etherlink

What This Skill Does

The etherlink skill empowers OpenClaw to interact seamlessly with Etherlink, an EVM-compatible Layer 2 blockchain built on Tezos. This skill bridges the gap between natural language commands and blockchain operations, allowing you to check balances, transfer XTZ, execute smart contract calls, and retrieve on-chain data directly through the agent. By leveraging the MCP (Model Context Protocol) architecture, the skill provides a secure and standardized interface for connecting your local environment to both the Etherlink Mainnet and the Shadownet testnet, handling EVM transaction signing and RPC communication on your behalf.

Installation

To integrate this skill, ensure you have the OpenClaw environment set up. Run the following command in your terminal: clawhub install openclaw/skills/skills/efekucuk/etherlink-skill. After installation, you must configure the MCP server by adding the configuration block to your Claude or OpenClaw configuration file. Ensure you provide your EVM_PRIVATE_KEY in the environment variables, as this is required to sign transactions. Always use a secure environment and never commit your private keys to version control systems.

Use Cases

This skill is ideal for developers and power users who need to manage assets or deploy smart contracts on an L2 environment. Use it to automate balance monitoring, facilitate recurring payments in XTZ, interact with decentralized applications (dApps) by querying smart contract state, and perform rapid debugging during development on the Shadownet. It streamlines the workflow for developers who prefer conversational interfaces over manual CLI tools or heavy web explorers.

Example Prompts

1. "Check the current balance of address 0x71C7656... on the etherlink mainnet."
2. "Send 5 XTZ from my wallet to 0x123... on the etherlink-shadownet."
3. "Call the balanceOf function for contract 0xabc... to see how many tokens address 0xdef... holds on etherlink."

Tips & Limitations

Etherlink is distinct because it uses XTZ as its native currency and does not currently support EIP-1559 gas pricing. When configuring transactions, avoid setting maxFeePerGas or maxPriorityFeePerGas, as the network requires legacy gas pricing. Public RPCs are limited to 1000 requests per minute, so if you are building high-volume applications, consider running your own node. Additionally, note that bridging assets between Tezos L1 and Etherlink is handled via separate bridge protocols, which require specific Tezos tooling beyond this EVM-focused skill.
