# Agent Skills WDK provides agent skills: structured instruction sets that teach AI agents how to create wallets, send transactions, swap tokens, bridge assets, and interact with DeFi protocols across 20+ blockchains. All operations are self-custodial. Keys stay on your machine, with no third-party custody dependency. {% hint style="info" %} **Skill vs MCP Toolkit**: Use an **agent skill** when your agent platform works with file-based instructions (e.g., OpenClaw, Cursor). Use the [MCP Toolkit](https://docs.wdk.tether.io/ai/mcp-toolkit) when your agent supports the Model Context Protocol natively (e.g., Claude, Cursor). Use both for maximum coverage. {% endhint %} ## What Are Agent Skills? An agent skill is a structured set of instructions and reference documentation that teaches an AI agent to use a specific tool or SDK. Skills follow the [AgentSkills specification](https://agentskills.io/specification). Each skill is a `SKILL.md` file with frontmatter metadata and detailed instructions that any compatible agent can load and execute. WDK publishes a skill that covers the full SDK surface: wallet modules, swap, bridge, lending, fiat on/off-ramps, and the indexer. When an agent loads the skill, it learns WDK's APIs so you don't need blockchain expertise to get started. You can view the full skill file on [GitHub](https://github.com/tetherto/wdk-docs/blob/main/skills/wdk/SKILL.md). ## Capabilities Once an agent loads the WDK skill, it can: | Category | Operations | | ---------------- | ------------------------------------------------------------------------------------------------------------------ | | **Wallets** | Create and recover wallets across EVM chains, Bitcoin, Solana, Spark, TON, and Tron | | **Transactions** | Send native tokens and token transfers (ERC-20, SPL, Jetton, TRC-20) | | **Swaps** | DEX swaps via Velora (EVM) and StonFi (TON) | | **Bridges** | Cross-chain bridges with USDT0 via LayerZero | | **Lending** | Supply, borrow, repay, and withdraw via Aave V3 | | **Fiat** | Buy and sell crypto via MoonPay on/off-ramps | | **Gasless** | Fee-free transfers on TON (via paymaster) and Tron (via gas-free service), and ERC-4337 account abstraction on EVM | {% hint style="warning" %} All write operations require explicit human confirmation. The skill instructs agents to estimate fees before sending and includes prompt injection protection guidance. {% endhint %} ## How It Works 1. **Install the skill** by running `npx skills add tetherto/wdk-agent-skills` and selecting the agent you prefer 2. **Agent loads the skill** and reads `SKILL.md` along with per-module reference files to learn WDK's API surface 3. **Agent executes operations** when you ask it to create a wallet or send a transaction, generating the correct WDK code 4. **You confirm** before any write operation (transactions, swaps, bridges) goes through The skill includes security guidance: pre-transaction validation checklists, prompt injection detection rules, and mandatory key cleanup patterns. ## Self-Custodial vs Hosted WDK's agent skills use a self-custodial model where your agent controls its own keys locally. This differs from hosted solutions where a third party manages your keys. | Feature | WDK | Coinbase Agentic Wallet | Privy Server Wallets | | ---------------- | -------------------------------------------------------------- | ----------------------------- | ----------------------------- | | Custody model | Self-custodial | Coinbase-hosted | Privy-hosted (server) | | Multi-chain | Yes (EVM, Bitcoin, Solana, TON, Tron, Spark + more) | EVM + Solana | EVM + Solana + Bitcoin + more | | Open source | Yes (SDK + skills) | CLI/skills open, infra closed | Skills open, API closed | | MCP support | Yes ([MCP Toolkit](https://docs.wdk.tether.io/ai/mcp-toolkit)) | Via skills | Via skills | | OpenClaw support | Yes (`npx skills add tetherto/wdk-agent-skills`) | Yes (npx skills) | Yes (ClawHub skill) | | x402 payments | Via [community extensions](#community-projects) | Yes (native) | No | | Key management | Local / self-managed | Coinbase infrastructure | Privy infrastructure | ## Use With Agent Platforms | Platform | How to Use | | ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | **OpenClaw** | Run `npx skills add tetherto/wdk-agent-skills` and select your agent.
