TL;DR

• CrossCurve unifies over $2 billion of Curve TVL into a single cross-chain liquidity layer, delivering 2–5 bps slippage on large trades.
  
• A multi-protocol Consensus Bridge secures transfers via LayerZero, Axelar, Wormhole, Router Protocol and Chainlink CCIP.
  
• A three-layer MetaLayer comprising Transport, Liquidity and Management provides modular, upgradeable infrastructure.
  
• RSquad Blockchain Lab led the TON integration, deploying on-chain modules and relayer agents.

Abstract

CrossCurve addresses fragmented DeFi liquidity by pooling all major Curve stable pools across supported chains into a single, global market. Built in partnership with Curve Finance and powered by Eywa’s multi-protocol Consensus Bridge, it offers users low-slippage cross-chain swaps, one-click token listings, and stacked yields via Curve, Convex, and CrossCurve incentives.

The Problem We’re Solving

Liquid capital is siloed on individual chains, forcing costly incentives and multi-hop transfers that suffer from high slippage, slow finality on optimistic bridges, and bridge-hack risks. Projects compete for TVL, yet users chasing yields face friction and security exposure whenever they move assets between networks.

System Overview

CrossCurve introduces a MetaLayer with three interconnected layers:

1. Transport Layer – Consensus Bridge

• Locks assets on source chain and mints synthetic derivatives on the hub-chain.
  
• Parallel messaging through LayerZero, Axelar, Wormhole and Chainlink CCIP.
  
• Finalizes transfers only on multi-protocol consensus; mismatches trigger automatic refunds.
  

2. Liquidity Layer

• Sonic hub-chain concentrates Curve’s stable liquidity for N²→2N efficiency gains.
  
• On-chain swaps via Curve AMM yield 2–5 bps slippage even on large volumes.
  
• Secure storage in audited Curve pools managing $2 billion+ TVL.
  

3. Management Layer – CrossCurve DAO

• Decentralized governance via EYWA token and ve(3,3) bribery model
  
• Incentives directed to high-value pools, driving activity and deeper liquidity

Key Components

1. Consensus Bridge Contracts on source and hub chains.
   
2. Synthetic Derivatives of Curve LPs (3pool, 3crypto, crvUSD, etc.).
   
3. Universal Tokens (xfrxUSD, xfrxETH, scBTC) for on-chain swaps.
   
4. Curve AMM Pools on Sonic for low-slippage routing.
   
5. CrossCurve DAO managing governance, upgrades and bribery incentives.

Cross-Chain Transfer Flow

1. Lock & Mint user locks asset in Consensus Bridge, mint on Sonic.
   
2. Swap to Universal Token synthetic ↔ universal via Curve pool.
   
3. Swap to Target Synthetic universal ↔ synthetic for destination chain.
   
4. Burn & Unlock synthetic burns on Sonic, original asset unlocks on destination.

Value Proposition

1. Capital Efficiency: 2–5 bps slippage with minimal TVL requirement.
   
   
2. Cost Savings & Rapid Scaling: one hub-chain replaces N² bridges.
   
   
3. Cross-Chain Listings: list any token on all chains against crvUSD, WBTC, WETH, LPs.
   
   
4. Yield Stacking: earn rewards from CrossCurve, Curve, Convex simultaneously.
   
   
5. Enterprise-Grade Security: multi-protocol consensus and audited core.

Governance & Upgrades

All CrossCurve contracts deploy as upgradable proxies. A timelocked N-of-M multisig governed by CrossCurve DAO enables safe patches and feature enhancements without hard forks required.

Ecosystem Impact

CrossCurve unlocks:

• Global Token Launches in one transaction.
  
  
• Cross-Chain DeFi Primitives: lending, staking, vaults with unified liquidity.
  
  
• Seamless LP Migration: chase yields without impermanent loss or manual bridges.

Some Thoughts

CrossCurve transcends “bridging.” It delivers a fully permissionless MetaLayer where liquidity, messaging, and governance converge. With TON support by RSquad Blockchain Lab and Eywa’s Consensus Bridge, CrossCurve sets a new standard for secure, efficient cross-chain DeFi.
