Stateless and Cross-Chain Web3 App Design

This architecture demonstrates patterns and best-practices for building stateless, client-side applications that derive all state from onchain events without requiring traditional databases or user account systems.

Since we're directly consuming onchain data we have automatic synchronization with the current chain state. By leveraging subgraph data along with client-side processing, we can:

Infer relationships from on-chain activity (e.g., multiple accounts managed by a single wallet)
Derive the full onchain state from raw events (e.g., transaction status, account balances)
Scale horizontally without additional backend infra
Maintain a single onchain source of truth

`npm bump + publish` helper

an interactive shell script for bumping npm package versions.

features

prompts for version bump (major/minor/patch)
detects and optionally runs lint, test, build, prepublish, and prepare scripts
checks for unstaged git changes and warns the user
supports --dry-run mode

You are an expert in Solidity and smart contract security.

General Rules

Cut the fluff. Code or detailed explanations only.
Keep it casual and brief.
Accuracy and depth matter.
Answer first, explain later if needed.
Logic trumps authority. Don't care about sources.
Embrace new tech and unconventional ideas.

Xeon Protocol Bug Bounties

The v1-core repository is subject to the Xeon Protocol Bug Bounty (the "Program") to incentivize responsible disclosure of vulnerabilities. We are offering XEON token rewards for submissions that meet eligibility criteria.

Scope

The scope of the Program is limited to bugs that result in the direct loss of user or protocol funds when interacting with Xeon v1 contracts, and bugs that interfere with the ability of peripheral contracts to properly interact with core contracts.

VST Day-Trading Strategy

Jon Bray

Strategy Created: 12-Sep, 2020 Current Revision: 25-Jan, 2023

This strategy is most accurate for day trading using chart intervals less than 30 min. Most notably 1m, 2m, 15m although by more carefully monitoring stop-loss (SL) and take-profit (TP), it can be applied to position trading using 1H and 4H chart intervals as well. This strategy is most effective when the current volume is at or above the daily average.

This strategy works well for the following asset classes: Crypto, Stocks, Commodities, Indexes
