Frequently Asked Questions

What is Zeko?

Zeko is an Ethereum rollup for zkApps. Applications use TypeScript and o1js, while recursive Zeko proofs are verified through SP1 and settled by Ethereum contracts.

Is Zeko still a Mina rollup?

The project's current direction is Ethereum settlement. The execution layer retains Mina-derived ledger, zkApp, address, and proof formats. Older Mina-backed deployments and their documentation remain separate legacy environments.

Can I deploy Solidity contracts on Zeko?

Zeko applications use the zkApp model, not EVM bytecode. Solidity contracts implement settlement and custody on Ethereum. See Developer Getting Started.

Which wallet do I need?

The Ethereum bridge uses an Ethereum 0x... account and a Zeko B62... account. MetaMask handles Ethereum operations and the Zeko Snap provides L2 signing where supported. Local Snap development uses MetaMask Flask; the bridge also supports Auro as a compatible Zeko signer. Use the option enabled by your deployment.

Why is my Zeko address different from my Ethereum address?

Zeko retains its existing public-key and account format. The Snap's B62... address belongs to L2; MetaMask's 0x... address belongs to Ethereum. Use the destination address required by the bridge or transfer form.

Do I need MINA?

The Ethereum-backed Zeko deployment uses ETH. MINA and tMINA in legacy network documentation refer to separate Mina-backed deployments. Old faucets do not fund ETH on the Ethereum rollup.

Which assets can I bridge?

Native ETH and registered ERC-20 assets supported by the deployment. An arbitrary L2 custom token is not automatically bridgeable. Follow the asset selector and registry mapping in the Ethereum bridge.

Why is a deposit or withdrawal still pending?

Deposits require Ethereum finality, bridge processing, synchronization, and L2 finalization. Withdrawals require L2 inclusion, Ethereum settlement, the withdrawal delay, and a claim transaction. The explorer shows these stages separately.

Are confirmations instant?

L2 inclusion can precede settlement. It is not Ethereum finality, and it does not immediately make a withdrawal claimable.

Are all transactions private?

No. zkApps can prove statements about private inputs, but public account updates, balances, fees, and bridge activity remain observable. Privacy depends on application design.

Is the Ethereum integration production-ready?

It is experimental and targets Sepolia. The current deployment model is permissioned and uses committee DA. Full Ethereum blob-to-batch-root binding remains future work. Read the security model and the deployment's current release status.
