# Gravity Longevity Testnet (L1)

## **Network Details**

* **Chain ID:** `7771625`
* **Status:** Long-running testnet — no planned resets.
* **Configuration:** See [genesis/testnet](https://github.com/Galxe/gravity-sdk/tree/main/genesis/testnet) for the exact version and network configuration.

## **Developer Resources**

* **Faucet:** [Gravity Testnet Faucet](https://faucet.gravity.xyz/)
* **Explorer:** [Gravity Testnet Explorer](https://explorer-testnet.gravity.xyz/)
* **RPC Endpoint:** [Gravity Testnet RPC](https://rpc-testnet.gravity.xyz)

## **Performance Benchmarking**

Benchmarking of the Gravity L1, conducted under controlled conditions, indicates the following performance metrics:

* **Block Time:** \~200ms
* **ERC20 Transfer Throughput:** \~**9,500 – 11,000 TPS** on a 3-validator cluster (8 vCPU / 16 GB RAM per node); limited by disk I/O persistence latency, not CPU or execution.

For detailed results and bottleneck analysis, see [3-Validator Cluster Benchmark Results](/research-and-development/benchmark-results.md).

For instructions on how to reproduce these results, refer to the [Benchmark Reproduction Guide](/research-and-development/benchmark-guide.md).
