PrivaDEX

February 28, 2023 · View on GitHub

PrivaDEX is the cross-chain DEX aggregator native to Polkadot. As an example, you can swap from USDC (Wormhole) on Moonbeam to ARSW on Astar in one click.

Technical notes

All crates must be kept no_std compatible so that we can run them in an ink! contract environment. This means you need to mark src/lib.rs with

#![cfg_attr(not(feature = "std"), no_std)]
extern crate alloc;

Otherwise, the crate by default links in libstd and you run into errors like the below:

error: duplicate lang item in crate `ink_env` (which `pink_extension` depends on): `panic_impl`.
error: duplicate lang item in crate `ink_allocator` (which `ink_env` depends on): `oom`.

Build Docker image and start Docker container

# Build image
docker build -t privadex_chain_metadata .
# Create and start container
docker run -it --name privadex_chain_metadata privadex_chain_metadata

If you have already created the container, you can enter it by starting and attaching the container:

docker start privadex_chain_metadata && docker attach privadex_chain_metadata
