Crypto & On-Chain Trader

This is a template.
The default signal is keyword-based market discovery combined with conviction-based sizing and onchain_bias() — three stacked structural edges, no external API required.
The skill handles all the plumbing (market discovery, trade execution, safeguards). Your agent provides the alpha.

Strategy Overview

Crypto markets have the most sophisticated on-chain data infrastructure of any asset class — and Polymarket's retail participants almost never use it. This skill exploits three documented structural edges without any API calls:

1. 1. Instrument type confidence — ETF flow data is published daily by Farside/CoinGlass before Polymarket retail reprices. Protocol upgrade dates are posted on GitHub weeks ahead. Retail prices these as uncertain when they aren't.
2. BTC halving cycle phase — the halving date is mathematically predictable. The post-halving price cycle (consolidation → bull → distribution → bear) is historically documented. BTC price milestone markets get conviction adjusted by current cycle position.
3. Asian regulatory session timing — crypto regulatory news from Korea, Japan, and China breaks during Asian business hours. Polymarket is US-dominated — repricing lags 15–30 minutes.

Signal Logic

Default Signal: Conviction-Based Sizing with On-Chain Bias

1. 1. Discover active crypto markets on Polymarket
2. Compute base conviction from distance to threshold (0% at boundary → 100% at p=0/p=1)
3. Apply onchain_bias() — three stacked layers: instrument confidence × BTC cycle phase × timing
4. Size = max(MIN_TRADE, conviction × bias × MAX_POSITION) — capped at MAXPOSITION
5. Skip markets with spread > MAXSPREAD or fewer than MIN_DAYS to resolution

On-Chain Bias (built-in, no API required)

Layer 1 — Instrument Type Confidence

Instrument type	Multiplier	Why
Spot ETF inflows (BlackRock, Fidelity)	1.30x	Daily flow data (Farside/CoinGlass) published before Polymarket reprices — biggest info gap in crypto
BTC halving event markets

1.25x | Halving date is mathematically predictable (~210,000 blocks) — retail misprices near-certain events |
| Protocol upgrade / hard fork dates | 1.20x | Ethereum EIP / Solana upgrade timelines on GitHub and core dev calls — public weeks ahead |
| DeFi TVL / protocol milestones | 1.10x | DeFiLlama tracks TVL in real-time — "will protocol reach $X TVL" markets lag published data |
| BTC price milestones | 1.10x × cycle | Halving cycle multiplier applied on top (see Layer 2) |
| ETH / SOL / general ATH milestones | 1.10x | On-chain data gives partial directional edge |
| Stablecoin / crypto regulation | 1.05x | Regulatory calendar partially predictable |
| NFT / Ordinals milestones | 0.75x | Narrative-driven — no on-chain predictive signal |
| Memecoin / altcoin hype | 0.70x | Pure retail sentiment — zero predictive signal, trade very small |

Layer 2 — BTC Halving Cycle Phase (BTC price markets only)

The Bitcoin halving (every ~210,000 blocks, ~4 years) creates a historically documented price cycle. For BTC price milestone markets, the base type confidence is multiplied by the current cycle phase:

Phase	Days post-halving	Multiplier	Historical pattern
Early consolidation	0–180	×1.05	Miners sell, market absorbs supply shock
Bull phase

181–540 | ×1.20 | Historically strongest 12-month returns |
| Distribution | 541–900 | ×1.00 | Price peaks, direction uncertain |
| Bear phase | 901+ | ×0.85 | Fade bullish BTC price targets |

Last halving: April 19, 2024 (block 840,000). Next: ~April 2028. The skill prints btc_cycle_day=N on startup so you always know where you are.

Layer 3 — Asian Session Timing

Crypto regulatory news from South Korea, Japan, and China breaks during Asian business hours. Polymarket is US-dominated:

Condition	Multiplier
Regulatory/ban/approval question + 01:00–09:00 UTC	1.15x — US retail asleep, repricing lag
Regulatory/ban/approval question + 13:00–21:00 UTC

0.95x — US prime time, priced within minutes |

Combined and capped at 1.40x. An ETF inflow market in Asian hours → 1.30 × 1.15 = 1.40x cap. A memecoin question at any time → 0.70x — position sized near MIN_TRADE floor.

Remix Signal Ideas

• - Farside BTC ETF flows: Replace market.current_probability with daily net flow implied probability — trade the divergence between institutional flow data and Polymarket retail pricing directly
• Glassnode free tier: SOPR, NUPL, exchange inflow/outflow — feed into p to trade on-chain sentiment vs market price
• CoinGlass funding rates: Extreme positive funding = leveraged longs = squeeze risk → fade YES on price targets; extreme negative → fade NO
• DeFiLlama API: Real-time TVL for any protocol — compare to market-priced threshold for TVL milestone markets

Safety & Execution Mode

The skill defaults to paper trading (venue="sim"). Real trades only with --live flag.

Scenario	Mode	Financial risk
INLINECODE8	Paper (sim)	None
Cron / automaton

Paper (sim) | None |
| python trader.py --live | Live (polymarket) | Real USDC |

INLINECODE10 and cron: null — nothing runs automatically until you configure it in Simmer UI.

Required Credentials

Variable	Required	Notes
INLINECODE12	Yes	Trading authority. Treat as high-value credential.

Tunables (Risk Parameters)

All declared as tunables in clawhub.json and adjustable from the Simmer UI.

Variable	Default	Purpose
INLINECODE15	INLINECODE16	Max USDC per trade (reached at 100% conviction)
INLINECODE17

15000 | Min market volume filter (USD) — crypto needs liquidity |
| SIMMER_MAX_SPREAD | 0.06 | Max bid-ask spread (6%) — tighter than other traders |
| SIMMER_MIN_DAYS | 3 | Min days until resolution — crypto moves faster |
| SIMMER_MAX_POSITIONS | 8 | Max concurrent open positions |
| SIMMER_YES_THRESHOLD | 0.38 | Buy YES if market price ≤ this value |
| SIMMER_NO_THRESHOLD | 0.62 | Sell NO if market price ≥ this value |
| SIMMER_MIN_TRADE | 5 | Floor for any trade (min USDC regardless of conviction) |
