Sign in with your CoCo account. Eligibility comes from the voter wallet linked to that account; the ballot is signed in this browser.
Using the CoCo Vote app? Open Settings → Backup Wallet in the app to view the voter wallet's 12 words,
then enter them below. The words stay in this browser tab and are never sent to the server.
These words must derive the eligible voter wallet shown above. They are used only in this browser tab; the mnemonic is not stored or sent.
How it works: the server checks the voter wallet linked to your signed-in account against the election snapshot.
Your browser signs the exact castVoteWithProof payload with the ed25519 key; the server relays the signed extrinsic and never sees your seed. One ballot per eligible account.
