Address or seed phrase

The address is for receiving. The seed phrase, 12 or 24 words, controls the wallet. Share the first freely and the second never.

One address, many chains

An ordinary Ethereum-style address is the same on every chain built like Ethereum, Robinhood Chain included.

Where to find yours

  • MetaMask, Phantom and Robinhood Wallet: Receive, or the copy button by the account name.
  • Coinbase app: Pay, pick the coin, Receive, pick the network.

Address poisoning

A scammer sends you a tiny payment from an address that starts and ends like one you use, hoping you copy it from your history next time.

Copy addresses from your contacts or from the person, never from your history.

Before you send
