PayPal USD (PYUSD)

Stablecoin adoption is accelerating, but every new issuer also fragments liquidity, capital, and market efficiency across the ecosystem.

This isn't just a partnership between @sparkdotfi, @Uniswap, and @SkyEcosystem. It's a blueprint for the next generation of stablecoin infrastructure.

The next challenge isn't issuing more stablecoins. It's coordinating liquidity across hundreds of issuers.

So what makes this model different? Let's break it down.

—
● The Next Phase of Stablecoin Infrastructure
The stablecoin market is evolving through three distinct phases.
• Phase 1 (2020-2025): Launch stablecoins.

• Phase 2 (Today): Hundreds of companies are launching their own stablecoins.

• Phase 3 (Next): Build a shared liquidity layer that enables stablecoins to seamlessly exchange across issuers.

Spark believes the next phase is a programmable FX layer where banks, fintechs, exchanges, and payment providers connect to shared liquidity instead of rebuilding it from scratch.

● The Stablecoin Expansion Is Already Underway

Stablecoins processed over $28T in transaction volume during 2025, while global cross-border payment flows are projected to exceed $320T by 2032.

That's why nearly every major financial institution and fintech is entering the market:
• @PayPal ( $PYUSD )
• @Ripple ( $RLUSD )
• @RobinhoodApp
• @Revolut
• @deel
• @Visa
• @Mastercard
• @stripe
• @bbva
• @BNPParibas
• @mufgcr_official

The market is no longer asking if stablecoins will succeed.
The real question is how hundreds of stablecoins issued by different institutions will interact.

—
● The Real Bottleneck Isn't Liquidity
The biggest misconception is that stablecoins need more liquidity. The real problem is fragmented liquidity spread across isolated issuers, pools, and trading venues.

Every new issuer must build LP incentives, market makers, liquidity pools, inventory, and trading relationships, repeating the same work while fragmenting capital.

Current model:
Launch stablecoin -> Bootstrap liquidity -> Find market makers -> Pay LP incentives -> Manage inventory -> Scale

Shared model:
Launch stablecoin -> Connect to Spark -> Connect to Uniswap -> Access shared liquidity -> Focus on users -> Scale

Spark coordinates liquidity across the network, allowing issuers to connect to shared liquidity instead of building it independently.

—
● The Stablecoin FX Layer
The core idea is simple: stablecoins need a shared FX layer. Instead of every issuer building separate liquidity, they connect to a common liquidity network.

Instead of:

• $PYUSD ↔ $USDC

• $USDC ↔ $RLUSD

• $RLUSD ↔ $USDT

• Future stablecoins

A shared liquidity layer sits beneath them all while users continue using their preferred stablecoin.

@Uniswap v4 Hooks make liquidity programmable through custom rules and allocation logic.

—
● How Each Protocol Fits Together
• @sparkdotfi : Coordinates capital allocation, risk, inventory, and liquidity across the network using its experience in lending and savings.

• @Uniswap v4: The execution layer that enables programmable liquidity through Hooks.

• @SkyEcosystem : Provides the network's liquidity foundation, with USDS as the base asset backed by deep liquidity and savings infrastructure.

The first deployment migrates ~$150M into the $USDS/ $USDT and $USDS/ $PYUSD pools, delivering deeper liquidity, lower slippage, and better execution.

As more issuers join, each new stablecoin adds liqui
dity, improves execution, and strengthens the network.

The next competitive advantage isn't issuing another stablecoin. It's coordinating liquidity across hundreds of issuers.
