Description
Integrate HashPack for Hedera blockchain login, transaction signing, DApp connection, and account balance retrieval in web applications.
README (SKILL.md)
HashPack Wallet Integration
Quick Start
// Detect HashPack
const hashpack = (window as any).hashpack;
// Connect
const result = await hashpack.connect();
// Get account ID
const accountId = result.accountId; // e.g., "0.0.12345"
Account ID Format
Hedera account IDs are format: 0.0.12345 (shard.realm.num)
Key Methods
// Connect (opens popup)
await hashpack.connect();
// Sign and submit transaction
const tx = new TransferTransaction()
.addHbarTransfer(from, -10)
.addHbarTransfer(to, 10);
await hashpack.signTransaction(tx);
// Get balance
const balance = await new AccountBalanceQuery()
.setAccountId(accountId)
.execute(client);
// Disconnect
hashpack.disconnect();
Environment

Usage Guidance
This skill is a coherent, client-side integration guide for the HashPack browser wallet and does not request credentials or perform installs. Before using it: (1) confirm you obtain HashPack from the official source (extension or script) — the skill metadata lacks a homepage/source, which reduces confidence; (2) test in a staging environment and review the permission prompts HashPack shows to users (wallets will ask to approve connections and signatures); (3) never hard-code private keys or requests for secrets in your app; (4) verify the listed endpoints (https://*.hashio.io) are the correct, official Hedera gateway endpoints you intend to use; (5) if you plan to allow an autonomous agent to use this skill, remember an agent that can act on behalf of a connected wallet can initiate transactions once the user has approved connections—ensure you understand when and how approvals happen. If you can provide an official source or homepage for this skill/implementation, confidence can be raised to high.
Capability Analysis
Type: OpenClaw Skill
Name: hashpack-wallet
Version: 1.0.0
The skill bundle describes the integration of the HashPack wallet for Hedera blockchain interactions, including connecting, signing transactions, and querying balances. The `SKILL.md` file provides descriptive information and TypeScript code examples for these operations. There is no evidence of prompt injection attempts against the AI agent, data exfiltration, malicious execution, persistence mechanisms, or obfuscation. While the ability to sign transactions is a powerful and sensitive capability, it aligns directly with the stated purpose of a wallet integration skill, and the skill bundle itself does not contain any instructions or code indicating malicious intent or unauthorized actions.
Capability Assessment
Purpose & Capability
Name/description (HashPack wallet integration for Hedera) matches the SKILL.md: all examples reference window.hashpack, connect/sign/disconnect, account IDs, and Hedera transaction types. No unrelated capabilities, credentials, or binaries are requested.
Instruction Scope
Runtime instructions are limited to client-side integration (window.hashpack), connecting, signing transactions, and querying balances. The instructions do not ask the agent to read arbitrary files, access unrelated environment variables, or transmit data to unexpected endpoints beyond the listed Hedera/HashPack endpoints.
Install Mechanism
Instruction-only skill with no install spec or code files, which is low risk. Note: there is no link to an official HashPack distribution or homepage in the metadata—you'll need to ensure the HashPack script/extension you include in your app is the official one.
Credentials
The skill declares no environment variables or credentials, and the instructions do not require secrets or unrelated service tokens. The listed API endpoints (mainnet/testnet/previewnet) are appropriate for Hedera/HashPack integration.
Persistence & Privilege
The skill is not always-enabled and does not request elevated persistence or system-wide changes. It does not modify other skills or agent configuration; autonomous invocation defaults are standard and not by themselves concerning here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install hashpack-wallet - After installation, invoke the skill by name or use
/hashpack-wallet - Provide required inputs per the skill's parameter spec and get structured output
