什么是 Stellar？

Stellar 技能提供了一个强大的框架，用于通过 AI 代理与 Stellar 网络进行交互。它简化了复杂的区块链任务，例如管理交易所存款的备忘录 (memo) 要求、处理最低账户储备金以及执行多操作交易。通过将其集成到 Openclaw Skills 库中，开发人员可以高精度地自动化与原生 XLM 资产以及如 USDC 等琺幣支持代币的交互。

此技能旨在处理 Stellar 共识协议 (SCP) 的技术细节，包括快速终局性和低成本操作。它确保用户遵守关键的安全实践，例如在利用联合地址和多路复用地址进行易读且高效的路由时，绝不共享私钥。

Stellar 应用场景

• 自动化向中心化交易所转移 XLM，确保包含正确的备忘录字段以防止资金损失。
• 管理账户激活和信任线储备，以便接收锚点发行的新资产。
• 利用自动化路径支付和琺幣支持的锚点促进跨境支付通道。
• 通过限价单坚控并执行去中心化交易所 (DEX) 交易。
• 将多个操作批处理到单个交易中，以实现高效的链上活动。

1. 在 Openclaw Skills 生态系统中初始化该技能，以授予代理访问 Stellar 网络协议的权限。
2. 验证目标地址，区分公钥、联合地址和多路复用格式。
3. 验证账户要求，确保维持至少 1 XLM 的余额以用于激活。
4. 为发往中心化服务的交易配置强制性备忘录字段（文本、ID 或哈希）。
5. 为 USDC 或 yXLM 等非原生资产建立必要的信任线，锁定所需的 0.5 XLM 储备金。
6. 将交易广播到网络，并坚控 3-5 秒的终局性或序列号对齐情况。

Stellar 配置指南

要将此技能集成到您的工作流中，请按照以下配置步骤操作：

# 将 Stellar 技能添加到本地环境
openclaw install stellar

# 设置您的公共网络密钥（严禁在明文中使用您的私钥）
export STELLAR_PUBLIC_KEY="G..."

# 如果使用 Soroban 智能合约，请初始化基于 Rust 的环境
stellar network add --rpc-url https://horizon.stellar.org --network-passphrase "Public Global Stellar Network ; September 2015"

Stellar 数据架构与分类体系

该技能使用以下分类法组织 Stellar 特定的数据，以确保交易准确性：

name: Stellar
description: Assist with Stellar XLM transactions, anchors, memo requirements, and cross-border payments.
metadata: {"clawdbot":{"emoji":"??","os":["linux","darwin","win32"]}}

Memo Field (Critical)

• Exchanges require memo for deposits — sending without memo loses funds
• Memo can be text, ID, or hash — use exactly what exchange provides
• Memo is NOT optional for exchanges — different from self-custody wallets
• Personal wallets don't need memo — only centralized services
• Verify memo type matches — text memo vs ID memo are different

Account Requirements

• Minimum balance: 1 XLM base reserve — required to activate account
• Each trustline adds 0.5 XLM reserve — locked, not spendable
• Sending to new account must include 1+ XLM — creates the account
• Merging account recovers reserve — must remove all trustlines first

XLM Token

• Native asset of Stellar network — used for fees and reserves
• Extremely low fees — 0.00001 XLM per operation (~$0.000001)
• Fast finality — 3-5 seconds
• No mining — Stellar Consensus Protocol (SCP)

Trustlines

• Must trust an issuer before receiving their tokens — explicit opt-in
• Trustline costs 0.5 XLM reserve — locked until removed
• Remove trustlines to recover reserve — must have zero balance first
• Scam tokens can't be forced on you — trustlines required

Anchors and Assets

• Anchors issue fiat-backed tokens — USDC, yXLM (yield), various fiats
• Stellar has native USDC — issued by Circle directly
• Verify anchor reputation — not all are trustworthy
• Path payments convert automatically — send USD, receive EUR

Addresses

• Public keys start with "G" — 56 characters
• Secret keys start with "S" — never share
• Federated addresses: user*domain.com — human-readable, resolves to G address
• Muxed addresses encode account + memo — M prefix, newer format

Transaction Features

• Multiple operations per transaction — batch actions
• Sequence number like Ethereum nonce — must be sequential
• Time bounds optional — transactions can expire
• Fee bumping available — increase fee on pending transaction

DEX and Trading

• Built-in decentralized exchange — native to protocol
• Order book model — limit orders, not AMM
• Path payments find best route — automatic conversion
• Swap aggregators exist — StellarX, Lobstr markets

Wallets

• Lobstr — most popular, mobile and web
• StellarTerm — web-based trading
• Solar Wallet — Keybase team, desktop
• Ledger support — hardware wallet via compatible apps
• Freighter — browser extension for dApps

Common Issues

• "Destination account does not exist" — account not created, needs 1+ XLM
• "Missing memo" — exchange requires memo, transaction may be lost
• "Insufficient balance" — must keep minimum reserve
• "Trustline not established" — must add trustline before receiving token
• Transaction stuck — rare on Stellar, usually instant

Cross-Border Payments

• Designed for remittances — fast and cheap
• Anchor network for fiat on/off ramps — varies by country
• MoneyGram partnership — cash pickup locations
• USDC corridors — stablecoin transfers between countries

Soroban (Smart Contracts)

• Smart contract platform on Stellar — newer addition
• Different from traditional Stellar operations — Rust-based contracts
• Expanding Stellar capabilities — DeFi, NFTs becoming possible
• Still maturing — ecosystem growing

Security

• Seed phrase standard — 24 words
• Multisig available — require multiple signatures
• Sep-10 authentication — standard for web auth
• Verify transaction details — XDR can be decoded before signing
