Hedera™ Hashgraph Go SDK

The Go SDK for interacting with Hedera Hashgraph: the official distributed consensus platform built using the hashgraph consensus algorithm for fast, fair and secure transactions. Hedera enables and empowers developers to build an entirely new class of decentralized applications.

Hedera Hashgraph communicates using gRPC; the Protobufs definitions for the protocol are available in the hashgraph/hedera-protobuf repository.

Install

$ go get github.com/hashgraph/hedera-sdk-go/v2

Note

google.golang.org/protobuf v1.27.1 Breaks the SDK as it contains multiple protobuf files with the same name. Make sure to use v1.26.1 instead. The follow snippet can be used in go.mod to force the project to use v1.26.1

replace (
	google.golang.org/protobuf v1.27.1 => google.golang.org/protobuf v1.26.1-0.20210525005349-febffdd88e85
)

Running Integration Tests

$ env CONFIG_FILE="<your_config_file>" go test -v Integration -timeout 9999s ```

or

```bash
$ env CONFIG_FILE="<your_config_file>" OPERATOR_KEY="<key>" OPERATOR_ID="<id>" go test -v Integration -timeout 9999s

or

$ env OPERATOR_KEY="<key>" OPERATOR_ID="<id>" go test -v Integration -timeout 9999s

The config file can contain both the network and the operator, but you can also use environment variables OPERATOR_KEY and OPERATOR_ID. If both are provided the network is used from the config file, but for the operator the environment variables take precedence. If the config file is not provided then the network will default to testnet and OPERATOR_KEY and OPERATOR_ID must be provided.
