Get all supported blockchains, tokens and swappers meta data
Last updated
This service gathers all the essential data needed for a swap's UI, including list of all blockchains, tokens and protocols (DEXes & Bridges) metadata.
Why is it recommended to obtain the list of supported blockchains from Rango API?
For working with other API methods like quote or swap, you need to have identifier (name) of each blockchain. You could hard code blockchain names if you want to have limited chains support or get them dynamically via the API. (You could store a map of each blockchain chainId to Rango name if required.)
Because of different reasons like blockchains maintenance, Rango maintenance, DeFi protocols hacks, and etc, a blockchain could be disabled in Rango. You could check which blockchains are enabled now using enabled flag for each blockchain in meta response.
When is it required to obtain the list of supported tokens from Rango API?
Even if dApp has its own list of tokens and blockchains, it's still useful to get list of supported tokens by Rango:
To avoid unnecessary API calls when a token is not supported by Rango: For EVM and Solana blockchains, Rango supports custom tokens, so it's fine to pass tokens outside the list of Rango token list. However, for the other blockchains, we currently only support tokens that are on our existing token list (meta response).
For Cosmos-based blockchains, the token's symbol is required to retrieve a quote for each token. Thi will be addressed in a future update.
blockchains String
Description: Pass comma separated list of blockchains if you want to filter meta blockchains to some specific ones.
Example: POLYGON,ETH
blockchainsExclude Boolean
Description: A value indicating whether the specified blockchains should be excluded or included in the response.
Example: true
swappers String
Description: Pass comma separated list of swappers if you want to filter meta swappers to some specific ones.
Example: Across,OneInchEth
swappersExclude Boolean
Description: A boolean value indicating whether the specified swappers should be excluded or included in the response.
Example: false
swappersGroups String
Description: Pass comma separated list of swapper groups if you want to filter meta swapper groups to some specific ones.
Example: Across,1Inch
swappersGroupsExclude Boolean
Description: A boolean value indicating whether the specified swapper groups should be excluded or included in the response.
Example: false
transactionTypes String
Description: Pass comma separated list of transaction types if you want to filter blockchains types to some specific ones.
Example: EVM,COSMOS
transactionTypesExclude Boolean
Description: A boolean value indicating whether the specified transaction types should be excluded or included in the response.
Example: false
excludeSecondaries Boolean
Description: It indicates whether secondary tokens should be excluded from the response. By secondary tokens, we mean tokens that are imported from our secondary tokens lists.
Example: false
excludeNonPopulars Boolean
Description: It indicates whether non-popular tokens should be excluded from the response. By popular tokens, we mean native token and stable coins of each blockchain.
Example: false
enableCentralizedSwappers Boolean
Description: Set this flag to true if you want to enable routing through the centralized solutions and obtain the associated metadata, including related swappers and tokens. The default value for this argument is false.
Example: true
blockchains
Description: List of all supported blockchains
tokens
List of all tokens
swappers
List of all supported protocols (DEXes & Bridges)
If you only want to load a specific part of metadata rather than full metadata, i.e. only blockchains data, tokens list or supported protocols, you can use the following methods/endpoints:
