Goat 🐐

Goat 🐐 (Great Onchain Agent Toolkit) is an open-source framework for connecting AI agents to any onchain app.

Problem:

Today, there are thousands of agents, built across 5+ frameworks (Langchain, Vercel's AI SDK, Eliza, etc) using multiple languages (TypeScript, Python).

These agents can connect to various wallets, but programming even a simple onchain action (sending tokens, using a DeFi protocol) requires rebuilding support for each combination of framework, language, and wallet provider.

Solution:

Goat solves this by providing an open-source, provider-agnostic framework that abstracts away all these combinations.

Write an onchain action once, and it works across all frameworks, wallets, and languages, supporting both Solana and EVM chains.

Key features

1. Works Everywhere: Compatible with Langchain, Vercel’s AI SDK, Eliza, and more.
2. Wallet Agnostic: Supports all wallets, from key pairs to Crossmint and Coinbase.
3. Multi-Chain: Supports EVM chains and Solana (more coming 👀).
4. Customizable: Use or build plugins for any protocol (Polymarket, Uniswap, etc).

How it works

Goat plugs into your agents tool calling capabilities adding all the functions your agent needs to interact with blockchain protocols.

High-level, here's how it works:

Configure the wallet you want to use

// ... Code to connect your wallet (e.g createWalletClient from viem)
const wallet = ...

const tools = getOnChainTools({
  wallet: viem(wallet),
})

Add the plugins you need to interact with the protocols you want

const wallet = ...

const tools = getOnChainTools({
  wallet: viem(wallet),
  plugins: [
    sendETH(),
    erc20({ tokens: [USDC, PEPE] }),
    faucet(),
    polymarket(),
    // ...
  ],
})

Connect it to your agent framework of choice

// ... Code to connect your wallet (e.g createWalletClient from viem)
const wallet = ...

const tools = getOnChainTools({
  wallet: viem(wallet),
  plugins: [ 
    sendETH(),
    erc20({ tokens: [USDC, PEPE] }), 
    faucet(), 
    polymarket(), 
    // ...
  ],
})

// Vercel's AI SDK
const result = await generateText({
    model: openai("gpt-4o-mini"),
    tools: tools,
    maxSteps: 5,
    prompt: "Send 420 ETH to ohmygoat.eth",
});
