Deposit into Aave from Solana

Pre-release — The Intents Connect API is currently in development. If you're interested in early access, get in touch with the team.

Below is an example flow depositing into Aave using a Solana wallet using the Intents Connect API.

You'll need to reference supported assets by their IDs, then run a dry execution to get the estimated output amount, and estimate costs for the destination chain action, signing the intent (deposit to Aave), and the transfer transaction to move SOL from the Solana wallet. As a result, you'll have deposited Aave into an intermediary account associated with your Solana wallet.

Make sure to understand Execution Lifecycle before you proceed with the implementation.

1

List supported tokens

Use List supported tokens to find the assetId values you will need. You'll need to use the Intents API for that.

JavaScript

const response = await fetch(`https://intents-connect-alpha-api.aurora.dev/api/v1/supported_tokens`);
const tokens = await response.json();

Response explanation

The response includes tokens with their assetId in this format:

• SOL tokens: nep141:sol.omft.near

• USDC on Base: nep141:base-0x833589fcd6edb6e08f4c7c32d4f71b54bda02913.omft.near

[
  {
    "assetId": "nep141:sol.omft.near",
    "decimals": 9,
    "blockchain": "sol",
    "symbol": "SOL",
    "price": 84.79,

      }
    ],
    "type": "evm"
  })
});
const execution = await response.json();

Request data explanation

• dry is false, unless we want to get just the estimates

• metadata contains information displayed in the UI - it's optional

• quote

  • amount contains the input amount used for the action

  • destinationAsset assetId used for the action on the destination chain

  • originChain assetId deposited into the deposit account

  • slippageTolerance value is basis points, so 100 is 1%

• steps not used in the initial dry run

• type type of the action

• steps are now used, and this is how we defined an action on the destination chain

  • functionSignature function signature to be called on the EVM chain

  • parameters arguments to be passed to the function

  • to contact to interact with

  • value native value - in case a native token needs to be used

Example response

Field	Description
details.payload.payload_json	Message to be signed by the wallet
id	Identifier of the execution, needed for tracking
quote.depositAddress	Deposit account to which the transfer needs to be done
status	Status of the transaction, used for understanding the lifecycle of the execution
steps	Updated steps were built based on the user's signed input steps. The additional transfer added to the array is used to reimburse the gas fee

3

Sign the message

details.payload.payload_json needs to be signed by the Solana wallet so it can be submitted in the next step.

4

Submit the digest

Use Submit digest to submit the signed message. This will allow executing batched transactions on the destination chain.

JavaScript

const response = await fetch(`https://intents-connect-alpha-api.aurora.dev/api/v1/executions/${solanaWalletAccount}/submit`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "executionId": "92a10832-d36b-46c6-807d-7f28469c2a94",
    "publicKey": "ed25519:BTKcXNp1wSzs9Mp2ejsPrHLr59z5UkEDJgqcWyXGhGc4",
    "signature": "ed25519:5VUXRtVgS6bq3Wn64YdCt5NSPfA1Ni5zqiLFsSScyq6Dj53pbNEcwKcp7t1aRqw8zWCoN7coMLBUmatmwLAEvndP"
  })
});
const execution = await response.json();

Request data explanation

• executionId ID of the execution

• publicKey public key of the wallet

• signature signed message signature

Example response

{
  "result": {
    "status": "SIGNED_PENDING_DEPOSIT"
  }
}

5

Deposit into the deposit account

Now, deposit exactly quote.amount into quote.depositAddress so the swap can execute.

6

Monitor the status of the execution

Use Fetch executions using id of the execution

JavaScript

const response = await fetch(`https://intents-connect-alpha-api.aurora.dev/api/v1/executions/BTKcXNp1wSzs9Mp2ejsPrHLr59z5UkEDJgqcWyXGhGc4?id=92a10832-d36b-46c6-807d-7f28469c2a94`);
const execution = await response.json();

Response explanation

The response will contain the entire execution object, but look out for status the field that indicates the lifecycle of the execution. SUCCESS means the execution is fully processed.
