RPC Endpoints
Mainnet
| ChainID | 248 | ||
| Currency Symbol | OAS | ||
| RPC | Oasys | HTTPS | https://rpc.mainnet.oasys.games |
| Websocket | wss://ws.mainnet.oasys.games/ | ||

For those using eth_newFilter on the Oasys HTTP endpoint, please switch to using WebSocket. Since the Oasys RPC endpoint is load-balanced, there is no guarantee of accessing the same node each time. If you encounter the error filter not found when you call eth_getFilterChanges, it means that your request is being processed by a different node than the one where the filter ID was generated. The testnet is the same.
Testnet (Hub Layer)
| ChainID | 9372 | |
| Currency Symbol | OAS | |
| RPC | HTTPS | https://rpc.testnet.oasys.games |
| Websocket | wss://ws.testnet.oasys.games/ | |
| Explorer | https://explorer.testnet.oasys.games/ | |
| Faucet | https://faucet.testnet.oasys.games/ | |
If you're planning to run a testnet node, please use our provided snapshot for setup. Due to a technical issue (an invalid block accidentally created in the past), the current testnet is unable to fully sync with other full nodes.
