# Base Chain — Full Context

> Full context for agents working with Base Chain. Hand-written network, freshness, and
> routing guides sit above an exhaustive per-route index.

## Network state
- [Base Chain](https://chain.base.org/): Dashboards and tools for Base Chain, in one place.
- [Snapshots · Base Chain](https://chain.base.org/snapshots): Download the latest Base node snapshots for Mainnet and Base Sepolia to sync a node quickly. (changes daily; re-fetch before relying on it)

## Vibenet developer network
- [Vibenet · Base Chain](https://chain.base.org/vibenet): Explore Vibenet, the Base devnet for testing in-flight protocol features.
- [Accounts · Vibenet](https://chain.base.org/vibenet/demos/account): Create native account abstraction accounts from in-browser keys, fund them from the faucet, and inspect balances on Vibenet.
- [Tokens · Vibenet](https://chain.base.org/vibenet/demos/b20): Explore, configure, and issue Base-native B20 tokens on Vibenet.
- [Validity Transactions · Vibenet](https://chain.base.org/vibenet/demos/validity): Explore Vibenet demos built with transactions that execute only while their onchain validity conditions hold.
- [Conditional Swaps · Validity Transactions](https://chain.base.org/vibenet/demos/validity/conditional-swaps): Place a validity-backed swap on Vibenet that waits for a target price, then fills or expires as the market moves.
- [Race the Agent · Validity Transactions](https://chain.base.org/vibenet/demos/validity/race-the-agent): Compare a manually timed VIBE withdrawal with a validity transaction that is already waiting for its onchain condition.
- [Explorer · Vibenet](https://chain.base.org/vibenet/explorer): Browse blocks, transactions, and addresses on the Vibenet devnet. (changes daily; re-fetch before relying on it)
- [Faucet · Vibenet](https://chain.base.org/vibenet/faucet): Request testnet tokens on Vibenet to fund accounts and try in-flight Base features. (changes monthly; re-fetch before relying on it)

## Machine-readable endpoints
- [Chain health](https://chain.base.org/api/health): JSON liveness probe for the chain.base.org service. Call this instead of parsing the homepage.
- [Snapshots manifest](https://chain.base.org/api/snapshots): JSON array of the latest node snapshots per chain: chainId, chainName, block height, timestamp, client version, profile, total byte size, and a per-component breakdown. Call this instead of scraping /snapshots.

## Network reference
- [Base Mainnet — chain ID 8453](https://docs.base.org/base-chain/quickstart/connecting-to-base): RPC https://mainnet.base.org, explorer https://basescan.org.
- [Base Sepolia — chain ID 84532](https://docs.base.org/base-chain/quickstart/connecting-to-base): RPC https://sepolia.base.org, explorer https://sepolia.basescan.org.
- [Vibenet (ephemeral devnet)](https://chain.base.org/vibenet): Chain ID and RPC are not stable and are deliberately not listed here. Read them from https://chain.base.org/vibenet at request time. State may be wiped without notice.
- [Base Sepolia faucets](https://docs.base.org/base-chain/network-information/network-faucets): Testnet funds for Base Sepolia.

## Optional
- [Base documentation index](https://docs.base.org/llms.txt): Every Base documentation page with titles and summaries. Go here for implementation detail.
- [Base documentation full context](https://docs.base.org/llms-full.txt): Full static documentation bundle for long-context runs.
- [Base docs AGENTS.md](https://docs.base.org/AGENTS.md): Compact directory-grouped index of Base documentation.
- [Base docs MCP](https://docs.base.org/mcp): Model Context Protocol endpoint for querying Base documentation directly.
- [Base website AGENTS.md](https://www.base.org/AGENTS.md): Product, ecosystem, and use-case routing for base.org.
- [Base Chain routing rules](https://chain.base.org/AGENTS.md): Full agent routing document for this site, including freshness and volatility guidance.
