Upcoming change to the ZetaChain ERC-20 Custody Contracts on all connected chains 🚨

Updated ERC-20 Custody contracts will go live for ZetaChain on November 13th and 14th. The new ERC-20 Custody contract address for all EVM chains will be: 0x0Bad40D9e9C369f2223c835E108f43a45fd223B5. The contract interface remains the same so no changes other than the contract address are needed.

How to Upgrade to the new ERC-20 Custody Contract Address:

If you have hardcoded the address anywhere in your dapp you'll need to make the change manually at the correct time for each external chain. See https://status.zetachain.com for the specific maintenance window for each connected chain.

If your dapp queries the address dynamically from the /zeta-chain/observer/get_chain_params endpoint, then your dapp will pickup the change automatically and no action is needed.

If you use the Protocol-Contracts NPM Package you will need to update to the latest version during the maintenance window.

The migration to the new address will be staggered across each connected chain. See https://status.zetachain.com for the schedule maintenance windows. When the migration begins, any transactions sent through the old ERC-20 Custody contract will be reverted, so it's essential to switch to the new address.

Gateway Contracts Deployed on Testnet! 🌏

We’re excited to announce that the Gateway contract has been successfully deployed on the ZetaChain testnet and connected chains! 🎉

The Gateway is a powerful interface serving as a unified entry point for seamless interactions between contracts on connected chains and universal apps on ZetaChain. This deployment marks a significant step forward for developers building omnichain applications.

Gateway Addresses (on testnet):

ZetaChain: 0x6c533f7fe93fae114d0954697069df33c9b74fd7
EVM Chains: 0x0c487a766110c85d301d96e33579c5b317fa4995
Solana: ZETAjseVjuFsxdRxo6MmTCvqFwb3ZHUx56Co3vCmGis

Special Developer Office Hours This Friday! 🗓️

This Friday, we’re hosting a special edition of Developer Office Hours, and you’re invited to dive deep into some of the latest bleeding-edge features on ZetaChain! 🚀

Here’s what we’ll cover:

🔐 Authenticated Calls with ZetaChain’s Gateway
We’ll introduce Authenticated Calls, an exciting upcoming feature allowing cross-chain calls with embedded sender information. This will open up new possibilities for secure and seamless inter-chain interactions.

🌠 Universal NFT Tutorial Preview
We’ll explore the new NFT tutorial that uses Authenticated Calls to create a Universal NFT—transferable across ZetaChain and any connected chains!

🏗️ Pre-Release Localnet Walkthrough
We’ll use the pre-release version of localnet, which already supports this Gateway functionality, so you can get hands-on experience with these features before they hit testnet.

This is a chance to experience the latest ZetaChain capabilities, experiment with features not yet available on testnet, and be part of building the future of blockchain interoperability. Don’t miss out on this opportunity to get hands-on with the future of ZetaChain! See you there! 🙌

Updated ERC-20 Custody Contract on Testnet 🚨

We’ve deployed an updated ERC-20 Custody contract on ZetaChain testnet. The new contract address on all EVM chains is:


0xd80be3710f08d280f51115e072e5d2a778946cd7

⚠️ Please note: This update is testnet-only. No actions required on mainnet.

The migration to the new address will take place early next week, so make sure to update your configurations and integrations accordingly. After the migration is complete, any transactions through the old ERC-20 Custody contract will be reverted, so it's essential to switch to the new address.

Gateway Contract Launch Update 🚨

As part of the upcoming Gateway Contract launch, we want to inform you that a new ERC-20 custody contract will be deployed to a new address.

🔄 What's New? The new ERC-20 custody contract is fully backwards compatible, so your applications will continue to function as expected. However, once the migration is complete, the old ERC-20 custody contract will no longer be functional, and any transactions sent to it will safely revert.

🚧 What You Need to Do: Please prepare your applications to be updated with the new ERC-20 custody contract address.

📅 The new address will be published later this week, so stay tuned!

Let us know if you have any questions.

Calling All Developers! 📣

We have two exciting updates and need your feedback to improve the developer experience:

🧩 Interface for Arbitrary Calls in Protocol Contracts:

We're enhancing how the call function handles regular and arbitrary calls, making it more intuitive and user-friendly. Several options are on the table to simplify the process, and we need your input!

👉 Check out https://github.com/zeta-chain/node/pull/2958 and share your thoughts on the best approach for this interface.

🌐 Proposed Standard Memo Format for Non-EVM Chains:

To provide a consistent cross-chain experience, we're proposing a standard memo format for inbound transactions on non-EVM chains. This ensures seamless functionality across both EVM and non-EVM environments.

👉 Dive into the details https://github.com/zeta-chain/node/pull/2963 and let us know what you think!

Your feedback is key to shaping these updates. Don’t hesitate to jump into the discussions and share your insights! 💬
