* Added more sync objects to avoid accidental data races * made lib.config.Config variables are private, so they cannot be tampered with (multithreading). Please introduce Get-methods to retrieve the varialbes outside of the package if you need it. This way, the race conditions and unexpected change of the global object state can be protected * added reverse takedown of the validators to avoid the following error [app] PoP broadcast tx failed: node0.info: key not found * moved util.TerminationWaitGroup.Wait() to the central network cleanup method * removed mappings for private variables Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com>
Library for RPC requests to Planetmint
How to use it
In the example below we use the account addr0 for which we have the private key in our keyring.
We configure the address prefix andd change the default RPC endpoint to a remote one.
The only keyring backend currently supported is the test backend under keyring-test.
After that we construct three messages to send 10plmnt each to three addresses addr1, addr2 and addr3.
We then build and sign the transaction and eventually send this transaction via RPC.
For debugging purposes we print the transaction that we send as JSON.
package main
import (
"fmt"
"log"
sdk "github.com/cosmos/cosmos-sdk/types"
banktypes "github.com/cosmos/cosmos-sdk/x/bank/types"

"github.com/planetmint/planetmint-go/lib"
)
func main() {
encodingConfig := app.MakeEncodingConfig()
libConfig := lib.GetConfig()
libConfig.SetEncodingConfig(encodingConfig)
libConfig.SetRPCEndpoint("https://testnet-rpc.rddl.io:443")
addr0 := sdk.MustAccAddressFromBech32("plmnt168z8fyyzap0nw75d4atv9ucr2ye60d57dzlzaf")

addr2 := sdk.MustAccAddressFromBech32("plmnt1pwquxvqmmdry4gdel4g4rz0js7jy65453h92g7")
addr3 := sdk.MustAccAddressFromBech32("plmnt1dyuhg8ldu3d6nvhrvzzemtc3893dys9v9lvdty")
coin := sdk.NewCoins(sdk.NewInt64Coin("plmnt", 10))
msg1 := banktypes.NewMsgSend(addr0, addr1, coin)
msg2 := banktypes.NewMsgSend(addr0, addr2, coin)
msg3 := banktypes.NewMsgSend(addr0, addr3, coin)
txJSON, err := lib.BuildUnsignedTx(addr0, msg1, msg2, msg3)
if err != nil {
log.Fatal(err)
}
fmt.Println(txJSON)
_, err = lib.BroadcastTxWithFileLock(addr0, msg1, msg2, msg3)
if err != nil {
log.Fatal(err)
