Assess Tasks

Assessing tasks allows project managers to accept or reject contributor work. Managers review submitted work and issue decisions in batch, updating the on-chain state for each contributor. No new tokens are minted — this transaction uses a spend-and-recreate pattern to update existing UTxOs.

Summary

The estimated wallet cost covers the transaction fee only. This transaction supports batching multiple accept/reject decisions into a single on-chain transaction.

  "task_decisions": [
    { "alias": "contributor1", "outcome": "accept" },
    { "alias": "contributor2", "outcome": "reject" }
  ],
  "initiator_data": {
    "usedAddresses": ["addr1qx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzer3n0d3vllmyqwsx5wktcd8cc3sq835lu7drv2xwl2wywfgse35a3x"],

  }
}

Field	Type	Required	Description
`alias`	`string` (Alias)	Yes	The manager's access token alias. Must be a current manager of the project.
`project_id`	`string` (GYMintingPolicyId)	Yes	56-character hex policy ID returned from project creation.
`contributor_state_id`	`string` (GYMintingPolicyId)	Yes	The contributor-state policy ID for the project.
`task_decisions`	`TaskDecision[]`	Yes	Array of decisions. Each contains: `alias` (string — the contributor's alias) and `outcome` (`"accept"` or `"reject"`).
`initiator_data`	`WalletData`	No	Object containing `usedAddresses` (string[]) and `changeAddress` (string). If omitted, the Gateway resolves wallet data from the authenticated session.

Response

{
  "unsigned_tx": "84a800..."
}

The response contains the unsigned transaction CBOR, ready for the user's wallet to sign.

Register Transaction

After the user signs and submits the transaction, register it with the state machine:

POST /api/v2/tx/register

{
  "tx_hash": "64-char hex hash from wallet.submitTx()",
  "tx_type": "task_assess"
}

No metadata is required. On confirmation, the state machine updates the assessment status for each contributor in the database.

Endpoint	Description
`GET /api/v2/projects/{project_id}/tasks`	Fetch all tasks including their assessment status per contributor
