IMPLEMENTED

TWO LINE problem statement

Adapt Hyperlane codebases and bring to Dymension to enable seamless bridging between external ecosystems and rollapps.

How does this solution solve the problem?

There are three PRs

• Hub: https://github.com/dymensionxyz/dymension/pull/1797
• Hyperlane cosmos module: https://github.com/dymensionxyz/hyperlane-cosmos/pull/3
• Hyperlane external tooling and contracts codebase: https://github.com/dymensionxyz/hyperlane-monorepo/pull/2

Together the PRs add

• Hyperlane cosmos module integration to hub: it allows adding and receiving hyperlane messages and token transfers to an sdk.Address
• Hub transfer hooks: allows arbitrary hooking onto eibc transfers and hyperlane transfers, which can forward based on memo field.
