​
Security and Secrets

SignalArc must keep secrets out of source control and out of public documentation. This repository currently documents local/testnet prototype behavior only and does not claim production custody, production settlement, audit completion, or compliance approval.

​
Never Commit

  • .env
  • .env.local
  • Private keys
  • Seed phrases
  • Circle API keys
  • Blockscout API keys
  • WalletConnect project IDs when project policy keeps them local or deployment-only
  • Production database credentials
  • RPC secrets
  • Local database files
  • node_modules
  • .next
  • out
  • dist

​
NEXT_PUBLIC Variables

NEXT_PUBLIC_* variables are exposed to browser JavaScript. Safe examples:
  • Public API base URL.
  • WalletConnect project ID when intended for browser use and configured through deployment settings.
Never put secrets in NEXT_PUBLIC_*, including private keys, Circle API keys, database URLs, RPC secrets, or server-only credentials.

​
Backend Secrets

Local development database values may appear in Docker Compose for the local database. Production secrets must be configured outside source control through the deployment platform or a secret manager. Backend production secrets must not be written to Markdown files, committed examples, logs, frontend code, or generated artifacts.

​
Wallet Model

  • External wallets sign user transactions in the browser.
  • Backend must not sign user transactions.
  • No private key belongs in frontend or backend source code.
  • Circle embedded wallet is not implemented.
  • Circle SDK/API integration is not implemented in the current repository.

​
Smart Contract Status

  • Current contract is an Arc Testnet prototype.
  • It is unaudited.
  • It is not production custody.
  • It is not production settlement.
  • It does not prove mainnet readiness.

​
Circle

  • Circle API keys must never be placed in frontend code.
  • Circle API keys must never be placed in public docs.
  • Circle SDK/API integration is not implemented unless explicitly added in a future change.
  • Circle behavior that is not implemented or not documented by official Circle sources is unknown / not documented.

​
Deployment

  • DNS/live deployment is not approved or completed yet.
  • Production environment variables must be configured outside source control.
  • CORS must be reviewed before production deployment.
  • Production database credentials must use deployment secret management.
