This integration makes ZoroSwap accessible to a much wider audience: you can now sign in with your email, Google, Twitter, or Telegram account and start swapping on Miden within seconds.

The Problem with Self-Custodial Wallets

Self-custodial wallets (like the Miden browser extension) give you full control over your private keys. That is a powerful guarantee, but it comes with real trade-offs:

• Seed phrases are a liability. You must write down and securely store a seed phrase. Lose it, and your funds are gone forever. Store it carelessly, and anyone who finds it has full access to your assets.

• You are locked to a single device. Your wallet lives in your browser extension on one specific machine. Want to swap from your laptop at home and your desktop at work? You need to manage the extension and your seed phrase across each device.

• The onboarding is steep. For users coming from traditional finance or Web2 apps, installing a browser extension, generating keys, and backing up a seed phrase is an intimidating first experience.

These are not hypothetical concerns. Poor key management is one of the leading causes of lost funds in crypto. And onboarding friction is one of the main reasons people never try DeFi at all.

How Para Works

Para takes a fundamentally different approach to key management using distributed Multi-Party Computation (MPC). Instead of generating a single private key and placing the entire burden of securing it on you, Para splits key material into multiple key shares that are distributed across separate parties:

1. One share is stored in your device's secure enclave, protected by a passkey tied to your biometrics or device PIN.

2. One share is held by Para's infrastructure.

3. One share is an encrypted recovery share, generated during setup.

A transaction can only be signed when multiple shares collaborate through a cryptographic signing protocol. No single share is ever sufficient on its own.

Why Para Cannot Access Your Funds

This is the critical question, and the answer lies in the MPC architecture: Para only ever holds one key share. That single share is mathematically useless without your device share. Para cannot reconstruct your full private key, cannot sign transactions on your behalf, and cannot move your funds. Even in a worst-case scenario where Para's servers were compromised, an attacker would only obtain one share, which reveals nothing about your actual private key.

This is not a custodial wallet where you trust a company to hold your keys. It is a non-custodial design where control is split so that only you can authorize transactions, but you do not carry the full burden of securing a single secret.

Why You Are Not Locked to One Device

With a traditional self-custodial wallet, moving to a new device means exporting your seed phrase and importing it elsewhere, a process that is both inconvenient and risky. Para solves this through passkeys.

When you sign up with Para, your key share is tied to a passkey stored in your device's secure hardware enclave. Modern operating systems (iOS, Android, macOS, Windows) can sync passkeys securely across your devices through your platform account (e.g., iCloud Keychain or Google Password Manager). This means:

• You can log into ZoroSwap from your phone, your laptop, or any other device where your passkeys are available.

• Your key share travels with you seamlessly, without you ever having to copy, export, or manually transfer any secret material.

• The key share never leaves the secure enclave in plaintext. It is protected by your biometric authentication (Face ID, fingerprint, etc.) or device PIN at every step.

What if you are on a device that doesn't have your passkey? This can happen when your passkeys haven't synced. For example, if you are switching between Apple and Android ecosystems, or logging in from a friend's computer. In that case, Para utilizes the recovery secret that was generated in the initial wallet setup. Para itself does not store this secret. If you ever need to access your wallet from a device where your passkey is not available, you can use that recovery secret to initiate recovery through Para, verify your identity via two-factor authentication, and register a new passkey on the new device.

The result: you get the convenience of accessing your wallet from any device, without compromising on security and without ever exposing a seed phrase.

What This Means for ZoroSwap Users

When you connect to ZoroSwap, you now see two options:

• Miden Wallet: the Chrome browser extension for users who prefer traditional self-custody.

• Para Wallet: email or social login for users who want a seamless experience without managing extensions or seed phrases.

Both options give you full access to ZoroSwap's features. Para wallet users also get a built-in note claiming flow that handles Miden's UTXO-based transaction outputs through a simple UI action.

ZoroSwap is a DEX built on Miden, a zero-knowledge rollup that brings privacy and scalability to Ethereum. Para's embedded wallet infrastructure is a natural fit for Miden's vision of making privacy-preserving DeFi accessible to everyone. Learn more about the Miden x Para integration on the Miden blog.

Zoroswap is set to become the central liquidity hub on Miden, combining the best of both passive and active market-making paradigms. The project is proudly supported by a development grant from Miden, underscoring its importance to the broader Miden ecosystem.

A Hybrid Model for the Future of Liquidity

Zoro introduces a novel dual architecture AMM that brings together two complementary models:

• Passive Uniswap-type pools designed for long-tail assets, ensuring efficient and permissionless on-chain price discovery

• Actively priced pools for major assets such as crypto blue chips and fiat-pegged stablecoins, ensuring maximal capital efficiency and profitable liquidity provisioning - an approach recently validated by different “Prop AMMs” such as HumidiFi, Tessera V (Solana), or Nabla Finance (EVM)

This hybrid structure allows Zoro to combine the permissionless token listing of passive AMMs for longtail assets with the efficiency and profitability of active market-making for bluechip assets. The result is a flexible one-stop liquidity layer, offering the best pool architecture for every asset.

Built on the Strengths of Miden

Zoroswap is deeply integrated with the Miden blockchain, leveraging its unique technical advantages, which include:

• Unparalleled scalability, enabling high-throughput, low-cost transactions

• Off-chain order matching, preventing on-chain congestion while allowing complex market strategies to execute seamlessly

• Compliant private transactions, making Zoro suitable for both individual DeFi users and institutions seeking regulatory-compliant privacy
  

Built on Expertise

The team behind Zoro looks back on several years of experience with building highly profitable onchain market making strategies, innovative AMM designs, inventory risk management and zk applications. The Miden blockchain now finally provides the perfect technical foundation to combine those building blocks into this powerful new AMM primitive.

"True spot and derivative TradFi-grade trading - private, fast and scalable - has been only really available on CEXes. Not to diminish great accomplishments of protocols like Hyperliquid, HumidiFi or Railgun, but none of them had all the required features. Miden's (compliant) privacy, extreme parallelism and edge execution fix that, enabling DEXes to really compete with CEXes without sacrificing fundamental features like self-custody, decentralisation and lack of intermediaries. Oracle-priced AMMs like Zoro are uniquely poised to leverage these features to the fullest."
Mieszko Manijak, Co-Founder Zoro

"We’re very excited to support Zoro, which gives Miden both a foundational AMM and a forward-looking one in the same package. Zoro is a great example of the kind of differentiated financial products that become possible thanks to Miden's privacy, and that's what we want to see as we approach mainnet."
Azeem Khan, Co-Founder Miden
