full replacement is unlikely soon, stablecoins are already outperforming legacy systems in speed and cost-efficiency—especially for cross-border payments and digital asset settlements.
Q: What impact will upcoming Ethereum upgrades have on stablecoins?
A: The Pectra upgrade in 2025 aims to reduce fees and improve scalability, potentially boosting Ethereum’s appeal as a stablecoin hub—especially for Layer 2 solutions.
