Summary
We propose partnering with Omnilane to privately bridge tokens to and from any chain that supports ECDSA signature verification over the secp256k1 curve.
Omnilane is a next-generation cross-chain liquidity protocol that enables fast, secure, and cost-efficient token bridging and swaps across any blockchain—without relying on oracles, validators or sidechains.
Powered by its unique Cumulative State Consensus algorithm and NEAR chain signatures, Omnilane delivers zero-slippage, MEV-resistant swaps with exact pricing and near-instant settlement. Its peer-to-peer limit order model boosts capital efficiency, while seamless integration allows wallets, DEXes, and dApps to easily offer cross-chain functionality.
The Cumulative State Consensus is Omnilane’s proprietary algorithm for executing secure, atomic swaps across multiple blockchains. Each party involved acts as its own verifier, thereby eliminating the need for third-party intermediaries. This decentralized verification model ensures that any malicious behavior only impacts the originator, thereby preserving the overall integrity of the transaction.
With ultra-low fees, composability, and a strong revenue-sharing model, Omnilane sets a new standard for scalable, trustless, and user-friendly cross-chain infrastructure.
For this MVP, Arbitrum’s testnet will be used.
Start and End Date
We anticipate to start working on 1 April 2025 and deploy a functional version on the Aztec Testnet by end of May 2025.
About You
Rather Labs has extensive blockchain experience, delivering innovative solutions across diverse ecosystems. Our portfolio includes Hatom, the leading lending platform on MultiversX; PyTON, an EVM-compatible Layer 2 for TON; Soul Labs, a cross-chain lending platform leveraging LayerZero; and the development of the NRC-721 NFT standard for Nervos. These projects involved innovative low-level development, such as zero-knowledge libraries for TON and optimized data structures for MultiversX.
Additional details and case studies can be found on our company’s deck:
Furthermore, we have a strong strategic partnership with Omnilane Labs that facilitates working in close collaboration with its developers.
A short bio of the team involved in this proposal follows:
-
Federico Caccia is a tech leader with 10+ years of experience in blockchain and AI, backed by a strong foundation in Nuclear Engineering. As CEO of Rather Labs, Rather Ventures, and Omnilane, he has developed DeFi protocols and cross-chain solutions, blending tech skills with sharp business acumen.
-
Franco Scucchiero is a blockchain entrepreneur with 7+ years as a developer and 5 years in sustainable finance, gaming, and DeFi. As CTO of Hatom Labs and Rather Labs and 6 times cofounder, he merges tech expertise with entrepreneurial vision, driving sustainable and impactful blockchain innovation.
-
Ignacio Fabre holds a PhD in Theoretical Physics with 15+ academic publications. He transitioned to Data Science, taught Machine Learning at an Argentine National University, and now leads R&D as Head of Innovation at Rather Labs and Head of Engineering at Membrane Labs. Co-founder of TranscribeMe.
-
Juan Beliera holds a Master’s degree in Mathematical Engineering and 9 years of experience in software development within the nuclear industry. He has specialized in the design and implementation of software for nuclear reactor simulations, working primarily with Ada, C++, Fortran, Julia, and Python. In late 2024, he transitioned to the fields of artificial intelligence and blockchain development, joining the innovation team at Rather Labs.
The following flows will be implemented by the end of the MVP.
Transfer from L2 to private Aztec address
Figure I: A high level overview of the components and the transfer to Aztec flow
- The user generates an order for a transaction with the hash of an address and a secret as a receiver
- Tokens are locked in the bridge’s vault
- A solver listens to a new order and settles the order by signing a transaction transferring tokens from his vault on the destination chain to a claimable vault.
- A Relayer transfers the signed transaction to the destination chain, collecting the associated fees from the solver’s vault
- The user can claim the assets on the destination chain without revealing his identity by revealing the address and secret.
- Alternatively, the user can cancel the order (A# actions on the diagram) before a solver settles it.
Private transfer from Aztec to L2
Figure II: A high level overview of the components and the transfer from Aztec flow
- The user privately generates an order for a transaction with destination address
- Tokens are locked in the bridge’s vault
- A solver listens to a new order and settles the order by signing a transaction transferring tokens from his vault on the destination address.
- A Relayer transfers the signed transaction to the destination chain, collecting the associated fees from the solver’s vault
- Alternatively, the user can cancel the order (A# actions on the diagram) before a solver settles it, to do this he must show the secret associated with the order.
Public transactions will also be allowed and they can trivially be derived from the “private transfer from Aztec to L2” flow.
In its current implementation, Omnilane sponsors all fees; this same approach will be used for contracts to be deployed on-chain.

Grant Amount Requested
50.000 USD
Grant Budget Rationale
The requested budget will be allocated for the following resources:
- Team composition:
- 1 Blockchain Engineer to act as a Technical Lead
- 1 Fullstack Engineer
- Project Management and QA support from RatherLabs
- Operational costs for development and deployment.
- Marketing activities (workshop and post) to promote the app and the partnership with Aztec
Any extra budget will serve as a contingency for any needed extra development (e.g. potentially to expand over Omnilane’s crosschain functionalities to fully support this MVP) or for further marketing activities.
