Exposes a simple useGraphAuthKit hook that lets the app open the connect modal, letting users connect to their wallet of choice (one of: injected/MetaMask, coinbase, WalletConnect, Safe). See integration example below.

Install

Currently, graph-auth-kit has a lot of peer deps needed to interact with the library. But this may change after testing. At the very least, wagmi, viem, @tanstack/react-query will be needed.

# with bun
bun add @edgeandnode/graph-auth-kit \
  @edgeandnode/common \
  @edgeandnode/gds \
  @edgeandnode/go \
  @emotion/react \
  @tanstack/react-query \
  cookies-next \
  ethers@5.7.2 \
  theme-ui \
  viem@2.x \
  wagmi

# with pnpm
pnpm add @edgeandnode/graph-auth-kit \
  @edgeandnode/common \
  @edgeandnode/gds \
  @edgeandnode/go \
  @emotion/react \
  @tanstack/react-query \
  cookies-next \
  ethers@5.7.2 \
  theme-ui \
  viem@2.x \
  wagmi

Usage

Properties:

config -> [REQUIRED]. The instantiated wagmi config instance.
queryClient -> [OPTIONAL]. The GraphAuthKitProvider renders a QueryClientProvider instance. Pass in an instantiated QueryClient to use, otherwise, GraphAuthKit will instantiate its own.
infuraKey -> [REQUIRED]
gatewayApiKey -> [OPTIONAL]. A The Graph Gateway API key used to query Subgraphs published on the Graph Network. Used for ENS name resolution

Example

Setup the GraphAuthKitProvider.
- Note you do not need to add the ConnectModal component, the GraphAuthKitProvider renders it for us
- Note you do not need to add the QueryClientProvider as GraphAuthKitProvider instantiates and renders it
  - you can pass a QueryClient instance to the GraphAuthKitProvider, otherwise, it will instantiate its own

Usage in a component

// components/Layout.tsx

import { ReactNode } from 'react'
import { useAccountEffect, useEnsName } from 'wagmi'

import { Layout as GDSLayout, UserProfile } from '@edgeandnode/gds'
import { GlobalFooter, GlobalHeader, NPSForm } from '@edgeandnode/go'
import { L1Chain, useGraphAuthKitConnector, useGraphAuthKit, useGraphAuthKitAccount } from '@edgeandnode/graph-auth-kit/hooks'

import { NavDropDownMenu } from './NavDropDownMenu'

export function Layout({ children }: Readonly<{ children: ReactNode }>) {
  const authkit = useGraphAuthKit()
  const { address } = useGraphAuthKitAccount()
  const { data: ens } = useEnsName({ address, blockTag: 'latest', chainId: L1Chain.id })
  const connector = useGraphAuthKitConnector()

  const walletConnected = Boolean(address)

  useAccountEffect({
    onConnect(data) {
      console.log('user connected wallet', {data})
    },
    onDisconnect() {
      console.log('user disconnected wallet')
    },
  })

  return (
    <GDSLayout
      header={
        <GlobalHeader
          activeProduct="EXPLORER"
          basePath="/explorer"
          showSupportButton={walletConnected}
          rigtContent={(defaultContent) => (
            <>
              {!walletConnected ?
                <GlobalHeader.ConnectButton onClick={() => authkit.openConnectModal()} />
              ) : (
                <UserProfile
                  ethereumAccount={address}
                  graphAccount={...}
                  ens={ens}
                  profileUrl={`/profile/${address}?view=Overview`}
                  profileUrlAs={`/profile/${address}?view=Overview`}
                  onConnect={() => authkit.openConnectModal()}
                  onDisconnect={() => authkit.disconnect()}
                  userDropDownMenu={<NavDropDownMenu />}
                  accountTag={connector === 'safe' ? 'multisig' : undefined}
                />
              )}
            </>
          )}
        />
      }
      footer={
        <>
          <NPSForm sx={{ mb: Spacing['64px'] }} />
          <GlobalFooter />
        </>
      }
    >
      {children}
    </GDSLayout>
  )
}

Hooks

useGraphAuthKitAccount -> This is an override of the wagmi useAccount hook. The reason is, if the user connects with a multisig, the wagmi context is connected with the user-selected EoA, so all of the wagmi context hooks reference this EoA and not the Safe. This returns the wagmi UseAccountReturnType but the address and addresses values include the entered Safe address. It also adds an eoa property that is the connected EoA address.
useGraphAuthKitConnector -> The user selected wallet/connector option.
useClientToEthersSigner -> Returns the ethers@5.x.x JsonRpcSigner or SafeEthersSigner if the user is connected via a multisig
useAuthAccount -> similar to the useGraphAuthKitAccount but requires the user to be authenticated and throws an error if not
useGraphAuthKitAccountEffect -> Override of the wagmi useAccountEffect hook that listens to account changes and the _enteredMultisigInfo on the inner context instance. If the account data changes, emits a onConnect or onDisconnect event, but in the onConnect also checks the useGraphAuthKitInnerContext()._enteredMultisigInfo value and if the user has connected via a multisig, returns the mutlsig as the address value and the connected EoA as the eoa value.
useGraphAuthKitWalletClient -> Override of the wagmi useWalletClient hook that returns the extended Safe viem actions if the user is connected to a multisig.
useGraphAuthKitWriteContract -> Override of the wagmi useWriteContract hook that creates the transaction on the Safe if the user is connected via multisig; otherwise, returns the useWriteContract mutation hook.

Components

Connected -> renders the passed in children only if the user is connected.

import { Connected } from '@edgeandnode/graph-auth-kit'

export function ShowMeConnected() {
  return <Connected>{(account) => <div>Connected Wallet: {account.address}</div>}</Connected>
}

Disconnected -> renders the passed in children only if the user id disconnected. Useful for rendering components like a "Connect Wallet" CTA that should only render if the user is not authenticated.

import { ExperimentalButton as Button } from '@edgeandnode/gds'
import { Disconnected, useGraphAuthKit } from '@edgeandnode/graph-auth-kit'

export function ShowMeDisconnected() {
  const authkit = useGraphAuthKit()

  return (
    <Disconnected>
      <Button variant="primary" onClick={() => authkit.openConnectModal()}>
        Connect Wallet
      </Button>
    </Disconnected>
  )
}

SwitchChain -> Similar to the SwitchNetwork component from GDS, but uses the wagmi useSwitchChain hook.

import { ExperimentalButton as Button } from '@edgeandnode/gds'
import { L2Chain, SwitchChain } from '@edgeandnode/graph-auth-kit'

export function LetMeSwitchChain() {
  return <SwitchChain requestedChain={L2Chain} />
}
