await controller.getExchangeRate({ toContractAddress, toContractDecimal, fromContractAddress, fromContractDecimal, fromQuantity, slippageTolerance, walletAddress })

Get Estimated gas

This will give us the estimated amount of gas needed to do the swap.

await controller.getEstimatedGas({ toContractAddress, toContractDecimal, fromContractAddress, fromContractDecimal, fromQuantity, slippageTolerance, walletAddress })

This will give us the raw transaction to swap the tokens on pancakeswap.

await controller.getRawTransaction({ walletAddress, toContractAddress, toContractDecimal, fromContractAddress, fromContractDecimal, toQuantity, fromQuantity, slippageTolerance })

Get Approval Transaction

This function will call the approval smart contract function to approve spending fromQuantity for the fromContractAddress from the walletAddress.

await controller.approvalRawTransaction({ fromContractAddress, walletAddress, fromQuantity })
