### Requirements

- attached_live_client
- rpc

### Risks

- provider_limits
- chain_reorganization

### Inputs

- `client` (CLIENT; required; positional) — Attached live CLIENT used for the current gas-price observation.

### Returns

Current gas price in Wei

Exact UINT256 quantity returned by eth_gasPrice. Use format_units(gas_price_wei, 9) to display Gwei.

- `gas_price_wei` (UINT256)

Current gas price in Wei. Exact UINT256 quantity returned by eth_gasPrice. Use format_units(gas_price_wei, 9) to display Gwei.

### Examples

_Named parameters · Needs RPC · RPC required_

```sql
WITH observed AS MATERIALIZED (
  SELECT get_gas_price($client) AS gas_price_wei
)
SELECT
  gas_price_wei,
  format_units(gas_price_wei, 9) AS gas_price_gwei,
  gas_price_wei > 0::UINT256 AS is_positive
FROM observed;
```

## Guidance

### Observation boundary

The result reflects the provider's current estimate and can change between calls.

Persist one result when downstream calculations must share the same observation.

This is a legacy gas-price estimate; EIP-1559 fee selection also depends on base fee and priority fee.
