Stablecoin Adoption Accelerates as Merchants Gain USDC Support on Solana and RLUSD Supply Shifts Between Ethereum and XRPL Networks

Summary

• Finassets.io added USDC payment support on Solana in August 2026, allowing merchants to accept the stablecoin alongside 70+ cryptocurrencies.
• Ethereum overtook the XRP Ledger in RLUSD supply, reaching $1.05 billion versus $941 million on XRPL.
• Solana maintains $695 million or more in USDC circulation with 280,000 active daily accounts and average fees of $0.00025.

Merchants gained direct USDC payment options on Solana through Finassets.io in August 2026. The integration lets businesses process payments in USDC on Solana using the same back office and payment buttons already available for over 70 other cryptocurrencies. At the same time, RLUSD supply crossed over, with Ethereum holding $1.05 billion compared to $941 million on the XRP Ledger.

These moves line up with wider stablecoin growth. Solana alone carries more than $695 million in USDC.

It processes transactions at an average fee of $0.00025 across 280,000 daily active accounts. The RLUSD shift happened amid minting on August 20, 2026. Ethereum saw 73.8 million RLUSD created and 23.5 million burned. XRPL recorded 36.1 million minted.

Context

Stablecoin use for payments keeps growing in 2026. Platforms cut costs and speed settlements for merchants. They tie into networks with big liquidity pools.

Solana's established USDC presence gave Finassets a ready base. The firm added support without new infrastructure.

RLUSD moves freely between the two networks. The recent flip in supply totals reflects mint and burn activity. It does not signal a permanent migration. Overall RLUSD stays nearly even.

Details

Finassets.io rolled out USDC on Solana payments through its existing merchant tools. Businesses can now accept and settle in the stablecoin without changing their checkout flow or back-office reporting. Multiple reports confirm the addition expands options already offered for dozens of other assets.

Ethereum's lead in RLUSD supply reached $1.05 billion against $941 million on XRPL. Daily mint and burn volumes on August 20, 2026, drove the crossover. Solana's separate USDC metrics show sustained activity with low fees and high account engagement.

The supply figures on both RLUSD networks sit close enough that minor daily flows can reverse the ranking again. No permanent structural change has been confirmed.

Outlook

Merchants and issuers keep testing Solana for USDC settlements. They track RLUSD volumes across Ethereum and XRPL for further shifts ahead.
