Hi everyone, we have a new Sign-in solution for Bitcoin Wallet, so called “Sign-In with Bitcoin” aka `ic-siwb`. The project is forked and modified from the project we love: [`is-siwe`](https://forum.dfinity.org/t/announcing-ic-siwe-use-ethereum-wallets-to-login-to-ic/27450), thanks @kristofer . If you are familiar with `ic-siwe`, then you will find it very easy to configure and use the `ic-siwb`. ## Features - **Bitcoin Wallet Sign-In** : Sign in with popular btc wallets (currently with Wizz Wallet and Unisat wallet ) to generate an IC identity and session. ----- forked from SIWE ---- - **Session Identity Uniqueness** : Ensures that session identities are specific to each application’s context, preventing cross-app identity misuse. - **Consistent Principal Generation** : Guarantees that logging in with an Bitcoin wallet consistently produces the same Principal, irrespective of the client used. - **Direct Bitcoin Address to Principal Mapping** : Creates a one-to-one correlation between Bitcoin addresses and Principals within the scope of the current application. - **Timebound Sessions** : Allows developers to set expiration times for sessions, enhancing security and control. - **Prebuilt Identity Provider** : Provides a prebuilt canister that can be integrated into any Internet Computer application, independent of the application’s programming language. ## TODOS: - **Integrated Tests** : we need test cases to make sure the code is running correctly. - \*\*More wallet supports \*\*: we need more wallet supports, for example: OKX Wallet, Xverse, Hiro and more. And customizable provider to support more. - **Prebuild and Deployed Canister** : we need a canister to generate global stable identity, it’s best to be governed, upgraded and run by NNS. - **Documentation** : we need documentation on everything, codes and examples. - **Publishing** : crates and npm packages. ## Next steps: 1. more developers use and fork, and maintain the code. 2. more adoption by projects 3. your ideas, 😃. @domwoe @kristofer @bob11 > **[GitHub - AstroxNetwork/ic-siwb: SIWB, Sign in with Bitcoin for ICP, the Internet...](https://github.com/AstroxNetwork/ic-siwb)** > > SIWB, Sign in with Bitcoin for ICP, the Internet Computer.

Updates: To add support for Xverse and more bitcoin compatible wallets. We also need to support BIP-322-simple Signature Verification, see [BIP-0322](https://github.com/bitcoin/bips/blob/master/bip-0322.mediawiki). Since there is no existing BIP322 rust crates we can use directly. We have to build it our own and also need to support both Segwit v0 and v1. After we implement this, the final API call will add another parameter to the login parameter. ```rust pub enum SignMessageType{ ECDSA, Bip322Simple } ``` the siwb\_login function signature will be ```rust #[update] fn siwb_login( signature: String, address: String, public_key: String, session_key: ByteBuf, sign_message_type: SignMessageType, ) -> Result ``` ---

BIP322 is supported. Currently Xverse is supported. For the list, I think I will add more by the weekend ---

Hi @neeboo , Amazing work on `siwb`! 🔥 I’m trying to use it in my project but struggling to figure out the parameters for deploying `ic_siwb_provider`. Could you update the README and Makefiles with the commands and steps for the whole setup? Thanks so much for your help! ---

@neeboo , Failing to build the package. ```auto error[E0282]: type annotations needed for `Box<_>` --> /Users/foo/.cargo/registry/src/index.crates.io-6f17d22bba15001f/time-0.3.31/src/format_description/parse/mod.rs:83:9 | 83 | let items = format_items | ^^^^^ ... 86 | Ok(items.into()) | ---- type must be known at this point | help: consider giving `items` an explicit type, where the placeholders `_` are specified | 83 | let items: Box<_> = format_items | ++++++++ For more information about this error, try `rustc --explain E0282`. error: could not compile `time` (lib) due to 1 previous error warning: build failed, waiting for other jobs to finish...

@neeboo I’m still failing to deploy the `ic-siwb` locally! here is the error that I’m receiving with the release wasm: ```auto Error: Failed while trying to deploy canisters.

I was able to fix the problem by replacing the candid file. candid file provided in `release/ic_siwb_provider.did` doesn’t matches to `package/ic_siwb_provider/ic_siwb_provider.did` ---
