Deployment scope

This faucet client funds the documented Mina-backed Zeko network. It does not supply ETH on the Ethereum rollup. See current testnet funding.

Faucet CLI

Command-line client for the legacy Zeko-M testnet faucet. Claim legacy test tokens and verify your GitHub authentication from the terminal.

This faucet does not fund Ethereum Sepolia or the Ethereum-backed Zeko testnet. See the current getting-started guide for ETH funding.

Written in Rust for fast startup and single-binary distribution. Distributed via npm with platform-specific packages.

The CLI is maintained in the private Zeko monorepo and mirrored to zeko-labs/faucet-cli for issues and releases.

Installation

Install globally:

npm install -g @zeko-labs/faucet-cli

Or run without installing via npx:

GITHUB_TOKEN=ghp_xxx npx -y @zeko-labs/faucet-cli whoami

Supported platforms

Platform	Package
macOS arm64	@zeko-labs/faucet-cli-darwin-arm64
macOS x64	@zeko-labs/faucet-cli-darwin-x64
Linux x64	@zeko-labs/faucet-cli-linux-x64

The correct platform package is installed automatically via optionalDependencies.

Authentication

Every command requires a GitHub personal access token (classic or fine-grained). Each command accepts the token in this order:

1. --token <value> flag (highest priority)
2. GITHUB_TOKEN environment variable

# Using the flag
zeko-faucet whoami --token ghp_xxx

# Using the environment variable
export GITHUB_TOKEN=ghp_xxx
zeko-faucet whoami

Commands

whoami

Verify your GitHub token and display the associated account.

GITHUB_TOKEN=ghp_xxx zeko-faucet whoami
zeko-faucet whoami --token ghp_xxx
GITHUB_TOKEN=ghp_xxx zeko-faucet whoami --json

Example output:

Authenticated as octocat (#1).
Name: The Octocat
Profile: https://github.com/octocat
Created: 2011-01-25T18:44:36Z
Token source: env

claim <address>

Submit a faucet claim for the given Mina address on the zeko-m:testnet chain.

GITHUB_TOKEN=ghp_xxx zeko-faucet claim B62qexample
zeko-faucet claim B62qexample --token ghp_xxx
GITHUB_TOKEN=ghp_xxx zeko-faucet claim B62qexample --json

Example output:

Claim submitted for B62qexample.
Chain: zeko-m:testnet
Amount: 100
Transaction: 5Jtxxx
Explorer: https://zekoscan.io/devnet/tx/5Jtxxx

Command Options

Both whoami and claim support the same options:

Flag	Description
--token	GitHub personal access token (overrides GITHUB_TOKEN)
--json	Emit machine-readable JSON instead of human text

Exit Codes

Code	Meaning
0	Success
1	General error
2	Authentication error
3	Rate limited
4	Invalid address

Scripts and CI pipelines can use exit codes to branch on specific failure types:

zeko-faucet claim B62qexample
case $? in
  0) echo "Claim succeeded" ;;
  2) echo "Bad token — check GITHUB_TOKEN" ;;
  3) echo "Rate limited — try again later" ;;
  4) echo "Invalid Mina address" ;;
  *) echo "Something went wrong" ;;
esac

JSON Mode

Pass --json to any command for machine-readable output suitable for piping into jq or other tools.

Success:

{
	"success": true,
	"address": "B62qexample",
	"chain": "zeko-m:testnet",
	"amount": "100",
	"hash": "5Jtxxx",
	"explorer_url": "https://zekoscan.io/devnet/tx/5Jtxxx"
}

Error:

{
	"success": false,
	"code": "rate_limited",
	"message": "You have already claimed tokens recently."
}
