Aevo Exchange

Aevo Exchange represents the evolution of Ribbon Finance — one of DeFi’s most significant derivatives experiments — from a passive options vault protocol into an active, order book-based derivatives exchange. Ribbon Finance, founded in 2021, pioneered decentralized options vaults (DOVs): smart contracts that automatically sold weekly covered call options on behalf of depositors, earning yield through option premiums. The DOV model was enormously popular, peaking at ~$300M TVL and demonstrating massive structural demand from both buyers (options market-makers) and sellers (yield-seeking depositors). But DOVs had a fundamental problem: by batch-auctioning all options at the same strike and expiry across dozens of competing protocols simultaneously (Ribbon, Friktion, Katana, ThetaNuts — all running similar vaults), the market became inefficient and premiums compressed to near-zero. The DOV model had commoditized itself into irrelevance. Ribbon’s team — recognizing this — pivoted dramatically, building the Aevo L2 from scratch as a fully featured on-chain options and perpetuals exchange with an order book, allowing market-makers to properly price options across the full strike/expiry surface rather than being forced into weekly batch auctions.

Key Facts

  • Founded: Ribbon Finance (2021) → rebranded to Aevo (early 2024)
  • Founders: Julian Koh, Ken Chan, Julien Bouteloup (initial)
  • L2: Aevo L2 — custom OP Stack rollup with faster block times
  • Products: Options (European, on major tokens), perpetual futures
  • Settlement: On-chain (Aevo L2); matching engine off-chain
  • Token: AEVO (formerly RBN — Ribbon Finance governance token, migrated to AEVO)
  • Funding: $8M Series A (Paradigm, Dragonfly Capital, Coinbase Ventures)

From Ribbon Finance to Aevo: The DOV Problem

The following sections cover this in detail.

Decentralized Options Vaults (2021–2022)

Ribbon Finance launched Theta Vault products — smart contracts that:

  1. Accept ETH, BTC, or USDC deposits from passive yield-seekers
  2. Every Friday, batch all deposited assets and auction off covered call options to institutional market-makers (via Paradigm OTC desk or open auction)
  3. Collect the option premiums as yield, distribute to depositors (~20-40% APY at peak)

Why DOVs worked initially:

  • Massive appetite from passive yield seekers (easy 20%+ APY)
  • Market-makers valued the reliable supply of standardized options (same strike, same expiry, same time)

Why DOVs stopped working:

  • Ribbon, Friktion (Solana), Katana (Polygon), ThetaNuts, Cega, Opyn Crab — all running similar vaults simultaneously
  • All auctions happened at similar times → market-makers were flooded with identical supply at the same time
  • Supply > demand → premium prices fell → vault APY fell to 2-5% → depositors left → TVL fell

By 2023, Ribbon Finance’s TVL had dropped from ~$300M to ~$30M. The DOV model was broken at scale.

The Aevo Pivot

Julian Koh and the Ribbon team made a decisive strategic choice: build an order book options exchange rather than continue optimizing DOVs. Their thesis:

  • The demand for DeFi options is real (proven by DOV TVL)
  • The supply model (DOVs) is broken
  • A full-featured options exchange (like Deribit, but on-chain) is the solution
  • Requires building a custom L2 for the low latency needed for options market-making

Aevo L2: A custom OP Stack rollup with:

  • Faster block times than Ethereum mainnet (sub-second finality for matching)
  • Lower gas costs for settlements
  • EVM compatible — existing Ethereum tooling works

Hybrid architecture: Off-chain order book matching (fast, no gas per trade) + on-chain settlement (trustless, non-custodial)

Products

The main product offerings are described below.

Options

European-style options on:

  • ETH (USDC-settled)
  • BTC (USDC-settled)
  • SOL, ARB, OP, and other major tokens (adding assets over time)

Strike and expiry matrix: Unlike DOVs that offer only one strike/expiry per week, Aevo maintains a full options surface:

  • Multiple strikes per expiry (ATM, OTM, deep OTM calls and puts)
  • Multiple expiries (daily, weekly, monthly, quarterly)
  • Market-makers can post bids/asks at any point on this surface

Market-maker program: Institutional market-makers (Genesis Trading, QCP Capital, etc.) receive gas rebates and fee discounts for providing liquidity on the options order book.

Perpetuals

Aevo added perpetual futures markets alongside options:

  • ETH-PERP, BTC-PERP, and expanding altcoin perp markets
  • Standard perpetuals with funding rate mechanism
  • Cross-margin with options (unified margin: options and perp positions share collateral)

Unified margin is a significant differentiator: a trader can delta-hedge an options position with a perpetual in the same account without moving collateral between protocols.

AEVO Token (formerly RBN)

Ribbon Finance’s original RBN governance token was migrated to AEVO as part of the rebrand:

  • RBN holders could migrate 1:1 to AEVO
  • AEVO utility: governance (parameter votes, asset additions), fee discounts (holding or staking AEVO reduces trading fees), potential future protocol revenue sharing

Aevo vs. Competitors

Dimension Aevo Deribit Lyra Finance (Derive.xyz) Premia Finance
Chain Aevo L2 (OP Stack) Offchain/ETH integration Custom L2 Arbitrum / multi
Options type European European European European
Order book Yes Yes Hybrid AMM+orderbook Isolated pool AMM
Perpetuals Yes Yes No No
Settlement On-chain L2 Primarily offchain On-chain L2 On-chain
Non-custodial Yes No (custodial) Yes Yes
Daily notional volume $50-200M (2024) $1-5B (dominant) $5-30M <$5M

Deribit remains the dominant options exchange by volume — Aevo is competing for the on-chain, non-custodial derivatives segment.

Social Media Sentiment

Aevo had strong launch momentum as a dedicated options and perpetuals L2, but CT sentiment has cooled as Hyperliquid and dYdX dominate perps volume. The AEVO token airdrop generated controversy. The pivot toward pre-launch token trading is watched as a differentiation play.
