RPC and endpoints

The connection details and a one-command check. Everything here is testnet pre-mainnet — the chain ID reads // confirm until it is set.

Network params

Connection details.

In mono, with copy buttons. Point any standard Ethereum RPC client at the testnet endpoint — the network is EVM-equivalent, so no special client is needed.

Testnet

These values are testnet pre-mainnet and may change. The chain ID renders // confirm until the real value is published. Do not hardcode it in production.

Connect

Connect in one command.

Set OSS_RPC_URL to the testnet RPC URL above, then read the latest block height to confirm the connection.

# Set the testnet RPC, then read the latest block (testnet)
export OSS_RPC_URL="https://rpc.testnet.openstatestack.network"
cast block-number --rpc-url $OSS_RPC_URL

A non-zero block height confirms the testnet RPC is reachable. Open the same height in the explorer to cross-check.

Connected. Now deploy.

Deploy against the testnet RPC, or open the explorer to debug against live data.
