Activities & Events

After executing a plan, you’ll want to track its progress. Legend provides two complementary mechanisms.

Activities

Activities represent completed or in-progress on-chain operations. Each activity contains:

id — Unique activity identifier
status — Current state: "pending", "completed", or "failed"
quark_intent — The original intent that created this activity (if applicable)
executions — A list of on-chain executions that make up the activity

{

      ]
    }
  ]
}

Use List Activities to see all activities, or Get Activity for a specific one.

Quark Intent

When an activity was created from a plan, the quark_intent field contains the original intent:

Field	Description
`id`	Intent identifier
`mercator_version`	Version of the Mercator engine used
`intent_type`	The type of intent (e.g., `"transfer"`)
`intent`	The full intent parameters

Activity lifecycle

pending → completed    (all executions confirmed on-chain)
pending → failed       (any execution reverted)

An activity’s status is derived from its executions:

failed if any execution reverted
pending if any execution is still pending
completed only when all executions have succeeded

Executions

Each execution represents a single on-chain transaction within the activity:

Field	Description
`execution_type`	`"transaction"` (quark execution) or `"external"` (exogenous execution)
`chain_id`	The chain this execution occurred on
`transaction_hash`	Hex-encoded transaction hash
`status`	`"pending"`, `"executed"`, or `"failed"`
`executed_at`	When the execution was confirmed
`reverted_at`	When the execution reverted (if applicable)
`actions`	List of expected and observed actions

Actions

Each execution contains a list of actions. Every action has:

action_type — The type of on-chain action (see below)
expected_values — What was intended at plan time
observed_values — What actually happened on-chain (populated after execution)

Comparing expected_values to observed_values lets you verify that the execution matched the plan.

Action Types

Each action’s expected_values and observed_values follow a schema determined by the action_type. The fields below describe the body for each type.

Events

Events provide a real-time stream of changes to a sub-account. Use them for:

Webhooks-style monitoring — Long-poll for updates instead of repeatedly fetching activities
Cursor-based pagination — Track where you left off with the cursor value

Long-polling

Pass poll=true to the Events endpoint and the request will hang until new events arrive (up to ~30 seconds). This is more efficient than polling activities on a timer.

GET /accounts/acc_xxx/events?since=0&poll=true
→ hangs until an event occurs
→ returns events + new cursor

When to use which

Use case	Recommended
Show transaction history	Activities
Wait for a specific transaction to confirm	Events (long-poll)
Build a real-time dashboard	Events (long-poll loop)
Debug a failed transaction	Activity (by ID)
Verify execution matched the plan	Activity actions (expected vs observed)
