Ether.fi pledges $3 billion worth of ETH to ETHGas as validator liquidity over three years
According to The Block, Ethereum liquid re-staking protocol Ether.fi announced it will supply a total of $3 billion worth of Ethereum as “validator liquidity” to the ETHGas market over the next three years, funded by its managed 2.8 million staked ETH. ETHGas is an Ethereum blockspace futures market that enables pre-purchasing of blockspace to guarantee transaction execution. This initiative aims to enhance validator returns by selling blockspace commitments, helping validators capture more maximum extractable value (MEV) and achieve higher, more predictable yields. ETHGas has secured institutional investment from firms including Polychain Capital and has launched its governance token GWEI, currently valued at approximately $120 million. Ether.fi’s native token ETHFI has a market cap of roughly $332 million. This move will provide developers and enterprises with more predictable transaction costs and execution times, advancing Ethereum’s development as a global institutional capital settlement layer.

Nava Secures $8.3M Seed Round Led by Polychain and Archetype
According to Fortune, blockchain startup Nava has announced the completion of an $8.3 million seed funding round, co-led by Polychain and Archetype, aiming to prevent anomalous operations by AI financial agents through a custody and verification framework. Nava’s solution locks funds via custodial services; once an AI agent proposes a transaction, an on-chain verification mechanism assesses whether the transaction aligns with the user’s intent—only compliant transactions are executed, while non-compliant ones leave funds in custody. All verification decisions are publicly recorded on the blockchain for reference by other AIs. Nava currently operates as a Layer 3 blockchain on Arbitrum and plans to deploy a parallel chain on Tempo; it will also issue a native stablecoin in the future to support protocol operations. Nava’s infrastructure serves both individual users and institutions, enhancing asset security and transaction transparency.
