OneBalance

OneBalance is a cross-chain settlement infrastructure company that built tools to abstract away blockchain complexity for application developers. Its core thesis is that the proliferation of Layer 1 and Layer 2 networks has splintered liquidity and created friction — users are forced to manage balances across multiple chains, choose bridges, acquire chain-specific gas tokens, and wait for cross-chain finality before transactions complete. OneBalance was built to remove that friction at the infrastructure level so that developers can offer users one-click experiences across any chain without exposing them to the underlying mechanics.

Resource Locks: The Core Mechanism

The foundation of OneBalance is a concept called Resource Locks, which the team introduced to the broader Ethereum research community in a post on ethresear.ch. Resource Locks solve the primary technical obstacle in cross-chain settlement: a system that wants to move assets from one chain to another must ordinarily wait for source-chain finality before releasing funds on the destination chain, which introduces latency, uncertainty, and the risk of reverts.

Resource Locks work by temporarily locking a specific asset and amount in the user's account along with a cryptographic "credible commitment" — a signed statement of intent tied to specific conditions, such as execution on the destination chain or an expiry time. Because the commitment is verifiable, solver networks can release funds on the destination chain immediately after seeing the signature, without waiting for the origin chain to confirm. The lock prevents double-spending by guaranteeing that the locked funds cannot be moved until the commitment resolves. The result is instant cross-chain execution that is 40% faster than traditional cross-chain routes, according to the company, without requiring any chain upgrades or special infrastructure on the networks being connected.

Solvers — specialist actors similar to those in intent-based bridge protocols — read the credible commitments and compete to fulfill user intents. The solver that executes first captures the fee. OneBalance's delivery-versus-payment model means execution is guaranteed without reverts, and because the price is agreed upfront, users are not exposed to MEV extraction or unpredictable slippage.

The OneBalance Toolkit

OneBalance packaged Resource Locks into a developer product called the OneBalance Toolkit, an API platform designed for application developers to integrate cross-chain execution into their products without building the underlying infrastructure. The Toolkit supported:

• Unified balances: token holdings fragmented across chains presented as a single spendable balance per asset
• Gas abstraction: gas fees paid using the input token rather than chain-specific native tokens
• Chain abstraction: end users interact without selecting networks, bridging, or managing chain-specific accounts
• Arbitrary calldata: developers can execute any on-chain action, not just token swaps

Integrations with embedded wallet providers Privy and Turnkey allowed developers to deploy the Toolkit on top of their existing wallet infrastructure. The September 2025 addition of EIP-7702 support extended chain abstraction benefits to Externally Owned Accounts within embedded wallets, bringing smart-contract-wallet UX to the most common account type without requiring users to migrate to a new wallet format.

The Toolkit covered major EVM networks including Ethereum, Arbitrum, Base, and Optimism, with Bitcoin support added in early 2025. Solana support was in progress at the time of the last published update, with swap functionality live and multichain calldata execution planned.

Real-World Deployment: Dexari

A published case study demonstrates the Toolkit's application at scale. Dexari, a mobile-first trading app for Hyperliquid, used OneBalance to handle all cross-chain deposit and settlement logic. Accessing Hyperliquid ordinarily requires bridging assets to Arbitrum and then depositing through a separate step — a multi-stage process incompatible with a streamlined mobile experience. OneBalance consolidated that into a single user action: users hold stablecoins on any supported network, and OneBalance presents their aggregate balance as one number they can trade from immediately.

Within Dexari's first month of launch, users executed over $1.375 billion in trading volume across more than 1,600 active traders. The Dexari team reached full production in under two weeks of integration work.

Other closed-beta partners at the time of the $20 million funding announcement included DSX (building a self-custodial trading platform), VOOI (a chain-abstracted decentralized exchange), Spritz Finance (crypto-to-traditional finance payments), and Kii (an FX layer for stablecoins in emerging markets).

Funding and Team

OneBalance raised $5 million in an angel and community round announced in August 2024, anchored by cyber•Fund and backed by individual angels from Consensys, Wintermute Ventures, Curved Ventures, Breed VC, Anagram, and Credibly Neutral, along with contributors from Yearn Finance, Across, Privy, WalletConnect, LiFi, and other projects.

In June 2025, OneBalance announced a $20 million Series A round co-led by cyber•Fund and Blockchain Capital, with additional participation from Bybit's Mirana Ventures and L2IV. The full investor list across both rounds also includes Curved Ventures, Breed VC, Anagram, Credibly Neutral, Consensys, Wintermute Ventures, and Cobie.

The founding team comes out of Flashbots and related research:

• Stephane Gosselin (CEO): co-founder and architect at Flashbots, designer of ERC-1400, previously at Frontier Research
• Daniel Worsley (COO): Flashbots steward and operations lead, previously built LocalCoinSwap and contributed to Frontier Research
• Ankit Chiplunkar (CTO): PhD in Aerospace Engineering, previously scaled systems at Coinbase and TokenAnalyst

The broader team includes contributors from Aragon, Polygon, the Ethereum Foundation, RhinoFi, Argent, and Nansen.

Current Status

OneBalance went through a significant product transition in 2026. The OneBalance Toolkit API was deprecated on May 18, 2026. OneApp — the company's own consumer-facing trading application built on top of the Toolkit to demonstrate Resource Locks in a retail context — was shut down on June 30, 2026, with the company announcing that users should withdraw funds before the deadline. As of July 2026, the main onebalance.io website remains active and continues to market settlement infrastructure to enterprise clients across three segments: exchanges and brokers, fintechs and neobanks, and institutional custodians. The company reports $3 billion or more in transaction volume settled across its history, 50-plus supported blockchains, and 99.99% uptime over the preceding six months. Official developer documentation for the Toolkit API is no longer available.

The Resource Lock concept that OneBalance introduced has been recognized as a component of the broader Ethereum interoperability roadmap, with active development from teams across the ecosystem. Whether OneBalance continues to operate Resource Lock infrastructure under a private enterprise model or is winding down broader operations was not publicly disclosed as of the deprecation announcements.
