OverHerd Pays 500K+ Users Across Multiple Chains Using Biconomy's Invisible Web3 Infrastructure

A new cross-chain workflow enables users to execute complex DeFi operations across two blockchains with a single signature. **How it works:** - User signs once to authorize the entire process - Origin chain batch unwinds lending position and creates an intent - Solver bridges funds between chains - Destination chain batch waits for funds, verifies amount, and supplies to yield farm **Technical stack:** - **ERC-7964** handles signature authorization - **ERC-8211** encodes chain-specific steps with live values and conditions - **Open Intents Framework** manages cross-chain liquidity movement The system eliminates manual intervention between steps, automating what previously required multiple transactions and constant monitoring. Users initiate complex multi-chain strategies without touching anything after the initial signature.

A new approach to cross-chain transactions eliminates hardcoded values in favor of **dynamic resolution**. Instead of specifying exact amounts like "supply 487 USDC," each step now resolves values in real-time based on what actually arrives. Key features: - Steps carry their own conditions and can wait for prerequisites - Destination batches gate on fund arrival confirmation - Relayers only submit once conditions are met - **No glue contract needed** - ERC-8211 reads state directly, not the bridge - Compatible with Open Intents Framework or other underlying layers The system stacks into a single flow: one ERC-7964 signature authorizes the plan, ERC-8211 encodes each chain's steps with live values and conditions, and the Open Intents Framework handles liquidity movement while destination batches wait before continuing.

The **Open Intents Framework** addresses fragmented cross-chain liquidity through an open-source, solver-agnostic standard. **How it works:** - Users sign an intent and lock funds on the origin chain - Competing EVM solvers front the funds on the destination chain - A proof releases locked funds to reimburse the solver The framework enables complex cross-chain operations—like unwinding a lending position, bridging funds, and supplying to a yield farm—through a single intent.

**ERC-8211** addresses a critical gap in cross-chain operations: the inability to write scripts when you don't know exact amounts until execution. **The Problem:** - Bridge transactions create uncertainty - you can't predict final amounts before execution - Supply steps can't fire until funds actually arrive - Traditional scripts require hardcoded values **The Solution:** ERC-8211 enables dynamic value resolution: - Steps resolve values live ("supply whatever just arrived" vs "supply 487 USDC") - Built-in conditions allow steps to wait for confirmation - Destination batches gate on "have funds landed?" - Relayers submit only when conditions are met - No glue contracts needed - reads state directly, not the bridge - Works with OIF or any underlying layer Learn more at [erc8211.com](https://www.erc8211.com)

**ERC-7964** introduces cross-chain signature capability for EVM transactions. Traditional EVM signatures authorize execution on only one chain at a time. This creates friction when actions need to span multiple chains. The new standard allows developers to: - Encode multiple calls across different chains into a single EIP-712 object - Sign the entire array once - Execute the complete cross-chain workflow with that one signature This removes the need for separate signatures on each chain, streamlining multi-chain operations.
