IBC Eureka is live — enabling fast, secure Ethereum ↔ Cosmos bridging.

IBC Eureka offers fast, affordable, 1-click transactions between Ethereum and Cosmos chains. It's also the canonical usage of the v2 of @ibcprotocol.

Key product info🧵

[Cosmos - The Interchain ⚛️ @cosmos]

IBC Eureka is LIVE!

→ Transfers faster than Ethereum finality
→ Send from Ethereum for as low as $1
→ 1-click experience that supports your favorite wallet

Starting with Ethereum, @cosmoshub, @babylonlabs_io, Cosmos chains,
and soon, IBC everywhere🧵

Companies using the Cosmos stack: the stack's security processes have important updates.

Here are the key changes:

- Patching will now be an entirely private process

- A more comprehensive security contact policy

- A new code of conduct for Cosmos repositories, including clarifications on the disclosure policy

- Changes to the bug bounty program to prioritize critical vulnerabilities

Together, these changes will help to improve security practices and harden the stack code to provide greater predictability and transparency for users.

Cosmos stack users are encouraged to join the security contact list to receive security information and patches.

2️⃣ Benefits to Developers

✦ Custom metadata and token naming on deployment
✦ Easier contract verification on Etherscan
✦ Increased trust in the bridged asset
✦ Complete ownership and control over the ERC20 asset.

These changes may make it easier to list custom ERC20 assets on CEXs.
