Platform and billing

#Dashboard

dashboard-ika-accounts.mpckit.xyz is where you manage your platform:

• Overview: balance, transactions and spend over time, recent activity.
• Users: every account created through your platform.
• Activity: each transaction with its status and cost.
• API keys: create and revoke keys.
• Billing: top-ups and charges.
• Settings: allowed origins, webhook URL, team members.

#Billing

Billing is prepaid in US dollars.

1. Top up by sending USDC or SUI on Sui to the treasury address shown under Billing, from a wallet registered to your platform. It is credited automatically.
2. Each sponsored transaction is charged its actual cost, Sui gas and Ika fees, converted at current prices, plus a 0.3% markup.
3. When the balance runs low, new transactions are refused with insufficient_platform_balance. The dashboard shows how many transactions your balance still covers.

Deposits and withdrawals through the funds panel are paid by the user, inside the bridge quote, not from your balance.

#Webhooks

Set a URL in Settings to receive events:

Each request carries x-ika-accounts-timestamp and x-ika-accounts-signature: sha256=<hex>, an HMAC-SHA256 of timestamp + "." + rawBody with your webhook secret. Verify it, and reject timestamps older than 5 minutes. Failed deliveries are retried with backoff for about 7 hours.

import { createHmac, timingSafeEqual } from 'node:crypto';

function verify(rawBody: string, timestamp: string, header: string, secret: string) {
  const expected = createHmac('sha256', secret).update(`${timestamp}.${rawBody}`).digest('hex');
  const age = Date.now() / 1000 - Number(timestamp);
  return age < 300 && timingSafeEqual(Buffer.from(header), Buffer.from(`sha256=${expected}`));
}

Webhook URLs must be public HTTPS endpoints.
