# ERC-20 Tokens

Read balances and move tokens without hand-rolling the calls

## What this does

Most tokens on Ethereum follow the same standard, so the same handful of calls covers nearly all of them. This gives you those calls from C#: balances, transfers, approvals, allowances, and the basic facts about a token. Reach for it any time your .NET app has to touch a token.

### Top 3 things it does for you

- Check a wallet's token balance
- Send tokens from one address to another
- Approve a spender and check the allowance

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is ERC-20 Tokens safe to install?

AIR scanned this exact version of ERC-20 Tokens and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 1d68d2b03605, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/erc20.

### How do I install ERC-20 Tokens?

Open https://airmarket.ai/app/erc20 on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/Nethereum/Nethereum/tree/1d68d2b036054226a11179eb1d1bda57f30a5365/plugins/nethereum-skills/skills/erc20. Install from that link, not the branch.
