JavaScript examples (qweb3.js)

Runnable Quantova samples using the official JavaScript client, qweb3.js.

Setup

npm install                                  # qweb3.js
export QUANTOVA_RPC=http://127.0.0.1:9933     # or https://testnet.quantova.io

Examples

File Scenario
01_transfer.js Native TQTOV transfer (connect, balance, fee, PQ-sign, broadcast)
02_contract_call.js QRC20 read + write on the QVM (Solidity ABI, keccak-256 selectors)
03_qns_resolve.js Resolve a .q name via the on-chain QNS registry
04_governance_vote.js Post-quantum conviction vote on a referendum 
node 01_transfer.js
node 02_contract_call.js
node 03_qns_resolve.js
node 04_governance_vote.js

Note on dependencies

Each file's header comment shows the idiomatic qweb3.js API for that scenario (new QWeb3(url), q.contract(abi, addr).call(...), q.qns(reg).resolve(...), wallet.create('dilithium')). The runnable body uses a small raw JSON-RPC helper (_common.js) so the examples work without installing the native @quantova WASM packages. With qweb3.js installed, swap the helper calls for the facade shown in the comments — the endpoints and flow are identical.

keccak-256 selectors (e.g. transfer(address,uint256) -> 0xa9059cbb) are shown as constants in the contract example; qweb3.js computes them via AbiCodec.functionSelector(...).
