Actions - Enso Developer Documentation

The Bundle API supports a variety of actions to build complex DeFi strategies. This reference guide explains all available actions and their parameters.

To get the up-to date list of available actions and parameters, use GET /integration/actions.
To get a list of actions available for a specific protocol, use GET standards/{slug}/.

Chaining Actions

Bundle API allows using output of one action as the input for another.

To reference outputs from previous actions use the useOutputOfCallAt syntax. For array-outputs such as split, you can specify the index within that action’s output array

{
  "amountIn": {
    "useOutputOfCallAt": 0 // Use the output amount from the action at index 0
    "index": 1 // Optional: access outputOfCallAt[0][1]
  }
}

Here’s an example of a more complex chaining sequence that splits WETH into three different portions:

const bundle = await client.getBundleData(
  {
    chainId: 1,
    fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
    routingStrategy: "delegate"
  },
  [
    {
      protocol: "enso",
      action: "route",
      args: {
        tokenIn: "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", // USDC
        tokenOut: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
        amountIn: "1000000000" // 1000 USDC
      }
    },
    {
      protocol: "aave-v3",
      action: "deposit",
      args: {
        tokenIn: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
        amountIn: { "useOutputOfCallAt": 1, "index": 0 }, // First portion
        primaryAddress: "0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2" // Aave V3 pool
      }
    },
    {
      protocol: "curve",
      action: "deposit",
      args: {
        tokenIn: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
        amountIn: { "useOutputOfCallAt": 1, "index": 1 }, // Second portion
        primaryAddress: "0xDC24316b9AE028F1497c275EB9192a3Ea0f67022" // Curve ETH/stETH pool
      }
    },
    {
      protocol: "yearn",
      action: "deposit",
      args: {
        tokenIn: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
        amountIn: { "useOutputOfCallAt": 1, "index": 2 }, // Third portion
        primaryAddress: "0xa258C4606Ca8206D8aA700cE2143D7db854D168c" // Yearn WETH vault
      }
    }
  ]
);

Slippage Protection

Whereas the route action includes configurable slippage protection by default, but other actions require manual slippage configuration.

Always include slippage protection via the slippage or minAmountOut actions to prevent price impact.

`slippage`

Applies slippage protection specified in basis points (bps) to ensure the received amount is within the acceptable range of the expected output.

The action calculates the minimum acceptable amount based on the specified slippage tolerance (amountOut * (10000 - bps) / 10000). If the actual received amount falls below this threshold, the transaction will revert.

const bundle = await client.getBundleData(
  {
    chainId: 1,
    fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
    routingStrategy: "delegate",
  },
  [
    {
      protocol: "enso",
      action: "slippage",
      args: {
        bps: "100", // 1% maximum slippage (100 basis points)
        amountOut: { useOutputOfCallAt: 0 }, // Reference previous action's output
      },
    },
    {
      protocol: "uniswap-v2",
      action: "swap",
      args: {
        tokenIn: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
        tokenOut: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
        amountIn: "1000000000000000000", // 1 WETH
        primaryAddress: "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D", // Uniswap V2 Router
        receiver: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
      },
    },
  ],
);

`bps`	Maximum acceptable slippage in basis points (1 bps = 0.01%, 100 bps = 1%)	Yes

`minAmountOut`

Applies slippage protection specified in absolute amount (minAmountOut) to ensure the received amount is within the acceptable range of the expected output.

const bundle = await client.getBundleData(
  {
    chainId: 1,
    fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",

    {
      protocol: "enso",
      action: "minamountout",
      args: {
        amountOut: { useOutputOfCallAt: 0 }, // Reference to first action's output
        minAmountOut: "1940000000", // Minimum amount (1.94 USDC)
      },
    },
  ],
);

Parameter	Description	Required
`amountOut`	Expected output amount - must be output of one of previous actions `useOutputOfCallAt`	Yes
`minAmountOut`	Minimum acceptable amount of out token	Yes

Core Actions

`route`

The route action determines the optimal path to swap one token for another across multiple DeFi protocols supported by Enso.

This action gets expanded into a combination of swap, deposit, and redeem actions, similar to /route API. The /bundle API will return a route object that contains a list of all such actions.

When using the route action, slippage is automatically calculated and applied. The action will revert if the received amount is below the expected output after applying slippage.

For other actions, make sure to add one of slippage protection actions

const bundle = await client.getBundleData(
      {
        chainId: 1,
        fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",

Bridging

`bridge`

Facilitates cross-chain token transfers using various bridge protocols with optional callback actions on the destination chain.

When used with callback actions (callback array), it can automatically execute a series of actions on the destination chain once tokens arrive.

Important: When using callbacks, the callback bundle MUST start with a balance action to check the bridged token balance on the destination chain. Callbacks can reference outputs from previous callback actions using the useOutputOfCallAt syntax to create complex cross-chain operations. Each callback action is executed sequentially on the destination chain.

        routingStrategy: "delegate",
      },

`tokenOut`	Address of the output token	Yes
`amountIn`	Array of amounts to merge (must be in the same denomination)	Yes
`receiver`	Address to receive the merged tokens	No

`call`

Makes an arbitrary call to any contract, allowing for custom interactions. This is useful for executing complex logic or interacting with contracts that are not directly supported by the Enso API.

For example, to perform arithemtics over return values from previous actions, you can use the PercentageMathHelpers contract:

const bundle = await client.getBundleData(
      {
        chainId: 1,
        fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
        routingStrategy: "delegate",
      },
      [
        {
          protocol: "enso",
          action: "call",
          args: {
            address: "0xD0aF6F692bFa10d6a535A3A321Dc8377F4EeEF12", // Contract address
            method: "percentMul", // Method name
            abi: "function percentMul(uint256,uint256) external", // ABI signature
            args: [
              "1000000000000000000", // 1 ETH (first argument)
              "7000", // 70% (second argument)
            ],
          },
        },
      ],
    );

Parameter	Description	Required
`address`	Address of the contract to call	Yes
`method`	Name of the method to call	Yes
`abi`	ABI signature of the method	Yes
`args`	Array of arguments to pass to the method	Yes

`fee`

Calculates and deducts a fee from a specified amount, sending the fee to a designated receiver. This action is typically prepended to bridge operations to facilitate fee collection.

The fee action calculates the fee as amount * (bps/10000) and sends this amount to the receiver. It returns amount - fee, which can be used in subsequent actions via useOutputOfCallAt.

const bundle = await client.getBundleData(
      {
        chainId: 1,
        fromAddress: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
        routingStrategy: "delegate",
      },
      [
        {
          protocol: "enso",
          action: "fee",
          args: {
            token: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
            amount: "1000000000000",
            bps: "500",
            receiver: "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
          },
        },
      ],
    );

Parameter	Description	Required
`token`	Token address to apply the fee to	Yes
`amount`	Amount to apply the fee to (with full decimals) or a return value from a previous action	Yes
`bps`	Fee percentage in basis points (1 bps = 0.01%, 100 bps = 1%)	Yes
`receiver`	Address to receive the fee	Yes
