About On-Chains Online
On-Chains Online is open-source, self-hosted token operations tooling built by Heifereum for teams shipping stablecoins and utility tokens across major public blockchains.
What this product is
On-Chains Online is a Web3-native dashboard for issuing and operating tokens. It speaks ERC-20 / ERC-1400 on Ethereum, BNB Smart Chain, Polygon, Avalanche, Base, Optimism and Arbitrum, and SPL on Solana. Operators can mint, burn, freeze, audit and monitor supply across every chain from one interface.
The dashboard is read-mostly. Every state-changing action is signed by the operator's own wallet (MetaMask or Phantom) in their own browser. We never custody funds, never see private keys, and never broadcast a transaction without an explicit local signature.
What this product is not
- It is not a custodial wallet, exchange, or money service business. We do not move funds on a user's behalf.
- It is not an investment platform. We do not list assets, accept deposits, or offer yield.
- It is not an airdrop site. We will never ask you to connect a wallet to claim, verify, or unlock anything.
- It is not affiliated with MetaMask, Phantom, Chainlink, or any blockchain foundation. Trademark references identify interoperability only.
Who builds it
On-Chains Online is built and maintained by Heifereum, an independent team focused on production tooling for stablecoin issuers and on-chain treasury operators. The dashboard source is available on GitHub.

Why we publish this page
New crypto domains routinely get flagged as suspicious by generic phishing classifiers. This page exists to make the ownership, scope and limits of On-Chains Online explicit so users (and crawlers) can verify what the project actually is before connecting a wallet.
