Third-Party Integrations


What is Transak?

Transak is a developer integration toolkit that enables onboarding of users to buy/sell crypto in any blockchain app, website or web plugin. Transak helps onboard mainstream users into dApp, protocol, game or wallet app.

Transak on

Transak is integrated on KyberSwap through a browser integration that will redirect users to Transak to access their fiat on ramp services.

*All of the KYC, regulation & compliance, fiat payment methods, and crypto coverage are solely handled by Transak.

Clicking "Buy Crypto" will bring you to a third party website, owned and operated by an independent party over which KyberSwap has no control ("Third Party Website").

Axelar x Squid

What is Axelar?

Axelar delivers secure cross-chain communication for Web3, enabling you to build Interchain dApps that grow beyond a single chain. Secure means Axelar is built on proof-of-stake, the battle-tested approach used by Ethereum, Polygon, Cosmos, and more. Cross-chain communication means you can build a complete experience for your users that lets them interact with any asset, any application, on any chain with one click.

What is axlUSDC?

axlUSDC is a wrapped, multi-chain representation of USDC, a dollar stablecoin. For each unit of axlUSDC, there is a unit of USDC locked in an Axelar Gateway on Ethereum. axlUSDC is secured by a dynamic validator set running delegated Proof-of-Stake, which holds key shares in the Axelar Gateways via multi-party cryptography.

What is Squid?

Squid is the cross-chain swap and liquidity routing protocol on Axelar Network.

Squid utilises existing DEXs to swap and send any native token between chains. This can be done via their SDK, Front End or Contracts directly.

Swaps are composable with Axelar's generalised message passing, so Squid can enable one-click transactions between any application and any user, using any asset.

Buy NFTs from any marketplace, use multi-chain DeFi, play a game on another chain, all without signing multiple transactions or downloading multiple wallets.

Why Axelar x Squid?

By routing transactions through axlUSDC/USDC stable swap pools as well as USDC/native token pools, Squid supports swapping of any token combination across supported chains. Built on top of Axelar, Squid leverages Axelar's general cross-chain messaging abilities as well as its axlUSDC ecosystem to enable secure cross-chain token swaps.

Squid is integrated on KyberSwap through API front end functionality to provide users with an option to conveniently swap tokens across the following supported chains:

  • Ethereum (ChainID: 1)

  • BSC (ChainID: 56)

  • Arbitrum (ChainID: 42161)

  • Polygon (ChainID: 137)

  • Fantom (ChainID: 250)

PayMaster x HoldStation

What is PayMaster?

Paymasters are smart contracts that able to pay gas fees for users. A Paymaster conversely, can sponsor transactions for users, enabling users to pay transaction fees in ERC20 tokens. This innovative approach to account management significantly enhances user experience, security, and flexibility, paving the way for broader adoption of blockchain technology.

The concept of paymasters, designed to enhance flexibility, user experience and transaction sponsorship in ERC-20 tokens, respectively. Despite some similarities with Ethereum's EIP 4337, key differences shape zkSync's unique account management approach.

To interact with a paymaster, EOA users sign their EIP-712 transaction.

PayMaster powered by HoldStation on

PayMaster is integrated on KyberSwap's Aggregator that will allow the users to access its account abstraction capabilities.

This development empowers KyberSwap users by offering the flexibility to pay gas fees using various tokens such as $USDC, $USDT, (wBTC TBA) and $HOLD

One of the standout features of this launch is that users are no longer required to maintain ETH in their wallets. This enhancement simplifies the user experience and adds a new layer of convenience to the KyberSwap platform.

Disclaimer: The PayMaster module & contracts integrated on KyberSwap was developed and is operated by HoldStation. KyberSwap doesn't hold any responsibility over the feature.


What is Flashbots?

Flashbots Protect RPC allows regular users to easily submit their transactions to the Flashbots Auction by using a custom RPC endpoint in their wallet. Everything should be the same for users, except transactions are sent to the Flashbots builder instead of the public mempool.

Key benefits to using the Flashbots RPC endpoint:

  • Frontrunning protection: your transaction will not be seen by hungry sandwich bots in the public mempool.

  • No failed transactions: your transaction will only be included if it doesn't include any reverts, so you don't pay for failed transactions.

    Note: your transaction could be uncled, emitted to the mempool, and then included on-chain.

Privacy notice: Flashbots Protect RPC does not track any kind of user information (i.e. IP, location, etc.). No user information is ever stored or even logged.

KyberSwap provides its user the option to conveniently connect to the Flashbots RPC when trading on the Ethereum mainnet.


What is MEVBlocker?

MEV Blocker facilitates an auction between a network of “searchers” who are given the opportunity to backrun your transactions. In return, they protect you from frontrunning and sandwich attacks - the nasty types of MEV that exploit Ethereum users every day.
