This document describes a simple contract in pseudocode and gives a couple of test cases for it.
The challenge is designed to be fairly easy to implement in a language of choice, compiled to wasm and interacted with. It is loosely based on the ERC20 token standard, named "WRC20", where the W stands for WebAssembly.
The contract has two features:
| void function(global){ | |
| if ('DataView' in global && 'ArrayBuffer' in global) { | |
| return; | |
| } | |
| var hide = (function(){ | |
| // check if we're in ES5 | |
| if (typeof Object.getOwnPropertyNames === 'function' && !('prototype' in Object.getOwnPropertyNames)) { | |
| var hidden = { enumerable: false }; |
| Script::Script() { | |
| } | |
| Script::~Script() { | |
| } | |
| void Script::Initialize(char* src) { | |
| v8::Isolate* isolate = v8::Isolate::GetCurrent(); | |
