Dymension enshrines IBC as the canonical bridge for RollApps. This keeps user bridged funds secured in an escrow account secured by the Dymension blockchain rather than a smart contract.


IBC (Inter-blockchain communication) is a message passing protocol that acts as the standard bridge for RollApps. Bridging is handled through the x/ibc module of the RollApp which enables minting, locking, and burning fungible tokens.

Bridge functionality is included out-of-the-box with RollApps, meaning a RollApp has immediate access to large amount of liquidity such as native USDC, USDT, and more.


eIBC is a protocol built on top of IBC that allows users to transfer out of RollApps without waiting for dispute periods.
