MetaMask Enhances Wallet With Smart Contracts, BTC & SOL Support

MetaMask, the leading self-custodial Ethereum wallet, has unveiled major updates to improve user experience and security. Announced at ETHDenver, these upgrades introduce smart contract capabilities, transaction batching, and expanded blockchain support.

Currently, MetaMask operates as an Externally Owned Account (EOA), controlled by a public and private key. However, losing the private key results in irreversible loss of funds. To address this, MetaMask plans to integrate Contract Accounts (CAs), which offer built-in recovery mechanisms and enhanced security.

A key enhancement includes ERC-5792, enabling batched transactions. This feature lets users combine multiple transaction steps—such as “approve + swap”—in one click, reducing gas fees and streamlining processes. MetaMask co-founder Dan Finlay emphasized that this upgrade will improve efficiency by presenting users with a unified transaction process and a single gas fee.

Additionally, the MetaMask debit card, previously available in the UK and EU, will launch in select U.S. states by mid-March. The card allows users to spend crypto seamlessly, even while earning staking rewards, anywhere Mastercard is accepted.

Expanding beyond Ethereum, MetaMask will soon support Bitcoin (BTC) and Solana (SOL), making it a more comprehensive multi-chain wallet. Finlay noted that these integrations ensure a smoother user experience while simplifying cross-chain asset management.

With these updates, MetaMask is reinforcing its position as a leading crypto wallet, prioritizing security, usability, and multi-chain support.
