PayPal has announced a strategic partnership with the decentralized finance (DeFi) protocol Spark to enhance liquidity for its US dollar stablecoin, PayPal USD (PYUSD). Since its introduction on SparkLend, a lending market centered on stablecoins, PYUSD has already garnered over $135 million in deposits.
SparkLend, launched in 2023 and rooted in the MakerDAO ecosystem, was later integrated into its successor entity, Sky. It operates on the Spark Liquidity Layer, which boasts an impressive backing of over $8 billion in stablecoin reserves, according to the protocol’s disclosures.
Sam MacPherson, co-founder and CEO of Phoenix Labs—an essential contributor to Spark—revealed that PayPal opted for Spark due to its unique position as the only large-scale DeFi protocol capable of effectively deploying capital into other protocols. He emphasized the future potential of DeFi, stating, “DeFi will be the rails for all finance in the future, so focusing on that makes a lot of sense as there is massive growth potential.”
Spark serves as a non-custodial lending platform where users can deposit stablecoins into Spark Savings and earn non-rebasing yield tokens. These tokens, according to data from Messari, maintain a fixed balance while increasing in value over time, with yields determined by governance from Sky and funded through protocol-generated revenues.
PYUSD was added to SparkLend after successfully passing the protocol’s rigorous risk assessments.
The stablecoin market is experiencing a significant surge, with its market capitalization approaching $300 billion. This growth follows the impending enforcement of Europe’s Markets in Crypto-Assets Regulation (MiCA) in January and the recent passage of the Genius Act in the U.S. in July, which also relates to stablecoin regulation.
As reported by DefiLlama, stablecoin market capitalization has risen by over $90 billion since the beginning of the year. This overall expansion aligns with the increasing demand for yield-bearing stablecoins. Other stablecoins, such as Ethena’s USDe and Sky’s USDS, have experienced remarkable momentum, with USDe’s supply growing by 70% and USDS expanding by 23% since the Genius Act was enacted.
In a similar move, Coinbase has revitalized its Stablecoin Bootstrap Fund to inject liquidity into USDC across various DeFi platforms like Aave and Morpho, although the size of the fund has not been disclosed.
A recent Binance Research report highlighted how accelerating stablecoin adoption is positioning DeFi lending protocols to cater to institutional participation. DeFi lending markets have expanded by over 70% year-to-date as of September, with institutional demand identified as a significant contributing factor.
This evolving landscape has been described as “stablecoin 2.0.” Unlike “first-generation” tokens like Tether’s USDt (USDT), which primarily focused on digitizing the US dollar, this new wave of stablecoins aims to create added utility by combining liquidity with yield generation.
