What is Nyx Alpha?

Nyx Alpha is an initial version of our app on Aztec Alpha Mainnet. We have two modes:
  1. Sepolia Testnet: Use to try out our features with no risk.
  2. Ethereum Mainnet: Aztec Alpha Mainnet carries inherent risk. We recommend treating any funds deposited here as experimental. Only use what you can afford to lose while we and Aztec work toward a stable release.
We encourage you to treat Nyx Alpha as an opportunity to test, give feedback, and help shape the direction of Nyx. In the coming months, once Nyx and Aztec are more battle-tested, both will graduate to beta. Around this point we’ll raise or remove our deposit caps.

​
What Mainnet deposit limits are in place?

We have deposit limits per connected Ethereum wallet of
  • 100 USDC
  • 100 USDT
  • 0.05 WETH
If you deposit 80 USDC, you can only deposit 20 more. When you withdraw to your connected L1 wallet, your deposit limit resets by that amount (up to the max). When you withdraw to a different L1 address, your deposit limit does not reset, so keep this in mind.

How do Aztec version migrations work?

Aztec plans to release a new, upgraded version of their Alpha Mainnet every couple of months. We have worked with them and other Aztec teams on a plan to migrate user state between these versions. What you’ll need to do after a new version launches before you can use your funds:
  1. The first time: you’ll have to remove your funds and re-deposit. We’ll create an app to help with this.
  2. Subsequent times: log into your Nyx account and initiate a migration transaction. Our UI will bring this to your attention in a straightforward way.
These migrations involve redeploying your private account on the updated Aztec version. As a result, your private account address may change. Also, your contact book will become invalid because your contacts’ addresses may have changed. You’ll need to re-add people after asking for their new address. Finally, you’ll lose your transaction history from the previous Aztec version. Migrations, while annoying for the user experience, allow Aztec to make regular, substantial improvements to security and performance.
