I'm currently use this package to generate new transaction in ETH:
Now I want to generate a transaction for an ERC20 token like Tether. As I know when we want to create an eth transaction we have to set all of these items :
nonce' => $this->nonce, 'gasPrice' => $this->gasPrice, 'gasLimit' => $this->gasLimit, 'to' => $this->to, 'value' => $this->value, 'data' => $this->data, 'v' => $this->v, 'r' => $this->r, 's' => $this->s,
But I don't have any idea about tokens, are they same as ETH transaction? How and where we defined this transaction is about token and which token?
