How to buy Mainframe

There’s no fixed minimum amount of Mainframe that can be purchased on MetaMask. The minimum purchase depends on the onramp provider and payment method—many providers support Mainframe purchases starting around ~$1–$5.

Mainframe can be purchased on MetaMask using a debit card, credit card, bank transfer, Apple Pay, Google Pay, PayPal, and other regional options. MetaMask displays all methods available in the buyer’s location at the time of purchase.

No exchange account is needed to buy Mainframe on MetaMask. MFT is purchased through integrated, leading onramp providers directly inside your MetaMask wallet.

Buying Mainframe on MetaMask delivers MFT to a self-custodial wallet—you control your funds from the moment of purchase, no third party can freeze or restrict access to these assets. On a centralized exchange, the platform holds MFT in a custodial account and controls the wallet funds on the buyer’s behalf.

MetaMask is a self-custodial wallet with millions of monthly active users. MFT purchased via MetaMask is controlled by the buyer—not by MetaMask or any third party. MetaMask's code is open source, independently audited, and backed by a bug bounty program. Built-in security features include Blockaid-powered alerts for malicious requests and Smart Transactions for MEV protection. All purchases are processed through regulated onramp providers, and Private Keys are stored locally on the buyer's device.
