SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @wormhole-foundation/sdk, viem, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill addresses the complexities of bridging assets and messages between different blockchain networks, enabling true cross-chain interoperability.

Core Features & Use Cases

  • Cross-Chain Messaging: Send arbitrary data between chains securely.
  • Native Token Transfers (NTT): Transfer canonical tokens across chains, preserving native asset integrity.
  • Token Bridge (Legacy): Bridge wrapped versions of existing ERC-20 tokens.
  • Cross-Chain Queries: Read data from remote chains without on-chain transactions.
  • Use Case: Transferring stablecoins from Ethereum to Arbitrum, or enabling a smart contract on Solana to trigger an action on Polygon.

Quick Start

Use the wormhole skill to send 100 DAI from Ethereum to Arbitrum.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I transfer native tokens across blockchains without creating wrapped assets?▼

You can bridge wrapped versions of existing ERC-20 tokens using the legacy token bridge functionality. This allows assets to move across networks via Wormhole's cross-chain messaging, requiring VAA verification and contract interactions to secure the transfer.

What is cross-chain messaging and how does it work for smart contracts?▼

Cross-chain queries allow you to read data from remote blockchain networks without executing on-chain transactions. This mechanism relies on Wormhole's chain ID mapping to fetch state from other chains securely and reliably for interoperability scenarios.

Do I need to understand VAA verification to perform cross-chain asset transfers?▼

You need the @wormhole-foundation/sdk and viem dependencies to facilitate cross-chain communication. These libraries provide the necessary interfaces to interact with Wormhole contracts and manage asset transfers across multiple blockchain networks.

Can I read data from a remote chain without making an on-chain transaction?▼

Cross-chain queries let you read data from remote chains without on-chain transactions. This feature is part of the Wormhole protocol's interoperability capabilities, facilitating secure and reliable data access across different blockchain networks.
