# singularityagent__transaction

Fetch and normalize a transaction, with EVM calldata decoded where the selector is recognized. If no chain is given, searches the chains the hash format allows and reports every chain it was found on. Read finality alongside status, because they answer different questions: status says the chain executed the transaction and it did not revert, while finality says whether the block holding it can still be discarded. final is the only kind that licenses an irreversible decision. reversible means it sits at or near the head and a reorganization would erase it. probabilistic is proof-of-work settlement — it carries a confirmation count and never becomes final at any depth, because the chain offers no point past which reversal is disallowed, only one past which it is expensive; how many confirmations are enough is the caller’s decision. unknown means the endpoint would not say, which is not evidence that it is settled.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `hash` | string | yes | Transaction hash, txid, or Solana signature. |
| `chain` | string | no | Chain id, to skip the cross-chain search. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "singularityagent__transaction",
    "arguments": {
      "hash": "<hash>"
    }
  }
}
```

## Why singularityagent__transaction is rated Low

Tool only retrieves and normalizes blockchain transaction data with no side effects.

From the tool's own definition: "Fetch and normalize a transaction...decoded where the selector is recognized"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call singularityagent__transaction to retrieve information from Rokha without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Rokha:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "singularityagent__transaction": {}
  }
}
```
