Union Protocol Implementations
There are several existing implementations of the Union protocol for different execution environments.
The CosmWasm implementation of the Union Protocol supports any chain that supports at least CosmWasm 2.0. This is also the implementation that runs on the Union chain.
The implementation can be found here: https://github.com/unionlabs/union/tree/main/cosmwasm/ibc-union
The EVM implementation of the Union Protocol supports any EVM implementation that supports at least the Byzantium fork.
The implementation can be found here: https://github.com/unionlabs/union/tree/main/evm
The Aptos Move implementation of the Union Protocol supports the Move version used by Aptos.
The implementation can be found here: https://github.com/unionlabs/union/tree/main/aptos
The Sui Move implementation of the Union Protocol supports the Move version used by Sui.
The implementation can be found here: https://github.com/unionlabs/union/tree/main/sui
The Cairo implementation of the Union Protocol supports Cairo, the smart contract language used on Starknet.
The implementation can be found here: https://github.com/unionlabs/union/tree/main/cairo
Note that this is still in active development.
