Privacy rails
Every slice is funded through a privacy rail chosen per chain, so no deposit links it to you or to the other slices.
Why funding needs a rail
Fresh accounts are only unlinkable if their money is. If every slice were funded from your main wallet, one look at the deposits would tie them together. A privacy rail breaks that trail: each account is funded so that no deposit links it to your main wallet or to the other slices.
Candidate rails
Rails are chosen per chain. The candidates are:
- Railgun
- WhereEthereum, Arbitrum, Polygon, BNB Chain
- RoleShielded pool for funding slices
- Privacy Pools
- WhereEVM chains
- RoleShielded pool for funding slices
- NEAR Confidential Intents
- WhereCross-chain
- RoleFunding slices on one chain from assets on another
- Solana shielding pools, such as Umbra
- WhereSolana
- RoleShielded funding for Solana venues
The rail used on each chain is announced with each venue.
Cross-chain funding
Fund slices on one chain from assets on another without a public bridge trail. Faster rails are one of the $MUTEX tier benefits.
