PYUSD, PayPal's stablecoin, has reached a significant milestone by hitting a $1 billion supply, with the majority of its supply residing on the Solana blockchain. Solana holds a 64% market share of PYUSD over Ethereum's 36%, making it the primary home for the stablecoin. The increase in PYUSD supply is partly attributed to its growing use as stable collateral on lending protocols and decentralized exchanges. Lending and borrowing capacities for PYUSD have been increased on marginfi, allowing up to $60 million in lending, currently yielding 15.09%. Additionally, $1.2 million per week is being used to bootstrap PYUSD's adoption on Kamino, indicating aggressive growth strategies. PYUSD is poised to overtake USDT as the second largest stablecoin on Solana. There is speculation about who is funding the current yield for supplying PYUSD, with possibilities including PayPal or the Solana Foundation. Reports suggest that $1.5m+/week is being spent to incentivize PYUSD's growth.
