Cross-Shard Transaction

Cross-Shard Composability: atomic swaps of assets, inter-shard contracts

Harmony’s shards are similar to Cosmos’s zones and Polkadot’s parachains, but our shards offer simpler interface and more uniform security for developers. We are developing cross-shard transactions, comparable to Cosmos’s Inter-Blockchain Communication (IBC) and Polkadot’s Cross-Chain Message Passing (XMCP) but specialized for uniform shards.

Progress Update:

We are working with François-René Rideau from https://mukn.io for the implementation of cross-shard smart contract transactions. They are still in the design proposal phase and will soon update us with the proposal and an implementation timeline.
