This guide offers a technical walkthrough for developers building on the Frax Finance Ecosystem. We'll focus on interacting with the Frax Ether liquid staking derivative and preparing for Fraxchain.
Step 1: Minting Frax Ether (frxETH)
The primary liquid staking token of the ecosystem is Frax Ether (frxETH). This is not a rebasing token, making it much easier for DeFi integrations.
Integration: To create a Mint frxETH Guide within your DApp, you will interact with the frxETHMinter contract.
Process: Users deposit ETH and receive an equivalent amount of frxETH. The contract automatically stakes the deposited ETH with Frax's validator nodes.
Step 2: Accruing Staking Rewards with sfrxETH
To earn staking yield, frxETH must be staked in a vault, which wraps it into sfrxETH.
Mechanism: sfrxETH is a yield-bearing token. Its value increases relative to frxETH as staking rewards from the validators are added to the vault.
Implementation: Your application should call the deposit() function on the sfrxETH vault contract to Stake frxETH. To unstake, call withdraw().
Step 3: Understanding Protocol Stability (AMO)
The stability of the FRAX Stablecoin is managed by a series of Frax Algorithmic Market Operations (AMO) controllers. These are autonomous smart contracts that perform open market operations to defend the peg. While your DApp may not interact with them directly, understanding that this automated system provides stability is key to answering "Is Frax Finance Safe?".
Step 4: Preparing for Fraxchain
As per the official Fraxchain Explained documentation, Fraxchain is an upcoming L2 rollup. Developers should anticipate bridging frxETH, FRAX, and the Frax Share (FXS) Token to this new environment for enhanced scalability and lower transaction costs.
