Glossary
The terms these docs use.
| Term | Meaning |
|---|---|
| Account id | The 20-byte key an account's balance lives under. A 0x… address is its own account id; a 0xPQ… address maps to one by a fixed hash. See Accounts. |
| Clearinghouse | The perpetuals engine. It holds all perps collateral in one protocol account and settles profit and loss between traders' records. See Perpetuals. |
| Epoch | 32 slots. Finality is tracked per epoch. |
| Exchange nonce | A per-account counter for exchange transactions, separate from the account nonce used by EVM transactions. |
| Exchange transaction | A JSON transaction for the native exchange and native tokens (orders, swaps, pools, perps, token operations), signed with an ML-DSA-65 key. See Exchange transactions. |
| Funding | Hourly payments between perpetual longs and shorts that keep the contract price close to the oracle price. |
| Mark price | The price perps margin, liquidations and unrealized PnL use: a robust blend of the oracle price and the order book, held within ±5 % of the oracle. |
| ML-DSA-65 | The Module-Lattice Digital Signature Algorithm at security category 3, standardised by NIST in FIPS 204 (formerly CRYSTALS-Dilithium3). QRDX's post-quantum signature. Public keys are 1,952 bytes, signatures 3,309 bytes. |
| Native token | A fungible token that is data in consensus (a registry entry plus balances), not a contract. Every native token is also an ERC-20 inside the EVM. See Native tokens. |
| Oracle price | The stake-weighted median of the external prices validators vote on chain, used by perps. |
| Pool | A concentrated-liquidity automated market maker for one pair at one fee tier. |
0xPQ… address | A post-quantum account's address: 0xPQ and the first 32 bytes of keccak256 of its ML-DSA-65 public key, checksummed. |
| QRDX Connect | The encrypted relay that lets a site reach QRDX Wallet on another device by QR code. |
| Slot | Two seconds. Each slot has one proposer; a slot may pass without a block. |
| Testnet | The public test network. Its tokens have no value. |
Type 0x51 transaction | An EVM transaction signed with an ML-DSA-65 key (0x51 is ASCII Q). The sender is derived from the embedded public key. |
