DAY 348 // DEFI UPDATE @Uniswap launched the VolatilePair Hook on Ethereum mainnet, starting with ETH/USDC. A hook is an add-on that changes how a Uniswap v4 pool behaves. It sets a separate fee for each side of the trade and shifts both with the market. After a big move, trades that push price back pay a temporary fee. Volatile pairs did over $500B in volume on Uniswap this year. @merkl_xyz is distributing 20,000 USDC in rewards on the new ETH/USDC VolatilePair pool until 28 October. The @pendle_fi Ecosystem High Yield USDC vault is live on @Morpho. It is co-curated by Pendle and Armitage, the vault curation arm of @wintermute_t. Co-curated means both teams pick where the vault's money goes. At launch it allocates across three PT markets: PT-reUSD, PT-USDat and PT-USD3. A PT (principal token) locks in a fixed rate until maturity. It runs alongside the existing Ecosystem USDC vault. Apyx launched new $apxUSD and $apyUSD markets on Pendle, with maturity on 10 February 2027. PTs offer fixed rates up to about 15% APY. YTs (yield tokens) offer leveraged yield plus points. LPs, the liquidity providers, are also open. Apyx also published its September attestation from Wolf & Company. An attestation is an outside firm's check of the reserves. It verifies reserves and collateral for its products. @LiquityProtocol's ysyBOLD went live as collateral on @InverseFinance FiRM. It enables fixed rate DOLA borrows against about 5% compounding yield, with borrower incentives through Merkl. The market reached $1M TVL in under 24 hours. TVL is total value locked, the money deposited in a market. @monad confirmed the integration of @onrefinance's ONyc, a reinsurance yield token, through @plumenetwork Vaults. This expands RWA access from Solana to Monad. RWAs are real-world assets turned into tokens. Morpho powered yield is now available privately to millions of @deel users through Tempo Zones. Idle balances are routed to @SentoraHQ curated Morpho vaults. Stocks on @aave now earn 3% yield, and Merkl distributes the rewards. FX100 from @protocol_fx launched race season. It is a six week Guild quest campaign on testnet where traders earn XP that counts toward mainnet. It also highlights the 15 minute liquidation protection window.
