Fund Your Vault: Credit Cards, Crypto, and Direct Transfer

For users who prefer standard financial instruments, Inheribase integrates with Polar.sh, which uses Stripe under the hood, to provide institutional-grade fiat merchant processing.

Supported methods

Payment method	Processor	Availability
Visa / Mastercard / Amex	Stripe	Worldwide
Apple Pay	Stripe	iOS, macOS Safari
Google Pay	Stripe	Android, Chrome

How it works

1

Open credits settings

Navigate to Settings → Credits in your dashboard.

2

Enter your amount

Enter your desired top-up amount. The minimum for card payments is $20.00.

3

Choose Pay with Card

Select Pay with Card to open Polar’s secure checkout interface.

4

Complete checkout

Complete the transaction through Polar’s payment flow.

5

Credits applied

Vault Credits are deposited to your account instantly upon payment confirmation.

Card payments require a **minimum deposit of

20.00** to cover third-party processing overhead. At current rates, even a

20 deposit covers significant long-term storage or over 100 on-chain health checks.

Receipts and invoicing

Polar automatically handles:

Email receipts for every transaction
Standardized invoicing for tax and estate documentation
Merchant transparency — payments are processed through verified channels with full dispute protection

For estate attorneys and wealth managers, Polar invoices are accepted as standard business receipts. For customized institutional invoicing, contact support@inheribase.com.

Inheribase leverages MoonPay Commerce for a seamless, guided checkout experience for users who want to pay with crypto but prefer a polished web interface rather than a raw on-chain transfer.

Supported assets

We recommend USDC on Base for optimal performance and smart contract integration, but MoonPay supports a range of assets:

Asset	Network	Efficiency
USDC	Base Mainnet	Optimal (instant / low fee)
ETH	Base Mainnet	High
USDC / ETH	Ethereum Mainnet	Standard

How it works

1

Open credits settings

Navigate to Settings → Credits in your dashboard.

2

Enter your amount

Enter your desired top-up amount.

3

Choose Crypto

Select Crypto (via MoonPay) to launch the checkout widget.

4

Complete the MoonPay widget

The MoonPay Checkout Widget opens. Select your preferred wallet or enter payment details if purchasing crypto directly through MoonPay.

5

Credits applied automatically

Credits are detected and deposited once the transaction confirms via MoonPay’s webhook. No manual action required.

For advanced users or those who prefer a purely non-custodial path, Inheribase provides the Sovereign Path: send USDC directly to the Inheribase Treasury address, bypassing all middleman fees and third-party interfaces.

Benefits

0% protocol fees — no provider markups; you pay exactly the cost of credits
Universal compatibility — works from MetaMask, Coinbase App, Binance, or any wallet or exchange
Permanent availability — does not depend on a third-party API being online

How it works

1

Choose Direct Sovereign Transfer

In the Dashboard, select Direct Sovereign Transfer (Expert Path).

2

Transfer USDC

Choose your transfer method:

1-Click Transfer — if you have a browser wallet (MetaMask, Coinbase Wallet, etc.) connected, click the 1-Click button to authorize instantly.
Manual Transfer — scan the displayed QR code or copy the Treasury Address to send USDC from an exchange (Binance / Coinbase / Kraken).

3

Submit transaction hash (manual only)

If you sent manually, paste your Transaction Hash into the verification field to clear the credits.

4

Credits applied

The Inheribase backend autonomously validates the on-chain transfer and applies credits to your ledger.

Only send USDC on Base Mainnet (Chain ID: 8453). Sending tokens on any unsupported network will result in lost funds that Inheribase cannot recover. Double-check your network selection before confirming any transaction.
