An OTP Wallet Client
This is an experimental keyless crytpo wallet client for OTP proxies on the ETF Network.
This client allows users to authenticate with a pure proxy by using an OTP code. It uses timelock encryption and time-based OTP generation
cargo build
cargo test
In order to use the wallet, there must be at least one node running. I recommend running a local node for testing purposes.
Also, the OTP wallet can only be called via proxy, so in order to use this client you must also have an ETF wallet somewhere. This could be through the polkadotjs extension or in the local keystore.
- first build the project (cargo build) to generate the target/debug folder, where otp-wallet-client exists. Alternately, building in release mode will generate the target/release folder.
otp-wallet-client new <name> <seed> This writes to a new file called mmr_store in the root directory. This file contains the MMR leaf data. It is not secret data and can be freely publicized or broadcast (e.g. it can be stored in IPFS without exposing any secret information).
- Use the seed to generate a new TOTP generator
- Based on the current block number and the max block height parameter, generate future OTP codes for each future block in the range
- Build an MMR
- Call the
OTPProxy > createextrinsic with the MMR root to create the proxy [TODO]
- delay must be >= 2
- assumes mmr_store exists in root
otp-wallet-client execute <name> <seed> --delay 2 --to AcctId --amount 100_000_00# clone and build the node
git clone [email protected]:ideal-lab5/etf.git
cd etf
cargo +stable build
# run a local node
./target/debug/node --tmp --dev --alice --unsafe-rpc-external --rpc-cors all
# use subxt to prepare metadata
cd /path/to/otp-wallet/
mkdir artifacts
cargo install subxt-cli
# Download and save all of the metadata:
subxt metadata > ./artifacts/metadata.scale- pass mmr_store path as a parameter
- error handling
- add dry run option (e.g. to check if username is a duplicate) e.g. add the '-x' flag to indicate if the call should be executed:
otp-wallet-client execute ... -x - modify cli to allow any call to be submitted, something like
otp-wallet-client execute <username> <seed> --pallet <pallet_name> --extrinsic <extrinsic name> --params [path separated parameter list] --delay X
