Miden Partner Mainnet Launch
Miden · Releases & Updates · October 26, 2026
Miden opens its Partner Mainnet on October 26, 2026: a privacy-focused ZK chain with client-side proving, private state and Rust smart contracts, launching first with partner teams.
Miden is a privacy-focused ZK blockchain spun out of Polygon Labs and connected to Agglayer. It enables private, client-side proving: users prove their own transactions locally without exposing state to the network. Miden uses the STARK-based Miden VM with full Rust compiler support. After 16 testnet versions since May 2025, Miden opens its Partner Mainnet on October 26, 2026, an early-access mainnet that launches first with partner teams, with invite codes distributed via the Bread wallet.
- Private by default: user state is self-custodied and proven locally, not exposed onchain - Rust-native smart contracts: write any in-protocol logic directly in Rust - Client-side proving: each user proves their own transactions, reducing validator load
