Swift + Web3 (IOS App) Functionality for NFT TransferWe need a Swift Web3 JS developer to create the NFT Transfer functionality for our app. Currently, we have the FT Transfer which calls the transfer(to_adr,amount) now, we will need a similar view which executes the transferFrom(current_wal_adr, recieving_wal_adr, token_id) for the NFT likewise. We have the NFT Transfer models built, just no functionality yet. We are looking for a developer that is relatively comfortable with this task.
Swift Web 3 NFT Transfer (IOS App)We have a transfer page built into our wallet, we need the NFT transfer functionality added for this task (which triggers transferFrom() instead of transfer() from the tokens). And need to sign an NDA before doing this. Have other Swift Web3 related jobs later too.
Automatically Recognize a list of ERC721 collectibles In Trust Wallet IOS by Default \ Render #This is mostly a swift job. Ethereum, web3 knowledge may be required though. The task is to recognize the balance and name, of a list of ERC721 contracts by default in the Trust IOS wallet, if the wallet has any balance of collectibles show them. We will get the rest of the collectibles information from an API, but need this initial balance of ERC721s or collectibles to be rendered on mobile as a backbone (in case the API goes down for what ever reason). We will provide the ERC721 contract if needed. This is to be done for a fixed price. We need to set an image for the collectible based on the ERC721s name, this will end up being a predefined list as well.
Create Django REST Framework API to use web3 to ALL log ERC721s on the NetworkCreate Django Framework Restful API + using Web3JS that returns all ERC721 contracts information. Return the owner address of the ERC721, the token id, name, amount of uses remaining, and other essential fields the NFT needs in the Trust Wallet IOS to be rendered. This should query all ERC721s on our network. If it recognizes a new block to the node the API should automatically update the database (MongoDB) to include all 721 contracts info. Also add an image url field to each entry in the API or verify it is in the contract. We will provide the ERC721 contract later on. Looking to create an API similar to https://api.opensea.io/api/v1/assets/? . We want to be able to tie this API directly to our IOS Trust Wallet fork as a separate task. This task is to be done for a fixed price.
Guide on how to deploy & interact with Wyvern contracts & run Opensea-js on any given provider.I need a comprehensive guide made, on how to run Opensea-js ships log (front end) from any provider different than Ethereum. And instruction on how to point the ships-log collectible directory to the ERC721's on the given network. A specific document recording the necessary places to edit & modify the files + images to successfully deploy & use both the contracts & the ships log on any provider (public, private or local). Also an additional guide on how to use a specific ERC20 token from a contract address rather than the default Ether w/ the Wyvern contracts + ships-log js. Should include where & how ships-log js grabs information to display on html page as well. Should be straight forward and easy to implement on any network with any collectibles that meet Openseas metadata standard.

Payment Module Add-on1. we need to define a 3 new variables [payment_address, rebate_percent, fee_percent]. payment_address - this should be one address to be defined by owner - this should be done at the control panel level - from control panel you should be able to see and change the payment_address - by default it should be the owner address rebate_percent - this is a percentage that will be defined by owner - it should be manageable from the control panel - by default it should be 0 - this variable will be used to calculate the rebate fee_percent - this is a percentage that will be defined by owner - it should be manageable from the control panel - by default it should be 0 - this variable will be used to calculate the fee - right now it is hard coded at 1% 2. We need a script page that will do the following: a. Allow user to input payment amount [Page 1]: Enter Payment Amount: $136.00 - If correct press: Enter {this is a button to go to next page} b. New Page [Page 2]: Payment Amount: $136.00 {this is the payment amount from page 1} Payment Address: 0x3cA531ad690BcF8f21bE5a1D5Aa7921600490be3 {this will be the payment_address} QR Code image goes hear.... {this is the QR code from the payment_address} Logic: on excel file.
Owner Interface in expressJsI need a control interface for an ERC20 contract to show 6 columns called "name", "last name", "email address", (these columns can be left blank as text fields for now), white list (shows a button add or remove depending if they're on it currently + allows access to change there status by clicking the add or remove), and a fee-exclusion list that works the same way as the white-list column showing add or remove. Table should be sort-able by column header title. Last request would be to add changes to white-list or fee-exclusion list to a log that keeps track of users that executed the change and address added/removed, and list to which it was added .
All Address Returning Script - Refinement of ERC20 Smart Contract1. JS to return all addresses in white-list. (need to get into Excel preferably). 2. JS to return all addresses in node. (need to get into Excel preferably). 3. create exception list for addresses to avoid the 1% fee when using transfer function. 4. ability to set the address to where the 1% fee is sent to. Should be a variable that can be set.
Hey awesome sounds great, I'll do it. I'm using this contract inheriting from the new open zeppelin (2). So if it could be done on this one it would be fantastic. I'm using Remix IDE to compile not that it matters to much. https://github.com/OpenZeppelin/openzeppelin-solidity ------------------------------------------------------------------------------------------------------------------------------------ pragma solidity ^0.4.24; import "./ERC20Pausable.sol"; import "./ERC20Burnable.sol"; import "./ERC20Capped.sol"; contract Simpletoken is ERC20Pausable, ERC20Capped, ERC20Burnable { uint256 public constant INITIAL_SUPPLY = 100000000000000000000000000000 * (10); uint constant public decimals = 18; string constant public name = "Simple"; string constant public symbol = "SMP"; constructor (uint256 cap) public ERC20Capped(cap) { _mint(msg.sender, INITIAL_SUPPLY); } }
ERC20 (1%) Overall Transfer() Percentage Fee To Owner WalletWrite a smart contract that takes 1% of the overall ERC20 transaction and sends the coin to the owner wallet upon any usage of the default Transfer() function (to send ERC20's).
ERC20 Transfer Restricted To WhitelistWrite a smart contract that restricts the default transfer function (of an ERC20 using the Open Zeppelin standard) to only addresses on a white list (looks through a text file of addresses).
