About GasHawk
GasHawk is a transaction landing service for Ethereum that sits between wallets and the chain. A user signs a transaction and hands it to GasHawk's RPC proxy, which watches base fee trends under EIP-1559 and historical data to broadcast inside a chosen window of anywhere from 30 seconds to a full day; if the deadline arrives first, the transaction is sent at the maxBaseFeePerGas the user set, so it does not get stuck. The payload cannot be altered, private keys never reach the service, and a queue manager handles retries and replacements. Optional private routing through Flashbots Protect or MEVBlocker reduces sandwiching and front-running.
Customers are wallets, dApps, exchanges, custodians and Layer 2 operators that submit in bulk through an SDK and REST endpoints, and more than 30 wallets including MetaMask and Rabby can add the RPC in one step. Unlike gas trackers that only publish market data, it submits the transaction itself, and unlike a generic RPC it adds queuing, retries and fee forecasting. Savings depend on how much the base fee moves, coverage is limited to EVM chains, and MEV protection relies on the small set of relays named above.
GasHawk was founded in 2022 as an Ethereum gas fee optimization tool, helping users save 25-40% on non-urgent transactions through prediction and smart execution. In September 2024, it completed a $1.6 million Pre-Seed round with participation from 3SE Holdings, AVID3, Artemis Capital, AppWorks, RedBread Ventures, Alchemy, etc., to expand its transaction-layer IP and build new services around Atomic Unit.
Earlier, the project received an ENS public goods grant and had completed multiple rounds of 51% fee reimbursements to users, onboarding over 660 individual users, validating its non-custodial, free-to-use public good model. These milestones mark GasHawk's evolution from proof-of-concept to ecosystem recognition, gradually building long-term sustainable gas optimization infrastructure.
In 2026 GasHawk continued to operate as a transaction layer rather than a single-purpose gas saver: users hand signed transactions to its RPC proxy, which forecasts the low point of base fees inside a chosen window of 30 seconds to 24 hours before broadcasting, saving roughly 30% on average and more than 90% when deadlines are loose. The service is free, works with more than 32 wallets, and can route through Flashbots Protect or MEVBlocker for private order flow.
GasHawk's product mix tilted further toward enterprises during the year. Beyond the browser extension and web app for individuals, the team offers an SDK and REST endpoints so exchanges, custodians, L2s and DeFi protocols can submit transactions in bulk, with pre-submission simulation that flags likely failures, unusual approvals and interactions with blacklisted contracts. With Ethereum base fees persistently low, the absolute savings from delaying inclusion have compressed, shifting value toward failure prevention and MEV protection.
GasHawk's team plans to grow the service into a unified transaction management console with previews, rebates and private order flow, and to replicate the infrastructure across more EVM networks.
