Bitfinex-Backed Stable Adds PayPal’s PYUSD to Its Ecosystem

In a pivotal fusion of legacy fintech and blockchain innovation, PayPal Ventures has injected strategic funding into Stable, the Bitfinex-backed Layer 1 network optimized for stablecoin transactions, enabling seamless integration of PayPal USD (PYUSD) on the Stablechain. Announced September 22, 2025, the collaboration unlocks permissionless use of PYUSD—PayPal’s dollar-pegged stablecoin—for commerce, peer-to-peer payments, and remittances, leveraging LayerZero’s bridging tech for cross-chain liquidity.

Stable, which emerged from stealth in July with a $28 million seed round co-led by Bitfinex and Hack VC, powers transactions via USDT as its native gas token, ensuring fee predictability and sub-second finality on an EVM-compatible chain. The platform targets institutional hurdles like volatile fees and slow settlements, positioning itself as the “enterprise lane” for stablecoin adoption in underserved markets. PYUSD, launched in 2023 with Paxos and boasting a $1.4 billion market cap (ranking 11th among stablecoins), now joins USDT in Stable’s ecosystem, broadening access for users familiar with PayPal’s 400 million+ wallet base.

“This underscores our drive to amplify PYUSD’s utility across ecosystems,” stated David Weber, PYUSD ecosystem head, emphasizing real-time, low-cost transfers. For Bitfinex—closely tied to Tether’s $172 billion USDT—the move diversifies liquidity amid a $3 trillion crypto market, where stablecoins underpin 70% of trading volume.

The partnership signals a maturing stablecoin sector, mirroring Circle’s Arc and Ripple’s RLUSD pushes, while exploring on/offramps and future payment products. As Bitcoin eclipses $115,000, this bridge could catalyze DeFi growth and tokenized assets, but risks like regulatory scrutiny persist for fiat-pegged tokens.

For investors, Stable’s roadmap—featuring AI-driven wallets and parallel execution—hints at explosive potential, blending TradFi trust with blockchain speed.
