Heima and EIP-7702: Omni-Accounts to Simplify Wallets

Heima Network, a Layer-1 full-stack chain abstraction protocol, has announced its Omni-Account module built on EIP-7702, enabling one of the lightest forms of account abstraction available without requiring wallet migrations or bundlers.

The article underscores how developers can upgrade any Externally Owned Account (EOA) on demand, adding smart-contract capabilities natively and eliminating the need for separate wallet deployments.

By leveraging EIP-7702, Heima’s Omni-Account enhances wallet usability and transaction flow, allowing gas abstraction, session keys, and modular security checks to run seamlessly on standard EOAs. Developers gain immediate access to advanced AA features without altering existing infrastructure.

By decoupling smart-contract logic from migration processes, Heima positions its protocol to drive broader AA adoption and smoother Web3 onboarding.

Okto x Etherspot: How Abstraction Changes Everything In Web3

Okto hosted a live video session with Etherspot CEO Michael and Okto’s ecosystem lead Minaal to unpack concepts around account abstraction, chain abstraction, and developer tooling for seamless Web3 experiences.

Minaal explained that Okto began as a retail wallet and evolved into the Okto SDK, which now powers over “50 million plus wallets and about a couple of billion dollars of volume flowing through the platform every month,” enabling one-click DeFi experiences across multiple chains without writing custom integration code.

Michael detailed Etherspot’s origins in smart-contract wallets, emphasising that account abstraction removes repeated signature and gas-token prompts.

The discussion distinguished the two abstractions: account abstraction simplifies on-chain interactions — batching signatures, sponsoring gas, and adding recovery paths — while chain abstraction hides multi-chain complexity, automatically routing liquidity and gas across networks in a single intent-based request.

Both leaders argued that unstoppable growth hinges on iPhone-level usability: invisible, embedded wallets with social logins, session policies, and modular security checks. They foresee AI agents and intent-driven flows building on these foundations to drive the next “iPhone moment” for Web3.

Biconomy Leverages EIP-7702 for Gasless, Multi-Chain MEE Transactions

Biconomy has announced that its Modular Execution Environment (MEE) stack fully embraces EIP-7702, transforming any Externally Owned Account (EOA) into a programmable smart account capable of one-click, gasless, multi-chain workflows.

EIP-7702 “is to EOAs what Ethereum was to Bitcoin,” allowing native accounts to delegate execution to on-chain modules without migrating or deploying new contracts. This protocol-level enhancement lets MEE user operations flow through Biconomy’s Nexus Smart Account (ERC-7579-compliant) implementation, preserving the user’s original address, history, and assets.

In a demo, a user holding only USDC on Arbitrum — with no gas tokens on Arbitrum or Base — supplied WETH to Morpho on Base by signing a single transaction that encoded eight function calls, including bridging via Across, swapping on Uniswap, and supplying to Morpho.

Asynchronous execution support enables flows that wait for oracle updates or schedule repeating calls (e.g., DCA/TWAP), while composability allows developers to template input parameters — MEE dynamically injects actual output values at runtime without manual smart-contract coding.

Developers interface with MEE through AbstractJS, Biconomy’s open-source TypeScript SDK built on Viem. AbstractJS auto-orchestrates dependencies across multiple chains, handles fee sponsorship, and invokes the Modular Execution Environment under the hood — delivering a seamless, Web2-style developer and end-user experience.

By packaging cross-chain bridges, swaps, and protocol interactions into a single signed payload, Biconomy’s MEE removes gas and multi-chain complexity from the user’s workflow and sets a new standard for composable, gasless DeFi experiences.

Stellar Backs HOT Labs with $250K to Integrate Multi-Chain Wallet

HOT Labs has secured a $250,000 grant from the Stellar Development Foundation to integrate Stellar’s blockchain into its HOT Protocol and HOT Wallet products, advancing chain abstraction capabilities.

The grant will cover transaction costs within HOT Wallet, creating a frictionless chain abstraction experience by enabling users to manage Stellar assets without fees.

Founded in 2024, HOT Labs gained rapid adoption with its multi-chain wallet solution, achieving millions of users through features like gasless transactions and decentralised key management.

CTO Andrey Zhevlyakov will lead the three-phase integration: first adding direct Stellar support in HOT Wallet, then extending Stellar compatibility to HOT Protocol and HOT Bridge for seamless cross-chain transfers, and finally linking Stellar’s DeFi ecosystem via HOT Omni Balance.

“Andrey and his team have delivered outstanding results,” said HOT Labs CEO Petr Volnov. “We already see tremendous impact — over 100,000 new USDC holders have joined Stellar since integrating into HOT Wallet. This early success highlights how effective chain abstraction can be in driving blockchain adoption.”

By funding comprehensive Stellar integration, this partnership aims to attract more users and liquidity to Stellar’s ecosystem while showcasing HOT Labs’ chain abstraction innovations, setting a precedent for seamless, cost-efficient multi-chain experiences.
