This is a bare bones CLI written in rust for ERC-5564 compliant stealth address management on evm chains
It's currently the easiest way to interact with the eth-stealth-addresses rust library which implements the basic cryptographic operations necessary for a stealth addresses scheme over the secp256k1 curve (with view tags) as outlined here
For now it's extremely rough and low level! More improvements soon
cargo install stealthereum-cli
Make sure you add $HOME/.cargo/bin to your PATH
generate a stealth meta address and store the keys
bash
stealthereum keygen -o path/to/keyfile.json
recompute your stealth meta address from keyfile
bash
stealthereum show-meta-addr -k path/to/keyfile.json
generate all the components of a stealth transaction as defined in ERC-5564 given a target receiver and the desired asset(s) to sealthily transfer
bash
stealthereum stealth-tx -r 0xReceiverStealthMetaAddres --msgvalue 1000000000000000000 --tokens 0x12970E6868f88f6557B76120662c1B3E50A646bf 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 --amounts 1 100000000
the above example would output: 1. a stealth address 2. an ephemeral public key and 3. metadata for stealthily transferring (on mainnet) 1 ETH, a Milady (tokenId=1), and 100 USDC to the owner of the stealth meta address.
compute the private key for a stealth address you control
bash
stealthereum reveal-stealth-key -k path/to/keyfile.json -s 0xSomeStealthAddress -e 0xSomeEphemeralPubkey
note that this requires you to know in advance what [stealth_address, ephemeral_pubkey] pairs are actually payments meant for your stealth meta address. To find this out see scan command below.
scan announced stealth transfers for payments to your stealth meta address
bash
stealthereum scan -k path/to/keyfile.json -s path/to/scanfile.json
this will log the [stealth_address, ephemeral_pubkey] pairs of all stealth transfers that are claimable by you in the scanfile.
For now a scanfile has to be precomputed into a JSON format like so
json
{
"announcements": [
{
"stealth_address": "0xSomeStealthAddress",
"ephemeral_pubkey": "0xSomeEphemeralPubkey",
"view_tag": 116
},
{
"stealth_address": "0xSomeOtherAddress",
"ephemeral_pubkey": "0xSomeOtherPubkey",
"view_tag": 94
}
]
}
