Get the extension What is IBC in Cosmos?
IBC (Inter-Blockchain Communication) is the protocol Cosmos chains use to send tokens and messages to each other, over a port and a channel opened between two chains. A token that crosses over appears on the other side under an ibc/... denomination.
Why it matters
Choosing the wrong channel, or sending to an address on the wrong chain, can leave tokens stranded. Each chain has its own address prefix (cosmos1..., osmo1..., inj1...), all derived from the same key.
How Locker Protocol Wallet handles it
Locker Protocol Wallet covers the Cosmos chains it supports, among them Osmosis, Injective and Stride, from one recovery phrase. The Vault decodes the SignDoc itself and shows every message before you sign.
Questions
What is an IBC denom?
The name a token carries on a chain it was sent to, such as ibc/27394FB0... for ATOM on Osmosis. It is a hash of the path the token travelled.
Is IBC a bridge?
It plays the same role between Cosmos chains, but it is a native protocol checked by each chain's light clients rather than a separate service holding the funds.
