Marigold is always seeking to contribute and improve the Tezos ecosystem, and, to that end, we are proud to announce the launch of Batcher, the batch clearing DEX, on Tezos mainnet.
Batcher is a new type of DEX that provides a dark pool-like trading environment without using liquidity pools or the issue of significant slippage. It has been designed to be composable with other high liquidity paths in the Tezos ecosystem, specifically the Sirius DEX; thus, the two launch pairs are tzBTC/USDT and tzBTC/EURL.
## Mainnet
Batcher is officially available on mainnet from today.

[Batcher Contract (Mainnet)](https://tzkt.io/KT1CoTu4CXcWoVk69Ukbgwx2iDK7ZA4FMSpJ)
## Ghostnet
Batcher has been available on Ghostnet for sometime. If you want to test your trade out, tokens for use in trading can be sourced from Marigold’s [faucet](https://faucet.marigold.dev).

## Oracle
The prices used in Batcher are provided by a forked version of Harbinger that is run and maintained by Marigold.dev. Whilst the on-chain contracts are unchanged, the signer and poster parts have been adapted to fit securely into the Marigold.dev infrastructure.

## Audit
The Batcher on-chain contract has been audited by ‘Inference AG’. The audit found no major issues, and the publication of the full report is imminent. We will add an addendum to this blog post with the link to the report as soon as it becomes available.
## Blog Posts
In the development roadmap for Batcher, Marigold.dev has published a number of blog posts detailing how Batcher works and changes made on the path to mainnet. These blog posts are one of the best resources for learning about Batcher.
## FAQs and Videos
In addition to the blog posts, a number of FAQs and videos showing the operation of Batcher are available on the Marigold.dev [project page](https://www.marigold.dev/batcher).

The Batcher contract and UI are together in the same repo. The Harbinger fork is in a separate repo.
