- group tool commands into classes
- add docstrings to command classes and methods
- annotate command method args
- generate call signatures + help and usage screens on the fly
- API changes:
- listaddresses,twview: new 'age_fmt' option replaces 'show_days' and 'show_age'
- addrfile_chksum and friends: 'mmtype' option removed
- tooltest.py, tooltest2.py and test.py have been updated accordingly
This is the first commit of the MMGen Python 3 port. Branch 'py3port', against
master branch commit ab06ca4
Commits are groupings of similar or related changes: automatic changes first,
followed by repetitive and global changes, followed by specific ones
All commits until the final one will leave the branch in a broken state
As with ETH transacting support, this feature is in beta phase
All key functionality works, for both ETC and ETC tokens:
- Tracking wallet: getbalance, twview, listaddresses
- TX create, send, sign
- TX bumping
- ERC20 token creation, deployment
For usage details, see https://github.com/mmgen/mmgen/wiki/Altcoin-and-Forkcoin-Support
Differences from ETH:
- Start Parity with --jsonrpc-port=8555 (or --ports-shift=10) and --chain=classic
- Launch MMGen commands with --coin=etc
This feature is EXPERIMENTAL. Until v0.9.9 is released, mainnet use is
strictly at your own risk!
To test on dev chain, run 'test/test.py -e ethdev'
To test on Kovan, add '--testnet=1' option to all commands below
Transaction example:
Generate some ETH addresses with your default wallet:
$ mmgen-addrgen --coin=eth 1-5
Create an EOS token tracking wallet and import the addresses into it:
$ mmgen-addrimport --coin=eth --token=86fa049857e0209aa7d9e616f7eb3b3b78ecfdb0 ABCDABCD-ETH[1-5].addrs
Send 10+ EOS from an exchange or another wallet to address ABCDABCD:E:1
Create a TX sending 10 EOS to address aabbccdd..., with change to ABCDABCD:E:2:
$ mmgen-txcreate --coin=eth --token=eos aabbccddaabbccddaabbccddaabbccddaabbccdd,10 ABCDABCD:E:2
On your offline machine, sign the TX:
$ mmgen-txsign --coin=eth --token=eos ABC123-EOS[10,50000].rawtx
On your online machine, send the TX:
$ mmgen-txsend --coin=eth --token=eos ABC123-EOS[10,50000].sigtx
View your EOS tracking wallet:
$ mmgen-tool --coin=eth --token=eos twview
Token creation/deployment example:
Install the Solidity compiler ('solc') on your system.
Create a token 'MFT' with default parameters, owned by ddeeff... (ABCDABCD:E:1):
$ scripts/create-token.py --symbol=MFT --name='My First Token' ddeeffddeeffddeeffddeeffddeeffddeeffddee
Deploy the token on the ETH blockchain:
$ mmgen-txdo --coin=eth --tx-gas=200000 --contract-data=SafeMath.bin
$ mmgen-txdo --coin=eth --tx-gas=250000 --contract-data=Owned.bin
$ mmgen-txdo --coin=eth --tx-gas=1100000 --contract-data=Token.bin
...
Token address: abcd1234abcd1234abcd1234abcd1234abcd1234
Create an MFT token tracking wallet and import your ETH addresses into it:
$ mmgen-addrimport --coin=eth --token=abcd1234abcd1234abcd1234abcd1234abcd1234 ABCDABCD-ETH[1-5].addrs
View your MFT tracking wallet:
$ mmgen-tool --coin=eth --token=mft twview
Versions of MMGen prior to 0.9.7 were vulnerable to an attack whereby a
compromised MMGen installation on the network-connected machine could trick
an offline installation into revealing the user's seed via a specially crafted
transaction file.
Since sufficient time has passed for users to upgrade, we now deem it safe to
publish the exploit, implemented as a patch against v0.9.6. Instructions for
use are in the patch itself.
- This commit introduces a backwards incompatibility. Users with non-UTF-8
brainwallets (if there are any, which is very unlikely) must export them to
another MMGen wallet format using an older version of MMGen.
- closes an exploit whereby an infected online MMGen installation could craft
a special TX file to trick an offline signing MMGen into executing an
arbitrary expression
- update TX file format (to v3) to permit calling literal_eval() on unmodified
inputs and outputs data (old v2 file format continues to be supported)
- new TX file conversion script: `scripts/tx-v2-to-v3.py`
- `scripts/tx-old2new.py` modified and renamed to `scripts/tx-v1-to-v3.py`
