Wallet provider MetaMask is launching a crypto payments card that will allow users to spend self-custodied funds, offering crypto holders additional ways to use their tokens.

The new card is backed by Mastercard and is being developed in partnership with CompoSecure and Baanx, according to the company. The product uses smart contracts to execute the IRL (In Real Life) transactions, with a processing speed under five seconds. It operates on the Linea network, a layer-2 scaling solution on Ethereum.

The companies marketed the self-custodied crypto card as an alternative to the potential risks associated with centralized exchanges. In February, the second-largest crypto exchange by volume, Bybit, was hacked for $1.4 billion, an event that sparked widespread consternation in the crypto space.

With the launch of its card, MetaMask is entering a competitive segment of the cryptocurrency market. Major exchanges like Binance, Bybit, Coinbase, and Crypto.com already offer crypto debit cards, some of which feature “crypto-back” rewards that allow users to earn digital assets on their purchases.

MetaMask has struggled lately as interest in and participation in the Ethereum ecosystem have dried up. According to Dune Analytics, the wallet collected just $289,312 in fees for the week of April 14, much less than the $1.3 million in fees collected for the same period a year ago.

Stablecoin, BTC payments growing use cases for crypto

Payments have emerged as one of the fastest-growing use cases for cryptocurrencies in 2025, offering a way to bring real-world utility to digital assets.

Luxury brands like Dorsia have begun accepting various cryptocurrencies as payment, while messaging app Signal is reportedly exploring adopting Bitcoin for peer-to-peer transactions, and a bill in New York has been introduced to legalize the use of Bitcoin and other cryptocurrencies for state payments.

Despite growing competition from emerging issuers, the stablecoin market remains largely dominated by a few key players. According to data from Web3 research firm Nansen, Tether’s USDt continues to lead among US dollar-pegged stablecoins, even as competition intensifies.

As of April 25, Tether (USDT) has a roughly 66% market share among stablecoins, compared to around 28% for USDC (USDC), Nansen said in the April 25 report. Ethena’s USDe stablecoin ranks a distant third, touting a market share of just over 2%.

Nansen expects Tether’s lead to endure even as rivals such as USDC clock faster growth rates.

“With nearly 3x as many users as Uniswap and 50+% more transactions than the next app, Tether is by and far the largest use case of onchain activity,” Nansen said.

“Despite the potential dispersion in stables, we inevitably believe this is a ‘winner-takes-most’ market dynamic,” the Web3 researcher added.

Tether is also the most profitable stablecoin issuer, clocking nearly $14 billion in 2024 profits. The company earns revenue by accepting US dollars to mint USDT and subsequently investing those dollars into highly liquid, yield-bearing instruments such as US Treasury bills. 

“Given the growth of USDT and USDC, the users are clearly expressing that they do not necessarily care about the yield as they are forgoing it to Tether and Circle -they simply want access to the most liquid and ‘stable’/ least-likely-to-depeg stablecoin out there,” Nansen said.

Competitive landscape

Adoption of USDC has accelerated since November, when US President Donald Trump’s election victory ushered in a more favorable US regulatory environment for crypto, Nansen said.

Circle’s US-regulated stablecoin has been “particularly attractive to institutions requiring regulatory clarity,” the report said.

But USDC now faces “intensifying competition as major traditional financial institutions (i.e., Fidelity, PayPal, and banks) enter the market,” Nansen said, adding that stablecoins, including PayPal’s PYUSD and Ripple USD, are “rapidly gaining traction.” 

On April 25, payment processor Stripe tipped plans to create a new stablecoin product of its own after buying stablecoin platform Bridge last year.

Despite its smaller market share, Ethena’s yield-bearing USDe stablecoin remains “competitive on most fronts moving forward,” partly because of integrations across centralized exchanges (CEXs) and decentralized finance (DeFi) protocols, the report said.

Since launching in 2024, Ethena’s stablecoin has generated an average annualized yield of approximately 19%, according to Ethena’s website.

Lawmakers in the Arizona House of Representatives have voted to pass two bills that could allow the state to adopt a reserve using Bitcoin (BTC) or other cryptocurrencies.

In a third reading on April 28 of the Senate Bill 1025 (SB1025), a proposal to amend Arizona’s statutes to allow for a strategic BTC reserve, 31 members of the Arizona House voted in favor of the bill, with 25 opposed. A similar bill, SB1373, to establish a state-level digital assets reserve, passed with 37 lawmakers in favor and 19 voting nay.

“This bill basically takes the approach that probably 15 other states are considering the same legislation nationwide that allows the treasurer to invest up to 10% into, probably mainly Bitcoin but other things as well,” said State Representative Jeff Weninger on SB1025. “I think this probably would start as a ‘may’ for the foreseeable future, but as things continue to pivot towards Bitcoin and these things, would have that already in place in the future.”

The approvals bring the bills closer than any other state-level initiative in the US to getting a cryptocurrency or Bitcoin strategic reserve signed into law. Similar legislation proposed in New Hampshire passed the state’s House in April and is expected to head to the Senate for a full floor vote soon.
