# Frequently asked questions
> Answers to common questions about SaucerSwap: getting started, swapping, order book trading, liquidity, staking, fees, tokens, and troubleshooting.
## Getting started
### How can I get started?
Create a [Hedera wallet](/get-started/wallet), [obtain HBAR](/get-started/hbar) for network fees, then follow the [quickstart](/get-started/quickstart) to make your first swap on the [web app](https://www.saucerswap.finance/).
### Where can I obtain HBAR?
You can obtain HBAR by purchasing it on centralized exchanges, using fiat-to-crypto gateways such as MoonPay or Banxa, or by swapping other tokens for it on SaucerSwap. See [Get HBAR](/get-started/hbar).
### Where can I obtain SAUCE?
SAUCE is available on SaucerSwap itself and on external exchanges. Known exchanges that list SAUCE can be found on [CoinMarketCap](https://coinmarketcap.com/currencies/saucerswap/#Markets).
### Does Hedera have a blockchain explorer like Etherscan?
Yes. [HashScan](https://hashscan.io/mainnet/dashboard) serves the same function on Hedera that Etherscan serves on Ethereum: every account, token, contract, and transaction is publicly viewable.
### Who developed the SaucerSwap protocol?
[SaucerSwap Labs](/contributors/saucerswap-labs) develops the open-source SaucerSwap protocol and maintains the web interface.
### Did SaucerSwap receive a grant?
Yes. SaucerSwap received a 20 million HBAR grant from the [HBAR Foundation](https://www.hbarfoundation.org/) (whose ecosystem role has since been absorbed into the [Hedera Foundation](https://hedera.foundation/)).
### Is SaucerSwap audited?
Yes. SaucerSwap contracts have been audited by firms including Hacken, Omniscia, and Halborn (which audited V3 in May 2026). See [Audits](/developers/security/audits).
## Trading
### What is an AMM?
An automated market maker (AMM) is a type of decentralized exchange that prices a token pair with a mathematical formula instead of matching individual buyers and sellers. Trades execute instantly against liquidity pools funded by liquidity providers.
### Can I place a limit order?
Yes. SaucerSwap V3 is a central limit order book, live on the **trade** page, where you can place limit and market orders on supported markets. See the [trade tutorial](/tutorials/trade) and the [V3 concepts page](/protocol/saucerswap-v3).
Separately, V2 liquidity providers can emulate a fee-earning limit order by depositing liquidity into a price range entirely above or below the current spot price.
### What is the difference between the trade and swap pages?
The **trade** page is the V3 central limit order book, where you place and manage limit or market orders. The **swap** page compares a V1/V2 AMM quote with an eligible V3 quote and selects a venue for your trade. See [Swap routing](/protocol/routing) for how quotes are compared.
### What is slippage?
Slippage is the difference between the expected price of a trade and the price at which it executes. It occurs on both centralized and decentralized exchanges, typically due to market volatility, large trade sizes, or low liquidity. You can set your slippage tolerance in the swap settings — see the [swap tutorial](/tutorials/swap).
### What sets SaucerSwap apart from Uniswap?
SaucerSwap is built on the Hedera Token Service (HTS), giving it high throughput and low, U.S. dollar-denominated fees. Hedera's fair transaction ordering removes the mempool-based MEV attacks seen in Ethereum protocols. SaucerSwap also offers features Uniswap does not: a central limit order book (V3), LARI liquidity incentives, a yield-bearing HBAR wrapper, and single-sided staking. See [How SaucerSwap works](/protocol/overview).
### What is a token allowance?
Hedera requires your explicit approval before SaucerSwap contracts can move tokens on your behalf. When you swap, you choose between a one-time allowance for the exact amount or a maximum allowance that avoids repeat approvals. For background, see [Hedera network security update & SaucerSwap](https://medium.com/@SaucerSwap/hedera-network-security-update-saucerswap-8d2609b43e20).
## Liquidity
### How does SaucerSwap V2 differ from SaucerSwap V1?
V2 introduces concentrated liquidity, letting liquidity providers allocate capital within specific price ranges for better capital efficiency. V2 also offers multiple fee tiers and replaces V1's yield farm with the more efficient LARI program. V2 is recommended for new liquidity positions; V1 is legacy.
### What is concentrated liquidity?
Concentrated liquidity, a feature of SaucerSwap V2, lets liquidity providers (LPs) choose custom price ranges where their capital is used to facilitate trades. Because liquidity is focused where trading actually happens, less capital achieves the same or better outcomes — higher fee yield per dollar for LPs and lower slippage for traders. All positions aggregate into one composite curve that traders trade against. See [SaucerSwap V2](/protocol/saucerswap-v2).
### What is yield farming?
In SaucerSwap V1, yield farming means staking LP tokens in the Masterchef contract to earn SAUCE and HBAR rewards pro-rata to your share of the farm. See [SaucerSwap V1](/protocol/saucerswap-v1).
### What is LARI?
The Liquidity-Aligned Reward Initiative (LARI) is V2's incentive system. Rewards are distributed automatically every two weeks to eligible V2 positions — no staking step required — and campaigns can be configured in various tokens and amounts. See [SaucerSwap V2](/protocol/saucerswap-v2).
