Switch Chain

Switch the blockchain network to another one


It supports Ethereum/EVMs/Layer2 injected at window.ethereum. Blocto follows eip-3326 and will not reload the webpage after switching the network.


// Switch to BSC
const params = [{ chainId: '0x38' }]
await window.ethereum.request({
  method: 'wallet_switchEthereumChain',
  params: params

Switching network will emit a chainChanged event.

window.ethereum.on('chainChanged', (chainId) => {
  console.log(chainId) // 0x38 if it's BSC
