Two developers, Friederike Ernst and Eduardo Antuña Díez, took the Lotus Stage 1 at Devcon in Mumbai, India, to demonstrate three synchronous integrations between Ethereum’s base layer (L1) and rollup networks (L2). Under the Ethereum Economic Zone (EEZ) initiative, the technical demonstration showcased two-way cross-layer interactions completed in a single continuous process.
The tests in Mumbai build on an achievement in October 2026, when the EEZ completed its first atomic transaction of 0.001 ETH between Ethereum and a rollup. What sets this demonstration apart is a direct integration that eliminates the need for separate bridges as well as waiting times for users.
How CoW Swap Orders Run Without a Bridge
The first demonstration featured the CoW Swap protocol on Rollup X. In this scenario, users signed orders that were executed directly using Ethereum mainnet liquidity via CoW Swap solvers.
Order execution was settled in a single atomic transaction. Users did not need to transfer assets via a separate bridge transaction, faced no waiting times, and were not required to provide additional signatures.
This mechanism allows new rollup networks to tap directly into Ethereum’s primary liquidity. Protocols on L2 are no longer confined to shallow local pools, avoiding high slippage or wide execution price disparities.
Synchronizing Safe Wallet Permissions Across Networks
The second test utilized Safe multisig wallet infrastructure. In front of Devcon attendees, the EEZ team demonstrated updates to the authorized signers list and treasury management processed simultaneously across layer-1 and layer-2.
Safe configuration changes on the Ethereum mainnet can be verified instantly from the connected rollup in a single transaction. This real-time validation prevents account permission inconsistencies for decentralized autonomous organizations (DAOs) when managing treasuries across multiple chains.
Testing Falcon Cryptographic Validation on Rollups
In the third demonstration, the EEZ team tested the verification of Falcon post-quantum cryptographic signatures on Rollup X. A smart contract on Ethereum mainnet called a contract on the rollup to validate the signature before authorizing the fund transfer in a single atomic transaction.
The Falcon algorithm is specifically designed to secure network transactions against potential future quantum computer attacks. The test on Lotus Stage 1 proved that future-proof computational protection can be integrated into cross-chain execution without splitting the process into separate transactions.
For DAO treasury managers and layer-2 users, this series of innovations delivers clear technical certainty: order execution is no longer held back by bridge queues, while account governance stays synchronized with mainnet without requiring duplicate authorizations. Reported by crypto.news.
