Ready to make cross-chain swap messages with ease? 🤝

XCM Router can perform cross-chain transactions between Polkadot/Kusama Parachains and Relay chains as well. It works across 8 open-source Parachain DEXes.

These are:

• Acala / 36 Pools available
• Basilisk / 15 Pools available
• BifrostKusama / 66 Pools available / Requires native token for swaps
• BifrostPolkadot / 45 Pools available / Requires native token for swaps
• HydraDX / 210 Pools available
• Interlay / 10 Pools available / Requires native token for swaps
• Karura / 136 Pools available
• Kintsugi / 6 Pools available / Requires native token for swaps

Totalling to 524 pools available for cross-chain swap transactions.

NOTE: Some exchanges require native tokens to proceed with swaps.

Automatic exchange selection

If you wish to have an exchange chain selection based on the best price outcome, you can opt for the automatic exchange selection method. This method can be selected by not using .exchange() parameter in the call. The router will then automatically select the best exchange chain for you based on the best price outcome.

Builder pattern

await RouterBuilder
        .from('Polkadot')   //Origin Parachain/Relay chain - OPTIONAL PARAMETER
        .to('Astar')    //Destination Parachain/Relay chain - OPTIONAL PARAMETER
        .currencyFrom({symbol: 'DOT'})    // Currency to send - {id: currencyID, amount: amount} | {symbol: currencySymbol, amount: amount} | {symbol: Native('currencySymbol'), amount: amount} | {symbol: Foreign('currencySymbol'), amount: amount} | {symbol: ForeignAbstract('currencySymbol'), amount: amount} | {multilocation: AssetMultilocationString, amount: amount | AssetMultilocationJson, amount: amount} 
        .currencyTo({symbol: 'ASTR'})    // Currency to receive - {id: currencyID, amount: amount} | {symbol: currencySymbol, amount: amount} | {symbol: Native('currencySymbol'), amount: amount} | {symbol: Foreign('currencySymbol'), amount: amount} | {symbol: ForeignAbstract('currencySymbol'), amount: amount} | {multilocation: AssetMultilocationString, amount: amount | AssetMultilocationJson, amount: amount}
        .amount('1000000')  // Amount to send
        .slippagePct('1')   // Max slipppage percentage
        .senderAddress(selectedAccount.address)   //Injector address
        .recipientAddress(recipientAddress) //Recipient address
        .signer(injector.signer)    //Signer
        //.evmSenderAddress(evmInjector address)   //Optional parameters when origin node is EVM based (Required with evmSigner)
        //.evmSigner(EVM signer)                     //Optional parameters when origin node is EVM based (Required with evmInjectorAddress)

        .onStatusChange((status: TTxProgressInfo) => {  //This is how we subscribe to calls that need signing
          console.log(status.hashes);   //Transaction hashes
          console.log(status.status);   //Transaction statuses
          console.log(status.type);    //Transaction types
        })
        .buildAndSend()

AccountId32 and AccountKey20 addresses can be directly copied from PolkadotJS as our SDK has a handler to convert it into the desired hex string automatically.

Eg. use standard public key 141NGS2jjZca5Ss2Nysth2stJ6rimcnufCNHnh5ExSsftn7U Instead of 0x84fc49ce30071ea611731838cc7736113c1ec68fbc47119be8a0805066df9b2b

Manual exchange selection

If you wish to select your exchange chain manually you can do that by providing additional parameter .exchange() in the call. The router will then use the exchange chain of your choice.

Builder pattern

await RouterBuilder
        .from('Polkadot')   //Origin Parachain/Relay chain - OPTIONAL PARAMETER
        .exchange('HydraDxDex')    //Exchange Parachain
        .to('Astar')    //Destination Parachain/Relay chain - OPTIONAL PARAMETER
        .currencyFrom({symbol: 'DOT'})    // Currency to send - {id: currencyID, amount: amount} | {symbol: currencySymbol, amount: amount} | {symbol: Native('currencySymbol'), amount: amount} | {symbol: Foreign('currencySymbol'), amount: amount} | {symbol: ForeignAbstract('currencySymbol'), amount: amount} | {multilocation: AssetMultilocationString, amount: amount | AssetMultilocationJson, amount: amount} 
        .currencyTo({symbol: 'ASTR'})    // Currency to receive - {id: currencyID, amount: amount} | {symbol: currencySymbol, amount: amount} | {symbol: Native('currencySymbol'), amount: amount} | {symbol: Foreign('currencySymbol'), amount: amount} | {symbol: ForeignAbstract('currencySymbol'), amount: amount} | {multilocation: AssetMultilocationString, amount: amount | AssetMultilocationJson, amount: amount}
        .amount('1000000')  // Amount to send
        .slippagePct('1')   // Max slipppage percentage
        .senderAddress(selectedAccount.address)   //Injector address
        .recipientAddress(recipientAddress) //Recipient address
        .signer(injector.signer)    //Signer
        //.evmSenderAddress(evmInjector address)   //Optional parameters when origin node is EVM based (Required with evmSigner)
        //.evmSigner(EVM signer)                     //Optional parameters when origin node is EVM based (Required with evmInjectorAddress)

        .onStatusChange((status: TTxProgressInfo) => {  //This is how we subscribe to calls that need signing
          console.log(status.hashes);   //Transaction hashes
          console.log(status.status);   //Transaction statuses
          console.log(status.type);    //Transaction types
        })
        .buildAndSend()
