OpenZeppelin’s Guide on ERC-7786 Cross-Chain Messaging

OpenZeppelin has published a developer guide for ERC-7786, a cross-chain messaging gateway interface designed to streamline interoperability across blockchain networks.

The guide introduces a single gateway interface that abstracts away the complexity of integrating multiple bridges. Developers can implement universal calls for message sending and receiving, regardless of the underlying protocol, reducing vendor lock-in and boilerplate adapter code.

Included examples demonstrate integration with the Axelar Network, showing how to send messages using Axelar’s infrastructure under the ERC-7786 standard. The guide also covers the Multi-Bridge Aggregator pattern, which enables threshold-based confirmations and routing through multiple bridge networks for enhanced reliability.

ERC-7786 defines key functions, such as sendMessage for initiating cross-chain transfers and executeMessage for on-chain delivery, along with a flexible attributes mechanism. Attributes let contracts specify optional parameters (e.g., minimum gas limits) via standardized key-value pairs, ensuring extensibility for diverse bridge features.

By consolidating cross-chain logic into a unified interface and promoting adapter contracts for non-compliant protocols, the ERC-7786 guide aims to foster a new class of composable, cross-chain smart contracts. This standardization paves the way for scalable, protocol-agnostic applications that can seamlessly interoperate across the growing blockchain ecosystem.

Okto Platform Launch for Chain Abstraction

Okto Network has introduced the Okto Platform, a full-stack chain abstraction layer designed to make blockchain interactions as simple as web browsing, handling wallet management, liquidity routing, transaction orchestration, and coordination on a purpose-built chain.

The platform’s wallet component — Decentralized Wallet Networks (DWNs) — provides a single embedded wallet across EVM, Solana, and Aptos, secured by delegated MPC signers run by EigenLayer AVS operators, and enables social-login onboarding without seed phrases.

Its Unified Liquidity Layer (ULL), built on ERC-7683, lets users submit high-level swap intents that are fulfilled by a solver-settler network, delivering seamless any-to-any cross-chain token swaps with optimal routing and pre-loaded liquidity.

The Decentralized Transaction Network (DTN) orchestrates multi-step operations — bundling swaps, bridges, and staking into one-click, intent-driven flows — while supporting gasless execution, MEV protection, and automatic retries for failed transactions.

Underlying these components is the Okto Chain, a ZK-powered L2 on Polygon CDK that records immutable policy and intent data, enforces governance transparently, and anchors security via EigenLayer restaking.

By abstracting gas fees, private keys, and cross-chain complexity behind intuitive interfaces, Okto aims to “bring the world on chain” and drive mainstream adoption by making blockchain invisible to end users and developers alike.

Arcana Launches Arcana Pay App with Unified Chain Abstraction

Arcana Network has introduced Arcana Pay, a demo application showcasing its Chain Abstraction SDK and enabling users to manage and transact assets across multiple EVM chains from a single interface.

The app presents a unified balance view aggregating USDT, USDC, and ETH, so users can see all their assets at a glance without switching wallets or chains.

With one-click send or bridge functionality, Arcana Pay lets users transfer tokens across EVM networks seamlessly — “No bridging or swapping” is required, as the SDK handles all cross-chain logic under the hood.

Users connect their existing wallets, sign a single transaction, and the Chain Abstraction SDK orchestrates everything: routing, fee management in native tokens, and execution across source and destination chains.

By demonstrating its SDK’s ability to abstract away gas fees, wallet setups, and manual token routing, Arcana Pay underscores how chain abstraction can drive mainstream Web3 adoption by making cross-chain asset management as intuitive as traditional payment apps.

Abstract’s Onchain UX with Cookie Clicker Demo

Cygaar, the software engineer of Abstract, has announced that real-time transactions are coming to the AbstractChain network, showcasing a cookie-clicker application where every click is executed as an immediate on-chain transaction.

The live demo illustrates how Web2-style user experiences can be secured by blockchain under the hood, with near-zero delay between interaction and transaction confirmation.

To eliminate wallet popups, the demo leverages Account-Gateway-Wrappers (AGW) and session keys, allowing users to interact seamlessly without signing prompts for each action.

Cygaar explained that a specialized RPC endpoint — set to go live on mainnet soon — pre-fetches transaction statuses, enabling the application to display confirmations in real time.

By combining session-based authentication with advanced gateway modules, AbstractChain’s architecture promises to make every decentralized app feel as responsive and intuitive as traditional web applications.

Is Chain Abstraction Dead?

Xion CEO Anthony Anzalone has proclaimed that “chain abstraction is dead,” arguing in a recent podcast that blockchain must deliver clear user value rather than just hiding gas fees and private keys. He insisted that abstractions only matter when they solve real problems for non-technical users.

Anzalone highlighted Xion’s partnerships with Uber, Amazon, and BMW as examples of practical, enterprise-grade chain abstraction in action. He noted that these integrations leverage Xion’s Title II EU-compliant Layer-1 blockchain to enable seamless, decentralized services without exposing users to on-chain complexity.

Since its mainnet launch, Xion has scaled from 60,000 to 100,000 daily active users and secured a $12 million Thrive program, demonstrating that consumer adoption hinges on compelling use cases rather than technical novelty. The network now supports over 250,000 weekly and one million monthly active users across global markets.

Looking ahead, he envisions a future where blockchain “fades into the background” and users interact via high-level intent. By combining smart accounts, AI agents, and intent-driven flows, Xion aims to make decentralized applications feel as intuitive as Web 2 services, marking the true evolution beyond mere chain abstraction.
