These are the canonical names for things on Arkena. We use them everywhere; you'll see them mirrored in Canton's own documentation. If a term in the wild conflicts with what's here, this list wins.
Atomic trade
A trade where every leg succeeds together or none does. On Arkena, NFT purchases and swaps are atomic — your funds either reach the seller and the asset reaches you, or nothing moves.
Capacity
The remaining amount an LP quote can serve. Decreases as fills land against the quote.
Collection
A set of NFTs sharing the same on-chain configuration (name, royalty, phases). Created by a creator.
Contract
In Canton, a piece of code that holds state and lists its signatories. Your assets exist as contracts you co-sign — moving them means archiving the old contract and creating a new one.
Deadline
The expiration timestamp on a swap intent. The matching engine stops trying to settle past this point. Range: 60 seconds to 24 hours.
DSO
Decentralised Synchronizer Operations — the entity that operates Canton's settlement infrastructure. Co-signatory on every Canton Coin contract.
Interactive submission
The Canton concept where one participant builds a transaction (knowing the indexed ledger state) and another signs the resulting hash. Arkena uses this as the basis for prepare/execute.
LP quote
An offer published by a liquidity provider to swap a stated amount of one token for another at a stated rate. Stays active across many fills until cancelled or fully consumed.
Mint phase
A configurable window in a collection launch — price, supply slice, eligibility (open or whitelist), active state. A collection can have one or many phases. Common patterns: OG → whitelist → public.
Partial fill
When a fill consumes only part of an LP quote (or only part of a sweep order). The quote's capacity decreases by the filled amount; the unfilled remainder stays active.
Party ID
A user's address on Canton. Looks like alice::1220abc… and combines a
friendly name with a cryptographic fingerprint. Public; safe to share.
PQS
Participant Query Store — the indexed read-side view of the Canton ledger that Arkena's backend uses to serve fast queries.
Prepare/execute
The two-step transaction submission flow: backend builds the transaction
(prepare), wallet signs the hash, backend submits (execute). See
The signing model.
Price impact
How much the marginal price moves between your input size and the next size up. A larger swap has more price impact because deeper liquidity quotes are at worse rates.
Primary account
The default account exposed to a connected origin. Arkena currently exposes a single primary account per origin; the API is plural-shaped to accommodate future multi-account support.
Provider
window.arkena — the JavaScript object the Arkena extension injects
into every browser tab. The dApp's API surface to the wallet.
Recovery phrase
The 24-word BIP-39 phrase that is your wallet. Anyone with these words controls every asset in it. Cannot be recovered if lost.
Royalty
A percentage of every secondary-market sale of an NFT that routes back to the creator's wallet. Set when the collection is launched; cannot be changed.
Self-custody
Holding your own keys. On Arkena, the wallet generates and stores keys locally; the platform never sees them. See Self-custody on Arkena.
Whitelist
A list of party IDs eligible to mint from a specific phase. Stored on-chain as a Merkle root; minters prove inclusion at mint time. See Launch a collection.
Settlement
The point at which a transaction is finalised on Canton. Until settlement, a trade or swap can theoretically still fail.
Signatory
A party whose signature is required for a Canton contract to be created or archived. You're a signatory on every contract that holds your assets.
SIWC
Sign-In with Canton — Arkena's authentication primitive. The Canton equivalent of SIWE on Ethereum. See Sign-In with Canton.
Slippage
The maximum acceptable difference between the quoted output and the actual filled output on a swap. Set as a tolerance percentage in the swap UI.
Sweep
Buying multiple items from a collection in a single signed action. Atomic per item — partial fills are normal.
Swap intent
A signed message expressing a swap request — input, minimum output, deadline. The matching engine matches intents against LP quotes.
Traffic cost
The Canton-network cost of a transaction, paid in CC. Typically fractions of a cent. Deducted automatically from the submitting party's balance.
TxSummary
The structured, human-readable description of a Canton transaction that the wallet renders as a card during signing.
