NeoFS related smart contracts.

---

Overview

neofs-contract contains all NeoFS-related contracts written for neo-go compiler. There are contracts both for the main and FS chains.

Main chain (mainnet) contracts:

• neofs
• processing

FS chain contracts:

• alphabet
• balance
• container
• netmap
• nns
• proxy
• reputation

Getting started

Compilation

To build and compile smart contract, run make all command. Compiled contracts contract.nef and manifest manifest.json files are placed in the corresponding directories. Generated RPC binding files rpcbinding.go are placed in the corresponding rpc directories.

$ make all
/home/user/go/bin/cli contract compile -i contracts/alphabet -c contracts/alphabet/config.yml -m contracts/alphabet/manifest.json -o contracts/alphabet/contract.nef --bindings contracts/alphabet/bindings_config.yml
mkdir -p rpc/alphabet
/home/user/go/bin/cli contract generate-rpcwrapper -o rpc/alphabet/rpcbinding.go -m contracts/alphabet/manifest.json --config contracts/alphabet/bindings_config.yml
...

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 command.

Building Debian package

To build Debian package containing compiled contracts, run make debpackage command. Package will install compiled contracts contract.nef and manifest manifest.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      github.com/nspcc-dev/neofs-contract/tests       0.462s

Comparing contracts content of NeoFS chains

scripts directory contains CLI utilities to compare some of the NeoFS contract contents between two RPC nodes:

• compare-fscontent performs comparison of container blobs and NetMap contract entries.
• compare-deposits performs comparison of mainnet deposits and FS chain balance mints.
