- When parsing opts, opts.init() now looks only at string values from
opts_data. Global variables are evaluated only when printing help text,
after the variables are initialized
This is a work in progress. Currently, basic operations for BTC and ETH are
supported.
The successor to the MinGW64 project, MSYS2 features package management via
`pacman` and support for Python 3:
https://sourceforge.net/projects/msys2https://www.msys2.org
The rationale for this patch is similar to that of commit a7126ed:
- Many packages were imported for the sake of just a few trivial conversion
functions. These functions have been copied into the local pyethereum.utils.
- rlp has been locally copied and its import statements modified to import
the locally-copied functions. Unneeded classes and functions have been
removed.
- As a result, dependencies on the following external packages have been
eliminated:
+ rlp
+ eth-hash
+ eth-utils
+ eth-typing
+ toolz
+ cytoolz
+ setuptools
- pysha3: Monero and Ethereum use the old pre-SHA3 version of the keccak
hash function, which is not supported by hashlib.sha3.
The pysha3 package supports the function but is not portable.
Therefore, use the pure-Python implementation mmgen.keccak as a fallback,
making the pysha3 package optional.
Use of mmgen.keccak may be forced with --use-internal-keccak-module
mmgen.keccak was ported from the Python 2 implementation at
https://github.com/ctz/keccak
- ethereum (pyethereum): Installation of this package presents numerous
problems due to poor maintenance and many superfluous dependencies.
Therefore, use stripped-down and modified local versions of
ethereum.transactions and ethereum.utils as fallbacks, making the ethereum
package optional.
The local pyethereum.utils uses mmgen.keccak as a fallback for pysha3's
keccak implementation.
tooltest.py - bugfixes, remove some commands covered in tooltest2.py
mmgen-tool - bugfixes, cleanups, rename some commands, change some command
options
- all commands taking binary input can now receive it from file
or stdin
+ numerous minor fixes throughout
- test groups are now separate classes in separate modules
- test data and code is loaded on an as-needed basis
- new TestSuiteRunner and CmdGroupMgr classes
- simplified invocation: if arguments are omitted, all default tests relevant
for given network and option are run. The following set of invocations
provides nearly complete coverage of MMGen's core functionality:
test/test.py
test/test.py --segwit-random
test/test.py --bech32
test/test.py --coin=ltc
test/test.py --coin=ltc --segwit-random
test/test.py --coin=ltc --bech32
test/test.py --coin=bch
test/test.py --coin=eth
test/test.py --coin=etc
- 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
