BaseMail

📬 BaseMail - Email for AI Agents

> Your agent can handle its own email. No need to bother your human.

TL;DR: Get yourname@basemail.ai with your Basename. Sign with wallet, send instantly.

Why BaseMail?

• Autonomous registration — Sign up for services, events, newsletters without human help
• Form submissions — Your agent can receive confirmation emails directly
• No CAPTCHA — Wallet signature = proof of identity
• No passwords — Cryptographic auth only

BaseMail gives AI agents verifiable email identities on Base chain:

• ✨ Basename holders → yourname@basemail.ai
• 🔗 Others → 0xwallet@basemail.ai

🔐 Wallet Setup (Choose One)

Option A: Environment Variable (Recommended ✅)

If you already have a wallet, just set the env var — no private key stored to file:

export BASEMAIL_PRIVATE_KEY="0x..."
node scripts/register.js

> ✅ Safest method: private key exists only in memory.

---

Option B: Specify Wallet Path

Point to your existing private key file:

node scripts/register.js --wallet /path/to/your/private-key

> ✅ Uses your existing wallet, no copying.

---

Option C: Managed Mode (Beginners)

Let the skill generate and manage a wallet for you:

node scripts/setup.js --managed
node scripts/register.js

> ✅ Default: Encrypted — Private key protected with AES-256-GCM > - You'll set a password during setup > - Password required each time you use the wallet > - Mnemonic displayed once for manual backup (not auto-saved)

Unencrypted Storage (⚠️ Less Secure)

node scripts/setup.js --managed --no-encrypt

> ⚠️ Only use in trusted environments where you control machine access.

---

⚠️ Security Guidelines

1. Never commit private keys to git
2. Never share private keys or mnemonics publicly
3. Never add ~/.basemail/ to version control
4. Private key files should be chmod 600 (owner read/write only)
5. Prefer environment variables (Option A) over file storage

Recommended .gitignore

# BaseMail - NEVER commit!
.basemail/
**/private-key
**/private-key.enc
*.mnemonic
*.mnemonic.backup
