Setup snapshot

git clone https://github.com/aite550659-max/hedera-dev-skill.git
  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Hedera Development Skill

About Hedera (context for development)

Hedera is a public DLT network using hashgraph consensus (not blockchain):

  • aBFT security: Asynchronous Byzantine Fault Tolerant (strongest form)
  • Finality <3 seconds: Transactions cannot be reversed once finalized
  • Fixed USD fees: Starting at $0.0001 per transaction
  • EVM compatible: Supports Solidity, works with Ethereum tools
  • Carbon negative: More efficient than Visa transactions
  • Hedera Council: Governed by 30+ leading enterprises (Google, IBM, Dell, LG, Deutsche Telekom, ServiceNow, Chainlink Labs, etc.)

Key insight: "Hashgraph uses gossip protocol + virtual voting for consensus. No miners, no wasted work, 100% efficient."

What this Skill is for

Use this Skill when the user asks for:

  • Hedera dApp UI work (React / Next.js)
  • Wallet connection with HashConnect or WalletConnect
  • HBAR transfers and account management
  • Hedera Token Service (HTS) - fungible and NFT tokens
  • Hedera Consensus Service (HCS) - timestamped, ordered messages
  • AI trust and attestation - Audit trails for AI accountability
  • Autonomous agent logging - Verifiable AI decision records (see OpenClaw/moltbot integration)
  • Smart contract deployment and interaction (Solidity)
  • Mirror node queries and indexing
  • Hedera JSON-RPC Relay for EVM tooling compatibility

OpenClaw (Moltbot) Integration

This skill includes patterns for integrating OpenClaw AI agents with Hedera:

  • Attestation of agent actions to HCS for "Trust but Verify"
  • Immutable audit trails of AI decisions and transactions
  • Hash-chained logs for tamper-evident accountability
  • See ai-trust-attestation.md for implementation details

Default stack decisions (opinionated)

  1. SDK: @hashgraph/sdk first

    • Use official Hedera SDK for all native Hedera services
    • TypeScript/JavaScript: @hashgraph/sdk
    • Supports: accounts, tokens, consensus, files, smart contracts, scheduled transactions
  2. Wallet: HashConnect for Hedera-native

    • HashConnect for HashPack and other Hedera wallets
    • WalletConnect for broader ecosystem support
    • Always support both when building consumer dApps
  3. Smart Contracts: Solidity via Hedera EVM

    • Deploy Solidity contracts using ContractCreateTransaction
    • Or use JSON-RPC Relay with standard EVM tools (Hardhat, Foundry)
    • Precompiles available for HTS integration from Solidity
  4. Tokens: HTS over custom contracts

    • Prefer Hedera Token Service for fungible/NFT tokens
    • Native performance, lower fees, built-in compliance features
    • Use HTS precompiles when interacting from smart contracts
  5. Data: Mirror nodes for queries

    • Use mirror nodes for historical data, account balances, transaction history
    • REST API: https://mainnet.mirrornode.hedera.com/api/v1/
    • Never query consensus nodes for historical data
  6. Testing

    • Testnet: Use Hedera testnet (free HBAR from faucet)
    • Local: Hedera Local Node for isolated development
    • Previewnet: For testing new network features

Operating procedure (how to execute tasks)

1. Classify the task layer

  • UI/wallet layer (HashConnect, React hooks)
  • SDK/scripts layer (transactions, queries)
  • Token layer (HTS fungible, NFT, custom fees)
  • Consensus layer (HCS topics, messages)
  • Smart contract layer (Solidity, precompiles)
  • Data layer (mirror node REST, GraphQL)

2. Pick the right building blocks

  • Native Hedera operations: @hashgraph/sdk
  • EVM tooling compatibility: JSON-RPC Relay + ethers.js/viem
  • Wallet UX: HashConnect (@hashconnect/react)
  • Data queries: Mirror node REST API
  • Real-time data: Mirror node gRPC/websocket

3. Implement with Hedera-specific correctness

Always be explicit about:

  • Network (mainnet/testnet/previewnet/local)
  • Operator account ID and private key handling
  • Transaction fees and max transaction fee settings
  • Account auto-association slots for tokens
  • Key structures (single key, threshold, key list)
  • Memo fields for compliance/tracking

4. Add tests

  • Unit tests: Mock SDK client responses
  • Integration tests: Hedera testnet or local node
  • For wallet UX: Test with HashPack on testnet

5. Deliverables expectations

When you implement changes, provide:

  • Exact files changed + diffs
  • Commands to install/build/test
  • Network configuration (testnet vs mainnet)
  • Risk notes for anything touching keys/fees/token transfers