### How are liquidity providers compensated?
Primarily through trading fees generated by swaps in their pool. On top of that, V1 offers Yield Farm rewards and V2 offers LARI rewards.
### What is the breakdown of fees?
Traders pay a swap fee on V1 and V2: fixed 0.30% on V1, and 0.05%, 0.15%, 0.30%, or 1.00% on V2 depending on the pool. V1 sends 5/6 of the fee to liquidity providers and 1/6 to BrewSaucer. V2 uses the same split by default: 5/6 (about 83.33%) to liquidity providers and 1/6 (about 16.67%) to BrewSaucer. The DAO can set a different split for each V2 pool through [governance](/governance/overview).
The protocol share funds [Unified BrewSaucer buybacks](/tokenomics/overview#unified-brewsaucer-buybacks-and-burn), allocated to xSAUCE, development, burn, and liquidity incentives. V3 order book fees work differently — see [V3 fees](/protocol/saucerswap-v3/fees).
### What is impermanent loss?
Impermanent loss occurs when the price ratio of a pooled token pair diverges from the ratio at deposit time, leaving the liquidity provider with less value than simply holding the tokens. The loss becomes permanent only if you withdraw before the ratio reverts.
### Why am I unable to create a V2 pool?
V2 pool creation is permissioned to minimize liquidity fragmentation, overseen by the [SaucerSwap DAO](/governance/overview). V1 pool creation remains permissionless.
### How do I claim my liquidity provider fees in V1?
Withdraw your liquidity. V1 fees accrue inside the pool and are reflected in the value of your LP tokens, so you receive your share automatically when you redeem them. In V2, by contrast, fees are claimed manually from the position page.
## Staking
### How can I stake my SAUCE tokens?
Go to the [stake page](https://www.saucerswap.finance/stake) and deposit SAUCE into the Infinity Pool. You receive xSAUCE, the liquid staking token, which appreciates against SAUCE as rewards accrue. Unstake at any time to realize rewards — there are no lockups. See the [staking tutorial](/tutorials/stake).
### Where do single-sided staking rewards come from?
The Infinity Pool receives 40% of SAUCE purchased through Unified BrewSaucer. Buybacks are funded by the protocol's share of V1/V2 swap fees, net V3 order book fees, and HBAR native-staking rewards earned by the WHBAR contract. The former devcut contribution to staking is now routed to burn. See [Single-sided staking](/protocol/single-sided-staking).
## Tokens
### How does the token listing process work?
The SaucerSwap interface is permissionless but tiered for user safety: tokens are categorized as default, extended, or untracked. Default tokens appear in the token menu, extended tokens require acknowledging a disclaimer, and untracked tokens must be loaded manually by token ID. For listing details, see [For projects](/resources/for-projects).
### What is a token association?
On Hedera, token association links a specific HTS token to your account. An account must be associated with a token before it can send, receive, or hold it. The SaucerSwap interface prompts you to associate tokens as needed.
### How was the SAUCE token initially distributed?
14% of the max supply (140 million SAUCE) was distributed to community members holding Planck Epoch Collectible (PEC) NFTs, based on the type and number of NFTs held. No private sales or ICOs were conducted. See [Tokenomics](/tokenomics/overview).
### What is the difference between USDC and USDC\[hts]?
[USDC](https://www.circle.com/usdc) is Circle's fiat-backed stablecoin, issued natively on Hedera as an HTS token. USDC\[hts] is a legacy asset that was bridged from Ethereum through the now-decommissioned Hashport bridge.
Hashport was permanently decommissioned on May 31, 2026, and Hashport-wrapped assets such as USDC\[hts] are permanently unredeemable on their source chains. Prefer natively issued assets, and see [Bridge to Hedera](/get-started/bridge-to-hedera) for live bridge routes.
### Does SaucerSwap support tokens with custom fees?
SaucerSwap V2 does not support tokens with custom fees. SaucerSwap V1 supports tokens with fractional fees where net-of-transfers is disabled, but not tokens with fixed fees. A workaround for fixed fees in V1 is to set a fractional fee at 0% with a fallback fee. For details on HTS custom fees, see the [Hedera docs](https://docs.hedera.com/hedera/sdks-and-apis/hedera-api/token-service/customfees).
## Troubleshooting
### Why is my transaction failing?
The two most common causes are `INSUFFICIENT_PAYER_BALANCE` (add more [HBAR](/get-started/hbar) to cover network fees) and `CONTRACT_REVERT_EXECUTED` (often fixed by raising your slippage tolerance in the interface settings). For error-by-error fixes, see [Troubleshooting](/resources/troubleshooting). If you cannot resolve an issue, open a support ticket on the [Discord server](https://saucerswap.finance/discord).
### Why can I not see my tokens in MetaMask?
MetaMask only displays tokens you have imported. Find the token's EVM address in the SaucerSwap interface or on HashScan, then import it in MetaMask. Your balance will appear once imported.
