# Myriad — AI Prediction Market Trading Agent

## Overview

Myriad CLI gives AI agents a full trading loop on Myriad prediction markets running on BNB Chain: discover markets, make decisions, execute trades, and claim winnings. Supports MCP server mode for multi-agent orchestration.

**Chain:** BNB Chain (chainId=56)
**Settlement token:** USDT / USD1
**Default slippage:** 0.05 (trades), 0.005 (swaps)

## Installation

```bash
npm i -g @myriadmarkets/cli
```

## Setup

```bash
# 1. Create and fund a MoonPay wallet (see Wallet section below)
# 2. Configure Myriad with your private key
myriad wallet setup        # interactive — encrypts key to file + OS keychain
# OR
export MYRIAD_PRIVATE_KEY="0x..."   # env var

# 3. Deposit funds
myriad wallet deposit
```

Config resolves in order: CLI flags → env vars / `.env` → `~/.config/myriad/config.json` → built-in defaults.

## Key Commands

### Markets

```bash
# List open markets sorted by volume
myriad markets list --state open --order volume --sort desc

# Filter by keyword
myriad markets list --keyword "bitcoin" --state open --limit 10

# JSON output for agent pipelines
myriad markets list --state open --json
```

### Trading

```bash
# Buy a position (dry-run first)
myriad trade buy --market-id 164 --outcome-id 0 --value 25 --dry-run
myriad trade buy --market-id 164 --outcome-id 0 --value 25

# Sell a position
myriad trade sell --market-id 164 --outcome-id 0 --value 25 --dry-run
myriad trade sell --market-id 164 --outcome-id 0 --value 25
```

**Always use `--dry-run` before write operations** — preview the transaction without execution.

### Portfolio & Wallet

```bash
# View open positions and exposure
myriad portfolio

# Check balances
myriad wallet balances

# Swap tokens (auto-runs when USDT balance is insufficient)
myriad swap
```

### Claims

```bash
# Sweep all resolved winning positions
myriad claim all
```

### MCP Server

```bash
# Run as MCP server for Claude Code / multi-agent orchestration
myriad mcp
```

MCP config for Claude Code (`~/.claude/settings.json`):

```json
{
  "mcpServers": {
    "myriad": {
      "command": "myriad",
      "args": ["mcp"]
    }
  }
}
```

### Skills (Claude / OpenClaw)

```bash
# Install Myriad skills into Claude Code
myriad skills install --target claude
```

## Agent Patterns

### Event-Driven Trader
Spot a news catalyst → scan markets → stage trade:

```bash
myriad markets list --keyword "fed rate" --state open --json
# → review markets and odds
myriad trade buy --market-id <id> --outcome-id <id> --value 50 --dry-run
# → confirm looks right
myriad trade buy --market-id <id> --outcome-id <id> --value 50
```

### Portfolio Monitor
Check exposure before each trading cycle:

```bash
myriad portfolio
myriad wallet balances
```

### Winnings Sweeper
Automate claims on resolved markets:

```bash
myriad claim all
```

### Multi-Agent Desk
Run scout + execution agents via MCP:

```bash
myriad mcp   # Claude Code connects via MCP tools
```
