HyperPay vs. MetaMask

What each wallet is built for

MetaMask was built for one job and does it extremely well: giving people a browser and mobile key manager for Ethereum and other EVM chains, so they can sign transactions against decentralised applications. Everything in the product points at that use case — network switching, token approvals, contract interaction, hardware wallet signing, and a plugin ecosystem that assumes you are an active on-chain user.

HyperPay starts from a different question: what does someone need if crypto is not only something they trade, but something they hold, grow and occasionally spend? That produces a wallet with two custody modes in one account, a prepaid HyperCard balance, staking, and collateralized loans. The overlap with MetaMask is real but partial — both hold keys, only one of them is designed around everyday spending.

The practical consequence is that most people who compare these two are not choosing a replacement. They are deciding which wallet holds which part of their portfolio: MetaMask for the assets they actively deploy in DeFi, HyperPay for balances they want stored, earning, or convertible into a spendable card balance.

Where MetaMask wins

MetaMask's biggest advantage is transparency. Its client code is open source, so anyone can review it, fork it, or run their own build. For users whose threat model demands independently verifiable software, that is a decisive difference — HyperPay's core app is not open source, and trust there rests on named third-party audits by SlowMist and CertiK rather than public code review.

The second advantage is ecosystem depth. MetaMask is the default connector for a very large share of EVM decentralised applications, so if your day involves swapping on a DEX, minting, bridging, or interacting with unfamiliar contracts, MetaMask will simply have fewer rough edges. HyperPay provides dApp access but does not attempt to match that breadth of integration.

• Open-source client code, publicly auditable
• Deepest EVM and DeFi integration coverage
• Browser extension workflow purpose-built for contract interaction

Where HyperPay wins

HyperPay's advantage is that holding, earning and spending live in the same account. HyperCard converts crypto into a spendable USD or EUR balance accepted at more than 50 million merchants across 176+ countries, which removes the exchange-then-withdraw-then-wait loop that MetaMask users go through whenever they need to pay for something in the real world.

The custodial option matters too. Self-custody is the right default for experienced users, but seed-phrase loss is still one of the most common ways people permanently lose crypto. HyperPay lets a household keep long-term savings in custodial storage — managed through HyperBC's institutional custody infrastructure — while running a self-custody wallet in the same app for anything they want to control directly.

Built-in staking and collateralized lending complete the picture. In MetaMask those are external protocols you connect to, with the counterparty and contract risk that implies. In HyperPay they are native product features with terms shown before you commit.

Security model compared

In MetaMask, security is almost entirely your responsibility. You hold the seed phrase, you approve every contract, and a malicious approval can drain a wallet without any further confirmation. The upside is that no company can freeze or lose your funds; the downside is that no company can help you recover from a mistake either.

HyperPay splits that responsibility by mode. In self-custody mode the model is the same as MetaMask's — your keys, your responsibility. In custodial mode, key management moves to HyperPay's infrastructure, which reduces user-error risk and introduces platform risk instead. The wallet has operated since 2017 without a publicly reported major security incident, and both SlowMist and CertiK have audited it.

Users who want hardware-level key isolation can pair either wallet with a device. HyperPay integrates HyperMate, whose Sealer2100 secure element is EAL6+ certified and whose firmware is published under Apache 2.0 — the one part of the HyperPay stack that is genuinely open source.

Which one should you choose

Choose MetaMask if your priority is open-source software and heavy DeFi usage on EVM chains, and you are comfortable managing a seed phrase and using a separate exchange whenever you need to convert crypto into spendable money.

Choose HyperPay if you want a single application that stores crypto in either custody mode, earns yield on idle balances, and turns those balances into card spending without a bank account. Many users run both, and that is a perfectly reasonable outcome of this comparison rather than a failure to decide.
