If a wallet already holds ETH, buying Telegram Stars takes three steps: username, amount, Optimism confirmation.
ETH and a card payment both land Stars in minutes — the difference is ETH needs a wallet, a card needs a bank that allows the charge.
Double-check the Optimism address before sending — ETH sent on the wrong network can't be recovered automatically.
Stars post automatically once the transaction gets its confirmation — no need to contact support.
Only send ETH on Optimism to the address shown; other networks aren't monitored for this payment.
