Olesia Wallet.

Online send / receive — testnet. A companion to the offline generator.

Hot wallet — testnet only. Your seed is typed into this page and used to sign in your browser. It is never stored and never leaves this tab, but a web page is not cold storage. Do not enter a mainnet seed here. For real funds, generate and sign offline.

Network Your 24-word seed (paste one, or generate a fresh testnet wallet)

Receive address

Send testnet coin here, then Refresh. (Same BIP-84 derivation as the offline Olesia generator, so a seed made there works here.)

Balance

Send

Sweep (send everything, minus fee)
