USDD said it has expanded its Vault to the Ethereum network, allowing users to mint the USDD stablecoin by depositing ETH or WBTC as collateral. The overcollateralized, user-controlled CDP model sets a minimum collateralization ratio of 130% and a stability fee as low as 4%. The move is aimed at improving capital efficiency by letting users unlock liquidity while retaining upside exposure to the underlying assets. It also positions USDD as evolving from a single stablecoin into a multi-chain yield infrastructure with on-chain yield opportunities.

Ripple’s XRP surged 20%, with the market widely attributing the rally to progress on an upgrade to the XRP Ledger (XRPL) lending protocol.

The integration also enables users to move directly into USDD Earn after converting.

Ethereum-based DeFi protocol OLY is set to open its token mint on Aug. 28, structuring rewards around protocol revenue rather than ongoing token issuance. The system routes income to stakers, liquidity, ETH-based vaults and OLY buybacks and burns.

Of ETH revenue, 34% is allocated to a staked ETH vault, 16% each to liquidity defense, a liquidity vault, direct staker payments and OLY buyback-and-burn, with the remaining 2% going to Genesis.
