Overview

AevumFi is a financial operating system for Robinhood Chain. It has five modules, settled in USDG or WETH:

• Omni-Vault — an ERC-4626 vault on USDG. Depositors receive afUSD and take the other side of every perp trade: the vault earns trading fees, funding and trader losses, and pays trader profits.
• Synthetic index perps — isolated-margin perpetuals on 34 global equity indices, from the S&P 500 to the Nikkei 225, with up to 20× leverage, skew-based funding, limit and stop orders, and on-chain liquidations.
• Dark pool — a sealed-order batch auction for WETH/USDG. Orders are committed as hashes, revealed only after the batch closes, and crossed pro rata at the oracle mid.
• Liquidity ladders — pools whose liquidity sits on price rungs, and user-owned vaults that keep a ladder of bids and asks around the price, re-centred by a restricted operator under on-chain volatility gating, with fees compounded into afUSD.
• Launchpad — permissionless fixed-supply launches whose whole supply goes on a locked ladder, with creator fees routed through an Autonomous Capital Route: an AI agent's compute stream, an NFT floor backstop, or a buyback & burn ladder.

The vault, perps and dark pool are priced by one signed oracle; ladders price themselves. Two services run alongside the contracts: the price service, which signs market data for the oracle, and the keeper, which liquidates, executes orders, settles batches, re-centres ladders it operates and routes launch fees. Both only do things anyone is allowed to do — except re-centring, which only the operators vault owners choose may do.

What problems it addresses#

• Rented liquidity. Perp venues on new chains usually rely on market makers who keep the spread. The Omni-Vault is the counterparty instead, so what traders pay goes to depositors.
• Fragmented index access. Trading 34 benchmarks normally means a broker account per country and currency. Here every market is margined and settled in the same dollar, from one wallet.
• Visible order flow. Public-mempool swaps get front-run and sandwiched, and private venues are gated to block desks. The dark pool hides direction and size until a batch closes, and prices every batch from outside the pool.

How the pieces fit#

The price service reads index and ETH quotes, signs them as one EIP-712 batch, and hands the batch to whoever needs it. A trader includes it in the same transaction as their trade; the oracle checks the signatures and freshness before any contract uses a price. The perp engine settles every position against the Omni-Vault, and the dark pool settles each batch against its own balances. See architecture for the full picture.

Using the Terminal#

Connect the wallet you already use — Phantom, MetaMask, Rabby, Coinbase Wallet or any WalletConnect wallet — on whatever network it is on. Sign one message (free: it sends no transaction) and your AevumFi account opens. That account is what holds your balances and positions in the Terminal and signs your actions, so your wallet never has to switch networks or approve each step. The same wallet always opens the same account, on any device. New accounts get their gas automatically.

The account has its own address, which is what block explorers show for your transactions. It lives in the Terminal: don't send funds to it from elsewhere.
