Stablecoin-Focused Crypto Portfolios to Watch: ETH, SOL, and XRP’s Role Explained

The U.S. crypto industry hit a milestone this week as the Senate passed the GENIUS Act, a bill that creates a clear regulatory framework for U.S. dollar-pegged stablecoins. The bill, officially titled the Guaranteed E-Money Innovation and US Dollar Security (GENIUS) Act, received support from both sides of the political aisle — with several Democrats joining Republicans to push it through. It now heads to the House, where expectations are high for swift approval, and eventually to President Trump’s desk for signature.

Industry experts are now suggesting portfolio frameworks built around assets that directly support or benefit from the growing stablecoin and payment infrastructure.

What This Means for Crypto Portfolios

As stablecoins secure a regulatory green light, crypto investors are already adjusting their strategies to tap into this fast-growing sector. On The Paul Barron Network, the analyst advised a fresh portfolio approach centered around assets tied to payment infrastructure and stablecoin ecosystems.

In this updated model:

• Ethereum (ETH) would hold the largest share at 50%, since it remains the primary network for stablecoin transactions and decentralized finance activity.
  
• Solana (SOL) follows with 25%, capitalizing on its rapid adoption in retail payment platforms.
  
• XRP takes a 10% allocation, with potential to expand its utility in point-of-sale transactions alongside its established banking use case.

Layer-2 solutions such as Optimism, Arbitrum, and Polygon collectively account for around 9%, providing scalable, low-cost infrastructure for stablecoin-based payments.

Stellar (XLM), long a staple for cross-border transfers, is recommended at 2.5%, especially as it gains momentum with PayPal-backed payment integrations.

A final portion is reserved for emerging growth chains like Avalanche (AVAX), Sui (SUI), and Aptos (APT), which could capture market share as the payment and stablecoin narrative accelerates.

The Payment Boom Is Here

Experts say the passing of the GENIUS Act and rising money market yields have sparked a wave of investor interest in payment-focused crypto projects. With regulated stablecoins inching closer to mainstream adoption, portfolios built around this sector could see major upside in the months ahead.
