Hi there! This is our regular development report and new version of the platform is 0.8.0. See full changelog.

• New smart contract constructor: Crowdfunding for ERC20 token. Easily raise Ether funds for your startup in exchange for your ERC20 tokens! Just share the contract instance link to your potential contributors.
• Added freeze function to the Multisignature Wallet constructor.
• Now third-party developers can open public access to the dashboard of deployed contracts (not even verified).
• Access to the contract dashboard is now available without authorization.
• Widgets, input field: added option to define the algorithm in stringHash, avaliable keccak256 (by default) or sha256:

// constructor.py — get_params — ui_schema from returned dictionary
"stringHashSha256": {
 "ui:widget": "stringHash",
 "ui:options": {
 "algorithm": "sha256"
 }
},

And in the input field for parameter of the calling function:

// constructor.py — post_construct — function_specs from returned dictionary
..
'inputs': [
 {
 'title': 'string hash',
 'description': 'Hash of string will be sent as param to smart contract function',
 'ui:widget': 'stringHash',
 "ui:options": {
 "algorithm": "sha256"
 }
 }
]
..

• If the contract has a fallback function that receive Ether, then there is a button for sending Ether to the contract in the dashboard section with write functions. Text and description of this field can be customized by specifying in the function specification:

// constructor.py — post_construct — function_specs from returned dictionary
'': {
 'title': 'Send ether to contract (fallback)',
 'description': 'Send ether to contract (fallback description)',
 'sorting_order': 1,
 'payable_details': {
 'title': 'Ether amount (custom)',
 'description': 'This ether amount will be sent to the contract (custom)'
 }
},

• Added ability to specify the amount of sent Ether when calling payable functions. Text and description of this field can be customized as well as fallback function:

// constructor.py — post_construct — function_specs from returned dictionary
'sendEther': { # payable function name
 'title': 'Send ether to contract',
 'description': 'Payable function. Ether amount can be set',
 'sorting_order': 200,
 'payable_details': {
