The Polkadot community is discussing a new proposal to develop a bridge connecting Polkadot and Cardano. Unifires agent Felix revealed that a proposal for a Cardano-Polkadot light client side and NFT exchange bridge has been submitted and is planned to be submitted to Polkadot's OpenGov. Tommi Enenkel (Alice and Bob), lead ambassador of Polkadot, said that this can be achieved by validating the Beefy proof on Cardano. The proposal has received general support from the community. In addition, SnowBridge launched a bridge connecting Polkadot and Ethereum on June 20. SnowBridge uses first-party signatures from validators to support the transfer of ERC20 assets between the two networks, with the expectation of enabling arbitrary messaging and initiating liquidity programs in the future.
