Composable Finance Part 1: Unlocking Cross-Chain, Cross-Layer DeFi on Polkadot

Jorrin Bruns (Support Engineer, Parity Technologies) is joined this week by 0xbrainjar, founder and CEO of the Polkadot parachain Composable Finance. Composable and sister parachain Picasso on Kusama allow smart contracts built on different languages and different chains to connect, enabling cross-chain swaps and more. By simplifying and unifying DeFi (Decentralized Finance) with new interoperability standards, the project is accelerating this technology into the mainstream. This talk covers Composable's solutions for developers and end users. 0xbrainjar describes building with Substrate and the new pallets they created, the native functionality of Composable and Picasso, and the various products and DeFi primitives they offer. Additionally, 0xbrainjar discusses cross-layer NFT transfers, building oracles for price manipulation resistance, achieving protocol-owned liquidity, bootstrapping DeFi and what could be considered ‘DeFi 3.0'.
