    exchange.IO("key", "Private Key")
}

Arguments

Name	Type	Required	Description
k	string	Yes	Function of `exchange.IO()`. When set to `key`, it indicates that the function is used to switch private keys.
key	string	Yes	Private key string.

Remarks

The exchange.IO() function supports private key switching functionality, allowing operations on multiple wallet addresses. You can also add multiple exchange objects (refer to: exchanges) to operate multiple wallet addresses.

For private key switching operations: exchange.IO("key", "xxx"), concurrent switching is not supported.

The private key is a hex string with an optional 0x prefix. An invalid key is reported as an error and nothing is switched. The key is only kept in memory and never written to the log; after switching, getting the address, signing and sending transactions all use the new key.
