DIAMOND BLUEPRINTER

EVM Compatible Smart Contract Creator that uses Audited On-Chain EIP-2535 Smart Contract Facets as blueprints that developers can use to build EIP-2535 Smart Contracts.

EIP-2535: Diamonds, Multi-Facet Proxy

Summary

The EIP-2535 smart contracts are extensible without having to redeploy existing functionality. Parts of a diamond can be added / replaced / removed while leaving other parts alone. They can be immutable or mutable. The EIP-2535 Standard enables people to write smart contracts with virtually no size limit, standardizes contract interfaces and makes interoperability easier to achieve.

The Diamond Blueprinter dynamically creates EIP-2535 Smart Contracts using existing on-chain and audited EIP-2535 facets. Using our plug-and-play system, you can create custom contracts that meet your exact needs using battle tested on-chain assets.

Problem

The problem experienced by the greatest number of Web3 Developers in the development of Web3 products as cited in the G7 Industry Report was a lack of off-the-shelf smart contracts that are commonly used. The contracts should be easy to find, should be queryable by common use cases, should be secure and should be battle tested.

Solution

The creation of hundreds of On-chain EIP-2535 Diamond Facets that act as battle tested function libraries. These functions and their addresses are stored in an accessible format such as a database and made available to the Diamond Blueprinter.

The Diamond Blueprinter organizes these functions as commonly used contracts that meet common use cases yet still allows the developer to further customize the contract to meet their specific needs.

Facet

A Facet is simply an On-Chain Library of Functions.

Facets are Reusable and Composable. A deployed facet can be used by any number of diamonds.

Different combinations of facets can be used with different diamonds.

It is possible to create and deploy a set of facets that are reused by different diamonds over time.

The ability to use the same deployed facets for many diamonds reduces deployment costs.

A limitation is that two external functions with the same function signature can’t be added to a diamond at the same time because a diamond, or any contract, cannot have two external functions with the same function signature.

A facet defines external functions and can define or use internal functions, libraries, and state variables.

A facet can declare state variables in structs. Each struct is given a specific position in contract storage. This technique is called Diamond Storage.

Getting Started

The prototype will consist of the following functionality:

50 (on-chain) EIP-2535 Diamond Facets that contain commonly used, battle tested functions that would be useful for creating a prototype.
Testing Suite for facets. Incorporate the Bugout Facet Inspector and Slither.
Storage Mechanism for all functions that are used in the facets. Store should be a data store that is friendly to recommendation engines.
Storage Mechanism for additional metadata required for contract assembly. Correlate metadata with stored functions.
Pre-assembled smart contracts that can be used for common use cases. Make them searchable.
Basic platform with rest / graphql api endpoints using the G7 Microservice Platform Boilerplate
Api endpoints that are needed to generate the required payloads.
Super simple UI/UX that provides:
- Ability to search for exiting contracts based on use case query. (list query)
- Ability to select a contract from the search results. (profile query)
- Once selected, ability to display a single contact and it's analytics.
- From the single contract display, ability to query additional functions. (list query)
- From the single contract display, ability to select a function and add it to the contract. (profile query)
- Ability to create a blank contract and the ability to add functions to it using above functionality.
- Ability to test the contract locally using Bugout Facet Inspector. Add slither as additional testing option.
- Ability to launch the contract into a testnet and run the tests again.

What problem does this really solve?

A single address for unlimited contract functionality. Using a single address for contract functionality makes deployment, testing and integration with other smart contracts, software and user interfaces easier.
Your contract exceeds the 24KB maximum contract size. You may have related functionality that it makes sense to keep in a single contract, or at a single contract address. A diamond does not have a max contract size.
A diamond provides a way to organize contract code and data. You may want to build a contract system with a lot of functionality. A diamond provides a systematic way to isolate different functionality and connect them together and share data between them as needed in a gas-efficient way.
A diamond provides a way to upgrade functionality. Upgradeable diamonds can be upgraded to add/replace/remove functionality. Because diamonds have no max contract size, there is no limit to the amount of functionality that can be added to diamonds over time. Diamonds can be upgradeable or immutable. It is also possible to make an upgradeable diamond and then at a later time remove its upgrade capability.

Is this just another walled garden designed to monetize something that's freely available?

No. The entire platform is open sourced.
No. The list of available facets and the functions that are included in them is freely available.

Ok.. then how do you make money?

We have hosted the exact system that's freely available in this repo and added a super snazzy user interface to it. We charge a fee to use our interface.
We have received grants to help us audit our contracts.

How do I know the contracts are secure?

Look at the metadata for each contract in the database. We add audit details and contract analytics in the contract metadata.
