MetaMask
Users fund their wallet either by purchasing digital assets natively via integrated fiat-to-crypto on-ramp providers (using credit/debit cards, bank transfers, Apple Pay, or Google Pay) or by transferring tokens from an external source.
What is MetaMask?
MetaMask brings together self-custodial architecture and token swaps. Total local control over keys and digital assets. Built-in aggregation functionality to pull pricing quotes from multiple liquidity providers and decentralized exchanges.
Its documented workflow includes: Users navigate decentralized applications (dApps), execute token swaps through integrated liquidity aggregators (such as MetaMask Swaps), or directly trade tokens (including community tokens and memecoins) across supported networks. Every operation—whether a token swap, transfer, or dApp interaction—triggers an explicit prompt requiring the user to review transaction details and sign the action. The platform documentation describes wallet access this way: Non-custodial (self-custody) software wallet.
