🔄ChainSwap

The fastest way to purchase tokens on Arbitrum using mainnet ETH.

Introduction

With the use of ChainSwap, you could buy a token on Arbitrum in a matter of seconds by using your ETH on the Ethereum mainnet. Thus creating the quickest and most convenient way for users with no funds on Arbitrum to purchase there.

This is achieved through two smart contracts, one on Ethereum and one on Arbitrum, facilitated by a relayer that processes swap requests.

It also refuses any bridging requests from OFAC-sanctioned addresses.

Tokenomics

ChainSwap imposes a total swap fee of 2.5%, distributed as follows:

• 1.0% rewards liquidity providers

• 1.0% is the Development fee

• 0.5% referral fee

• 0.001 to 0.002 ETH transaction cost to cover relay fees

Operations

Users deposit their ETH in the Ethereum contract during a swap request, and the corresponding amount is used from the Arbitrum contract to fulfill their request. Liquidity providers earn 1.0% of the total swap volume, paid automatically in ETH on Arbitrum.

Deposits are fixed at 1 ETH with a minimum wait period of 1 day to prevent withdrawal exploits. There are no deposit/withdrawal fees. Withdrawals are possible at any time given sufficient ETH in the Arbitrum contract.

Efficiency Measures

A feedback mechanism ensures sufficient ETH in both contracts. If the Arbitrum contract is low on ETH, it triggers a transaction to transfer all ETH from the Ethereum contract. The system is gas optimized, making it cheaper than trading on Uniswap and more than 10 times cheaper than our main competitor - Sushi xSWAP. Note: Check Flowchart 4

Referral System

An adjustable referral fee ranges from 0.5% to 1.5%, allowing partner protocols or individuals to customize their earnings. The cost to the user remains unaffected, as any increase in the referral fee is deducted from the protocol fee & LP rewards.

Swap Algorithm

ChainSwap's contract determines the best swap path, searching for TOKEN/WETH and TOKEN/USDC pairs across four DEXes on Arbitrum: UniV3, SushiSwap, Camelot, and AlienSwap. A fast relay time of 20-40 seconds ensures efficient delivery of swap requests.

Making a swap request on ETH contract costs about 34k gas. This is 2x, 3x cheaper than Uniswap. Sending ETH+LP Rewards back to Arbitrum — 120k gas.
