Claude Plugins

Three plugins for Claude Code that add crypto trading, development tools, and Web3 SDK capabilities directly into your Claude Code sessions. Each plugin is purpose-built for a specific workflow — install one, two, or all three depending on what you need.

Installation

Add the plugin marketplace

Register the Bankr plugin repository so Claude Code knows where to find the plugins:
Add marketplace
```
claude plugin marketplace add BankrBot/claude-plugins
```

Install the plugin(s) you need

Pick the plugins that match your workflow. You can install any combination of the three:

# Trading & Polymarket
claude plugin install bankr-agent@bankr-claude-plugins

# Dev toolkit
claude plugin install bankr-agent-dev@bankr-claude-plugins

# Web3 SDK with x402 payments
claude plugin install bankr-x402-sdk-dev@bankr-claude-plugins

The Three Plugins

bankr-agent

Crypto trading, Polymarket predictions, and portfolio management. This is the main plugin for interacting with Bankr’s trading capabilities through Claude Code. Use it to buy and sell tokens, place Polymarket bets, check balances, view your portfolio, and execute any action your Bankr agent supports — all through natural language in your Claude Code session. Requires a Bankr API key (bk_...).

bankr-agent-dev

Developer toolkit for building on top of Bankr. Provides scaffolding, API documentation, TypeScript interfaces, and working code examples directly inside Claude Code. Use it when you are building integrations, writing bots, or need quick reference to Bankr endpoints and data structures. It gives Claude Code deep context about the Bankr API so it can generate accurate, working code for you.

bankr-x402-sdk-dev

Web3 SDK integration powered by x402 micropayments. Gives Claude Code the ability to perform market analysis, portfolio tracking, token swaps, NFT operations, and leveraged trading — all paid per request at $0.10 USDC on Base. No API key needed. This plugin is ideal for developers who want to build SDK-first integrations or prefer the x402 payment model over API key authentication.

Usage

Once installed, you do not need to do anything special. Just use Claude Code normally. Ask about crypto prices, request trades, query your portfolio, or ask Claude to write Bankr integration code. The plugins inject the relevant Bankr context and capabilities automatically — Claude Code will know when and how to use them.

Examples of what you can ask:

“What is the price of ETH on Base?”
“Buy $50 of PEPE on Base”
“Show my portfolio across all chains”
“What are the top Polymarket markets right now?”
“Scaffold a TypeScript bot that buys trending tokens”
“Write a script that uses the Bankr SDK to track my portfolio”

The plugins handle routing your request to the correct Bankr backend (Agent API or x402 SDK) depending on which plugins you have installed and what the request requires.

Which Plugin Should You Install?

Use Case	Plugin
Trading, swaps, portfolio management	`bankr-agent`
Polymarket predictions and bets	`bankr-agent`
Building bots or integrations	`bankr-agent-dev`
API reference and code generation	`bankr-agent-dev`
SDK-first development with x402	`bankr-x402-sdk-dev`
Market analysis and NFT operations	`bankr-x402-sdk-dev`

If you are not sure, start with bankr-agent for trading and bankr-agent-dev for development. Add bankr-x402-sdk-dev if you want to build with the x402 payment model.
