WalletCore is also available in Rust

[Milerius]

Hey Gem team, great job with your project and thanks for using wallet-core! I'd like to point out that most of the important coins you use are also available in Rust from WalletCore with V2 features, such as Bitcoin, FFI generation, and more (such as protobuf access from Rust as well)

https://github.com/trustwallet/wallet-core/tree/master/rust

Note that for crate like SUI: https://github.com/trustwallet/wallet-core/tree/master/rust/chains/tw_sui we do not depends on big dependencies like Mysten Labs SUI which make us more optimized for low size binary (mobile platforms) and less security dependencies risk.

Note that also all crypto generation (not yet HDWallet, but at some point will be available as well) is available in Rust

All the interfaces also have FFI generations: https://github.com/trustwallet/wallet-core/tree/master/rust/wallet_core_rs

@Milerius thank you for the reaching out.

Do you plan to support split and stake functionality? https://github.com/gemwalletcom/core/blob/main/gemstone/src/sui/mod.rs#L27 to avoid having two separate transactions to perform a stake? Happy to use WalletCore for Sui, once this feature becomes available.

@Milerius could you guys please add custom cosmos network support? we'd like to fully use Wallet Core if it can support sign arbitrary cosmos sdk tx. One user case is to support skipprotocol

@Milerius Another feature request: Add script to publish Wallet Core Android to Maven Central or Local, F-droid needs all the components being compiled on their build server to get listed.

Hi @gemcoder21 , no we don't support split and stake operations per one transaction. We'll consider adding support for it in the future, thank you for the good point.

You can use SignDirect Protobuf message to sign an arbitrary transaction
https://github.com/trustwallet/wallet-core/blob/7523c9805ce094639dfbda6d643e439f5ef1705e/src/proto/Cosmos.proto#L240-L246

Please note you can specify any chain_info as well as tx_hasher and signer_info for custom chain support:

Consider using tools/android-release script.
To publish to the local Maven registry, you should replace publish command with publishToMavenLocal here:
https://github.com/trustwallet/wallet-core/blob/a60033f797e33628e557af7c66be539c8d78bc61/tools/android-release#L19

@satoshiotomakan Thanks for the replies, Wallet Core validates hrp inside, if a new chain hrp is not registered in the registry, it will throw an error saying invalid address or something, we did try to use Wallet Core to support https://www.saga.xyz/ but failed

[0xh3rman]

@satoshiotomakan sure, we do can publishToMavenLocal, but it would be nice to host it on maven central, hate to use github token to download a package

[satoshiotomakan]

Hi @0xh3rman, which version of WalletCore did you try? We added support for custom Cosmos chains at the 4.0.21 release: trustwallet/wallet-core#3669
I have one more example: https://github.com/trustwallet/wallet-core/blob/bbb99135847aa71898f085a6c681e3fbb162e530/rust/tw_tests/tests/chains/cosmos/cosmos_sign.rs#L65-L128

@satoshiotomakan Thanks for the reference, I probably used old version version
