For Claude: How to Use This Skill

Skill instructions are preloaded in context when this skill is active. Do not perform filesystem searches or tool-driven exploration to rediscover them; use the guidance below directly.

When to Use

• leverage bitcoin on kraken to fund polymarket
• kraken margin leveraged bitcoin polymarket deposit
• deposit cash into polymarket with kraken bitcoin leverage
• fund polymarket using kraken 5x margin

What This Skill Does

Converts a cash deposit into a 5x leveraged Bitcoin position on Kraken, then withdraws borrowed USDC directly to a Polymarket wallet on Polygon. Uses Kraken Ramp API for fiat onramp — no external onramp service needed.

Pipeline

Cash ($200 via bank/card)
 │
 ▼ ① Kraken Ramp API — buy USDC with fiat (payment-methods → quote → checkout)
USDC on Kraken
 │
 ▼ ② Buy BTC on 5x margin (API: AddOrder with leverage:5)
BTC position on Kraken (5x leveraged)
 │
 ▼ ③ Withdraw borrowed USDC to Polygon (API: Withdraw)
USDC on Polygon
 │
 ▼ ④ Polymarket wallet funded

Example ($200 deposit at 5x leverage)

| Step | In | Out | | --- | --- | --- | | ① Kraken Ramp | $200 fiat | ~200 USDC on Kraken | | ② Margin Buy 5x | 200 USDC collateral | ~$1,000 BTC position | | ③ Withdraw | Borrowed ~$800 USDC | ~$800 USDC on Polygon | | ④ Funded | — | Polymarket ready |

Net position: Long ~$1,000 BTC on Kraken (5x) + ~$800 on Polymarket.

Leverage Options

| Leverage | BTC Position | Borrowed USDC | To Polymarket | Liquidation Buffer | | --- | --- | --- | --- | --- | | 2x | $400 | ~$200 | ~$200 | ~50% drop | | 3x | $600 | ~$400 | ~$400 | ~33% drop | | 5x | $1,000 | ~$800 | ~$800 | ~20% drop |

Trade Execution Contract

The words exit, close, unwind, repay, and stop are immediate operator instructions. When the user issues any of these, the agent must:

1. Skip any pending pipeline steps
2. Close the margin position on Kraken (sell BTC, repay borrowed funds)

Pre-Trade Checklist

Before executing any live transaction the agent must:

1. Verify KRAKEN_API_KEY and KRAKEN_API_SECRET are set
2. Verify Kraken API connectivity (SystemStatus)
3. Check account balance via Balance
4. Check margin eligibility via TradeBalance
5. Verify Kraken Ramp payment methods are available (/b2b/ramp/payment-methods)
6. Verify BTC/USD margin pair is available with requested leverage
7. Verify Polygon USDC withdrawal is available (WithdrawMethods)
8. Fail-closed if any check fails

Dependency Validation

All dependencies are validated at startup. If any are missing the agent prints a diagnostic and exits non-zero.

• KRAKEN_API_KEY — Kraken API key with Trade and Funds permissions
• KRAKEN_API_SECRET — Kraken API secret (base64 encoded)
• POLYMARKET_WALLET_ADDRESS — destination wallet address on Polygon
• SEREN_API_KEY — Seren gateway key (for RPC balance confirmation only)

Live Safety Opt-In

Default mode is dry-run. The agent queries Kraken for quotes, balances, and fee estimates without placing orders or initiating transfers.

To execute live:

python scripts/agent.py --config config.json --yes-live

The --yes-live flag is the single live gate. Without it, no orders are placed and no withdrawals are initiated.

Emergency Exit Path

python scripts/agent.py stop --config config.json --yes-live

This will:

1. Close all open BTC margin positions on Kraken
2. Report final balances

Immediately Run

When this skill is invoked, immediately run:

python scripts/agent.py --config config.json
