Aa.3 - EVM bridge design & implementation: IN PROGRESS

Complete the design and implementation of the bridge that connects Nimiq to Ethereum and other EVM-compatible networks (networks that run the Ethereum Virtual Machine). This is the asset on-ramp: the way stablecoins and other assets reach Nimiq and its faster, simpler payment experience.

Hi Richy, thanks for opening the roadmap up for discussion.

I run the ImpactZero validator and have been building small tools around NIM (nimiq.subimpact.net). One question on the EVM bridge, plus an offer to help.

Question: will the bridge also work in the other direction, NIM out to EVM chains?

The Aa.3 post describes the bridge as the on-ramp for stablecoins and other assets coming into Nimiq, which makes sense for Nimiq Pay. I could not find anything about NIM itself going out as a wrapped token (wNIM) on Ethereum, Polygon or other EVM chains.

The reason I ask: here in Malaysia every centralised exchange that lists NIM blocks local users, so right now there is no simple way for people here to buy NIM. A wNIM pool on an EVM DEX would fix that for anyone in the same position, and it would put NIM in front of DeFi users who will never open a Nimiq wallet first.

If outbound NIM is planned, it would help to know:

  1. Which chain(s) come first (Polygon, since the wallet already uses it for USDC/USDT, or Ethereum mainnet)?
  2. Roughly which phase it sits in, even without a date.
  3. How the NIM side is secured in the non-custodial design, so integrators know what they are building on.

Offer

If it fits your plans, I would be happy to help with any of these:

  • An ‘any coin to NIM’ Mini App inside Nimiq Pay, using the EVM chains Pay already exposes to Mini Apps.
  • Testing on testnet, or building parts of the outbound side, possibly through a Council proposal if that makes sense.

I would rather build on the official bridge than create a separate wrapped NIM that splits liquidity, so your answer decides what we build next.

Thanks!
