7/7 Don’t miss what’s next, click ‘interested’ on the Discord events tab to catch the next call:

6/ uname also launched, the Universal Web3 Identity. unames will be usable across the growing Union network, letting you connect wallets and sites with a single name. Follow @uname_domains for updates.

5/ Union has been here, there, and everywhere on CT lately, featured on @kucoincom #KuCoinFireSideChat, Union's first Korean AMA hosted by @Cryptowombat125, Block by Block with @shmula, and @accountantquits. Not to mention the weekly Union Hall Cast—tune in this week for some

4/ Union is adding support for @Base, creating a trustless, zk-powered connection for frictionless crosschain liquidity. Base apps get direct access to IBC, MoveVM, and more, with max security and sub-second interoperability.

3/ Union launched its mainnet. During the Community Call, the core team shared more details about the launch, highlighting what went well, what could have been improved, and answering your questions. For the mainnet rundown, watch from this timestamp ↓ https://t.co/OQLhEeYq6A

2/ Union debuted at Bitcoin Asia in Hong Kong. @0xkaiserkarel & @Gandalf_NFT discussed bridging BTC to Ethereum, Solana, and Babylon with ZK + smart contracts. With @AuroBTC, liquid staking & sustainable yield were highlighted.

1/ Union released App v4, combining testnet and mainnet transfers into a single app. It merges https://t.co/FoRLvUjzDj and https://t.co/6KQsquUml1 into one interface. Solver-based assets like U and eU are now supported. These assets simplify crosschain transfers and let U have

6/6 App v4 combines the best of App v3 and the BTC app, and this is just the beginning—more improvements and features are coming. Check it out ↓ https://t.co/FoRLvUjzDj

5/ SDK v2.0 also improves data handling and post-submission stability, reducing failed transactions and making the experience more reliable for both users and developers.

4/ Under the hood, App v4 uses the rewritten TypeScript SDK v2.0, bringing more secure and correct payload encoding. This helps prevent errors, protect assets, and ensures transactions are processed accurately across chains.

3/ Moving, managing, and integrating assets across chains becomes faster, more reliable, and easier for both users and protocols. Solver-based assets also allow configurable fungibility between routes, solving the diamond-shape problem for asset transfers.

2/ Solver-based assets like U and eU are now supported. These assets simplify crosschain transfers, and let U have the same 0xba5ed address on all EVM chains. Users specify desired outcomes while the system handles execution.

1/ App v4 merges https://t.co/FoRLvUjzDj and https://t.co/6KQsquUml1. Users no longer need to switch between apps or wallets—everything runs in a single, unified interface, which simplifies transfers, crosschain interactions, and asset management.

Before mainnet, Union released App v4. It combines testnet and mainnet transfers into a single app...but that's not all. App v4 also adds U and eU support, a rewritten SDK, and BTC app integration. Here’s what makes it a true upgrade ↓
