Orbiter Finance

Orbiter Finance is a decentralized cross-rollup bridge protocol designed to move assets between Layer 2 networks quickly and cheaply. Its main goal is to enable secure, decentralized cross-rollup transfers within the Ethereum ecosystem, improving interoperability between mainnet and rollup layers. Instead of routing every transaction through smart contracts on both ends, Orbiter transfers occur directly between user wallet addresses, keeping fees low and speeding up the process. Think of it as a highway on-ramp that bypasses the congested main road entirely.

Since its launch in April 2021, Orbiter Finance has gained recognition in the DeFi market for quick, cost-effective transactions and an efficient user experience. What began as a bridge for a few Ethereum Layer 2 networks has grown into one of the most widely used cross-chain routing platforms in crypto. According to official data, Orbiter Finance now supports over 19 networks, has more than 3 million users, processed 12 million transactions, and reached a total transaction volume of $960 million USD.

The platform’s core use case is solving a persistent pain point in multi-chain crypto: moving assets from one network to another without paying a fortune or waiting too long. Orbiter connects over 70 networks to move assets seamlessly. Its technical approach combines an optimistic security model with zero-knowledge proof arbitration for speed and cost efficiency. For everyday DeFi users, this means bridging from Arbitrum to Optimism in seconds instead of minutes and paying a fraction of what official bridges charge.

Orbiter supports many networks including Ethereum, zkSync Era, zkSync Lite, Linea, Mantle, Base, StarkNet, opBNB, Scroll, Arbitrum, Arbitrum Nova, Loopring, Optimism, Polygon, Polygon zkEVM, BNB Chain, Zora, ImmutableX, BOB, BEVM, Bitlayer, and BSquared. It also handles non-EVM Layer 2 and Layer 3 networks, making it attractive for developers building across diverse blockchain environments. Its ability to quickly access mainstream projects like Solana and emerging ones like Abstract and Story, combined with transfers completing in 10 to 20 seconds, drives continued user growth.

Under the hood, Orbiter’s security model relies on three components: a Maker Deposit Contract, an Event-Bound Contract, and a Simplified Payment Verification scheme. Makers are liquidity providers who complete transfers on the destination chain on behalf of senders. Orbiter’s cross-rollup design was built on an optimistic principle that assumes all transactions are valid, with an Arbitration Mechanism in place so users can challenge the result of any failed or disputed transfer. This structure means users don’t trust a central operator; they trust the math.

Beyond simple bridging, Orbiter has expanded its scope significantly. The platform is developing infrastructure for direct Rollup-to-Rollup communication, an Omnichain Infrastructure that breaks barriers between blockchain networks and reduces reliance on Ethereum Layer 1. The project also builds tools like OpenClaw MCP, a developer toolkit for cross-chain automation that gained over 1,000 GitHub stars in one day, signaling developers see Orbiter as serious infrastructure, not just a bridge UI.

Orbiter Finance closed its first funding round on November 29, 2022. That round drew participation from Tiger Global, A&T Capital, StarkWare, Cobo Ventures, Mask Network, and others, with Ethereum co-creator Vitalik Buterin personally donating 16 ETH to the project. Buterin’s involvement was more than symbolic; it signaled that Orbiter’s technical approach to Ethereum Layer 2 interoperability had credibility at the highest level of the ecosystem.

In 2023, Orbiter completed its Series A financing, led by OKX Ventures, with participation from Redpoint China, Hash Global, Skyland Ventures, and others. As of 2024, additional backers include Mirana Ventures and Tiger Global Management across a total of three private funding rounds, though the exact amounts raised have not been disclosed publicly. OKX Ventures founder Dora Yue publicly praised the team’s continuous product upgrades and commitment to decentralization, describing Orbiter as crucial infrastructure for the Layer 2 ecosystem.

On January 17, 2025, Orbiter Finance announced the release and airdrop of its native OBT token, which is used for governance voting and staking. The airdrop rewarded users who had accumulated O-Points, Orbiter’s internal activity-tracking system that logged bridging volume, token diversity, transaction frequency, and engagement with platform tools. The OBT token facilitates governance and staking and supports the protocol’s progressive decentralization, meaning OBT holders can vote on decisions like fee structures, supported chains, and node operations. Essentially, OBT gives active users a stake in how the protocol evolves.

OBT tokens are available on centralized cryptocurrency exchanges for standard spot purchases. If you want to buy or sell large amounts, acquire locked tokens, or deal in SAFT notes, the Acquire.Fi OTC and Secondaries Marketplace is designed for that.

If you want to buy Orbiter Finance tokens OTC, you have two paths on Acquire.Fi. You can browse existing listings and engage with sellers directly, or you can submit a new Buy listing at your preferred valuation and token amount. The platform matches you with counterparties who meet your terms.

If you want to sell Orbiter Finance tokens OTC and exit an existing position, the process works the same way in reverse. You can engage with active Buy listings already on the marketplace, or you can submit a new Sell listing at the price and size you want. Either way, Acquire.Fi handles what comes next.

Once a match is identified, the Acquire.Fi team conducts background checks on both sides, sends NDAs, and then formally introduces buyer and seller. Buyer and seller are responsible for their own due diligence and for settling payment. Acquire.Fi is not a broker-dealer, but the team actively assists throughout the process to make sure the deal closes. For any large OBT position, whether you’re accumulating or exiting, that support structure makes a meaningful difference.
