At ZeroSwapLabs we have been consistently building with the aim to increase crypto adoption globally by addressing the issues of higher gas fee & transaction fee for users while making transactions. We have successfully launched our gasless multi chain & cross chain ecosystem and it’s now time to level up!

We have now deployed contracts on zkEVM and zkSync testnets with the goal of attaining more secure and scalable transactions. Our zkEVM & zkSync testnets will be supported with a dApp to enable swapping of tokens.

Currently at ZeroSwapLabs we have deployed our own swapping contract which holds the liquidity of tokens and acts as an AMM. These swaps happen according to the quote provided for a specific token pair which will be fetched from 0x API.

About Tokens on zk testnet:

Here’s a list of the tokens that are currently available on on both zkEVM and zkSync testnet:

ZK-EVM TESTNET

$USDT, $USDC, $WBTC $DAI $ZEE $WETH $SHIB

ZK-SYNC TESTNET

$USDT, $USDC, $WBTC, $DAI, $ZEE, $WETH, $SHIB

Please note that ONLY the above-mentioned tokens are available for making swaps on the ZeroSwap zkDEX

About Swap Contract:

This is the contract that will facilitate the precise exchange of tokens. Herein, the sell token shall be received and the buy token shall be transferred to the intended recipient with exactitude and accuracy.

The contracts are:

zk-EVM Testnet: Swap Contract: 0xF05B2B56de582C583Ead24279722952A3Bf571d7

zk-Sync Testnet: Swap Contract: 0xC7Cc5c6842529514C52c7Fc669C09Aaf98194938

About Faucet:

The faucet is a web-based service that provides test tokens to users of the ZeroSwapDEX zk-testnets. While these tokens have no real-world value, they will enable you to experiment with ZeroSwapDEX zk-testnet features.

You can request testnet tokens from this contract once in 24hrs. USDT and WETH will be sent to you. Once you receive the tokens, you can swap them for any other token mentioned above from the dApp.
