Support covers many blockchains, illustrating MetaMask’s flexibility. Ethereum is still the default network, natively supporting ERC-20 tokens and smart contracts. In addition to this, BSC is economical in transactions, and Polygon improves scalability using its layer-2 solution. integration, included in 2024, addresses high-speed NFT and dApp applications.
Arbitrum and Optimism, other layer-2 chains, optimize Ethereum gas fees, directly accessible through MetaMask’s configuration. Custom networks, e.g., testnets or fresh chains, become part of the list by means of user-provided RPC URLs, so it is adjustable in the decentralized landscape.
