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

npm i -g @myriadmarkets/cli

Setup

# 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

# 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

# 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.

Wallet Management with MoonPay

Myriad trades on BNB Chain and settles in USDT. Use MoonPay to create a BNB Chain wallet, fund it, and export the key for Myriad.

npm install -g @moonpay/cli
mp login

# Create a dedicated trading wallet
mp wallet create --name "myriad-agent"
mp wallet retrieve --wallet "myriad-agent"   # note your BNB Chain address

Fund with USDT on BNB Chain

# Buy USDT directly on BNB Chain
mp buy --token usdt_bsc --amount 100 --wallet <bnb-address> --email <email>

# Or bridge USDT from another chain
mp token bridge \
  --from-wallet myriad-agent --from-chain ethereum \
  --from-token 0xdac17f958d2ee523a2206206994597c13d831ec7 \
  --from-amount 100 \
  --to-chain bsc \
  --to-token 0x55d398326f99059ff775485246999027b3197955

Export Key for Myriad

# ⚠️ Your private key gives full access to your wallet.
# Never share it, commit it to version control, or reuse it across services.
mp wallet export --wallet "myriad-agent"
# Copy EVM private key → use in myriad wallet setup or MYRIAD_PRIVATE_KEY

Check Balance

mp token balance list --wallet <bnb-address> --chain bsc

Withdraw Winnings to Bank

mp virtual-account offramp create \
  --name "Offramp" \
  --bankAccountId <bank-account-id> \
  --stablecoin usdc \
  --chain bsc

End-to-End Workflow

1. npm i -g @myriadmarkets/cli
2. mp wallet create --name "myriad-agent"
3. mp buy --token usdt_bsc --amount 100 --wallet <address> --email <email>
4. mp wallet export --wallet "myriad-agent" → copy private key
5. myriad wallet setup → paste key (stored encrypted)
6. myriad markets list --state open --order volume --sort desc
7. myriad trade buy --market-id <id> --outcome-id <id> --value 25 --dry-run
8. myriad trade buy --market-id <id> --outcome-id <id> --value 25
