Convert Optimism OP to Staked YUSD SYUSD

Optimism is a network of chains called the Superchain, built on the open-source OP Stack. OP Mainnet was the first chain, with several others now operating on the OP Stack architecture, including Base (by Coinbase), Unichain (by Uniswap), Ink (by Kraken), and World Chain (by Worldcoin). The OP Stack serves as a framework for Ethereum Layer 2 chains and supports significant L2 activity. Every OP Chain in the Superchain contributes back to the Optimism Collective and all chains follow a standardized revenue-sharing model: the greater of 2.5% of total chain revenue or 15% of onchain profit (defined as fees minus L1 gas costs) is paid back to the Optimism. By aligning economic incentives across many chains, Optimism aims to transform Ethereum scaling into a sustainable flywheel by delivering fast, low-cost transactions while reinvesting in the future of the ecosystem. OP holders participate in governance to shape protocol upgrades, funding decisions, and more

Overview sYUSD is the yield-bearing, staked version of YUSD. When you deposit YUSD into the staking contract you receive sYUSD, which: Represents your proportional share of the staking pool. Automatically accrues BTC funding-rate yield. Appreciates in value relative to YUSD over time. Launch exchange rate: 1 sYUSD = 1 YUSD Afterwards: 1 sYUSD > 1 YUSD as rewards accumulate. The StakedYUSD smart contract implements the ERC4626 Token Vault standard for composability. This popular standard is widely used for onchain reward-accruing; thus, it is expected that other user interfaces beyond the Aegis.im dAPP may likely support YUSD staking in the future. Various deposit and redeem functions are exposed, enabling staking with or without a slippage threshold, and with or without an ERC2612 Permit signature authorizing the transfer of YUSD.
