Fix leaderboard: add missing contract environment variables

[Copilot]

Leaderboard was not displaying because NEXT_PUBLIC_CONTRACT_ADDRESS and NEXT_PUBLIC_CHAIN_ID were missing. The isContractConfigured() check in lib/contract.ts returned false, causing getLeaderboard() to short-circuit with an empty array.

Changes

• Removed env.local - incorrectly named file (Next.js requires .env.local with leading dot)
• Added .env.example - documents all required environment variables including:
  • NEXT_PUBLIC_CONTRACT_ADDRESS=0x781158C06D333b31a58D42DF5eBB5872B0734cD5 (TriviaPoints contract on Base Mainnet)
  • NEXT_PUBLIC_CHAIN_ID=8453 (Base Mainnet)
• Updated .gitignore - allow .env.example while ignoring other env files

Configuration

Users deploying this app should:

cp .env.example .env.local
# Update NEYNAR_API_KEY with actual key

Contract addresses are pre-configured for Base Mainnet. Optional NEXT_PUBLIC_RPC_URL can be set for dedicated RPC endpoints.

Screenshot

Leaderboard now attempts to fetch on-chain data from the TriviaPoints contract. Requires network access to mainnet.base.org in production.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fonts.googleapis.com
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/Triviacast/Triviacast/node_modules/next/dist/server/lib/start-server.js (dns block)
• mainnet.base.org
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/Triviacast/Triviacast/node_modules/next/dist/server/lib/start-server.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

Fixes the leaderboard not rendering by ensuring the required contract configuration environment variables are documented and can be set correctly in a Next.js-compatible way.

Changes:

• Removed incorrectly named env.local file (should be .env.local in Next.js).
• Added .env.example documenting required contract/chain configuration (and other related vars).
• Updated .gitignore to keep ignoring env files while allowing .env.example to be committed.

Reviewed changes

File	Description
env.local	Removes a mistakenly named env file that was being relied on locally.
.gitignore	Ensures .env.example can be committed while other .env* files remain ignored.
.env.example	Provides a template for required env vars (notably contract address + chain id) to unblock leaderboard fetching.

Comments suppressed due to low confidence (1)

env.local:1

• The removed file contained a real-looking NEYNAR_API_KEY value. Even though the file is deleted, the key remains exposed in git history; please rotate/revoke that key (and any other secrets that may have been in this file) and set a new value via .env.local/CI secrets.
