Educational Byte: What Are Synthetic Tokens in Crypto Networks?

Something “synthetic” is something artificial by nature, a thing that mimics the “real” version. When we add this term to already artificial tokens, it doesn’t mean that these tokens aren’t “real,” but that they follow the price of another asset. It could be from gold, a national currency, a stock, a commodity, another cryptocurrency, or whatever you want. Still, synthetic tokens aren’t exactly on-chain representations of the referenced asset. If you own a synthetic token that’s tracking the price of gold, this doesn’t give you any ownership of gold itself. It just gives you exposure to the price of the involved asset: If gold rises in price, a synthetic instrument designed to follow it should move in the same direction.That’s a key difference from Real World Assets (RWAs) tokens, which indeed are a loyal representation of a concrete asset in the real world, not only its general price.How Do Synthetic Tokens Work? Smart contracts are at the heart of this type of token. They set the rules for creating, transferring, and managing synthetic positions, while collateral can support those positions. Many systems use overcollateralization, meaning more value is deposited than the value of the synthetic assets created. Overcollaterization is important here because it’s done mainly to manage the risks created by price movements and maintain the synthetic asset's backing. If a synthetic token tracks an asset whose price rises or falls, the collateral needs to provide enough value to support the outstanding synthetic positions. This mechanism creates a buffer between the value of the collateral and the value of the synthetic assets issued, ensuring their existence. Oracles are another important piece of the puzzle. To follow prices, you’ll need precise data, and crypto networks don’t have this precise data natively (unless the underlying asset is native to them). That’s why a smart contract for synthetic assets relies on oracles: they’re data feeds that transform external data into on-chain data.In this case, they bring prices of assets that are completely outside the network, like gold, bonds, or stocks, into the ledger —so the smart contract can read them to calculate values and keep synthetic instruments aligned with their targets.Benefits & Use Cases For a start, a synthetic instrument can provide exposure to an asset or market without requiring the underlying asset itself to move on-chain. That can be useful for commodities, currencies, stocks, and indexes. They can also interact with decentralized applications (Dapps). Because synthetic assets can exist as on-chain instruments, developers can build them into lending systems, exchanges, automated strategies, or other smart-contract applications. This composability gives financial products more ways to interact with one another instead of sitting in separate systems.Derivatives are another natural use case. A perpetual future, for instance, can follow the price of an asset while giving traders a tokenized position that doesn't represent ownership of that asset. Obyte’s Pythagorean Perpetual Futures offer a concrete example. Their tokens follow the prices of currencies, stocks, commodities, or crypto assets using Pythagorean bonding curves and oracle-provided target prices. Because these futures are tokens that track external asset prices rather than represent ownership of those assets, they can be considered synthetic assets. The futures never expire, and their price mechanism adjusts toward the target reported by an oracle. So synthetic tokens cover a broader idea than simply creating a digital copy of something. They turn price exposure into an on-chain, programmable instrument, opening different ways to build financial products around assets that had previously remained outside distributed networks.
