Dependency check

Advanced detail assumes prerequisite knowledge

Before using practitioner mechanisms or engineer and auditor checks, review any unfamiliar dependency. These paths come from canonical depends_on relationships; Web3 Academy does not track completed lessons.

  1. Synthetic asset
  2. Asset versus claim

A synthetic asset is a claim or token designed to reproduce selected price exposure or payoff without giving ownership of the referenced asset.

System record

Start with the economic purpose, participants, resources, and entitlements before studying implementation detail.

Why it exists

Synthetic assets make otherwise unavailable, difficult-to-transfer, short, indexed, or composed exposures programmable without moving the referenced property itself.

Traditional-finance analogy

Swap-backed note or index-linked certificate is the closest comparison recorded for this concept.

Where the analogy stops

• The on-chain token or position depends on collateral, counterparties, oracles, issuance, redemption, and control rules rather than custody of the referenced asset.
• Tracking a price does not reproduce voting, income, redemption, legal title, market hours, or every economic feature of the reference.

Main actors

• ActorSynthetic holder
• ActorIssuer or protocol
• ActorCollateral or liquidity provider
• ActorOracle
• ActorRedeemer, liquidator, or counterparty
• ActorGovernance or administrator

Assets and claims

Assets — controlled or transformed resources

Assets are resources the mechanism moves, holds, values, or transforms.

• AssetCollateral or reserve assets
• AssetSynthetic token or position
• AssetFees and settlement assets

Claims — entitlements and corresponding dependencies

Claims are rights to value, repayment, redemption, control, or another party's performance; each depends on an obligation or system that must honor it.

• ClaimPrice-linked redemption or settlement claim
• ClaimIssuer or pool obligation

A synthetic asset reproduces selected exposure or payoff without giving its holder ownership of the referenced asset.

Why it exists

Synthetics make exposures programmable when the reference is difficult to own, transfer, short, divide, compose, or access on-chain. A tokenized form can move through DeFi, but its value still depends on issuance, collateral, counterparty, oracle, redemption, and control rules.

Traditional-finance analogy

A swap-backed note or index-linked certificate is a useful analogy. The holder owns a claim issued under a defined mechanism, not the referenced shares, commodity, currency, or index. On-chain transferability does not add legal title, voting, income, market-hours access, or redemption rights that the contract does not expressly provide.

Actors, assets, and claims

The holder owns a synthetic token or recorded position. An issuer, collateral pool, liquidity provider, or counterparty owes the selected payoff. An oracle supplies reference information. Redeemers and liquidators enforce conversion or collateral rules, while governance may change parameters or supported markets.

Collateral and settlement tokens are assets. The synthetic is a derivative exposure recorded as a price-linked claim and an issuer or pool liability. The reference asset may remain entirely outside the system.

Step-by-step mechanism

1. Define the reference, payoff, unit, price source, market hours, and settlement rule.
2. Deposit collateral, trade against a counterparty, or otherwise establish the issuer’s backing model.
3. Mint or record a synthetic liability and give the holder the matching claim.
4. Revalue exposure and apply fees, funding, or collateral rules over time.
5. Transfer, trade, redeem, settle, or liquidate through the specified mechanism.
6. Burn or close the claim and reconcile collateral, counterparty, and deficit accounts.

Balance sheet and flows

Table: Balance sheet and flows

Party or system	Asset	Claim or liability
Holder	Synthetic token or position	Price-linked payoff under stated settlement rules
Issuer or pool	Collateral, reserves, or counterclaims	Matching synthetic liability
Reference owner	No required state change	No automatic obligation to the synthetic holder

Capital flow moves collateral, purchase value, redemption value, settlement, and fees. Claim flow creates and burns the synthetic liability. Information flow supplies the reference price and market state. Return flow transfers gains from counterparties, collateral, reserves, market makers, or the issuer under the selected settlement model. Risk flow follows oracle, collateral, issuer, counterparty, redemption, liquidity, governance, and bridge dependencies.

Return source and loss allocation

Price gains are paid from counterparty losses, collateral, reserves, market makers, or an issuer’s obligations under the selected model. The reference asset’s issuer does not automatically pay. A shortfall reaches synthetic holders or other claimants according to the protocol’s collateral and deficit rules.

Engineer or auditor lens

Test mint and burn conservation, price decimals and direction, stale or closed reference markets, caps, fees, collateral ratios, transfer hooks, redemption queues, settlement timing, shutdown, governance changes, and deficit states. Interfaces must not imply ownership, income, votes, delivery, or legal recourse beyond the contract.

Synthetix’s V3 overview describes one protocol-specific architecture in which collateral vaults feed pools that allocate liquidity to derivative markets. That architecture illustrates an issuer and backing dependency; enabled markets, collateral, and product rules remain implementation- and deployment-specific.

Common misunderstandings

• “A synthetic stock is a share.” Price tracking does not create shareholder title, votes, dividends, or issuer claims.
• “Overcollateralized means fully safe.” Price gaps, oracle faults, liquidity, governance, and settlement can still create shortfall.
• “A token price proves redeemability.” Redemption depends on explicit rules, assets, capacity, timing, and control.

Compare direct ownership and layered claims in asset versus claim.

Machine-readable model

Key equations

Canonical expressions come from the structured concept record. KaTeX renders the notation, while the plain-text expression and variable table keep its meaning and units inspectable without JavaScript. Read the narrative above for the model's domain, assumptions, and rounding rules.

This concept does not require one canonical equation. Its mechanism and state transitions remain the authoritative explanation; do not invent a formula merely to make the topic look quantitative.

Assurance contract

Security properties

These structured statements define desired behavior. Their stable IDs can bind tests, invariants, specifications, audit findings, or proof results without turning descriptive review advice into an assurance claim.

Desired · not evaluated: No test, audit, or proof result is implied until scoped evidence is linked to this property.

1. SP-01Desired · not evaluated

   Issuance and redemption reconcile synthetic liabilities with the selected collateral or counterparty model

2. SP-02Desired · not evaluated

   Price sources, payoff, fees, settlement time, market hours, caps, and rounding are explicit

3. SP-03Desired · not evaluated

   The synthetic cannot confer unstated ownership, income, voting, or redemption rights

4. SP-04Desired · not evaluated

   Oracle, governance, collateral, counterparty, and deficit failure remain visible in accounting

Prerequisites

Direct dependencies recorded by this concept's canonicaldepends_on relationships.

• TokenPath 3

  A token is a programmable ledger entry that represents units a blockchain system can track and transfer.

• Asset versus claimPath 4

  The asset-versus-claim distinction asks whether a token is the resource itself or a right whose value depends on another asset or obligor.
