XRC20 Token Integration

How to call functions in Go SDK?

CreateAccount() → string Returns the Private Key.

CheckAddress(Private_key string) → string Returns the Address User.

Name(Token_address string) → string Returns the name of the token.

Symbol(Token_address string) → string Returns the symbol of the token, usually a shorter version of the name.

Decimals(Token_address string) → uint8 Returns the number of decimals used to get its user representation. For example, if decimals equal 2, a balance of 505 tokens should be displayed to a user as 5,05 (505 / 10 ** 2).

Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei.

Total_supply(Token_address string) → string Returns the number of tokens in existence.

BalanceOf(Token_address string ,Owner_address string) → string Returns the number of tokens owned by the account.

Allowance(Token_address string , Owner_address string , Spender_address string) → string Returns the remaining number of tokens that the spender will be allowed to spend on behalf of the owner through transferFrom. It is zero by default.

Approve_(Private_key string, Token_address string,sender_address string,Gas_Price string,Gas_Limit string,Amount string) -> string Pass Private key, Token address, Spender address, Gas Price, Gas Limit. It will return a transaction hash.

XDCTransfer(Private_key string, To_Address string, Value_ string,gasLimit uint64) -> string Moves XDC from the caller’s account to recipient. It will return a transaction hash.

TokenTransfer_(Private_key string, Token_address string, sender_address string,Gas_Price string, Gas_Limit string,Tokens_ string) -> string Moves tokens from the caller’s account to the recipient. It will return a transaction hash.

FromTransfer_(Private_key string, Token_address string,sender_address string,Gas_Price string,Gas_Limit string,Amount string) -> string Pass Private key, Token address, Spender address, Gas Price, Gas Limit and Amount. It will return a transaction hash.

IncreaseAllowance_(Private_key string, Token_address string,sender_address string,Gas_Price string,Gas_Limit string,Amount string) -> string Automatically increases the allowance granted to spender by the caller.

DecreaseAllowance_(Private_key string,Token_address string,sender_address string,Gas_Price string, Gas_Limit string, Amount string) -> string Automatically decreases the allowance granted to spender by the caller.

Example to call functions in Go SDK

Step 1: Clone git repo (go-xdc) in any folder and copy it.

Step 2: Go to that directory where your Golang saves. (go to your go folder).

Step 3: Find SRC in your go folder.

Step 4: Open SRC Folder and pasted your go-xdc.

Use like this in your main package.

package main
import(
	"go-xdc/xdcsdk"
	"fmt"
)
func main(){
	Private_key := "8a32103448a851b2fed3e95d2b4fbaa5e564f3b8cc42eac0d3be15a96311f355"
	Token_address := "0xba9d6a36fbc194f5d1aa48a2892ae4bdf6939cb9"
	Owner_address := "0xd7813e7cfdf83d6fa3469d7411b52a50ed2b867f"
	Spender_address := "0xedb472070566e072f3bdaa50cfa076e772135f33"
	Gas_limit :="3000000"
	Gas_Price:= "3500000"
	var Gaslimit_In_Uint uint64
	Gaslimit_In_Uint=3000000

// for account creation
CreateAccount1:=xdcsdk.CreateAccount()
fmt.Println("CreateAccount Private key :",CreateAccount1)

// for check address
CheckAddress1:=xdcsdk.CheckAddress(CreateAccount1)
fmt.Println("User Address :",CheckAddress1)

// for Name
Name1:=xdcsdk.Name(Token_address)
fmt.Println("name :",Name1)

// for Symbol
Symbol1:=xdcsdk.Symbol(Token_address)
fmt.Println("symbol: ",Symbol1)

// for decimal
Decimals1:=xdcsdk.Decimals(Token_address)
fmt.Println("Decimals: ",Decimals1)

// for totalsupply
Total_supply1:=xdcsdk.Total_supply(Token_address)
fmt.Println("Total_supply: ",Total_supply1)

// for Balanceoff
BalanceOf1:=xdcsdk.BalanceOf(Token_address,Owner_address)
fmt.Println("BalanceOf: ",BalanceOf1)

// for Allowance
Allowance1:=xdcsdk.Allowance(Token_address,Owner_address,Spender_address)
fmt.Println("Allowance: ",Allowance1)

// for Approve
Approve_1:=xdcsdk.Approve_(Private_key,Token_address,Spender_address,Gas_Price,Gas_limit,"3")
fmt.Println("Approve_: ",Approve_1)

// for XDC Transfer
XDCTransfer1:=xdcsdk.XDCTransfer(Private_key,Spender_address,"1",Gaslimit_In_Uint)
fmt.Println("XDCTransfer: ",XDCTransfer1)

// for Token Transfer
TokenTransfer_1:=xdcsdk.TokenTransfer_(Private_key,Token_address,Spender_address,Gas_Price,Gas_limit,"5")
fmt.Println("TokenTransfer_: ",TokenTransfer_1)

// for From Transfer
FromTransfer_1:=xdcsdk.FromTransfer_(Private_key,Token_address,Spender_address,Gas_Price,Gas_limit,"1")
fmt.Println("FromTransfer_: ",FromTransfer_1)

// for Increase Allowance
IncreaseAllowance_1:=xdcsdk.IncreaseAllowance_(Private_key,Token_address,Spender_address,Gas_Price,Gas_limit,"1")
fmt.Println("IncreaseAllowance_1: ",IncreaseAllowance_1)

// for Decrease Allowance
DecreaseAllowance_1:=xdcsdk.DecreaseAllowance_(Private_key,Token_address,Spender_address,Gas_Price,Gas_limit,"1")
fmt.Println("DecreaseAllowance_: ",DecreaseAllowance_1)

}

XRC721 Token Integration
