Single Nominator Integration for Copper

Overview

This document explains how to integrate Copper's UI with Single Nominator TON smart contract that allows staking TON coins in a secure way. We assume that some other party is running the validator node and has already deployed the single nominator smart contract. Such party is for example Kiln.

Single Nominator Roles

• Single-Nominator - The single-nominator contract we are sending opcodes to, example: Ef9P..W1sl
• Owner - The Copper custodian wallet that is sending the opcodes, example: UQA6..SXYf

1. Simple web UI in JavaScript/TypeScript

   • Functional UI only, doens't need to look good design-wise or use any UI framework
   • One screen web app
   • Connect Metamask (wherever)
   • Shows one screen with the proposal question - hardcoded in the HTML
   • On this screen multiple choice with button "vote"
   • When click "vote" - offline JSON signature on:

TON NFT Standard - Feedback

The feedback is based on our review of TIP issue 62 and its example implementation.

Thank you for your hard work on creating a unified NFT standard! The community is learning a lot from your efforts. We have a rare opportunity to design a standard that is truly focused on delivering the best product, and is not driven by gas limitations like on other networks (ERC721 for example). We also have the opportunity to apply many lessons learned from previous implementations in the crypto community.

High level feedback

1. We propose to move all business logic from the NFT child to the NFT-Collection parent

• I'm working on an Iron-Man game in WebVR (using A-Frame library) and I want to replace the default VR hand model of A-Frame with a custom model of Iron-Man's hands.

• This is the default model in A-Frame of the VR hands - Left | Right. Please download it and take a look.

  • Alternatively, I've already commissioned a similar Spider-Man hands model and this was the result - Left | Right.

  • I think the Spider-Man result was excellent so please take a look.

• The result should be similar GLB files (left and right) that have a similar proportions/physical size and similar animations (with slight differences explained below). Take a look at the animation names and format in the default model because the result should be a drop-

• I'm working on a Spider-Man game in WebVR (using A-Frame library) and the game has an infinite procedurally generated city. I need help with texturing the environment and the buildings.

• I want to have 2 separate visual styles, so all textures need to be done twice in both styles:

  1. The first style is realistic - here is an example.

  2. The second style is vector/simpler geometries but more colorful - here is an example.

• For efficiency of the game, small textures I think are enough, Like 256x256 pixels or 256x512 pixels or 512x256 pixels.

• I want the hands to have more poly detail than the default model, I found this model that I like - HandRef1. Let's base the result on it (the high poly version). You ca
