# Copy to .env and fill in. `.env` is gitignored; this file is not — so never
# put a real key in here.

#   cp .env.example .env
#   npm run example:roundtrip

# The HIERO_* names are not ours: `@hiero-hackers/enterprise-core` reads them
# itself via resolveConfigFromEnv(), so the examples do no env plumbing.

# ── Required: a funded TESTNET account ───────────────────────────────────
# Create one and fund it free at https://portal.hedera.com (testnet faucet).
# Testnet HBAR has no value, so this costs nothing.
#
# NEVER put a mainnet key here. The roundtrip example refuses to run on any
# network but testnet, and a key in a file is a key you will eventually paste
# somewhere by accident.

# ── Optional: who gets paid ──────────────────────────────────────────────
# An existing testnet account for the roundtrip example to pay. Leave blank and
# it creates a throwaway one — the payer and payee must differ, since paying
# yourself nets to zero and credits nobody.

# ── Optional: where the receipt goes ─────────────────────────────────────
# A Discord *incoming webhook* URL. Note this posts to a CHANNEL, not to a
# person — DMing a user needs a bot with OAuth, which is a different thing.
# Server Settings → Integrations → Webhooks → New Webhook → Copy URL.
# Anyone holding this URL can post to that channel. Treat it as a secret.

# A Slack incoming webhook URL, same idea.
