Umi Containers

Umi Containers are the on-chain building block that makes cross-chain wallets and assets discoverable, verifiable, and easy to use across DApps.

A Container is a Sui object you own that acts like a vault for Ika shared dWallet caps and a ledger for the assets associated with them. Containers exist to create a stable, indexable anchor on Sui that applications can follow to keep a user’s cross-chain inventory up to date.

When you deposit a cap into a container, you’re doing two things at once:

• Locking signing authority so the external wallet can’t be actively used while it’s being indexed

• Creating a stable, indexable anchor that DApps can rely on for inventory discovery and verification

This is what makes cross-chain assets feel native: the container becomes the canonical “home” for wallets and the assets they control.

Containers are:

• a custody vault for Ika shared dWallet caps

• an indexable anchor for cross-chain inventory

• the foundation for verification flows DApps can depend on

Containers are not:

• a bridge

• a wrapped-asset standard

• a guarantee that assets exist without verification
