# E1754 — CIP-34: tlock key not yet released for this auction

| Property | Value |
| - | - |
| **Code** | `1754` |
| **Slug** | `E1754` |
| **Category** | `commit_reveal` (Commit-Reveal) |
| **CIP** | CIP-34 §Sealed-Bid |

## What happened

Cip34: tlock key not yet released for this auction.

This is the receipt's `what` text, produced by the node's `ExecutionError::TlockNotReleased`.

## Why it happened

The node rejected the operation with `E1754` (category `commit_reveal`, Commit-Reveal). The receipt's `why` field carries the specific cause and `context` carries structured details, when the emitter attaches any.

The normative rule is in CIP-34 §Sealed-Bid.

## How to fix

Fewer than t CBSS proxies have released their tlock partials yet; retry shortly — the auction auto-cancels once reveal\_height + AUCTION\_GRACE (50 blocks) passes with no release.

## Receipt example

```json theme={null}
{
  "code": 1754,

  "category": "commit_reveal",
  "what": "cip34: tlock key not yet released for this auction",
  "fix": "Fewer than t CBSS proxies have released their tlock partials yet; retry shortly — the auction auto-cancels once reveal_height + AUCTION_GRACE (50 blocks) passes with no release.",
