Please note that zkApp programmability is not yet available on Mina Mainnet, but zkApps can now be deployed to Berkeley Testnet.

zkApps Roadmap

High-level overview of features available now, next, or later

Now

Mina zkApp CLI

• Scaffold projects & files
• Example projects
• Deployment
• Create a project with an accompanying UI — SvelteKit, NextJS, or NuxtJS

note

To view all commands offered by the zkApp CLI, install it via npm install -g zkapp-cli and then run zk --help.

• Built-in data types — Field, Bool, UInt32, UInt64, PublicKey, PrivateKey, Signature, Group, Scalar, & CircuitString
• Custom data types — a.k.a. Struct
• Composability
• Recursion — a.k.a. ZkProgram
• Events — writing events to the archive node
• Encryption & decryption — using Mina’s curves
• Actions & reducer
• Merkle tree
• Custom tokens
• Using on-chain values — a.k.a. protocol & account preconditions
• Local blockchain
• And more...

Data Availability

• On-chain state — 8 x 32 bytes of arbitrary data per zkApp account
• Off-chain storage — for Merkle tree data; see Tutorial 6

Other
