Reviewed and approved, vol. 2: Apillon’s progress did not go unnoticed
Successfully finalized Milestone 2 of the Substrate Builders Program; Milestone 3 tasks already in progress.

In May, Apillon officially became a member of the Substrate Builders Program. Since then, we’ve been working even harder to justify the faith and trust put into our venture by Parity Technologies.
By delivering what was planned — and some extra features as well — Apillon has completed Milestone 2 of the Substrate Builders Program.

Heart at work
Besides working on agreed-upon tasks to complete Milestone 2 successfully, a better part of the team’s resources was also directed into the Apillon Bounty Proposal (through Polkadot Treasury funds) that would make the Apillon platform an open-source common good infrastructure on Polkadot.
By bringing this plan to fruition, the platform would provide permanent freemium access to the Polkadot community, fostering Web3 adoption and general growth and enhancing the utility of Polkadot’s native DOT token.
Nevertheless, our progress under the auspices of the Substrate Builders Program was not hindered, as our development team even managed to fulfill some of the tasks designated to Milestone 3, as it went hand in hand with our current development plan.
“Apillon team delivers strongly on their vision, making good progress to become the go-to platform for future Web3 developers.”

Milestone 2 in the rear-view mirror
Apillon advanced on the ladder of Substrate Builders Program’s challenges but before we dive into the specifics, you can read through Milestone 1 tasks, all successfully completed.

As the list of current tasks performed is extensive, we have divided it into several sections:
I. The Apillon platform development
II. Apillon’s community building, initiatives, events
III. Apillon’s Treasury proposal
I. The Apillon platform development
First and foremost, parachain integrations are the most crucial part of the Apillon platform. Combined together or separately standing, they provide a range of fully-fledged services we want to offer to Web3 developers.
- Phala Network
The first integration of Phala Network resulted in a working demo of so-called Schrödinger’s NFT. The product leverages the ERC-721 Smart contract, deployed on Moonbeam Network, a Phat contract, custom-written by the Apillon dev team within Phala Network’s Closed Beta Program and the IPFS pinning service through Crust Network. The goal is to achieve private NFT data, accessible only via dedicated NFTs as a key.
This feature allows users to upload specific files and encrypt them using Phala TEE with an NFT in their wallet. Once encrypted, the file is saved on IPFS. Upon request, the file is then pulled from IPFS and decrypted using the same NFT that was used to encrypt it. For this solution, a custom Phat Contract was written in ink! programming language.
- KILT Protocol and Phase 1 of DID Vault
The service by KILT Protocol was integrated into the dashboard and can be used to log in to the app. Currently, the service is not yet live in production but it’s fully operational in the development environment.
As we have been developing the full Web3 Authentication service that enables users to pass the email attestation and receive their DID credentials from the platform, the question of a general DID storage immediately surfaced. The only supported tool that is currently able to hold the DID credentials is Sporran Wallet, which could represent a huge friction in the adoption if offered as the only solution we can provide to developers on Apillon.
That’s why, months ago, we started designing and developing a separate solution called DID Vault that would simplify the storage of the DIDs, eliminating the Sporran Wallet from the equation and offering users faster and simpler authentication processes without having them handle another wallet on their Web3 development journey.
- Penetration testing
To evaluate the platform’s security and check for vulnerabilities that could be exploited in case of attacks, penetration tests were done on the Apillon platform. Presented by the report of suggested improvements, the development team has already revised, implemented and released the upgrades to all environments and we’ve received the final confirmation and the overall rating.

- Freemium model in production
Apillon is currently running a Freemium business model, allowing users to use up to 5 GB of Web3 Storage service, take up to 5 GB of Web3 Hosting service and deploy 2 NFT collections through the NFT Service, all completely free of charge. In parallel, we have been developing an additional business model, allowing us to check the overall limits as well as assign extra limits to users that have specific needs. With that in place, we are ready to proceed with designing the paid models in the next few months.
- SDK development initiation
By continuously working on SDK and CLI, Apillon will soon be able to provide additional tools to speed up the development process on the Apillon platform. Both SDK and CLI tools already support Apillon’s Web3 Hosting service, while other services will soon be equipped too. Currently, the NFT Service and its SDK and CLI tools are being internally reviewed and will soon be up and running.
- Astar EVM smart contracts
By joining forces with Astar Network, the Apillon platform now offers multiple chains for deploying digital assets. Following the integration of Moonbeam’s ERC-721 smart contract connectivity on the platform in early May, Astar’s EVM connectivity is the next step toward unlocking true interoperability across multiple chains, all through the Apillon platform.

- NFT-displaying website templates
When NFTs are deployed through the Apillon platform, users should be able to display them on a website. When the Apillon NFT Service was released, the initial NFT template for the website was on JavaScript. Now, to streamline the process even further by offering more ways to arrive at the finish line fast and easily, there are React and Vue NFT templates ready to be used.

II. Apillon’s initiatives, events and community building
Web3 adoption cannot happen without joint efforts and collaborations among the teams within the Polkadot ecosystem. It’s crucial we spend time promoting the benefits of blockchain technology — by strengthening the existing Web3 community of believers and also by expanding our discourse outside of the Web3 realm.
- Web3Approved initiative
Web3Approved represents a joint initiative by Apillon and Crust Network aimed to promote the decentralization of operations within the Web3 ecosystem. To jumpstart the movement, the initiative offers IPFS hosting services for projects to host their websites — completely free of charge. The first 100 projects that join will be provided with free decentralized hosting for their websites for the next 100 years.

III. Apillon Bounty Proposal: Fostering Web3 adoption as a common good infrastructure solution on Polkadot
As of July 18, 2023, the Apillon Proposal is live on Polkassembly, ready to be voted upon.
Since June 19, 2023, we initiated the discussion by posting the Apillon proposal on both Polkassembly and Polkadot Forum. The aim of the proposal is to transform our Web3 development platform into an open-source common-good solution to provide Forever freemium access to developers building on Polkadot.
In accordance with the ecosystem’s meaningful feedback, we then decided to change some structural schemes and empower the community to have more say in the tranches being paid for Apillon’s work instead of asking for an upfront payment.
If Web3 is all about the community and democracy, it’s important how we go about making the ecosystem better. Here’s how we engaged and listened to the Polkadot ecosystem’s loudest preachers.

And here you can check through the changes we’ve made to the Proposal.

- Polkadot Forum post:
We have presented the proposal to numerous audiences, including Parity (Ecosystem 101 call), Substrate Builders Program (SBP Office Hours presentation), the Polkadot Community Call, and through multiple AMAs with different ecosystem teams on Twitter. We are thrilled with all the support we have received so far.
