LightLink Wallets - SODAX Docs

Welcoming cross-network users means supporting the wallets they already use. On LightLink, SODAX works with any wallet that can sign EVM transactions on LightLink Phoenix mainnet (chain ID 1890), such as MetaMask. On the networks your users arrive from, it is Phantom, Suiet, Lobstr, and more. SODAX gives you both through one interface, so wallet plumbing never becomes the integration.

Account requirements

ETH for gas. The signing account needs ETH on LightLink. Holding only LL or other tokens is not enough: the SDK sends standard gas-paying transactions, not LightLink Enterprise Mode ones.

React apps: `@sodax/wallet-sdk-react`

The React package wraps each chain family’s native wallet SDK (wagmi for EVM networks, including LightLink) behind a uniform connector interface with a single persisted store.

pnpm add @sodax/wallet-sdk-react

Mount the provider with the chains you serve. LightLink is an entry under EVM, alongside any other EVM network you support:

import { SodaxWalletProvider, type SodaxWalletConfig } from '@sodax/wallet-sdk-react';
import { ChainKeys } from '@sodax/types';

const config: SodaxWalletConfig = {
  EVM: {
    chains: {
      [ChainKeys.LIGHTLINK_MAINNET]: { rpcUrl: 'https://replicator.phoenix.lightlink.io/rpc/v1' },
      [ChainKeys.SONIC_MAINNET]: { rpcUrl: 'https://rpc.soniclabs.com' },
    },
  },
};

Then connect and read accounts with the same three hooks for every chain family:

import { useXConnectors, useXConnect, useXAccount } from '@sodax/wallet-sdk-react';

function EvmConnect() {
  const connectors = useXConnectors({ xChainType: 'EVM' }); // MetaMask, Rabby, ...
  const { mutateAsync: connect } = useXConnect();
  const account = useXAccount({ xChainType: 'EVM' });

  if (account.address) return <p>Connected: {account.address}</p>;

  return connectors.map(c => (
    <button key={c.id} onClick={() => connect(c)}>{c.name}</button>
  ));
}

One EVM connection covers every EVM network, so the wallet may be on a different network than LightLink when your user acts. useEvmSwitchChain({ xChainId: ChainKeys.LIGHTLINK_MAINNET }) returns isWrongChain and a handleSwitchChain callback to prompt the switch.

Bridging to SDK calls

useWalletProvider({ xChainId: ChainKeys.LIGHTLINK_MAINNET }) returns a typed IEvmWalletProvider ready to pass into any @sodax/sdk method. The swap and money market calls take it directly.

Scripts and backends: `EvmWalletProvider`

Outside React, construct the provider from @sodax/wallet-sdk-core directly:

import { EvmWalletProvider } from '@sodax/wallet-sdk-core';
import { ChainKeys } from '@sodax/sdk';

const walletProvider = new EvmWalletProvider({
  privateKey: '0x…', // private key of the LightLink account
  chainId: ChainKeys.LIGHTLINK_MAINNET,
  rpcUrl: 'https://replicator.phoenix.lightlink.io/rpc/v1',
});

EvmWalletDefaults lets you tune behavior per provider: sendTransaction, waitForTransactionReceipt, publicClient, walletClient, and transport.
