​
Available Values and Data Sources

This section explains how to obtain the dynamic values required for certain API parameters and lists fixed possible values for others.

​
Chain IDs (chainId)

Chain IDs represent different blockchains supported by Hyperswap.
  • Source: These can be obtained by calling the /api/v1/assets endpoint. Each StandardizedAsset object in the response includes a chainId field.
  • Format: Chain IDs can be numerical (for EVM chains) or string identifiers (for non-EVM chains).
  • Examples:
    • EVM Chains (Numerical): 1 (Ethereum), 56 (BNB Chain), 137 (Polygon), 42161 (Arbitrum One), 10 (Optimism), 8453 (Base), 43114 (Avalanche), 25 (Cronos), 324 (ZkSync Era), 59144 (Linea).
    • Non-EVM Chains (String Identifiers/Internal Mappings): '1151111081099710' (Solana), '20000000000001' (Bitcoin), '9270000000000000' (Sui), 'TRON' (Tron), 'TON' (TON), 'APTOS' (Aptos), 'ALGORAND' (Algorand), 'BITTENSOR' (Bittensor), 'CARDANO' (Cardano), 'CELESTIA' (Celestia), 'COSMOS' (Cosmos), 'DASH' (Dash), 'DOGE' (Dogecoin), 'HEDERA' (Hedera), 'ICP' (Internet Computer), 'LITECOIN' (Litecoin), 'MANTLE' (Mantle), 'POLKADOT' (Polkadot), 'RIPPLE' (Ripple), 'RONIN' (Ronin), 'STACKS' (Stacks), 'STELLAR' (Stellar), 'XEC' (eCash), 'BCH' (Bitcoin Cash), 'LIQUID' (Liquid), 'HYPEREVM' (Hyperevm), 'SONIC' (Sonic), 'BLAST' (Blast), 'SCROLL' (Scroll), 'FETCH' (Fetch).
  • Note: The chainName and chainLogoUrl fields in the asset response can help identify the human-readable name and logo for each chain. For the most current list of supported chains, always query the /api/v1/assets endpoint.

​
Token Addresses (fromToken, toToken)

Token addresses identify specific crypto assets on a given blockchain.
  • Source: These are obtained by calling the /api/v1/assets endpoint. Each StandardizedAsset object includes an address field, which represents the token’s contract address on its respective chainId.
  • Native Tokens: For native blockchain tokens (e.g., ETH on Ethereum, BTC on Bitcoin, SOL on Solana, SUI on Sui), specific normalized addresses are used:
    • EVM Native: 0x0000000000000000000000000000000000000000
    • Bitcoin: 'bitcoin'
    • Solana: '11111111111111111111111111111111'
    • Sui: '0x2::sui::SUI'
  • Note: The symbol and name fields in the asset response provide human-readable identifiers for the tokens.

​
Preference (preference)

This parameter allows specifying the desired optimization for a quote.
  • Possible Values:
    • 'fastest': Prioritizes quotes with the quickest estimated completion time.
    • 'lowest_cost': Prioritizes quotes with the lowest estimated fees.

​
Transaction Statuses (status)

These are the possible states for a swap transaction.
  • Possible Values:
    • PENDING: The transaction has been initiated but is awaiting further action (e.g., user deposit for hyperswapshift, user signature for hyperswap).
    • IN_PROGRESS: The swap is actively being processed by the liquidity provider.
    • COMPLETED: The swap has successfully finished, and funds have been settled.
    • FAILED: The swap encountered an unrecoverable error.
    • REFUNDED: The swap failed, and funds have been returned to the refund address.
