Dopex (DPX) is a decentralized on-chain options protocol on Arbitrum — one of the earliest and most prominent DeFi-native options platforms — that enables option writing and purchasing through Single Staking Options Vaults (SSOVs, where depositors earn yield by passively writing covered options for a fixed epoch), Atlantic Options (a novel primitive allowing option holders to use purchased options as borrowing collateral within DeFi, enabling composable options strategies), and other structured derivative products, with DPX as the scarce governance and protocol revenue-sharing token (500,000 max supply) and rDPX as a secondary “rebate” token that accrues when options expire out-of-the-money and is later deployable as part of Dopex’s synthetic dollar system (DPXUSD).

How It Works
- Single Staking Options Vaults (SSOVs) — The core Dopex product. Depositors stake a single asset (ETH, WBTC, DPX, rDPX, RDNT, etc.) into an SSOV for a fixed epoch period (typically 1 week or 1 month). The SSOV writes (sells) covered call or put options at preset strike prices to option buyers. Depositors earn the option premium as yield. At epoch end, if options expire in-the-money, depositors’ collateral covers the difference; if out-of-the-money, depositors keep all premium yield.
- rDPX rebate mechanism — When options expire out-of-the-money (buyers lose), the protocol mints rDPX and distributes it to the option buyer as a partial rebate. This softens the loss for option buyers and incentivizes participation even in directional bets that didn’t pay off.
- Atlantic Options — An advanced primitive unique to Dopex. Atlantic put buyers can use their purchased puts as collateral to borrow the underlying asset from the put writer temporarily. This creates a composable “unlockable collateral” system where options interact with other DeFi protocols. For example, an Atlantic put on ETH can serve as liquidation insurance for a borrowing position in Aave or GMX.
- Dopex AMM (crvUSD-style) — Dopex developed concentrated AMM pools for options trading, allowing tighter spreads and capital efficiency for option market makers.
- DPX governance and fee accrual — DPX holders receive a share of protocol fees (option premiums collected by the protocol). DPX is also used in governance votes on supported assets, epoch durations, and protocol upgrades.
- Stryke (Dopex v2 rebrand) — In 2023–2024, Dopex evolved and rebranded its core options product to Stryke, emphasizing a new AMM-based options liquidity design for more capital-efficient option writing.

Use Cases
- Option writing (passive yield) — Deposit assets into SSOVs to earn premiums by writing covered calls or puts.
- Option buying — Purchase calls or puts on crypto assets at fixed strikes during SSOV epochs.
- Atlantic Options — Use purchased options as DeFi collateral for composable leverage/insurance strategies.
- DPX governance — Vote on SSOV asset additions, epoch parameters, fee rates, and protocol treasury.
History
- 2021-Q2 — Dopex launches on Arbitrum as one of the first decentralized options protocols on an Ethereum L2. The choice of Arbitrum is strategic — options require frequent computation (strike pricing, epoch settlement) that is cost-prohibitive on Ethereum mainnet. Arbitrum’s low fees make on-chain options viable.
- 2021-07 — DPX token launches. Max supply is set at 500,000 — an intentionally small supply mirroring BTC scarcity logic to create high per-token value and reduce dilution.
- 2021-2022 — Dopex becomes the largest options protocol by TVL on Arbitrum. SSOVs for ETH, BTC, DPX, and other assets attract hundreds of millions in TVL. The Atlantic Options product is announced as a novel DeFi composability tool and gains significant attention from DeFi researchers.
- 2022 — Dopex integrates with GMX, allowing Atlantic Options to serve as collateral for GMX leveraged positions — demonstrating the composable options concept in practice.
- 2022-2023 — Dopex TVL and DPX price decline significantly during the crypto bear market, consistent with most DeFi governance tokens. The protocol continues development. rDPX’s role as a backing asset for a synthetic stablecoin (DPXUSD) is designed to be a long-term deflationary mechanism for rDPX supply.
- 2023-2024 — Dopex rebrands its options AMM product to Stryke, launching a concentrated options liquidity model designed to improve capital efficiency for option writers. The team continues expanding SSOV assets and epoch structures.
Common Misconceptions
“DPX options are like Deribit or CME options.”
Dopex SSOVs are epoch-based, not continuous. Option buyers can only buy for fixed epochs (weekly or monthly) at fixed strikes preset by the vault. There is no continuous order book for real-time strike selection like Deribit. The SSOV model prioritizes simplicity and passive yield for depositors over trader flexibility.
“rDPX is just a secondary governance token.”
rDPX accrues continuously when options expire worthless. It serves as collateral backing for Dopex’s DPXUSD synthetic stablecoin system. rDPX therefore has protocol utility beyond governance, functioning as a redemption/rebate mechanism and system collateral.
Social Media Sentiment
Dopex has a dedicated following in the DeFi options space, which remains relatively niche compared to spot and perpetuals trading. DPX’s 500,000 max supply and fee-sharing model make it attractive to protocol maximalists. Atlantic Options are praised by DeFi researchers as genuinely novel derivatives design. The protocol is widely respected in Arbitrum ecosystem discussions. The Stryke rebrand and product evolution signal continued active development.
