Stargate is a native asset bridge built on LayerZero that enables cross-chain liquidity transfers. Applications, such as decentralized exchanges (DEXs), can integrate Stargate to facilitate cross-chain transactions at the application level. STG holders can stake their tokens to receive veSTG, the unit of Stargate governance voting power. A user’s veSTG balance decays linearly as the remaining time until the staked or locked STG unlock decreases. One-sixth of non-STG transaction fees (1 bps) are also allocated to veSTG holders.

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
