# getMinimumBalanceForRentExemption

> Returns minimum balance required to make account rent exempt.

Returns minimum balance required to make account rent exempt.

## On ThorNode

Answered by FastGate through the ThorEdge RPC URL; no separate endpoint or key. `commitment` and `minContextSlot` are accepted and ignored: the response reflects FastGate's indexed slot, reported as `context.slot` (no `apiVersion`). The request times out after 30 s. Computed locally from the rent formula; nothing is fetched.

## Parameters

<ParamField body="address" type="number" required>
  Size of account data in bytes that you need to store on the chain.
</ParamField>

<ParamField body="commitment" type="string">
  The commitment level for the request. Accepted and ignored by FastGate.

  * `confirmed`
  * `finalized`
  * `processed`
</ParamField>

## Response

<ResponseField name="result" type="integer">
  Minimum SOL balance in lamports required to make an account with this data size permanently rent-exempt.
</ResponseField>
