Open Grant Proposal: Dokrypt — Filecoin/FVM Development Toolkit

Name of Project: Dokrypt — Filecoin/FVM Development Toolkit

Proposal Category: Developer Tools & Libraries

Proposer: dokrypt-org

Do you agree to open source all work you do on behalf of this RFP?: Yes (Apache-2.0)

Project Description

Dokrypt is an open-source Web3 development toolkit (CLI) that simplifies dApp development with project scaffolding, local chain management, state snapshots, chain forking, and stress-test scenarios. Think of it as "Docker for Web3" — currently supporting EVM chains (Ethereum, Arbitrum, Polygon, Base, Optimism).

We propose adding first-class Filecoin/FVM support to Dokrypt, enabling developers to:

1. Scaffold FVM projects with a built-in fvm-basic template including FEVM smart contracts, storage deal helpers, and pre-configured local Filecoin node setup
2. Test storage deals locally with commands to create, verify, and retrieve mock storage deals against a local Lotus devnet
3. Fork Filecoin mainnet/calibration for testing against real state
4. Run FVM-specific stress-test scenarios (storage price spikes, deal expiry, sector faults)

This lowers the barrier to entry for Filecoin development significantly — new developers can go from zero to a working FVM project in under 60 seconds.

Value

What are the benefits to getting this right?

• Dramatically reduces onboarding friction for FVM developers
• Provides reproducible local testing for storage deals without needing real FIL
• Brings battle-tested DX patterns from EVM tooling (Hardhat/Foundry-style) to the Filecoin ecosystem
• Increases the number of developers building on FVM

What are the risks if we don't get it right?

• FVM developer experience remains fragmented
• Developers default to EVM-only chains due to easier tooling
• Storage deal testing continues to require testnet FIL and slow feedback loops

What are the risks that will make executing on this project difficult?

• Lotus devnet API compatibility may differ from mainnet
• FVM is still evolving; we'll need to track breaking changes
• Cross-platform support for Lotus node binaries

Deliverables

Milestone 1 — FVM Project Template & Local Node ($12,000, 3 weeks)

• Built-in fvm-basic project template with:
  • FEVM smart contracts (Solidity targeting FVM)
  • Storage helper contracts
  • Pre-configured dokrypt.yaml for Filecoin local node
  • README with FVM-specific guides
• dokrypt up support for starting a local Lotus devnet
• dokrypt init --template fvm-basic scaffolding
• Unit + integration tests
• Documentation on docs.dokrypt.com

Milestone 2 — Storage Deal Testing Commands ($12,000, 3 weeks)

• dokrypt storage create — Create mock storage deals on local devnet
• dokrypt storage verify — Verify deal status and retrieval
• dokrypt storage list — List active deals with status
• dokrypt storage import — Import data for storage deals
• Gas estimation for storage-related transactions
• Pre-funded test accounts with local FIL
• Unit + integration tests
• Documentation

Milestone 3 — FVM Scenarios & Polish ($6,000, 2 weeks)

• FVM stress-test scenarios:
  • storage-price-spike — Simulate storage cost increases
  • deal-expiry — Fast-forward time to expire deals
  • sector-fault — Simulate sector faults and penalties
• Chain forking support for Filecoin mainnet and calibration testnet
• End-to-end testing of full workflow
• Tutorial: "Build Your First FVM dApp with Dokrypt"
• npm + Docker release with FVM support
