Alphabill Wallet

Client side software to interface with Alphabill network. This repository contains the following components:

• Money partition CLI wallet
• User Token partition CLI wallet
• EVM partition client

Update Alphabill dependency

go get github.com/alphabill-org/alphabill@<commit-id>

Building the source

• Requires golang version 1.21. (https://go.dev/doc/install)
• Requires C compiler, recent versions of GCC are recommended. In Debian and Ubuntu repositories, GCC is part of the build-essential package. On macOS, GCC can be installed with Homebrew.

Run make build to build the application. Executable will be built to build/abwallet.

Configuration

It's possible to define the configuration values from (in the order of precedence):

• Command line flags (e.g. --address="/ip4/127.0.0.1/tcp/26652")
• Environment (Prefix 'AB' must be used. E.g. AB_ADDRESS="/ip4/127.0.0.1/tcp/26652")
• Configuration file (properties file) (E.g. address="/ip4/127.0.0.1/tcp/26652")
• Default values

The default location of configuration file is $AB_HOME/config.props

The default $AB_HOME is $HOME/.alphabill

Logging configuration

Logging can be configured through a yaml configuration file. See cli/alphabill/config/logger-config.yaml for example.

Default location of the logger configuration file is $AB_HOME/logger-config.yaml

The location can be changed through --logger-config configuration key. If it's relative URL, then it's relative to $AB_HOME. Some logging related parameters can be set via command line parameters too - run alphabill -h for more.

Tracing tests

To enable trace exporter for test the AB_TEST_TRACER environment variable has to be set to desired exporter name, ie

AB_TEST_TRACER=otlptracehttp go test ./...

The test tracing will pick up the same OTEL environment variables linked above except that some parameters are already "hardcoded":

• "always_on" sampler is used (OTEL_TRACES_SAMPLER);
• the otlptracehttp exporter is created with "insecure client transport" (OTEL_EXPORTER_OTLP_INSECURE);

Tracing wallet commands

It is possible to collect traces from wallet command by setting the AB_TRACING and OTEL_EXPORTER_OTLP_ENDPOINT environment variables, ie:

AB_TRACING=otlptracehttp OTEL_EXPORTER_OTLP_ENDPOINT=https://apmserver.abdev1.guardtime.com alphabill wallet ...

will send the traces into the devnet APM backend.

CI setup

See gitlab-ci.yml for details.

GitLab runs the CI job inside docker container defined in alphabill/gitlab-ci-image.
