Network Switching

Cosmostation’s Bitcoin provider lets your dApp read the currently selected Bitcoin network and request a network switch (e.g. mainnet, signet) through the wallet UI.

This is useful when you support multiple environments (production vs test flows), or when your dApp needs to ensure the user is connected to the correct network before:

  • creating / signing PSBTs
  • pushing a raw transaction
  • showing UTXOs and balances
  • generating a receive address (prefix differs per network)

SDK Integration (Tomo Wallet SDK)

In a React app using @tomo-inc/wallet-connect-sdk, you typically access the provider via useTomoProviders() and call getNetwork() / switchNetwork().

Get current network

<LodingButton
  disabled={!btcIsConnect}
  onClick={async () => {
    try {
      const result = await providers.bitcoinProvider?.getNetwork();
      console.log('btc getNetwork', result);
      setTestGetNetwork(result || '');
    } catch (e) {
      console.log(e);
    }
  }}
>
  btc getNetwork()
</LodingButton>

Switch network (MAINNET / SIGNET)

<LodingButton
  disabled={!btcIsConnect}
  onClick={async () => {
    try {
      await providers.bitcoinProvider?.switchNetwork(Network.MAINNET);
      setTestSwitchNetwork('mainnet');
    } catch (e) {
      console.log(e);
    }
  }}
>
  btc switchNetworkToMain()
</LodingButton>
 
<LodingButton
  disabled={!btcIsConnect}
  onClick={async () => {
    try {
      await providers.bitcoinProvider?.switchNetwork(Network.SIGNET);
      setTestSwitchNetwork('signet');
    } catch (e) {
      console.log(e);
    }
  }}
>
  btc switchNetworkToSignet()
</LodingButton>

Vanilla JavaScript Integration

If you are calling the injected provider directly, the flow is the same.

const bitcoin = () => {
  if ('cosmostation' in window) return window.cosmostation.bitcoin;
  window.open('https://cosmostation.io/wallet/#extension');
};
 
const provider = bitcoin();
 
await provider.connectWallet();
 
// 1) read current network
const current = await provider.getNetwork();
console.log('current network:', current);
 
// 2) request switch (example: 'signet')
await provider.switchNetwork('signet');
 
// 3) refresh state after switching
const address = await provider.getAddress();
const balance = await provider.getBalance();
console.log('address after switch:', address);
console.log('balance after switch:', balance);

Tip: After switching networks, always refresh any cached values in your app UI (address, balance, UTXOs, inscriptions), because they are network-dependent.
