Which chain saw stablecoin surge?

TLDR

Solana (SOL) saw the most notable stablecoin surge this week.

1. Stablecoin market cap on Solana jumped $900 million in 24 hours to $15.3 billion, driven by Jupiters JupUSD launch (report).
2. Ethereum (ETH) set a record with $8 trillion stablecoin transfers in Q4 2025, showing broad on-chain settlement strength (summary).
3. This indicates deeper USD liquidity for DeFi, payments and settlement on these chains.

Deep Dive

1. Solana Spike

Solanas stablecoin cap rose sharply after Jupiter introduced JupUSD in partnership with Ethena.

1. The surge was $900 million in 24 hours, pushing Solanas stablecoin cap to $15.3 billion, with USDC at over 67% share (coverage).
2. Analysts noted Solana outpaced other networks in net inflows, contrasting with declines on Tron in the same window (context).

2. Ethereum Flows

Ethereum continues to dominate stablecoin settlement and transfer volume.

1. Stablecoin transfers on Ethereum reached $8 trillion in Q4 2025%%CKPROTECTED2%%, nearly double Q2, alongside peaks in daily transactions and active addresses (detail).
2. This reflects on-chain payment usage rather than just trading churn, reinforcing ETHs role as a settlement layer for digital dollars (overview).

3. Implications

Stablecoin growth on these chains signals a broader structural shift to on-chain finance.

1. Rising volumes and supply are consistent with projections that stablecoin payment flows could reach $56.6 trillion by 2030%%CKPROTECTED2%% (projection).
2. Near term, more USD liquidity typically improves depth, tighter spreads and faster settlement cycles for DeFi and payments.

Conclusion

Solana showed the clearest weekly surge signal in stablecoin supply, while Ethereum continues to lead in total stablecoin settlement volume. The combination suggests USD liquidity is consolidating around these rails, which could support deeper DeFi markets and payment use cases, with chain-specific trade-offs in speed, fees and ecosystem breadth.
