description	Execute Myriad AMM `trade buy` and `trade sell` flows safely with preflight checks, dry-run quoting, allowance strategy, and BNB-chain stablecoin auto-swap awareness.

Myriad Trade Execution

Overview

Use this skill to convert an AMM trade intent into a safe, executable command sequence. Enforce preflight checks before signing transactions.

This skill does not own myriad ob ... workflows. For order book discovery, depth inspection, limit orders, market orders, or position management, hand off to $myriad-orderbook.

Preflight Checklist

Run this checklist before any write action.

1. Validate wallet accessibility.

• Confirm the signer exists via configured wallet, --private-key, or MYRIAD_PRIVATE_KEY.
• If missing, route to $myriad-wallet-ops.

2. Validate balances.

• Run myriad wallet balances --json.
• Confirm native gas token balance and relevant collateral/stable token balances.

3. Validate market target.

• Resolve market with myriad markets show when the identifier is uncertain.
• Ensure only one selector is used: --market-id or --market-slug.

4. Validate execution parameters.

• Use explicit --slippage when user gives risk constraints.
• Start with --dry-run for first pass.

Buy Workflow

1. Quote first.

myriad trade buy --market-id 164 --outcome-id 0 --value 25 --dry-run --json

2. Configure allowances deliberately.

• Per-action approval: --allowance <amount|UNLIMITED>.
• Auto-swap approval: --swap-allowance <amount|UNLIMITED>.
• Global override: root --allowance or MYRIAD_ALLOWANCE.

3. Decide auto-swap behavior.

• On BNB Chain, when spend token is USDT/USD1 and balance is insufficient, auto-swap may use PancakeSwap.
• Disable with --no-auto-swap when strict no-swap behavior is required.

4. Execute only after quote review.

myriad trade buy --market-id 164 --outcome-id 0 --value 25 --slippage 0.05 --json

Sell Workflow

Use either target value or shares.

myriad trade sell --market-id 164 --outcome-id 0 --value 15 --dry-run --json

myriad trade sell --market-id 164 --outcome-id 0 --shares 20 --json

Failure Handling

• Network mismatch error: Align runtime --chain-id and deployment addresses with market network.
• Missing signer error: Run myriad wallet setup or pass --private-key for one-off execution.
• Approval-related failure: Increase --allowance / --swap-allowance or use UNLIMITED with explicit user intent.
• Slippage failure: Re-quote, then adjust --slippage conservatively.

Boundaries

• Do not use this skill for myriad ob ...; hand off to $myriad-orderbook.
• Do not run claim flows here; hand off to $myriad-claims.
• Do not define MCP server orchestration here; hand off to $myriad-mcp-orchestration.
