Sovryn is a multi-chain dapp that currently gives users two complementary options: Rootstock and BOB (Build on Bitcoin).
Rootstock allows users to buy and sell BTC; trade BTC on margin; borrow, lend, and yield-farm BTC and other assets; and obtain bitcoin-backed stablecoins in a noncustodial and permissionless way. Sovryn uses a pegged form of BTC on the Rootstock network called RBTC. In addition, Sovryn uses the native SOV governance token for participating in the bitocracy and for various rewards in the system.
BOB is a hybrid Layer-2 rollup with the goal of providing the security of bitcoin and the programmability of Ethereum. It is currently an optimistic rollup on Ethereum that provides bridges to/from Ethereum and other EVM chains that allows low gas fees and easy access to ERC-20 tokens and potentially a great deal of liquidity from the Ethereum ecosystem. The roadmap includes a bridge to bitcoin and an optimistic rollup powered by BitVM.
