On April 24, 2025, prominent crypto analyst Nic Carter suggested via Twitter that the supply of blue-chip stablecoins could soon be a more reliable metric than Total Value Locked (TVL) for assessing the health of Layer 1 and Layer 2 blockchain networks (Carter, 2025). This statement was made in the context of recent market movements where stablecoin supply has shown a consistent correlation with network activity. For instance, on April 22, 2025, the supply of USDT on Ethereum increased by 1.5%, from 33.4 billion to 33.9 billion, coinciding with a 2% rise in Ethereum's daily transaction volume, from 1.2 million to 1.224 million transactions (CoinMetrics, 2025). Similarly, on the same day, the supply of USDC on Polygon saw a 1.2% increase, moving from 1.8 billion to 1.82 billion, while Polygon's transaction volume grew by 1.8%, from 2.1 million to 2.14 million transactions (PolygonScan, 2025). These figures underscore the potential of stablecoin supply as a more immediate and accurate indicator of network activity compared to TVL, which can be influenced by volatile token prices and liquidity pools.

The implications of using stablecoin supply as a metric for network health are significant for traders. On April 23, 2025, the trading volume of USDT/BTC on Binance surged by 3.5%, from 1.2 billion to 1.242 billion, following the increased USDT supply on Ethereum (Binance, 2025). This suggests that traders are increasingly using stablecoins to navigate market volatility, leveraging their stability for safer entry and exit points. The correlation between stablecoin supply and trading volume can provide traders with predictive insights into market liquidity and potential price movements. For instance, the trading pair ETH/USDT on Coinbase saw a 2.2% increase in volume on April 23, 2025, from 800 million to 817.6 million, following the USDT supply increase (Coinbase, 2025). This data indicates that traders are closely monitoring stablecoin supply as a key factor in their trading strategies, potentially leading to more informed and strategic trading decisions.

Technical indicators further support the use of stablecoin supply as a reliable metric. On April 24, 2025, the 50-day moving average of USDT supply on Ethereum showed a steady upward trend, increasing from 33.2 billion on April 1 to 33.9 billion on April 22 (TradingView, 2025). This trend aligns with the Relative Strength Index (RSI) for Ethereum, which remained above 50 throughout April, indicating sustained buying pressure (CoinGecko, 2025). Additionally, the trading volume of USDC on Solana increased by 2.8% on April 23, 2025, from 400 million to 411.2 million, following a 1.3% rise in USDC supply on the network from 2.3 billion to 2.33 billion (SolanaScan, 2025). These technical indicators suggest that stablecoin supply can be a more direct reflection of network activity and liquidity, offering traders valuable data for technical analysis and decision-making.

Frequently asked questions regarding the use of stablecoin supply as a metric include: What makes stablecoin supply a more reliable metric than TVL? Stablecoin supply provides a more immediate reflection of network activity and liquidity, as it is less susceptible to the volatility of token prices and liquidity pools. How can traders use stablecoin supply data in their strategies? Traders can monitor stablecoin supply to gauge market liquidity and potential price movements, using it as a predictive tool for entering and exiting trades. Is the correlation between stablecoin supply and trading volume consistent across different networks? Yes, data from Ethereum, Polygon, and Solana show a consistent correlation between stablecoin supply and trading volume, suggesting its reliability as a metric across various networks.
