Our review

Fetches details of an EVM transaction by its hash and optionally the chain.

Strengths

  • Supports multiple EVM chains (Ethereum, Polygon, Arbitrum, etc.)
  • Uses public nodes as fallback
  • Quick retrieval of basic transaction info

Limitations

  • Requires the `cast` tool to be installed
  • Only works for EVM chains
  • Does not show detailed logs or internal calls
When to use it

When you have a transaction hash on an EVM chain and want to quickly check its status, value, or input data.

When not to use it

For non-EVM chains (e.g., Solana) or when you need in-depth event analysis or transaction tracing.

Security analysis

Safe
Quality score88/100

The skill only reads public blockchain data via a Bash script using the `cast` tool or explorer APIs. No destructive commands, no exfiltration of secrets, no obfuscated payloads, and no risky operations like `curl|sh` or `rm -rf`. The transaction hash input is expected to be a hex string, and the script likely validates it. The skill does not write files or require elevated privileges.

Examples

Ethereum transaction details
Show me details for transaction 0x1234abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890 on Ethereum
Polygon transaction details
Look up transaction 0x5678abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890 on Polygon

name: evm-tx-info description: Use this skill when the user asks for "transaction details", "show me tx", "what happened in this transaction", "look up transaction", or mentions viewing transaction data on EVM chains (Ethereum, Polygon, Arbitrum, etc.). Requires a transaction hash and optional chain parameter. allowed-tools: Bash

EVM Transaction Info Fetcher

Gets transaction details by hash from an EVM blockchain network.

Usage

Run the script with transaction hash and optional chain:

${CLAUDE_PLUGIN_ROOT}/scripts/crypto-evm-tx-info.sh <tx_hash> [chain]

Arguments

  • tx_hash (required): Transaction hash (0x + 64 hex characters)
  • chain (optional): Chain name - ethereum (default), polygon, arbitrum, optimism, base, bsc

Supported Chains

| Chain | Aliases | Explorer | |-------|---------|----------| | ethereum | eth, mainnet | Etherscan | | polygon | matic | Polygonscan | | arbitrum | arb | Arbiscan | | optimism | op | Optimism Etherscan | | base | - | Basescan | | bsc | binance | BSCScan |

Requirements

  • cast (Foundry) must be installed
  • RPC URL is optional (uses PublicNode fallback)

Examples

# Get transaction on Ethereum
${CLAUDE_PLUGIN_ROOT}/scripts/crypto-evm-tx-info.sh 0x1234...abcd

# Get transaction on Polygon
${CLAUDE_PLUGIN_ROOT}/scripts/crypto-evm-tx-info.sh 0x5678...efgh polygon

Note

For Solana transaction info, use the sol-tx-info skill instead.
