Alloy 是一組為以太坊提供類型和 RPC 客戶端實作的函式庫。

ethereum-lists/chains is the canonical metadata list for EVM chains, covering chain ID, name, native currency, and RPC URLs. Builders pull chains.json from it to populate wallet and network configuration instead of hardcoding chain data.

Chainlist is a directory of EVM chain IDs and public RPC endpoints that developers and wallets use to add a network. The repository is the source of chainlist.org.

go-libp2p 是 libp2p 的權威 Go 實作，封裝了傳輸、身分識別、DHT 和 GossipSub 模組，這些模組被普萊斯姆 (Prysm)、Lotus、Celestia 和其他需要生產級節點發現和訊息傳遞的大規模客戶端所依賴。

Helios from a16z is a portable light client that serves verified Ethereum and other chain data without trusting an RPC provider. Builders run it or embed the Rust library when an application must check the data it receives.

js-libp2p 是 libp2p 傳輸、安全、發布訂閱和節點發現的 JavaScript 實作——被 Farcaster 中心、與洛德斯塔 (Lodestar) 相關的工具以及其他鏈下協調堆疊所使用。
