# LayerZero on Tempo

> Overview of LayerZero on Tempo, an EVM-compatible chain with no native gas token, using LZEndpointDollar for all messaging fees.

Tempo is an EVM-compatible chain with **no native gas token**. All transaction fees are paid in USD stablecoins. LayerZero deploys [EndpointV2Alt](/v2/concepts/protocol/layerzero-endpoint-alt) on Tempo instead of the standard `EndpointV2`, with [LZEndpointDollar (LZD)](/v2/developers/tempo/reference/lz-endpoint-dollar) as the fee token. LayerZero fees are paid through ERC-20 transfers instead of `msg.value`.

<Info>
  **Developing on Tempo**: Tempo's EVM has higher opcode costs than standard EVMs, and fork testing requires [Tempo's Foundry fork](https://docs.tempo.xyz/sdk/foundry). See the [Tempo developer docs](https://docs.tempo.xyz) for more info.

<Info>
  Tempo uses EndpointV2Alt, a variant of the LayerZero Endpoint designed for chains without a native gas token. See the [EndpointV2Alt concept page](/v2/concepts/protocol/layerzero-endpoint-alt) for protocol-level details. For questions, join the [LayerZero Discord](https://discord.com/invite/ktbvm8Nkcr).
