How to Sponsor a User Operation

To sponsor a user operation, simply specify isSponsored: true when submitting the user operation. By sponsoring the operation, your organization's gas tank will be used to pay for the gas fees, instead of the owner's individual gas tank.

Example: Submitting a Sponsored User Operation

Using the API

curl -X POST -H "Content-Type: application/json" \
-H "x-app-id: $YOUR_APP_ID" \
-H "x-signature: $CALCULATED_SIGNATURE" \
-H "x-timestamp: $TIMESTAMP" \
-d '{
    "signature": "0x.....",
    "userOpId": "67b1fc9a442f26832dadd881",
    "hash": "0x.....",
    "isSponsored": true
}' {{BASE_URL}}/api/v1/userOp/submit

Using the SDK (TypeScript)

await xellar.accountAbstraction.submitUserOp({
  userOpId,
  hash,
  signature: ownerSignature.signature,
  isSponsored: true,
});

Note:

When isSponsored is set to true, the organization gas tank will be used for the operation's gas fees.
If isSponsored is omitted or set to false, the owner's individual gas tank will be used instead.
