Chain IDs & parameters
Chain IDs#
| Network | Chain id | Hex | Status |
|---|---|---|---|
Local dev chain (xdevs run --dev) and local test networks (xdevs-cli testnet init) | 7117 | 0x1bcd | Works today, local only |
Public testnet (xdevs-testnet-1) | To be announced | Coming soon | |
| Mainnet | Not planned yet |
Chain id 7117 is for local development only. Never assume a transaction signed for 7117 is safe to replay elsewhere; any two people's local chains share it.

| RPC URL | http://127.0.0.1:8545 |
| Chain ID | 7117 |
| Currency symbol | tXDS (18 decimals) |

The SDK can add the network with addXdevsChainToWallet(wallet, xdevsDevnet).
