Weekly Dev Update #6

THORChain Weekly Dev Update for Week 27 Aug— 02 Sep 2019

Overview

The team have internally shipped testnet on time, and are getting it ready for public access, including front-end integration.

BEPSwap Development

The team are working on 5 parallel streams of effort to deliver BEPSwap, which remains the primary focus.

Cosmos-powered SDK StateChain

Cross-chain infrastructure

Threshold Signature Scheme implementation

Front-end Integration for BEPSwap

Other development activities

The theme of the week was to begin API implementation, start frontend API integration, begin integration of the TSS signer in the environment.

StateChain

The Statechain is mostly complete and dependent now on integration with the Observer, Chain Service and Signer.

Cross-chain Infra

Updates to the Observer and begin building the Chain Service. Block explorer shipped to frontend.

• Update Observer to use the new statechain types
• Change binance block scanner to get tx detail from the node , instead of using binance api
• add tokens endpoint
• Prevent SQL injection
• add tradeData endpoint
• get tx data from binance node instead using binance API
• Continuously scan statechain for new events, and persistent it to influxdb

Threshold Signatures

This week began work to implement the TSS Signer with the Statechain infrastructure and required setting up a new testnet environment.

Front-end Integration

Work was done on generating programmatic coin icons, as well as a new Signer Modal and updated staking actions.

Programmatic Icons are generated by finding web-hex colours based on the first two letters of the symbol.

function generateIcon(string){
char[] ch = string.toCharArray();
int tempFirst = (int)c[0];
int tempFirst_integer = 64; //for upper case
if(tempFirst<=90 & tempFirst>=65){
int firstCol = (tempFirst-tempFirst_integer) ;
col1 = rainbowStop(firstcol);
}

int temp2nd = (int)c[1];
int temp2nd_integer = 64; //for upper case
if(temp2nd<=90 & temp2nd>=65){
int 2ndCol = (temp2nd-temp2nd_integer) ;
col2 = rainbowStop(2ndcol);
}}function rainbowStop(h)
{
let f= (n,k=(n+h*12)%12) => .5-.5*Math.max(Math.min(k-3,9-k,1),-1);
let rgb2hex = (r,g,b) => "#"+[r,g,b].map(x=>Math.round(x*255).toString(16).padStart(2,0)).join('');
return ( rgb2hex(f(0), f(8), f(4)) );
}

Modal Timer is a beautiful modal screen that conveys the progress of the transaction as it is taking place. There is also a matching header icon that mimics the timer.

The stake, trade and withdraw actions were also updated to make use of the beautiful “drag to stake” action slider:

Other Development

Work is ongoing with the BEP2Bot for BEP2 projects:

• News
• Wallet monitoring
