API v6.2
Introduction to ParaSwap API v6.2
ParaSwap v6.2 has been released! See what's new here: https://twitter.com/paraswap/status/1803435422011498551
To switch to v6.2, you only need to pass &version=6.2
to /prices
& you're good to go!
ParaSwap V6.2's main goal is to provide the best possible gas-optimized protocol for order routing. The V6.2 comes with significant improvements in terms of smart-contract architecture that achieve both best-in-class gas efficiency and scalability through modularity.
To use V6.2, you need to pass &version=6.2
query param when calling /prices
. The process for swapping remains the same:
Call
GET /prices
to retrieve an optimal price for a given pair & amount.Call
POST /transactions
for retrieving the Transaction Object that includes the calldataAlternatively, you can use GET
/swap
to retrieve both the price config & Transaction Object.
You can also use the JavaScript/TypeScript SDK for easier integrations: https://github.com/paraswap/paraswap-sdk
No longer need to approve a different smart contract for ERC20 tokens. Augustus V6.2 is the only contract you need to interact with. More details here.
More control over partner fees: should you choose to take a surplus fee, you can cap it to 1% of the trade volume as protection for your users if it applies to your specific case. You can also sent partner fees directly to the user. Take a look at new params (
isCapSurplus
,isSurplusToUser
,isDirectFeeTransfer
) params in /transactions section.Flat fees are capped at 2% as a security protection for users.
excludeDirectContractMethods
is no longer supported in /prices, it's replaced byexcludeContractMethodsWithoutFeeModel
if you want to make sure all swaps can monetize. (ie. swaps fees don't work whenswapOnUniswap
,swapOnUniswapFork
,swapOnZeroXv2
, andswapOnZeroXv4
etc. contract methods are used.)
