open source. we’re building base on the OP Stack — which means that if you want to contribute, you can! you can review the code and start contributing here. we’ll be open sourcing as much as possible, so more people can get involved.

Optimism is an Ethereum scaling solution that enables anyone to execute any vision on an open source protocol that will never be captured by private interests. We’re building this technology as a public good, in order to fundamentally change the relationship between companies and their users.

From code to ethos, we are Ethereum-aligned. By operating as a Public Benefit Corporation, we align private incentives with public good and create a positive-sum economic model that provides a sustainable future for the internet.

Today, the most pressing bottleneck to Ethereum and crypto’s growth is its performance and scalability. We are building the most elegant solution to this problem. We do this out in the open because we believe in open source and its ability to accelerate innovation.

To date, we have raised $178M. Both series A and B were led by Andreessen Horowitz and Paradigm.

We are actively hiring for the roles listed here: All open roles are listed here:

Join us in scaling Ethereum and empowering the creators of public goods! :)

Optimism's Bedrock contracts have pretty good examples - https://github.com/ethereum-optimism/optimism/tree/develop/packages/contracts-bedrock

Perp-maker is an open-source market-making template for Perpetual Protocol v2, the most popular dApp on Optimism (a layer-2 scaling solution for Ethereum). Anyone can use or modify the template to facilitate trades on the protocol and earn fees.

Except that anyone with a minimal involvement with Ethereum already knows that the base layer is not meant to be used on day-to-day operations.

We already learned about the decentralization trillema. The strategy to scale Ethereum through will be through the adoption of "layer-2" systems, where users are expected to be doing their transactions and avoid these costly transactions altogether.

There are roll-ups already dealing with NFT marketplaces [0]. There are roll-ups that can execute any type of ethereum smart contract [1] [2]. There are payment channels that allow completely decentralized and gas-less transfers of ERC-20 tokens [3].

Boba is a compute-focused L2. We believe that L2s can play a unique role in augmenting the base compute capabilities of the Ethereum ecosystem. You can learn more about Turing hybrid compute here. Boba is built on the Optimistic Rollup developed by Optimism. Aside from its main focus, augmenting compute, Boba differs from Optimism by:

The Across bridge is the fastest, cheapest, and most secure bridge between L1 and L2 (and soon between L2 and L2 hopefully). Across has integrated with the canonical bridges of Boba.network, Optimism.io, and Arbitrum.io, with more to come. Go take it for a spin and save yourself some ETH here: https://across.to/

zkSync is a ZK rollup, a layer-2 protocol that uses cryptographic validity proofs to provide scalable and low-cost transactions on Ethereum.

As a leading cryptocurrency exchange, BingX is committed to providing its users with fast, secure, and innovative trading services. In its latest effort to further develop its spot trading capabilities, BingX has announced the integration of zkSync Era to support online crypto deposit and withdrawal. zkSync Era is a Layer-2 protocol that scales Ethereum with cutting-edge ZK tech. zkSync uses zero-knowledge proofs (zk-proofs) to enable fast and cheap transactions. With zkSync, users can deposit and withdraw funds to and from the main Ethereum network in a faster and easier way, without having to wait for long confirmation times or pay high gas fees. BingX's integration with zkSync Era enhances the spot trading experience. Without registering a separate private key, users are able to do secure and near-instant online deposits and withdrawals of cryptocurrencies. BingX has announced that CHEEMS USDT is now available for trading on its platform. In addition to this integration, BingX has launched its BRC20 trading zone and supports popular trading pairs such as VMPX/USDT, MEME/USDT, PEPE/USDT, PIZA/USDT, NALS/USDT. Meanwhile, BingX has listed Ordinals ($ORDI) on May 8th, and the trading pair is ORDI/USDT. BingX took the lead to support Ordinals protocol and listed $ORDI on its platform. Ordinals protocol is a DeFi project that aims to create a seamless and user-friendly platform for derivatives trading. This project leverages smart contract technology to enable trustless and transparent trading of derivatives products. With the listing of $ORDI, BingX users will be able to trade the token against major cryptocurrencies such as Bitcoin (BTC) and Ethereum (ETH). This will provide users with more options to diversify their investment portfolios and potentially benefit from the growth of the Ordinal protocol. "The integration of zkSync Era and support of BRC20 tokens are part of our continuous efforts to enhance our spot trading services and support the growth of the blockchain industry," said Elvisco Carrington, PR and Communications Director of BingX. "We are thrilled to offer our users a more streamlined and cost-effective way to conduct spot trading over a wider range of cryptocurrencies and tokens. As part of our ongoing commitment to offering access to the most promising and innovative projects in this ecosystem, BingX looks forward to providing a better trading experience for users and continuing our role as a leading innovator."
