    About Optimism

    Optimism (OP Mainnet) is a Layer 2 optimistic rollup chain on Ethereum that processes transactions off-chain and posts batched data to L1 for settlement. The rollup inherits Ethereum security through fraud-proof verification, where invalid state transitions can be challenged within a withdrawal period. Developers deploy unmodified Solidity contracts with reduced gas costs while users access decentralized applications at significantly lower fees than mainnet.

    Fireblocks Off Exchange
    Custody Technology Provider

    Fireblocks Off Exchange is a settlement service that allows trading firms to keep collateral in Fireblocks-secured custody while trading on partner exchanges, rather than depositing funds directly onto exchange accounts.

    Nexus is a modular smart account platform that replaces traditional externally owned wallets with programmable, ERC-4337 and ERC-7579 compliant accounts. It provides custom authentication, session-based permissioning, and gas abstraction so applications can sponsor fees or let users pay gas in any token. Built-in smart sessions let users delegate scoped, revocable permissions to bots or AI agents with spending limits and contract whitelists, enabling automated onchain actions without exposing full account control. The account is compatible with EIP-7702, allowing existing wallets to gain smart account capabilities, and deploys with unified addresses across multiple blockchains.
