# Seed Node ### Seed Node for Swisstronik Network Testnet A common way to bootstrap a node is through **`persistent_peers`**. However, they take up unnecessary computing resources once the list of peers is stale. More importantly, if you run a validator node, it can slow down the node's block signing speed and cause missing blocks. Therefore, our best practice is to only use persistent peers from nodes you absolutely trust, such as your own sentry nodes. The alternative is to bootstrap with a seed node first, use it to populate **`addrbook.json`** and then rely on **`addrbook.json`** moving forward. This typically reduces the p2p load on the server and solves the missing block issue. If you decide to use a seed node to bootstrap your node, below is our seed node for Swisstronik Testnet: ```prisma 3cb2105b9ae008f0711ca5d2e285485b6c3ad1ec@148.113.8.228:26656 ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
