4️⃣Send Router Transaction

Next, use api.buildRouterTransactionRequest to get the transaction request to be sent, which will essentially include the Router contract address (to), transaction data (data), and ETH to be carried in the transaction (value).

const transactionRequest = await api.buildRouterTransactionRequest(routerData);

The structure of the transactionRequest obtained is roughly as follows:

{
  "to": "0xDec80E988F4baF43be69c13711453013c212feA8",
  "data": "0x1c81999100000000000000000000000000000000000000000000000000000000000000600000000000000000000000000000000000000000000000000000000000000a00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000040000000000000000000000000000000000000000000000000000000000000080000000000000000000000000000000000000000000000000000000000000032000000000000000000000000000000000000000000000000000000000000004c00000000000000000000000000000000000000000000000000000000000000780000000000000000000000000000000000022d473030f116ddee9f6b43ac78ba300000000000000000000000000000000000000000000000000000000000000c0000000000000000000000000000000000000000000000000000000000000028000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001842b67b570000000000000000000000000aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa000000000000000000000000a0b86991c6218b36c1d19d4a2e9eb0ce3606eb48000000000000000000000000ffffffffffffffffffffffffffffffffffffffff00000000000000000000000000000000000000000000000000000000645faecd00000000000000000000000000000000000000000000000000000000000000000000000000000000000000009e2a2394c69874545c013492d52d1dc0c607b20800000000000000000000000000000000000000000000000000000000643828d500000000000000000000000000000000000000000000000000000000000001000000000000000000000000000000000000000000000000000000000000000041bb8d0cf3e494c2ed4dc1057ee31c90cab5387b8a606019cc32a6d12f714303df183b1b0cd7a1114bd952a4c533ac18606056dda61f922e030967df0836cf76f91c00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000022d473030f116ddee9f6b43ac78ba300000000000000000000000000000000000000000000000000000000000000c00000000000000000000000000000000000000000000000000000000000000180000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000008436c78516000000000000000000000000aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa0000000000000000000000009e2a2394c69874545c013492d52d1dc0c607b208000000000000000000000000000000000000000000000000000000003b9aca00000000000000000000000000a0b86991c6218b36c1d19d4a2e9eb0ce3606eb48000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000e592427a0aece92de3edee1f18e0157c0586156400000000000000000000000000000000000000000000000000000000000000c000000000000000000000000000000000000000000000000000000000000002400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000144c04b8d59000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000a00000000000000000000000009e2a2394c69874545c013492d52d1dc0c607b20800000000000000000000000000000000000000000000000000000000643828d6000000000000000000000000000000000000000000000000000000003b9aca0000000000000000000000000000000000000000000000000000000000003612330000000000000000000000000000000000000000000000000000000000000042a0b86991c6218b36c1d19d4a2e9eb0ce3606eb480001f4c02aaa39b223fe8d0a0e5c4f27ead9083c756cc20001f42260fac5e5542a773aa44fbcfedf7c193bc2c599000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001000000000000000000000000a0b86991c6218b36c1d19d4a2e9eb0ce3606eb48ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff000000000000000000000000000000000000000000000000000000003b9aca0000000000000000000000000087870bca3f3fd6335c3f4ce8392d69350b4fa4e200000000000000000000000000000000000000000000000000000000000000c000000000000000000000000000000000000000000000000000000000000001800000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000084617ba0370000000000000000000000002260fac5e5542a773aa44fbcfedf7c193bc2c5990000000000000000000000000000000000000000000000000000000000369e050000000000000000000000009e2a2394c69874545c013492d52d1dc0c607b20800000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000010000000000000000000000002260fac5e5542a773aa44fbcfedf7c193bc2c

  "value": "0"
}

For more information on the routerData object and its properties, please refer to the Router Data Documentation.

This is the Router transaction to be sent next. If you're using ethers package, you can refer to the code example to send the transaction:

const signer = provider.getSigner(account);
const tx = await signer.sendTransaction(transactionRequest);

We hope this example helps you get started quickly. If you have any questions or suggestions, please feel free to create an issue on Github, and we will respond as soon as possible.
