This funding aims to advance [blockchain](https://iq.wiki/wiki/blockchain) interoperability by bridging IBC and non-IBC chains.  \n  \nIn January 2024, Polymer secured $23 million in Series A funding. This round was co-led by Blockchain Capital, Maven 11, and Distributed Global, with additional contributions from [Coinbase](https://iq.wiki/wiki/coinbase) Ventures, Placeholder, DCG, North Island Ventures, and Figment Capital. The funds are intended to support the development of [Ethereum's](https://iq.wiki/wiki/ethereum) interoperability hub and the PolymerDAO governance model.[\\[10\\]](#cite-id-2727izkhxu1)[\\[11\\]](#cite-id-ifbv9pm0oo)  \n  \n# Partnership Program  \n  \nThe Polymer Partnership Program aims to advance [blockchain](https://iq.wiki/wiki/blockchain) interoperability by involving contributors from various ecosystems. Individuals can start as Early Adopters by participating in the Incentivized Testnet (PIT), with the possibility of earning rewards. Those showing significant engagement may be invited to the Insiders group, where they gain additional support and access to user research.  \n  \nThe program also includes a Launch Partners tier for industry leaders.
