Particle Network vs Arcana Network: Web3 Auth Infrastructure

Core Advantage: A single, chain-agnostic smart account powered by MPC-TSS. This enables gasless transactions and social logins (Google, Apple, Discord) across 50+ EVM and non-EVM chains. This matters for mass-market dApps that need to abstract away blockchain complexity from end-users.

Core Advantage: Bundles Auth, Node RPC, and Data APIs (NFT, Token, Transaction) into one SDK. This reduces integration complexity and vendor lock-in. This matters for rapid prototyping and teams wanting a unified backend without managing multiple service providers.

Core Advantage: Built on a decentralized storage layer with privacy-preserving data access control. User data is encrypted, sharded, and stored across a node network. This matters for high-security applications handling sensitive data (e.g., healthcare, enterprise, confidential DeFi).

Core Advantage: Fine-grained, programmable data access policies managed on-chain. Users can grant/revoke permissions per application and data type. This matters for compliance-heavy use cases (GDPR, HIPAA) and protocols building a user-centric data economy.

• Consumer-Facing dApps & Games: Prioritizing seamless onboarding via social login.
• Multi-Chain Aggregators & Wallets: Needing a single user identity across many blockchains.
• Speed-to-Market Projects: Wanting a full-stack, managed Web3 backend service.

• Data-Sensitive dApps: Handling medical records, enterprise documents, or private credentials.
• Compliance-First Platforms: Requiring auditable, user-controlled data consent logs.
• Storage-Centric Protocols: Where decentralized, encrypted file storage is a core requirement.

Full-stack abstraction: Offers a unified SDK for MPC-TSS wallets, social logins, and gas sponsorship via the Particle Auth Service. This reduces integration time from weeks to days for apps like StepN and Bybit Web3.

Key Metric: Supports 50+ EVM and non-EVM chains (Solana, TON, Bitcoin L2s) natively, providing broader chain coverage than most competitors.

Bundled gas sponsorship: Native paymaster integration allows projects to abstract gas fees completely, a critical feature for mainstream user onboarding.

Unified Account Abstraction: Combines MPC wallet management with ERC-4337 smart accounts, enabling features like social recovery and batch transactions without managing separate infrastructure.

Auth + Storage stack: Unlike pure auth providers, Arcana bundles decentralized storage and data privacy layers via its Arcana Store. This is ideal for dApps handling sensitive user data (e.g., health records, private documents).

Architecture: Operates its own validator set for the auth layer, appealing to teams prioritizing decentralization over pure SaaS convenience.

Fine-grained permissions: Provides a programmable data access layer where users can grant/revoke app permissions at a granular level, auditable on-chain.

Use Case Fit: Best for enterprise B2B applications, credentialing platforms, and any dApp where data sovereignty and compliance (like GDPR) are non-negotiable requirements.

Single integration for 30+ EVM and non-EVM chains: Particle's Smart Wallet-as-a-Service (WaaS) provides a unified SDK, enabling developers to deploy on Solana, Polygon, Arbitrum, and others without managing separate auth flows. This matters for rapid multi-chain deployment and reducing integration complexity.

Gasless, policy-controlled user sessions: Particle's session keys allow users to pre-approve transactions for specific dApps and conditions (e.g., spending limits, time windows), enabling seamless UX for gaming and social apps. This matters for retaining non-crypto-native users by abstracting transaction confirmations.

Non-custodial, MPC-based private key distribution: Arcana uses a decentralized network of nodes for Distributed Key Generation (DKG) and threshold signatures, ensuring no single entity holds a complete key. This matters for enterprise and DeFi applications requiring maximum security and regulatory compliance.

End-to-end encrypted decentralized storage layer: Arcana bundles secure, private data storage (via its own network) with its auth stack, enabling dApps to manage user data and preferences on-chain. This matters for privacy-first applications like healthcare or identity platforms that need persistent, encrypted user data.

Gas sponsorship relies on Particle's infrastructure: While user sessions are gasless, the initial gas fees are covered by Particle's centralized relayer, creating a potential point of failure and ongoing cost for the developer. This matters for protocols prioritizing maximum decentralization over UX optimization.

Primary deep integration is with Ethereum and Polygon: While multi-chain, Arcana's core security and storage modules are optimized for EVM environments, adding complexity for non-EVM chain integration compared to Particle's native SDKs. This matters for teams building primarily on Solana, Aptos, or Sui.
