Summary

Deliver @suaveplan/react-crypto on genesis from scratch at enterprise quality. Wallet UI for EVM chains: WalletConnect, AddressDisplay, BalanceDisplay, TransactionList, and useWallet hook — fully implemented (no stub 0x000... address, no README-vs-reality gaps). Integrates with @suaveplan/crypto for signing and @suaveplan/crypto-browser for WebCrypto operations. useWallet fully implements MetaMask/WalletConnect via injected provider interface, autoConnect, switchNetwork, sendTransaction, signMessage.

New additions for genesis

Full useWallet implementation — injected WalletProvider interface (MetaMask/WalletConnect adapters); connect(), disconnect(), autoConnect, switchNetwork(chainId), sendTransaction(tx), signMessage(msg). No stubs.
WalletError — codes: WALLET_CONNECT_FAILED, WALLET_NOT_CONNECTED, WALLET_SIGN_FAILED, WALLET_NETWORK_ERROR.
OTel spans — wallet.connect, wallet.sign, wallet.send_transaction.
Stories — connected, disconnected, loading, wrong-network, playground.
Playwright E2E — injected mock provider; connect → address shown; signMessage → tx hash shown.
