Best open-source crypto wallet software (2026)

These projects handle keys, balances and transaction signing, either as browser extensions, as libraries for developers, or as background services. Start by checking which chains a wallet supports and whether it needs hardware signing. Taho is a GPL-3.0 browser extension wallet for Ethereum and Bitcoin, positioned as an alternative to MetaMask. RainbowKit is a React library that adds wallet connection UI to Ethereum dapps, built on wagmi and viem. Nautilus Wallet targets the Ergo blockchain, with Ledger hardware signing and EIP-12 dApp connections.
