Best for self-custody users

of 10

Meridian Spend is the standout choice for users unwilling to hand assets to a custodian, authorising each payment from their own wallet. The trade-off is added complexity and per-transaction gas costs that suit deliberate rather than high-frequency spenders.

Pros

Spends directly from a self-custodied wallet via smart-contract authorisation
No pre-funding required; balance stays in your control until settlement
Non-custodial model reduces exchange counterparty risk

Cons

On-chain settlement adds a gas cost to each transaction
Steeper learning curve for users new to wallet-based spending

Overview

Meridian Spend takes a non-custodial approach: rather than pre-loading a balance, the card authorises spending against a smart-contract allowance connected to your self-custodied wallet. At settlement, the contract pulls the required stablecoin. Assets remain under your keys until the moment of purchase.

Fees & costs

There is no monthly fee and a flat 0.75% base reward. The distinctive cost is network gas: each settlement is an on-chain transaction, so Meridian routes through low-fee layer-2 networks like Base and Arbitrum to keep costs down. FX markup is modest, and there are no top-up spreads because nothing is pre-converted.

Security

Security is the core selling point. Because funds never leave your wallet until settlement, there is no custodial honeypot. The allowance contract is audited and revocable at any time, and users set spending caps directly on-chain. The flip side is that key management responsibility rests entirely with the user.

Who it's for

Meridian fits self-custody advocates comfortable with wallets and gas. It is less ideal for those wanting a simple tap-and-go experience or very frequent small purchases where gas overhead accumulates.
