Osmosis, the largest decentralized exchange (DEX) on Cosmos, is bringing Bitcoin (BTC) to the inter-blockchain communications (IBC) protocol in collaboration with Nomic and Kujira. Users can transfer Bitcoin to the Cosmos network via Osmosis' Nomic bridge for a 1.5% transaction fee and receive Nomic Bitcoin (nBTC) on a one-to-one basis. The nBTC Interchain Upgrade is set to launch on October 27 and activate on October 30. Users can also send BTC to Kujira's Sonar wallet address and self-custody their nBTC. The nBTC can be used as collateral to mint Kujira's native stablecoin USK and for borrowing and lending within the ecosystem.
