ckb-auth

A consolidated library featuring numerous blockchains authentication techniques on CKB-VM. More details in auth.md. We also write two simple script to demonstrate how to use this library:

• c demo
• rust demo

Motivation

The CKB-VM in CKB has provided a multitude of advanced smart contract functionalities that are not typically found within other blockchain networks. CKB presents a seamless solution for implementing blockchain interoperability. Through the utilization of ckb-auth, a sophisticated smart contract library, users can effortlessly access CKB assets from alternate blockchain wallets, such as Ethereum or Bitcoin, without the use of a CKB wallet.

To illustrate, considering a scenario where Alice only possesses an Ethereum wallet, Bob can transmit assets, including CKB or NFT, to Alice. With the application of ckb-auth, Alice can effectively utilize and transfer these assets using her Ethereum wallet without requiring the creation of a CKB wallet throughout the process.

Integration

The following blockchains are supported:

• Bitcoin
• Ethereum
• EOS
• Tron
• Dogecoin
• CKB
• Litecoin
• Cardano
• Monero
• Solana
• Ripple

Build

git submodule update --init
make all-via-docker

For more details, please check out CI script.

Test

All test case commands are located in tests/Makefile.

Installing Dependencies

make install_all

Running All Tests

cd tests && make all_tests

Test with Spawn (activated after hardfork 2023)

Before running test cases with spawn support, please install ckb-debugger for next hardfork:

cargo install --git https://github.com/nervosnetwork/ckb-standalone-debugger ckb-debugger

Then run:

cd tests/auth_spawn_rust && make all
