Convert Materium MTRM to Optimism OP

In Mirandus, players have absolute freedom of choice - there are no maps, no quest givers. Players can set out into the wilderness alone to try their fortunes against the monsters of the deep woods and dungeons, join with one of the monarchs to serve as a knight in their court, or set up shop in one of the five great citadels of the realm. Players take on the role of avatars in the world, and if desired, can purchase an exemplar avatar with powers and abilities beyond those of others in Mirandus. Player ownership of in-game assets is a central mechanic, with players being able to hold land deeds which allow them to claim parts of the wilderness and set up holdfasts ranging from small farms to massive cities. The risks of exploring Mirandus are great – but so are the rewards, for Mirandus is rich in the arcane substance Materium, a concentrated magic that allows players to channel its power to cast spells, craft the impossible, and even raise a slain hero from the dead.

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
