# Overview

FrostFS-Contract contains all FrostFS related contracts written for
[neo-go](https://github.com/nspcc-dev/neo-go) compiler. These contracts
are deployed both in the mainchain and the sidechain.

Mainchain contracts:

- frostfs
- processing

Sidechain contracts:

- alphabet
- audit
- balance
- container
- frostfsid
- netmap
- nns
- proxy
- reputation

# Getting started 

## Prerequisites

To compile smart contracts you need:

-   [neo-go](https://github.com/nspcc-dev/neo-go) >= 0.99.2

## Compilation

To build and compile smart contract, run `make all` command. Compiled contracts
`*_contract.nef` and manifest `config.json` files are placed in the 
corresponding directories. 

```
$ make all
/home/user/go/bin/cli contract compile -i alphabet -c alphabet/config.yml -m alphabet/config.json -o alphabet/alphabet_contract.nef
/home/user/go/bin/cli contract compile -i audit -c audit/config.yml -m audit/config.json -o audit/audit_contract.nef
/home/user/go/bin/cli contract compile -i balance -c balance/config.yml -m balance/config.json -o balance/balance_contract.nef
/home/user/go/bin/cli contract compile -i container -c container/config.yml -m container/config.json -o container/container_contract.nef
/home/user/go/bin/cli contract compile -i frostfsid -c frostfsid/config.yml -m frostfsid/config.json -o frostfsid/frostfsid_contract.nef
/home/user/go/bin/cli contract compile -i netmap -c netmap/config.yml -m netmap/config.json -o netmap/netmap_contract.nef
/home/user/go/bin/cli contract compile -i proxy -c proxy/config.yml -m proxy/config.json -o proxy/proxy_contract.nef
/home/user/go/bin/cli contract compile -i reputation -c reputation/config.yml -m reputation/config.json -o reputation/reputation_contract.nef
/home/user/go/bin/cli contract compile -i nns -c nns/config.yml -m nns/config.json -o nns/nns_contract.nef
/home/user/go/bin/cli contract compile -i frostfs -c frostfs/config.yml -m frostfs/config.json -o frostfs/frostfs_contract.nef
/home/user/go/bin/cli contract compile -i processing -c processing/config.yml -m processing/config.json -o processing/processing_contract.nef
```

You can specify path to the `neo-go` binary with `NEOGO` environment variable:

```
$ NEOGO=/home/user/neo-go/bin/neo-go make all
```

Remove compiled files with `make clean` or `make mr_proper` command.

## Building Debian package

To build Debian package containing compiled contracts, run `make debpackage`
command. Package will install compiled contracts `*_contract.nef` and manifest 
`config.json` with corresponding directories to `/var/lib/neofs/contract` for 
further usage.
It will download and build neo-go, if needed.

To clean package-related files, use `make debclean`.

# Testing
Smartcontract tests reside in `tests/` directory. To execute test suite
after applying changes, simply run `make test`.
```
$ make test
ok      git.frostfs.info/TrueCloudLab/frostfs-contract/tests       0.462s
```
