Miden

Miden is a privacy-focused ZK blockchain: transactions are executed and proven on the user's device, and only the proof reaches the network. The project was incubated at Polygon and spun out as an independent company in April 2025, with a $25M seed led by a16z crypto, 1kx and Hack VC.

On October 26, 2026 the partner mainnet goes live, invite-only through Bread, Miden's new private, self-custodial wallet for iOS, Android and Chrome. Access codes are sent by email, in waves. No token or airdrop has been announced: using Bread early is a bet on a possible reward for early users.

How to participate

1. Join the early access list on Bread with your name and email (Telegram optional). You get a place in line: keep it.
2. Wait for your code by email: codes go out in waves from October 26. Joining does not guarantee a spot, so stay on the list for the next waves.
3. Install Bread (iOS, Android or Chrome extension) and enter your code during onboarding. If you already used Bread on testnet, you need an in-app reset and a fresh wallet: test funds don't carry over.
4. Choose your account type: with Guardian you can recover the account if you lose your device; the more private mode has no recovery. Store your recovery phrase offline.
5. Use Bread with a few dollars: make a first deposit from Ethereum, receive and send a payment, swap on Miden, verify account recovery and try an arcade mini-game inside the app. Network fees are paid in USDCx and the wallet comes pre-funded for about 50 transactions.

Risks: Bread is in beta and the partner mainnet is temporary: you'll have to withdraw your funds before it ends, following the official instructions. The balance cap is about $1,232. Bread is unavailable in some countries and Earn is excluded in the UK and New York State. The airdrop is not confirmed.

Anti-scam: only use miden.xyz and the store links on the site. Miden never asks for your recovery phrase: anyone who does, even posing as support, is a scammer. The old Miden Wallet has been replaced by Bread. DYOR.
