General FAQs

This document addresses some common inquiries regarding Prom. For more in-depth information, please refer to our comprehensive documentation.

What Exactly is Prom network?

Prom is a high-performance scalable network based on Polygon CDK. Prom submits its proof of transaction to the additional chains on top of the chosen Settlement chain, building the bridge between ecosystems.

Key Features of Prom?

• Multichain support: Prom can submit its proof of transaction across multiple networks, including both EVM and non-EVM compatible chains, which ensures a high level of decentralization and 100% uptime;

• Efficiency & Scalability: reduced costs and enhanced scalability with zkSNARKs;

• High-Speed Transactions: Polygon Zero's tech brings exceptional speed to every transaction;

• Robust Security: Inheriting Ethereum's security, Prom ensures the highest level of data integrity;

• EVM Compatibility: Seamless integration in a familiar EVM environment;

Gas Fee Reduction Expectations with Prom?

Users can look forward to a significant reduction in gas fees relative to Ethereum Layer 1. Prom's protocols batch multiple transactions, spreading the cost of a single Layer 1 transaction over numerous transactions.

Does Prom Utilize a Separate Token for Transactions?

Yes, transactions in Prom will utilize the PROM token for gas fees. Prom also accommodates Account Abstraction via ERC-4337, enabling transparent fee payment with any token from the user’s perspective.

Suitable dApps for Deployment on Prom?

Any dApp that's EVM-compatible can be deployed on Prom, with the exception of those requiring specific precompiled contracts not currently supported. Detailed information on compatible precompiled contracts is available in our documentation.

Prom Capability for Cross-Chain Interactions?

At present, Prom does not support cross-chain functionalities. However, our future roadmap includes enabling asset movement across various networks, though not available at launch.

Principal Use Cases for Prom?

• DeFi Applications: High security and efficient capital utilization make it suitable for DeFi.

• NFT, GameFi, and Enterprise Applications: Beneficial for these sectors due to low gas fees, fast transaction speeds, and robust security.

• Payments: Ideal for users seeking real-time transactions with minimal fees.

How Reliable are Prom Proofs on Layer 1?

The accuracy of these proofs is assured by our zkRollup smart contract. Their reliability stems from data availability and the ease of verifying the SNARK proofs.

Compatibility of Prom with Solidity and Vyper?

Yes, Prom supports all languages that compile to EVM opcode, including Solidity and Vyper.

What Constitutes an RPC Node in Prom?

An RPC (Remote Procedure Call) node in Prom is a JSON-RPC interface compatible with Ethereum, enabling seamless integration with existing tools like Metamask, Etherscan, and Infura. Its operation is akin to Ethereum nodes such as geth.

Prom Support for JSON-RPC EVM Query Specifications?

Prom supports all standard queries (eth_* endpoints). Efforts are underway to extend support to additional endpoints like debug_*.
