Oviato Documentation

Passkey-based authentication + multi-chain wallet SDK for Bitcoin and EVM chains.

Welcome to Oviato

Oviato is a passkey-based wallet SDK for multi-chain applications. Users sign in with Face ID / Touch ID / security key — no passwords, no seed phrases. One API works across Bitcoin and EVM.

Quickstart

Ship a working sign-in + transfer in 10 minutes.

Core Concepts

Mental model — passkeys, sessions, popup flows, nonce tracker.

Choosing a Package

@oviato/sdk vs @oviato/connect — same API, pick by framework.

Developer Dashboard

Create your app, configure domains, themes, networks.

Explore the SDK

Chain-Agnostic

Works on Bitcoin + EVM with one API — signMessage, sendTransfer, switchNetwork, getBalance.

EVM

evm.* namespace — readContract, multicall, sendTransaction, writeContract, token + NFT helpers, fees, receipts.

UTXO

utxo.* namespace — PSBT signing for Bitcoin, including server-built transactions and counterparty signing.

React Components

OviConnectProvider, useOviConnect, <ConnectButton/>, <Connect/>.

Why Oviato

Passkey authentication — Face ID, Touch ID, or FIDO2 security keys. No passwords, no seed phrases.
Multi-chain with one API — identical surface for Bitcoin + EVM. Switching chains is a one-liner.
Server-side nonce tracker — rapid-fire EVM sends don't collide. You don't manage nonces.
Specialized confirmation sheets — writeContract with an ERC-20 ABI shows a branded "Transfer Token" sheet, not raw hex.
Tiny bundle — ~11 KB gzipped core, ~14 KB with React bindings.
TypeScript-native — full type safety with bigint for EVM, discriminated unions for chain-agnostic returns.

Three-step start

Create your app at dashboard.oviato.com → copy your appId.
Install @oviato/connect (React) or @oviato/sdk (any framework).
Drop in the provider + button:

import { OviConnectProvider, ConnectButton } from '@oviato/connect/client';
import { Network } from '@oviato/connect';

<OviConnectProvider appId="your-app-id" theme="auto">
  <ConnectButton text="Connect" network={Network.BASEMAINNET} />
</OviConnectProvider>

See the Quickstart for the full walk-through including sends and contract calls.
