A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First time with PayRam? See payram-setup to configure your server, API keys, and wallets.PayRam supports on-chain Bitcoin with a unique architecture: HD wallet derivation for deposits, mobile app signing for sweeps—no private keys ever touch the server.
| Aspect | EVM Chains | Bitcoin |
|---|---|---|
| Deposit addresses | Smart contract generated | HD wallet derived |
| Sweep mechanism | Automated smart contract | Manual mobile app approval |
| Key storage | Keyless (contract-based) | Seed phrase on mobile only |
| Confirmation time | ~15 sec - 2 min | ~10-60 min |
The PayRam Merchant mobile app handles Bitcoin signing:
Security: Seed phrase is encrypted and stored only on your mobile device. Never transmitted to server.
When deposits accumulate:
1. Customer requests payment
2. PayRam derives unique BTC address from your seed (HD wallet)
3. Customer sends BTC to deposit address
4. PayRam detects transaction, waits for confirmations
5. Webhook fires: payment.pending → payment.successful
6. Deposits batch for sweep
7. You approve sweep in mobile app
8. Funds move to your cold walletBitcoin payments use the same API as stablecoin/crypto payments:
const response = await axios.post(
`${PAYRAM_BASE_URL}/api/v1/payment`,
{
customerEmail: '[email protected]',
customerId: 'user_123',
amountInUSD: 50, // PayRam shows BTC equivalent
},
{ headers: { 'API-Key': PAYRAM_API_KEY } },
);
// User redirected to payment page
// Can select Bitcoin as payment method{
"type": "payment.successful",
"data": {
"reference_id": "abc123",
"chain": "bitcoin",
"token": "BTC",
"amountInUSD": 50,
"tokenAmount": "0.00052",
"txHash": "abc123...",
"confirmations": 3
}
}PayRam uses BIP44 derivation to generate unique addresses:
m/44'/0'/0'/0/nBenefits:
Bitcoin requires more confirmations due to longer block times:
| Amount | Recommended Confirmations |
|---|---|
| < $100 | 1 confirmation (~10 min) |
| $100 - $1000 | 3 confirmations (~30 min) |
| > $1000 | 6 confirmations (~60 min) |
