Monolith Card Review

Monolith Card Review: The Ethereum-Native Visa Card

Monolith (formerly TokenCard) is a non-custodial Ethereum Visa debit card — meaning you connect your own Ethereum wallet directly to the card, rather than depositing funds into a centralised platform. This makes Monolith unique in the crypto card space.

How It Works

1. Create a Monolith Contract Wallet (a smart contract wallet on Ethereum)
2. Top up the wallet with ETH or ERC-20 tokens
3. When you spend on the card, tokens are automatically converted to GBP/EUR and settled via Visa

The key differentiator: your funds are in your smart contract wallet, not held by a central company. You control the private key.

Supported Assets

• Ethereum (ETH)
• Major ERC-20 tokens (DAI, USDT, USDC, and others)
• New tokens can be added via the Monolith smart contract system

Smart Contract Wallet Features

• Top-up whitelist: You set a whitelist of addresses that can top up your card wallet
• Spending limit: Set daily spending limits enforced by the smart contract
• Community chest: 1% of top-ups goes to a community-governed fund for public goods

Availability

Monolith is available in the UK and European Economic Area (EEA). Not available in the US.

Considerations

• Ethereum mainnet (gas fees apply on top-ups and transactions)
• Non-custodial approach means more complexity for non-technical users
• Smaller user base and less customer support than mainstream crypto cards
• GBP/EUR Visa card (not USD)

Verdict

Monolith is a pioneering product for the DeFi-native audience who want a spending card without giving up custody of their funds. For mainstream users or those who want simplicity, the Coinbase Card or Crypto.com Card may be more suitable.
