JSON-RPC methods
Every JSON-RPC method a QRDX node serves, generated from the node and checked against testnet.
A node serves JSON-RPC 2.0 at POST /rpc (testnet: https://test.qrdx.org/rpc). This list is generated from the node's source and every method on it answered on testnet. Parameters marked ? are optional. Amounts and prices are decimal strings.
Peer-to-peer methods (
p2p_*, dht_*) are for nodes talking to each other and are not listed. The bridge_* and validator_* namespaces are not enabled on testnet.eth
Ethereum-compatible methods. Addresses may be 0x… or 0xPQ… (resolved to the account id). Only legacy (pre-EIP-1559) and type-0x51 raw transactions are accepted.
