* [tests] Avoid potential data races * Revert "[lib] Switch from RPC (REST) to gRPC (#183)" This reverts commit db5f4fb3fe6899bcfdadf3471f826a6a97035440. * [lib] DRY: Use build and broadcast tx from cosmos-sdk This is in preparation for: https://github.com/rddl-network/issues/issues/46 Without this patch broadcasting a transaction in "offline mode" (setting the sequence number manually) would not work consistently. Every so often the endpoint would report back, that it got an unexpected sequence number. Executing the request with the same sequence number couple of seconds later would be successful. I decided to better use the same source code, that the CLI uses, because I know that offline mode works there. Signed-off-by: Julian Strobl <jmastr@mailbox.org>
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

"fmt"
"log"

coin := sdk.NewCoins(sdk.NewInt64Coin("plmnt", 10))
msg1 := banktypes.NewMsgSend(addr0, addr1, coin)
