Celestia is a modular data availability (DA) network that securely scales with the number of users, making it easy for anyone to launch their own blockchain.

Rollups and L2s use Celestia as a network for publishing and making transaction data available for anyone to download. For them, Celestia provides high-throughput DA that can be verified easily with a light node.

#### SkyneticLabs — Celestia Testnet Infrastructure

We provide reliable endpoints, peering configuration, and bootstrap assets for Celestia testnet nodes.\
Our nodes are optimized for stability, anti-spam peers rotation, and high network availability.

#### Public Endpoints

<table><thead><tr><th width="244">Service</th><th>URL</th></tr></thead><tbody><tr><td><strong>API</strong></td><td><a href="https://celestia-t-api.skyneticlabs.com/"><code>https://celestia-t-api.skyneticlabs.com</code></a></td></tr><tr><td><strong>RPC</strong></td><td><a href="https://celestia-t-rpc.skyneticlabs.com/"><code>https://celestia-t-rpc.skyneticlabs.com</code></a></td></tr><tr><td><strong>gRPC (TLS)</strong></td><td><code>celestia-t-grpc.skyneticlabs.com:443</code></td></tr></tbody></table>

> Endpoints are monitored and auto-failover protected.

#### Quick Peering

Use our primary bootstrap peer for fast network sync:

```
PEERS="e0a647fce0b48d8e85610aa60f6094b4e0a9a461@celestia-t-peer.skyneticlabs.com:26656"
sed -i -e "s|^persistent_peers *=.*|persistent_peers = \"$PEERS\"|" $HOME/.celestia-app/config/config.toml
```

***

#### Address Book (auto-updated hourly)

```
wget -O $HOME/.celestia-app/config/addrbook.json  https://services-t.skyneticlabs.com/celestia/addrbook.json
```

This helps avoid stuck syncing due to outdated peers.

***

#### Genesis File

```
wget -O $HOME/.celestia-app/config/genesis.json https://services-t.skyneticlabs.com/celestia/genesis.json
```
