@chapter Tools
|
|
|
|
|
|
When installed as a python package, @code{erc20-demurrage-token} installs the @code{erc20-demurrage-token-publish} executable script, which can be used to publish smart contract instances.
|
|
|
|
While the man page for the tool can be referred to for general information of the tool usage, two argument flags warrant special mention in the context of this documentation.
|
|
|
|
@table @code
|
|
@item --demurrage-level
|
|
The percentage of demurrage in terms of the redistribution period, defined as parts-per-million.
|
|
@item --redistribution-period
|
|
A numeric value denominated in @emph{minutes} to define the redistribution period of the voucher demurrage.
|
|
@end table
|
|
|
|
For example, to define a 2% demurrage value for a redistribution period of 30 days (43200 minutes), the argument to the argument flags would be:
|
|
|
|
@verbatim
|
|
erc20-demurrage-token-publish --demurrage-level 20000 --redistribution-period 43200 ...
|
|
@end verbatim
|
|
|
|
|
|
@section Calculating fixed-point values
|
|
|
|
The @code{erc20-demurrage-token} package installs the python package @code{dexif} as part of its dependencies.
|
|
|
|
This package in turn provides an epinymous command-line tool (@code{dexif}) which converts decimal values to a 128-bit fixed-point value expected by the contract constructor.
|
|
|
|
An example:
|
|
|
|
@example
|
|
$ dexif 123.456
|
|
7b74bc6a7ef9db23ff
|
|
|
|
$ dexif -x 7b74bc6a7ef9db23ff
|
|
123.456
|
|
@end example
|
|
|
|
|
|
@section Contract interaction with chainlib-eth
|
|
|
|
All smart contract tests are implementing using @url{https://git.defalsify.org/chainlib-eth, chainlib-eth} from the chaintool suite.
|
|
|
|
The @code{eth-encode} tool from the @code{chainlib-eth} python package may be a convenient way to interact with contract features.
|
|
|
|
Some examples include:
|
|
|
|
@example
|
|
# explicitly call changePeriod()
|
|
$ eth-encode --mode tx --signature changePeriod -e <contract_address> -y <key_file> ...
|
|
|
|
# Set the sink address seal (The integer value of the SINK_STATE flag is 2 at the time of writing)
|
|
$ eth-encode --mode tx --signature seal -e <contract_address> -y <key_file> ... u:2
|
|
|
|
# Query current sink address of contract
|
|
$ eth-encode --mode call --signature sinkAddress -e <contract_address> ...
|
|
@end example
