Automated summary

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.

How this analysis is made

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

Name: EVM Transaction Info Fetcher
Author: Skills Guide Bot

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.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/evm-transaction-info-fetcher-mm8o51t4/download' --output '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md.part' && mv '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md.part' '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): Bash

Original excerpt: Requirements

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md' && test -s '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/evm-tx-info' && cp -R '.skill-downloads/evm-transaction-info-fetcher-mm8o51t4' '.claude/skills/evm-tx-info'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/evm-transaction-info-fetcher-mm8o51t4'

openskills read 'evm-transaction-info-fetcher-mm8o51t4'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/evm-transaction-info-fetcher-mm8o51t4/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
