ECIES on a public permissionless chain has a fatal usability flaw: the recipient's private key must be passed in calldata so the precompile can perform the discrete-log unwrap. Calldata is public, so any genuinely-encrypted use leaks the private key on the first unwrap — defeats privacy. Any cosmetic use (e.g. registering the config but never calling decrypt) is a footgun waiting to fire. Brand L2 cchain.json files (hanzo/zoo/pars/spc-mainnet/testnet/devnet) were scrubbed in a prior patch; devnet/cchain.json was the lone Lux primary copy that still carried the entry. This brings devnet in line with mainnet (no eciesConfig in primary genesis) and matches the live cluster CM state (verified empty across all 3 envs). UPGRADE_NOTES.md at configs/mainnet/UPGRADE_NOTES.md documents the exclusion rationale for posterity. Removal is final — eciesConfig will not be re-added to any Lux-network chain.
Lux Network Genesis Configurations
This repository contains the canonical genesis configurations for all Lux networks.

These genesis files are used by:
luxdnode for network initializationcorethfor C-Chain configuration- Block explorers for genesis block verification
- Migration tools for state reconstruction
RPC Endpoints
- Mainnet:

Genesis Account
All networks use the same production genesis account:
| Account | Balance | Networks |
|---|---|---|
0x9011e888251ab053b7bd1cdb598db4f9ded94714 |
2T LUX | All networks |
