Market-Neutral USD Vault

Overview

The ether.fi Market-Neutral USD vault provides a simple way for users to earn from a diversified basket of market-neutral yield opportunities, while getting exposure to the Ether.Fi ecosystem.

Users can deposit USDC, USDT, DAI, and USDe, which is then deployed to an evolving set of blue chip DeFi protocols. Initially the vault will utilize AAVE, Curve/Convex, Gearbox, and Pendle. As the vault scales, new yield sources such as Uniswap V3, Morpho Blue, Aura/Balancer may be added.

The vault is built using the Veda infrastructure. The strategy for the vault is provided by Seven Seas.

Technical Documentation

The Ether.Fi Market-Neutral USD vault was built using the Veda architecture. At a high level, the architecture uses a Merkle verification system to enforce constraints on the vault strategies: with every rebalance, the strategist must submit a Merkle proof demonstrating that the rebalance respects certain constraints. These constraints include only interacting with certain whitelisted protocols, assets, and even contract functions.

For more details on the smart contract architecture, see https://docs.veda.tech/

The initial set of supported protocols include:

• Ethena

• AAVE

• Pendle

• Gearbox

• Convex/Curve

• Morpho Blue

• Spark

Supported strategy assets include:

• USDe

• USDC

• USDT

• DAI

• sDAI

• PYUSD

• FRAX

The vault utilizes the risk monitoring system to interact with protocols Aave, Gearbox, and Convex/Curve. The contracts are listed below.
