Buy Dopex (DPX) with USD, EUR and Other Fiat Currencies
Dopex (DPX) is a DeFi token connected to decentralized options trading, Arbitrum-based liquidity pools, and crypto derivatives infrastructure. The project became known for building options products that aimed to make on-chain options more accessible for liquidity providers and traders.
For users who want to buy Dopex with USD, EUR, or other fiat currencies, the process usually starts with a crypto wallet, exchange, or fiat on-ramp that supports bank cards, Apple Pay, Google Pay, or crypto swaps. However, DPX requires extra attention because Dopex has rebranded to Stryke and introduced a migration from DPX and rDPX to SYK.
This article explains what Dopex is, how DPX worked, what changed after the Stryke migration, and which wallets can help users buy, store, send, or manage DPX-related assets.

What is Dopex (DPX)?
Dopex, short for Decentralized Options Exchange, is a decentralized options protocol originally launched on Arbitrum, an Ethereum Layer 2 network. The protocol was designed to provide on-chain options markets with better liquidity, capital efficiency, and lower trading costs for options buyers and sellers. IQ.wiki describes Dopex as a decentralized options protocol that uses option pools to enable buying and selling options in a capital-efficient way.
The project used a dual-token model. DPX was the limited-supply governance and protocol fee accrual token, while rDPX was used as a rebate token connected to losses and protocol incentives. IQ.wiki lists the total DPX supply as 500,000 tokens and explains that DPX was used for protocol and application-level governance.
Dopex became especially known for its Single Staking Option Vaults, or SSOVs. These vaults allowed users to deposit assets for a defined period and receive yield from options strategies. The goal was to make options liquidity easier to provide while reducing the complexity that often makes derivatives difficult for regular DeFi users.
The project was built on Arbitrum partly because options trading can be sensitive to transaction fees. In an earlier explanation cited by IQ.wiki, Dopex contributor Halko said that the team launched on Layer 2 because Ethereum trading fees were too expensive and lower costs were important for options trading profitability.
In 2024, Dopex began a major transition into Stryke. The Stryke blog announced that DPX and rDPX migration to SYK was live, with users able to migrate legacy tokens into the new token structure. The official Stryke migration post also stated that the migration window for DPX and rDPX would last 1.5 years.
The conversion model was clear: 1 DPX converts to 100 SYK, and 1 rDPX converts to 13.333 SYK. Stryke also stated that SYK would have a total supply of 100 million tokens, with 50 million representing DPX and 30 million representing rDPX in the conversion structure.
This means DPX should now be treated as a legacy asset connected to the previous Dopex ecosystem. Before buying, users should check whether a wallet or exchange still supports DPX, whether it supports SYK instead, and whether migration is still available.
Current market data also shows why caution is important. CoinGecko reported that DPX had very low recent trading volume, listed TVL data from DefiLlama, and showed that the latest recorded DPX price reflected limited recent trading activity rather than a highly liquid market.
The newer Stryke protocol is still tracked as an options protocol. DefiLlama describes Stryke as “previous Dopex” and lists it as a maximum-liquidity, minimal-exposure options protocol, with cumulative options notional volume of about $411.05 million and cumulative options premium volume of about $1.32 million at the time of review.
For buyers, DPX is not a stablecoin and should not be treated as a simple payment token. It is a DeFi derivatives governance asset from a protocol that has moved into a newer Stryke/SYK structure.

Buy DPX with Apple Pay
Buying DPX with Apple Pay depends on whether the wallet or payment provider supports DPX directly. Because DPX has migrated toward the Stryke/SYK ecosystem, direct Apple Pay purchases may be limited or unavailable on many platforms.
A practical route is to buy a more liquid asset first, such as ETH, USDT, USDC, or another supported token, then swap into DPX or SYK if a reliable route is available. Walletverse supports crypto purchases with Apple Pay, so users can use it as a mobile fiat-to-crypto entry point and then check available swap options.
