MetaMask advances towards a unified crypto wallet with Solana and Bitcoin

MetaMask spent years as the default gateway to Ethereum, the browser extension that turned “connect wallet” into muscle memory for millions of users.

Now Consensys is betting that same reflex can work across blockchains. In late May, MetaMask flipped the switch on native Solana support, letting its 30 million monthly active users manage SOL and SPL tokens without installing Phantom or any other Solana-first wallet.

Bitcoin support sits somewhere on the 2025 roadmap, initially slated for the third quarter but not yet shipped.

If it lands, MetaMask will become the first primary wallet to natively support Ethereum, Solana, and Bitcoin. These three ecosystems have historically required separate apps, seed phrases, and mental models.

The timing isn’t subtle. Artemis data from June showed that Solana’s monthly active addresses matched those of every other layer-1 and layer-2 network combined.

Solana stopped being the “Ethereum alternative” and started looking like the place where actual users were showing up.

For MetaMask, that created an uncomfortable dynamic: the wallet with the largest distribution was missing the chain with the most activity.

Phantom, the Solana-native incumbent with 15 million monthly active users (MAUs) and $25 billion in user assets, had already made the opposite move, adding support for Ethereum and Bitcoin throughout 2024.

The multichain wallet wasn’t a future concept; it was already here, and MetaMask was late.

The UX thesis: one account, three rails

What MetaMask is proposing goes beyond feature parity. The product now offers a unified portfolio view across Ethereum and Solana, with swaps and bridges built directly into the interface.

Users can import existing Solana wallets using the same Secret Recovery Phrase that governs their Ethereum keys, collapsing what used to be a multi-app juggling act into a single session.

When Bitcoin support arrives, the loop closes: one recovery phrase, one interface, three entirely different consensus mechanisms and cryptographic schemes.

The convenience is obvious. The risk is less discussed but harder to ignore. A single seed phrase now controls secp256k1 keys for EVM chains and ed25519 keys for Solana, with Bitcoin’s key derivation next in line.

One compromised backup exposes every chain simultaneously. Consensys has published security guidance around the multichain model, but the trade-off remains: blast radius versus ease of use.

An extension bug earlier this year that caused MetaMask to write excessive data to SSDs on some Chromium setups didn’t help the reliability narrative.

Consensys shipped a fix, but the episode underscored how extension-level failures can erode trust faster than feature announcements build it.

This is where account abstraction comes into play. Consensys pairs the multichain rollout with its Delegation Toolkit and the upcoming EIP-7702 standard in Ethereum’s Pectra upgrade.

These tools enable gas sponsorship, transaction batching, and session-style permissions, which compose the software layer that lets wallets hide seed phrases entirely and execute multi-step flows without repeated approvals.

The result is what the industry calls “invisible wallets,” where users interact with apps without ever thinking about keys, gas, or chain IDs.

It’s a compelling vision, but EIP-7702 also opens new avenues for phishing. Malicious dapps can request broad permissions that let them act on behalf of users, and distinguishing legitimate requests from scams becomes the wallet’s job.

MetaMask’s security alerts and how aggressively it surfaces warnings around delegate permissions will matter as much as the UX improvements themselves.

Shelf space as distribution

Wallet interfaces have become the new homepage.

If MetaMask surfaces Solana dApps, stablecoin bridges, and memecoin swaps in the default view, millions of EVM-native users will sample Solana not because they researched the ecosystem but because the path of least friction pointed them there.

The same logic applies to Bitcoin. Daily active addresses on Bitcoin routinely range from 700,000 to 1 million, and ordinals plus inscriptions have turned BTC into something more than a savings asset.

A native Bitcoin tab inside MetaMask would let Ethereum and Solana users experiment with Bitcoin-based collectibles or Lightning payments without switching contexts, and it would give Bitcoin-first users a reason to try stablecoin swaps or DeFi protocols on faster chains.

The strategic question is whether distribution alone can shift ecosystem gravity. MetaMask’s 30 million MAUs dwarf Phantom’s 15 million, but Phantom owns mindshare among Solana users and has spent years building tooling around NFTs, token launches, and social discovery.

If MetaMask converts even 10% to 18% of its user base into active cross-chain participants within the first few weeks, it could mean several million people suddenly browsing Solana dapps from an Ethereum wallet.

It’s not a winner-take-all outcome but reframes the competitive landscape. Phantom will likely double down on power features and community-driven discovery, leaning into what made it the default for Solana natives in the first place.

MetaMask is betting that “good enough” cross-chain UX plus account abstraction rails will be more valuable than specialized depth.

The regulatory shadow and the super-app endgame

The SEC sued Consensys in June 2024, alleging that MetaMask Swaps and staking features generated more than $250 million in fees without proper broker registration.

Consensys is contesting jurisdiction, and the case hasn’t killed momentum, but it adds a layer of uncertainty to every product expansion.

Each new chain, swap route, and revenue stream invites fresh scrutiny.

Meanwhile, OKX Wallet operates as a full-fledged super-app, supporting 100+ chains and smart account features, demonstrating what’s possible when regulatory constraints are lighter.

Coinbase Smart Wallet took a different path entirely, using passwordless flows and embedded wallets to push past 1 million accounts created over the summer, all on Base, all EVM, no Solana or Bitcoin in sight.

Coinbase targets users who don’t know they’re using a wallet, arguably the real endgame for mainstream adoption.

MetaMask sits in the middle: too visible to avoid regulation, too decentralized to pivot into a fully custodial model, and too large to ignore the chains where users are actually spending time.

The multichain push is as much about survival as it is about ambition. If wallet market share becomes a proxy for ecosystem influence, then the wallet that spans the most chains with the least friction controls where the next cohort of users lands.

Phantom was first on Solana and Bitcoin, while MetaMask is trying to be first with “everything at once.”

The wallet wars have shifted from key management to defaults. Whoever owns the first tap, consisting of the initial connection, the first swap, and the chain that loads when a new user opens the app, will steer where millions of people think crypto happens.

If MetaMask’s Bitcoin integration ships before year-end, 2026 will open with a single interface that treats Ethereum, Solana, and Bitcoin as tabs in the same browser rather than separate universes. At that point, the question isn’t which chain wins; it’s which wallet decides.
