sgxwallet is a next generation hardware secure crypto wallet that is based on Intel SGX technology. It currently supports Ethereum and SKALE, and will support Bitcoin in the future.
sgxwallet runs as a network server. Clients connect to the server, authenticate to it using TLS 1.0 protocol with client certificates, and then issue requests to the server to generate crypto keys and perform cryptographic operations. The keys are generated inside the secure SGX enclave and never leave the enclave unencrypted.
The server provides an initial registration service to issue client certificates to the clients. The administrator manually approves each registration.
sgxwallet has been tested on Ubuntu Linux 20.04.
The sgxwallet server is still in active development and therefore should be regarded as alpha software. The development is still subject to security hardening, further testing, and breaking changes. This server has not yet been reviewed or audited for security. Please see SECURITY.md for reporting policies.
As you probably suspect, the first thing to do is to clone this repository and all it is sub-repositories.
git clone https://github.com/skalenetwork/sgxwallet.git --recurse-submodulesThe easiest way to try the sgxwallet server is to run a docker container in insecure simulation mode that emulates an SGX processor. Once you are familiar with the server, you can enable sgx on your machine and run it in secure production mode.
First install docker-compose if you dont have it
sudo apt-get install docker.io docker-composeThen run sgxwallet using docker-compose
cd run_sgx_sim; sudo docker-compose upNote: you need a machine that supports Intel AVX512 instruction set. Most modern Intel CPUs support it. To verify you machine supports AVX512, run
cat /proc/cpuinfo | grep avx512
Note: sgxwallet requires docker-compose for correct operation. You must always use docker-compose and avoid using raw docker tools.
Note: simulation mode is only to try sgxwallet. In production, you need to run sgxwallet on a server that supports SGX. Never run a production sgxserver in simulation mode.
If you are a SKALE validator and want to run sgxwallet for testnet or mainnet usage, you need
a SGX-capable server.
Please refer to Admin guide for details on how to setup sgxwallet in a secure hardware mode

If you are a SKALE developer and want to build sgxwallet from source, please refer to Developer guide docs/developer-guide.md.
