Query Examples

Set the current testnet EVM JSON-RPC endpoint and precompile address:
Security note: Use a keystore or hardware wallet for real operations. Do not pass raw private keys directly in shell commands. 
export RPC_URL="https://test-json-rpc.cloud.aultblockchain.xyz"
export MINER_PRECOMPILE="0x0a01700000000000000000000000000000000002"

​
Direct call

cast call "$MINER_PRECOMPILE" \
  "epoch()(uint64,bytes32,bytes32)" \
  --rpc-url "$RPC_URL"

​
Call from contract

address constant MINER = 0x0a01700000000000000000000000000000000002;

function queryMinerEpoch() external view returns (uint64, bytes32, bytes32) {
    (bool ok, bytes memory out) = MINER.staticcall(
        abi.encodeWithSignature("epoch()")
    );
    require(ok, "precompile call failed");
    return abi.decode(out, (uint64, bytes32, bytes32));

Notes

  • Delegation methods are ownership-sensitive and should be called from the authorized owner’s context.
  • Pagination-style queries use pagination tuples in the ABI.
