Note : mpc is considered beta software. We make no warranties or guarantees of its security or stability.

Install the Docker version

1. Install Docker. This depends on your platform, on Ubuntu this works:

sudo apt update
sudo apt install docker.io

2. Download the Docker image and create and run the container:

• bootnode

docker run -d --name bootnode --network host --restart always -v /var/lib/docker/bootnode:/bootnode anyswap/bootnode --addr :48447

• mpcnode

docker run -d --name mpcnode --network host --restart always -v /var/lib/docker/mpcnode:/mpcnode anyswap/anympcnode

default: rpcport 8449, port 8441 bootnodes enode://cdefe85532587f6ee0bbc29790aca7d54bf633b9fc19c991fe9af1b67284460d586928003a6af69c210fba8a1cce9f009a37d695382e34034b10d05b3df3ac8f@47.88.26.170:48447

• mpcnode-client

docker exec mpcnode mpcnode-client --cmd ACCEPTREQADDR --url http://127.0.0.1:8449 --keystore keystore --passwd "123456" --key 0x...

Install the Source version

Prerequisites

1. VPS server with 1 CPU and 2G mem
2. Static public IP
3. Golang ^1.12

Setting Up

Clone The Repository

To get started, launch your terminal and download the latest version of the SDK.

mkdir -p $GOPATH/src/github.com/fsn-dev

cd $GOPATH/src/github.com/fsn-dev

git clone https://github.com/fsn-dev/dcrm-walletService.git

Build

Next compile the code. Make sure you are in dcrm-walletService directory.

cd dcrm-walletService && make

Run

First generate the node key:

./bin/cmd/gdcrm --genkey node1.key

then run the dcrm node 7x24 in the background:

nohup ./bin/cmd/gdcrm --nodekey node1.key &

The gdcrm will provide rpc service, the default RPC port is port 4449.

Note: Before use walletService RPC API, please wait at least 5 minutes after running the node which need to prepare dcrm env.

Front-end

After running the dcrm wallet rpc service and get the rpc IP:port, we can use SMPCWallet to connect the rpc service. This front-end can create distributed custodial account which support BTC/ETH/FSN.
