Pass destinationPayload + destinationGasLimit on a userOps=tx quote to run arbitrary logic atomically after tokens are delivered on the destination chain — stake, swap, vault deposit, etc.

Only supported on userOps=tx routes. Not available for deposit-address routes or Sui destinations.

Quote parameters

Field	Type	Description
`receiverAddress`	address	Your `IBungeeExecutor` contract on the destination chain — not a plain wallet.
`destinationPayload`	hex string	ABI-encoded calldata passed verbatim into `executeData`.
`destinationGasLimit`	string	Gas forwarded for `executeData` execution.

Both destinationPayload and destinationGasLimit must be set together — passing only one is rejected.

How it works

Tokens are delivered to Socket’s BungeeReceiver contract (same address on all supported chains via CREATE3), which then calls your executor:

bridge delivery → BungeeReceiver → YourExecutor.executeData(quoteId, amount, token, calldata)

BungeeReceiver pre-approves amount of token before the call, so your executor can pull from it directly.

IBungeeExecutor interface

This is the v3 / OpenRouter single-output signature. Do not use the older marketplace executor (different multi-output signature).

interface IBungeeExecutor {
    function executeData(
        bytes32 quoteId,
        uint256 amount,
        address token,
        bytes calldata callData
    ) external;
}

callData is exactly what was passed as destinationPayload at quote time.

Constraints

destinationPayload + destinationGasLimit are all-or-nothing.
Not supported on Sui or deposit-address (userOps=deposit) routes.
BungeeReceiver is deployed on all OPEN_ROUTER_CHAIN_IDS (Ethereum, Arbitrum, Base, Optimism, Polygon, BNB, Gnosis, Linea, Mantle, Scroll, Sonic, Soneium, Unichain, Worldchain, HyperEVM, and more).
CalldataExecutor (0xC914...9008) is a reference no-op executor that forwards calldata to an arbitrary target — useful for simple forwarding. No registration needed; security is handled by BungeeReceiver’s per-quote signature verification.

Quote request (TypeScript)

const route = await fetch(

    destinationPayload: "0xYourAbiEncodedCalldata",
    destinationGasLimit: "500000",
  })}`,
  { headers: { affiliate: "YOUR_AFFILIATE_ID" } }
).then(r => r.json());
