# CHAIN_TX_REVERTED

**Transaction reverted on-chain**

## What happened

The transaction was accepted into a block but execution reverted. The receipt's `revertReason` (when available) names the specific contract error.

## How to fix

Decode the revert reason from the receipt. Common causes: insufficient allowance, failing `require(...)` check, out-of-gas. Re-run with `--dry-run` to simulate without broadcasting.

## Example

```ts
0g storage put ./bigfile.bin --dry-run
# Inspect the simulation output for the revert reason
```
