Project Summary

The project will support UCAN development focused on adoption, developer tooling and current projects using UCANs like Storacha.

Current implementations and tooling were made for previous UCAN spec < 1.0 version, this grant will update or create implementations and tooling for the new UCAN 1.0 spec version and beyond.

Impact

• Solutions like SIWE, Metamask Delegation kit and Smart Account/wallet focus only on blockchain use cases while UCAN can also support p2p and dweb user flows beyond blockchain.
• There is currently no up to date implementations and tooling that developer can use to integration UCANs in apps and services.
• Hard to adopt UCAN in languages with no implementation and no way to “curl” an UCAN API

Outcomes

• High fidelity, up to date (v1.0) website a la jwt.io with debugger builtin

• JavaScript v1.0 core implementation that can be used or integrated in viem/walletconnect

  • Support EIP-191(signature type) for Sign in with UCAN and SIWE integration

• Generic Chrome extension for UCAN request analysis and debugging based on the HTTP bearer spec https://github.com/ucan-wg/ucan-http-bearer-token

• Generic http server relay/json rpc generator

  • Enable UCAN API terminal “curl” use cases like CLIs or any other http standard clients
  • Bonus: From one base delegation with all the capabilities generates a json rpc schema with which clients and RPC relay server can be created

• Support wallet EIP-191 UCAN based signatures with Metamask Signature Insights for fully descriptive description about the data being signed.

  • Using filsnap or another UCAN specific snap

• Developer example dapps, 101s, hackathon kit

  • UCAN RPC apis, RPC endpoints with Authz/Authn builtin
  • Secure channels with UCANs (AWAKE)

• Support Storacha UCAN system in filsnap to hold delegations and delegate upload capabilities further to any other dapps on behalf of the user.

  • Bonus: support wallet delegation sync using Walletconnect APIs like

  https://specs.walletconnect.com/2.0/specs/clients/core/storage/

  https://specs.walletconnect.com/2.0/specs/clients/core/sync/

• Research generic support for UCAN in Wallets using WalletConnect enabling signing and delegation sync between wallet instances (multiple devices).

Adoption, Reach, and Growth Strategies

• Use the newly created Website to reach and engage with developers
• Enable new developers to build apps using the quickstarts and other resources created in the scope of this grant
