RPC, API and P2P.

The public node speaks Ethereum JSON-RPC, a few PSYROB methods, read-only JSON endpoints and P2P over WebSocket. Block numbers in RPC are chain heights of the selected chain.

Network

Network name	PSYROB v9 testnet
Chain ID	87869 (`0x1573d`)
Symbol and decimals	PSY, 18
RPC	`https://rpc.psyrob.com` (POST JSON-RPC; also `/rpc` on the explorer)
Explorer	`https://explorer.psyrob.com`
P2P	`wss://rpc.psyrob.com/p2p` (WebSocket; a node uses it with `--seeds wss://rpc.psyrob.com/p2p`)
Genesis	`0x822567d37026f373a602400c044122a043ec8bd8bae69c0f91c36ccf1eb766be` (check with `npm run genesis:check`)

Add to a wallet

chainId	`0x1573d`
chainName	PSYROB v9 testnet
nativeCurrency	name PSY, symbol PSY, decimals 18
rpcUrls	`https://rpc.psyrob.com`
blockExplorerUrls	`https://explorer.psyrob.com`

Use a new key for this network. Never reuse a key that was used on the old 87870 testnet.

Contracts

The EVM runs the Shanghai rules: compile contracts with evmVersion: "shanghai" (no transient storage, no blob opcodes). The system contracts and their ABIs are under Contracts and at /api/abi.

Examples

curl -s https://rpc.psyrob.com -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'

curl -s https://rpc.psyrob.com -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBalance","params":["0x0000000000000000000000000000000000000000","latest"]}'

curl -s https://rpc.psyrob.com -H 'Content-Type: application/json' \
