The Best Crypto and Trading Skills for Claude Code

2026-10-17

Crypto skills are the most dangerous category in the directory. They combine live money, irreversible transactions, and APIs whose failure modes are silent.

Our finance category has 76 skills, and the crypto subset is where the technical detail is densest. These seven score above 8.6 and cover the main primitives: execution, market data, and prediction markets.

Execution

dex-execution — 9.3 · Finance & Trading

Solana DEX swaps via the Jupiter aggregator: quoting, transaction construction, and submission. The highest-scoring skill in the group. What makes it credible is that it handles the full path including quote comparison — the part where naive implementations lose money to slippage.

Market data

defillama-api — 9.0 · Finance & Trading

DeFi analytics across chains: TVL, token prices, DEX volumes, and fees. Free and no-auth, which matters for reliability — API keys expire and rate limits bite.

dexscreener-api — 9.0 · Finance & Trading

Multi-chain DEX pair data — prices, volume, liquidity, transactions — with no authentication. The practical choice for pair-level data.

dex-pool-analysis — 8.8 · Finance & Trading

AMM pool mechanics across Raydium, Orca, and Meteora, including fee structures. Useful before providing liquidity rather than after.

Prediction markets

kalshi-api — 9.1 · Finance & Trading

Kalshi exchange mechanics: RSA-PSS authentication, order schema, and YES/NO orderbook conversion. Kalshi's API has enough specific conventions that a generic HTTP skill will produce wrong orders.

kalshi-weather-markets — 8.8 · Finance & Trading

Weather contracts — daily temperature brackets and thresholds.

kalshi-crypto-index-markets — 8.6 · Finance & Trading

Crypto price range markets, daily and hourly.

These skills can move real money. Three specific risks:

  1. Irreversible transactions. A wrong swap does not have an undo. Any execution skill should be run with small amounts first, and with a human reviewing the transaction before signing.
  2. Authentication scope. kalshi-api uses RSA-PSS keys with trading permissions. Store them the way you would store a private key.
  3. Silent failure. Market data APIs can return stale or partial data without an error. A strategy built on a stale quote will trade wrong and look fine.

    4. We score security conservatively, but a high score is not authorization. The capability manifest — what the skill reads, signs, and sends — is the thing to check, and for keys specifically, you should read the scripts yourself.

    How to choose

    • Solana swaps? dex-execution.
    • Kalshi? kalshi-api plus the specific market skill.
    • DeFi analytics? defillama-api and dexscreener-api.
    • Liquidity provision? dex-pool-analysis first.
