Injected EVM

@usebutr/evm discovers browser EVM wallets (MetaMask, Rabby, Brave, Coinbase, …) through EIP-6963 — the standard where wallets announce themselves via window events instead of fighting over window.ethereum.

Discovery

autoDiscovery() from @usebutr/wallets handles EVM discovery automatically. For an EVM-only setup, wire it directly with createWalletSource:

import { createWalletSource } from "@usebutr/core";
import { discoverEvmAdapters } from "@usebutr/evm";
import { WalletManagerProvider } from "@usebutr/react";

const discovery = createWalletSource(discoverEvmAdapters);

<WalletManagerProvider discovery={discovery}>
  {children}
</WalletManagerProvider>

Injected fallback

Some regional / legacy wallets only expose a raw EIP-1193 window.ethereum and never announce via EIP-6963. discoverInjectedAdapter is the last-resort fallback for them. When using autoDiscovery() the injected flag is controlled by DiscoverOptions and defaults to true whenever evm is enabled.

import { discoverInjectedAdapter, GENERIC_INJECTED_ICON } from "@usebutr/evm";

Capabilities

Derived from the wallet's EIP-6963 provider info / RPC inspection. Typically all of getBalance, sendTransaction, signMessage, subscribe, switchChain are true; requestAccounts is true for wallets that honour wallet_requestPermissions. Always branch on wallet.connector.capabilities rather than assuming.

Chain switching

EVM connectors switch chains for real via wallet_switchEthereumChain. Use EVM_CHAINS_LIST (or CHAINS_BY_PLATFORM.evm from @usebutr/wallets) for the chain list — see multi-chain.

Helpers

@usebutr/evm also exports byte/hex utilities used by adapters and handy in app code: bytesToHex, hexToBytes, chainIdHexToDecimal, chainIdDecimalToHex, formatEther.
