Union Token Surpasses 300 Million Transactions on Testnet Rollout

Union, the native gas token of the network, serves three main functions within the Union ecosystem. As a gas token and fee market, it facilitates transactions on the platform. Additionally, it enables network security through delegated Proof-of-Stake (PoS) consensus and cross-chain governance.

The project has a capped supply of 10 billion tokens with an initial annual inflation rate of 6%, which decreases by 10% each year until reaching a long-term issuance rate of 2%. Union was launched in April 2023 by the founding team of six engineers, including CEO Karel and CTO Cor. They previously worked on CosmWasm and implemented IBC within DotSama to create the first trustless bridge between Kusama and Polkadot.

The project has made significant progress since its inception. In June 2024, a phased testnet rollout began, with the ninth and final testnet crossing over 300 million transactions in August 2025. During this time, Union raised $16M. A limited mainnet was launched in April 2025 to expand interoperability in the BTCfi space via partners such as Babylon, BOB, Corn, Lombard, Bedrock, and Solv.

Union has become a Bitcoin Supercharged Network (BSN) and introduced Auro BTC (auBTC), its native, cross-chain yield-generating product. The project has gained a global community following across social channels, events calendar, and through its Wandering Whale Sharks and ZK Goblin Mode NFTs.
