OpenClaw 评估
The instructions match a Hedera transaction builder, but the skill fails to declare or explain how private keys/operator credentials are provided and recommends installing an SDK without an install spec — this mismatch could lead to accidental key exposure or unclear runtime behavior.
目的
The skill's stated purpose (build, sign, submit Hedera transactions) aligns with the SDK usage shown, but the registry metadata declares no required credentials or config while the instructions implicitly require access to a signing key (operatorKey or a wallet like HashPack). Requiring no credentials is not coherent with a transaction-signing tool.
说明范围
SKILL.md instructs installing @hashgraph/sdk and shows code that signs transactions with an operator key or HashPack, but it does not specify how keys are loaded (env vars, key files, wallet flow). Because it omits safe key-handling guidance, users might be prompted to paste private keys or expose credentials to the agent — the instructions are incomplete and risk-prone.
安装机制
There is no formal install spec in the skill bundle; SKILL.md tells the user to run `npm install @hashgraph/sdk`. Installing the official npm package is expected for this purpose, but the absence of an install specification in the registry (and no pinned version or integrity guidance) reduces clarity and reproducibility.
证书
The skill declares no required environment variables or primary credential even though signing and submitting transactions requires private keys or a wallet connection. This under-declaration is disproportionate and increases the chance of insecure key handling. The listed network endpoints are external but expected for Hedera.
持久
The skill does not request always:true and does not ask to modify other skills or system-wide settings. It appears not to require persistent elevated privileges.

# Hedera Transaction Builder
## Setup
```bash
npm install @hashgraph/sdk
```
## Client Setup
```typescript
import { Client, AccountBalanceQuery, Hbar } from '@hashgraph/sdk';
const client = Client.forMainnet();
// Or for testnet:
const client = Client.forTestnet();
```
## Transfer HBAR
```typescript
import { TransferTransaction, Hbar } from '@hashgraph/sdk';
const tx = new TransferTransaction()
.addHbarTransfer(fromAccountId, new Hbar(-100)) // send
.addHbarTransfer(toAccountId, new Hbar(100)) // receive
.setTransactionMemo("Payment for goods");
// Sign with hashpack or operator
const signTx = await tx.sign(operatorKey);
const result = await signTx.execute(client);
```
## Key Transaction Types
### AccountCreate
```typescript
new AccountCreateTransaction()
.setKey(publicKey)
.setInitialBalance(new Hbar(10))
.setAccountMemo("My account");
```
### TokenAssociate
```typescript
new TokenAssociateTransaction()
.setAccountId(accountId)
.setTokenIds([tokenId1, tokenId2]);
```
### TopicMessage
```typescript
new TopicMessageTransaction()
.setTopicId(topicId)
.setMessage("Hello Hedera!");
```
## Network Endpoints
- **Mainnet**: `https://mainnet.hashio.io/api`
- **Testnet**: `https://testnet.hashio.io/api`
## Important Concepts
- **Hbar**: 1 HBAR = 100,000,000 tinybars
- **Account ID**: Format `shard.realm.num` (e.g., `0.0.12345`)
- **Transaction Fee**: Small HBAR fee for each transaction
- **Transaction Valid Duration**: 180 seconds by default