Before confirming a transaction, review the asset name, network, provider fee, exchange rate, and whether the token is legacy DPX or the newer migrated asset.
Buy DPX with Google Pay
Google Pay can also be used to buy crypto in supported wallets and regions. The usual process is to choose a crypto asset, select Google Pay as the payment method, enter the fiat amount, and confirm the purchase through the wallet’s payment provider.
In Walletverse, users can buy crypto with Google Pay and manage assets in a non-custodial mobile wallet. If DPX is not available as a direct purchase option, users can buy another supported asset first and then check whether a DPX or SYK swap route is available.
This approach can be easier for beginners because it separates the fiat purchase from the token swap. However, users should still check fees, liquidity, and migration status before buying.
How to Buy Dopex (DPX) with Fiat?
Buying DPX with fiat requires extra care because the Dopex ecosystem has transitioned toward Stryke and SYK. The key step is to confirm whether you want old DPX specifically or the migrated token structure.
- Choose a crypto wallet. Select a wallet that supports fiat purchases, self-custody, and Ethereum or Arbitrum-compatible assets. Walletverse is a convenient option for mobile users because it supports Apple Pay, Google Pay, card payments, multiple fiat currencies, and 700+ crypto assets.
- Create or import your wallet. Install the wallet app and create a new wallet, or import an existing one using your recovery phrase. Store the recovery phrase offline and never share it in messages, screenshots, emails, or cloud notes.
- Select your fiat currency. Choose USD, EUR, GBP, CAD, AUD, INR, KZT, JPY, or another supported fiat currency. Available payment methods depend on your location and the wallet’s on-ramp provider.
- Search for DPX. Search for Dopex or DPX inside the wallet. If the token does not appear, check whether the platform supports Stryke or SYK instead.
- Check migration status. Review whether DPX is still supported or whether migration to SYK is required. The official Stryke migration post stated that DPX and rDPX holders could migrate to SYK during a defined migration window.
- Choose a payment method. Use Apple Pay, Google Pay, debit card, credit card, or another supported fiat payment method. Review fees, limits, expected delivery time, and the final amount before confirming.
- Buy a liquid asset first if needed. If DPX is not available for direct fiat purchase, buy ETH, USDT, USDC, or another supported asset first. This can make it easier to swap through Ethereum or Arbitrum-compatible routes.
- Swap to DPX or SYK if supported. Use a wallet swap feature or decentralized exchange route if available. Check contract details, slippage, gas fees, liquidity, and whether you are buying legacy DPX or the newer migrated token.
- Store the token securely. After purchase, store your assets in a wallet where you control access. Walletverse uses passcode and biometric authentication, while its self-custody model means users remain responsible for protecting their wallet credentials.
Why Wallet Choice Matters When Buying DPX
Wallet choice matters because DPX is no longer a simple, widely listed token. Buyers need to check network support, token migration status, liquidity, swap routes, contract addresses, and fees before making a transaction.
Walletverse can be useful for users who want a mobile-first crypto experience with fiat payment options, self-custody, biometric protection, Web3 access, and support for 700+ cryptocurrencies. For DPX buyers, the practical route may be to buy a liquid asset with fiat first and then check whether a safe DPX or SYK route is available.
Conclusion
Dopex (DPX) is a DeFi token from an Arbitrum-based options protocol that aimed to make decentralized options trading more liquid and accessible. The project introduced products such as option pools and Single Staking Option Vaults, while DPX served as the governance and fee-accrual token in the original ecosystem.
Today, DPX requires careful research because Dopex has transitioned into Stryke, with DPX and rDPX migration to SYK. This means users should check whether a wallet, exchange, or DeFi route supports old DPX, migrated SYK, or both.
Buying DPX with USD, EUR, Apple Pay, Google Pay, or other fiat methods depends on wallet support, regional payment access, liquidity, and token availability. Walletverse can help users enter crypto with fiat, manage assets in a non-custodial mobile wallet, and protect access with passcode and biometric authentication.
