Infura Network Endpoints Reference
This document aligns with the official Infura/MetaMask endpoint list. Replace <YOUR-API-KEY> with your API key from the MetaMask Developer dashboard — in this repo that is INFURA_PROJECT_ID in .env.

WebSocket URLs
Same host path as HTTPS; use wss://<host_path>.infura.io/ws/v3/<YOUR-API-KEY>. Example: wss://mainnet.infura.io/ws/v3/<YOUR-API-KEY>.
Gas API
The Gas REST API supports many chain IDs. Scripts use INFURA_PROJECT_ID (or INFURA_GAS_API) for https://gas.api.infura.io/v3/<ID>/networks/<chain_id>/suggestedGasFees. See scripts/deployment/check-balances-gas-and-deploy.sh and scripts/lib/infura.sh.
How we use these
.env: SetINFURA_PROJECT_IDand optionallyINFURA_PROJECT_SECRET. Per-chain URLs can be set as*_RPC(e.g.ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/<ID>) or left unset so scripts build them fromINFURA_PROJECT_IDviascripts/lib/infura.sh(build_infura_rpc(host_path)).config/infura-rpc-urls.conf: Lists host paths (e.g.mainnet,arbitrum-mainnet) for reference and for scripts that build URLs.- Verification:
scripts/deployment/verify-all-rpcs.shtests all RPC endpoints defined in.env(required, Infura, and other chains). Run from a network that can reach Infura and other RPCs.
Note: Cronos is not on Infura; use CRONOS_RPC_URL=https://evm.cronos.org or another public RPC.
