Synths protocol docs

Learn how Synths turns staked project tokens into synthetic liquidity for traders, and how trading fees flow back to stakers as real, sustainable yield.

For stakers

Stake supported assets, back synthetic markets, and earn a share of trading fees. Yield is powered by trader activity, not token emissions.

For projects

List your asset on Synths to turn your token into productive liquidity. As more users stake it, more synthetic depth becomes available for traders.

For traders

Trade synthetic exposure to listed assets without sourcing spot. Deep, synthetic liquidity backed by staked tokens.

Overview

Synths is a synthetic liquidity protocol for crypto projects. When a project's token is listed on Synths, holders can stake that token into a non-custodial vault. The protocol uses this staked liquidity to power a synthetic market for that asset.

Traders don't need to own or borrow the real token—they trade a synthetic representation instead. Trading fees from this synthetic market flow back to stakers as yield.

Key idea

More tokens staked → more synthetic liquidity → more trading activity → more fees → higher APR for stakers. No project needs to deposit USDC rewards.

What Synths is

  • A synthetic liquidity layer for project tokens
  • A way for holders to earn fee-backed yield
  • A venue for traders to long/short synthetic assets

What Synths is not

  • Not a traditional yield farm or emissions program
  • Not a custodial CeFi platform
  • Not a place where projects have to deposit USDC

How Synths works

At a high level, Synths connects stakers, projects, and traders in a single flywheel:

  1. A project is approved and listed as a supported asset.
  2. Holders stake the token into the Synths vault for that market.
  3. The protocol mints synthetic liquidity units for that asset (e.g. sBRETT, sAERO).
  4. Traders use these synthetic units to open long/short positions.
  5. Every trade pays fees; fees are streamed back to stakers as yield.
1. Stakers

Deposit project tokens into Synths vaults.

2. Synthetic liquidity

Protocol mints synthetic exposure (sAssets).

3. Traders

Trade synthetic assets and pay fees.

4. Fee yield

Fees are distributed back to stakers.

Internally, Synths uses a delta-neutral design: the protocol aims not to take directional price exposure, but instead collects fees from trading activity while managing inventory and risk.

Staking

Staking on Synths turns you into a liquidity backer for synthetic markets. When you stake a supported asset, you are helping underwrite traders' ability to take synthetic exposure to that asset.

What you earn

  • A share of all trading fees generated in that market
  • Yield that scales with volume, not inflation
  • Exposure to the underlying asset's price (unless hedged externally)

Basic staking flow

  1. Connect your wallet on the Synths app.
  2. Select a supported market and approve the token.
  3. Stake your desired amount into the vault.
  4. Watch your fee share accrue over time.
  5. Claim fees and unstake when you're done.
Important

Some markets may enforce minimum lock periods or cooldowns for risk management. Always review the market parameters in the app before staking.

Synthetic trading

Synthetic trading is the engine that powers yield on Synths. Instead of trading the real token, traders interact with synthetic exposure backed by staked assets.

Why synthetic trading?

  • Traders can take large positions without sourcing spot liquidity.
  • Markets can have deep, virtual liquidity even if the token isn't heavily traded on DEXes.
  • The protocol can fine-tune fees, spreads, and risk parameters per market.

How synthetic trading fuels yield

Every trade on Synths generates fees:

  • Open/close fees
  • Funding payments between long/short sides
  • Liquidation penalties

These fees are aggregated and distributed to stakers in that market. The result:

Yield flywheel

More staked assets → more synthetic liquidity → more trading volume → more fees → higher APR → more staking.

From a trader's perspective, Synths looks and feels like a high-liquidity, perp-style synthetic venue. From a staker's perspective, it is a way to earn fee-backed yield by supporting those markets.

Project listings

Synths lists a curated set of crypto assets. When your token is listed:

  • Holders can stake it to back synthetic markets and earn fees.
  • Traders can gain synthetic exposure to your asset.
  • Your token becomes productive liquidity, not passive supply.

What we look for

  • Real users and evidence of product–market fit
  • On-chain liquidity and sustainable token design
  • Security posture (audits, formal reviews, transparency)
  • Clear communication channels and responsive team

The application collects high-level information about your project, token, current liquidity, and how you intend to promote and support a Synths-powered market.

Security & FAQ

Synths is designed with security and risk management at the core. Smart contracts are intended to be battle-tested and progressively hardened over time.

Security principles

  • Non-custodial vaults – users stay in control of funds.
  • Isolated markets – risk is compartmentalised per asset where possible.
  • Conservative defaults on fees, leverage, and parameters.

Frequently asked questions

Do projects need to deposit USDC for rewards?

No. Yield on Synths is driven by trading fees from synthetic markets. Projects can optionally support their listing with marketing or incentives, but they do not need to fund USDC rewards directly.

Can stakers lose money?

Stakers take on protocol risk and, in some designs, may share losses under extreme conditions. Always review the specific risk disclosures for each market before staking.

How is Synths different from a DEX or AMM?

DEXes and AMMs rely on spot liquidity. Synths focuses on synthetic liquidity: traders interact with synthetic exposure, backed by staked assets and managed through internal risk systems, while fees flow back to stakers.
