What is Wrapped Filecoin? (EFIL)
Wrapped Filecoin (EFIL) is a DeFi compatible ERC-20 token that is pegged 1:1 with Filecoin (FIL). EFIL tokens can be used on DeFi protocols such as Uniswap or exchanged for FIL tokens. This project aims to increase accessibility to the FIL tokens, which Filecoin miners require to scale their operations.
The creation of new EFIL and the redemption of FIL are managed by a smart contract developed by Gemini and audited by Trail of Bits. Like WBTC, EFIL tokens are minted when FIL holders send their FIL tokens to the smart contract and get burned when EFIL holders send EFIL tokens to redeem FIL tokens.
Where is EFIL available?
EFIL is currently available in all jurisdictions in which FIL is supported. Please see our Areas of Availability page for more information.
How do I acquire EFIL?
Customers within jurisdictions in which FIL is supported can convert FIL to EFIL using the “Wrap” order type on the web interface and mobile app, or buy new FIL and wrap it in a single transaction.
What are the current fees to wrap and unwrap EFIL?
It costs 25 bps (0.25%) to wrap FIL and 50 bps (0.50%) to unwrap EFIL.
What does “wrap” and “unwrap” mean?
Wrapping FIL is the process of converting FIL tokens to EFIL. You can mint new EFIL tokens by wrapping a portion or all your FIL balance. Unwrapping EFIL means converting EFIL back to FIL tokens.

How long does it take to wrap FIL or unwrap EFIL?
