Frequently Asked Questions
BASICS
What is Ferro Protocol?
Ferro Protocol is a decentralized exchange (DEX) purpose-built on the Cronos blockchain for stablecoin and pegged-asset swaps. Unlike general AMMs, Ferro Protocol uses a specialized stable-swap algorithm that minimizes slippage and impermanent loss for correlated asset pairs such as USDC, USDT, TUSD, and DAI. The protocol was developed and is powered by Cronos Labs, making it a flagship DeFi application within the Cronos ecosystem. Ferro Protocol also features a native token (FER), a staking vault (xFER), and a governance framework that allows the community to guide the protocol's development.
TRADING
How do I swap stablecoins on Ferro Protocol?
Swapping on Ferro Protocol is straightforward. First, ensure your Web3 wallet — such as MetaMask or the Crypto.com DeFi Wallet — is connected to the Cronos network (Chain ID: 25). Then visit the Swap page on Ferro Protocol, select your input token (e.g., USDC) and your desired output token (e.g., USDT). Enter the amount you wish to swap, review the displayed exchange rate, fee breakdown, and price impact, then confirm the transaction in your wallet. Ferro Protocol routes your trade through its optimized liquidity pools to deliver the best rate with minimal slippage — typically far lower than general DEXs.
TOKEN
What is the FER token and how is it used on Ferro Protocol?
FER is the native utility and governance token of Ferro Protocol. It plays a central role in the protocol's economy. Holders can stake FER to receive xFER, which accumulates protocol fee revenue over time. FER holders can participate in governance votes that shape the future of Ferro Protocol, including fee parameters, new pool listings, and token emission schedules. Additionally, staking FER (receiving xFER) allows liquidity providers to activate Pool Boost, multiplying their liquidity mining rewards. FER has a fixed maximum supply, with emissions distributed through liquidity incentives, staking rewards, and ecosystem grants.
LIQUIDITY
How can I provide liquidity and earn yield on Ferro Protocol?
To earn yield as a liquidity provider on Ferro Protocol, navigate to the Pools section and choose a pool that matches the stablecoins or pegged assets you hold. Deposit one or more of the supported tokens — you can deposit a single asset or multiple assets in any proportion. In return, you receive LP tokens representing your share of the pool. Your LP position earns a proportion of all swap fees generated by trades in that pool. You can also stake your LP tokens in Ferro Protocol's liquidity gauges to earn additional FER token rewards on top of trading fees, significantly increasing your overall yield.
STAKING
What is xFER and how does staking work on Ferro Protocol?
xFER is the liquid staking receipt token you receive when you lock FER in the Ferro Protocol Stake vault. The ratio of xFER to FER increases over time as protocol swap fees are compounded back into the vault, meaning xFER is always worth more FER than when it was issued. This makes holding xFER a passive yield strategy. Beyond yield, xFER is required to activate Pool Boost and can be used alongside eligible NFTs to multiply your liquidity mining APR. Over 424.9 million xFER tokens are currently locked in the Ferro Protocol vault, reflecting strong community commitment.
BOOST
How does the Pool Boost feature work on Ferro Protocol?
Pool Boost is a feature on Ferro Protocol that allows liquidity providers to increase their FER token reward APR beyond the base rate. To activate a boost, you must hold xFER tokens (staked FER) and optionally stake eligible Ferro Protocol-related NFTs. The boost multiplier scales with the amount of xFER and NFTs you stake relative to your liquidity position. This mechanism rewards long-term participants who hold both liquidity positions and a stake in the protocol, aligning incentives between liquidity providers and the overall health of Ferro Protocol. Pool Boost is currently live and accessible via the Pools section.
SECURITY
Is Ferro Protocol audited and safe to use?
Ferro Protocol's smart contracts have been audited by BlockSec, a well-regarded blockchain security company specializing in DeFi protocol reviews. The audit findings and reports are publicly available in the Ferro Protocol documentation. The protocol is built on battle-tested stable-swap mathematics and follows industry security best practices. Nevertheless, DeFi always carries inherent risks including smart contract vulnerabilities, market volatility, and liquidity risks. Users are encouraged to review the security documentation at docs.ferroprotocol.com and never invest more than they can afford to lose.
