1. Store Filecoin More Conveniently with D'Cent Wallet

Have you ever felt that generating Filecoin or dealing with complex addresses and deposit methods is difficult to use?

In this guide, we will explain everything from the basic concepts of Filecoin to how you can use the D'Cent Wallet to manage it more easily and securely.

With the v7.4.4 update, D'Cent Wallet now officially supports Filecoin (FIL). This enables more direct deposits and withdrawals, making it easier to manage your assets. If you previously stored your Filecoin on an exchange or another wallet, you can now use the D'Cent Wallet for safer and more efficient asset management.

So, what exactly is Filecoin? How can you use it? And how does D'Cent Wallet make Filecoin management easier? Let's explore these questions one by one.

2. Filecoin Address System

A Filecoin network address is a unique string that identifies users. All Filecoin transactions and data storage activities occur through specific addresses, which are classified based on their prefix and numeric identifier. (f0 - ID address, f1 - general user address, f2 - smart contract address, f3 - BLS address, f4 - EVM-compatible address)

Basic Structure of a Filecoin Address

A Filecoin address always starts with "f", and the number that follows determines its type. The basic format of an address is as follows:

f<address type><unique identifier>

For example, if there is an address f01234:

• f0 → Represents an ID address,

• 1234 → The unique ID assigned to the user.

Now, let's take a closer look at the Filecoin address system.

* What is BLS Signature?

The BLS (Boneh-Lynn-Shacham) signature algorithm is a digital signature method that provides higher security with a shorter signature length compared to traditional signature methods. It is particularly useful in Multi-Sig (multi-signature) systems, where multiple signatures are aggregated into a single compact signature, increasing transaction processing speed and reducing storage space required for data.

Understanding Different Address Types

1) ID Address (f0)

The simplest address format used within the Filecoin network.

🔹Consists only of numbers and is mainly used for internal system processes.

🔹General users rarely need to use this type of address directly.

2) Public Key Address (f1)

The standard account address most commonly used by general users.

🔹Based on the SECP256K1 public key, these addresses are generated and primarily used in wallets and exchanges.

🔹Typically used for storing and transferring coins.

3) Actor Address (f2)

An address for smart contracts (actors) within the Filecoin network.

🔹Used in automated systems that execute specific tasks.

🔹Often used by service operators, such as storage providers.

4) BLS Address (f3)

An address that utilizes the BLS (Boneh-Lynn-Shacham) signature method.

🔹Offers strong security and scalability and frequently used for handling multi-signature (Multi-Sig) transactions.

5) EVM-Compatible Address (f4 or 0x)

To enhance interoperability with EVM (Ethereum Virtual Machine), Filecoin supports EVM-compatible addresses(f4).
Thus, f4 addresses in the Filecoin network can be converted to 0x addresses used in EVM, and conversely, 0x addresses in the EVM network can also be converted to f4 addresses for use in Filecoin.

📌 f4 Addresses and EVM (0x) Address Conversion

🔹f4 addresses are designed to be compatible with the EVM (Ethereum Virtual Machine) address system.

🔹Addresses starting with f410 can be converted into 0x format for seamless integration with EVM smart contracts and DApps.

✅ Example of a Filecoin Address: f410abcdef1234567890...
✅ Converted EVM address: 0xabcdef1234567890...

In summary, f4 addresses can be converted into 0x addresses, allowing them to be used within the EVM network.

📌 Why is This Important?

Filecoin continues to enhance its EVM interoperability, enabling smart contracts running on the Filecoin network to interact smoothly with EVM-based chains. Because of this, f4 addresses play a crucial role in connecting Filecoin with EVM-based DApps and smart contracts.

✅ Supports the deployment of EVM-based smart contracts on Filecoin

✅ Allows direct token transfers using EVM-compatible addresses within the Filecoin network

✅ Enables access to various EVM-integrated Web3 services (DeFi, NFTs, etc.)

If you have understood the Filecoin address system, it is also important to be aware of key considerations when actually transferring Filecoin.
Since Filecoin supports multiple address formats, you must be careful not to mix f1, f3, and f4 addresses when making transfers.

In particular, when making deposits to exchanges or wallets, it is essential to check the supported address formats in advance. For example, some exchanges may not support deposits using f4 (EVM-compatible) addresses, so you must verify this before proceeding with a transaction.

Filecoin’s official documentation also provides guidelines on safely transferring FIL, so we recommend reviewing it before making any deposits or withdrawals.

3.Manage Filecoin More Easily with D’Cent

While Filecoin supports multiple address formats, most hardware wallets and exchanges only allow transactions between f1 and f1 addresses or f4 and f1 addresses. Direct transfers between f1 and f4 addresses are usually not supported.

However, with the v7.4.4 update, Filecoin transfers between f1 and f4 addresses are now possible in D’Cent Wallet.

Additionally, f1 and f4 addresses can directly transfer to 0x addresses, and 0x addresses can be converted back to f1 or f4 addresses.

In other words, Filecoin can be used with both f1 and f4 addresses or converted to 0x format for broader compatibility and later transferred back to f1 or f4 if needed.

📌 Comparison: Most Hardware Wallets & Exchanges vs. D’Cent Wallet

With this feature, D'Cent users can transfer Filecoin from an f1 address to an EVM-linked 0x address when withdrawing from exchanges. Conversely, Filecoin can also be moved from a 0x address back to an f1 address. Similarly, f4 addresses can also transfer to 0x addresses, and 0x addresses can be converted back to f4 addresses.

📢 Important Notice

📌 "ASSETS ON THE FILECOIN NETWORK ARE NOT AVAILABLE ON ANY OTHER NETWORK."

Although Filecoin provides compatibility with Ethereum (EVM support), this does not mean that Filecoin assets can be directly used on the Ethereum network.

In other words, transferring Filecoin (FIL) tokens to an f4 or 0x address does not automatically make them usable on the Ethereum network.

✅ Filecoin assets can only be transferred within the Filecoin network and cannot be directly moved to other EVM networks (e.g., Ethereum Mainnet, Arbitrum, Optimism, etc.).

✅ D'Cent Wallet allows transfers between f1 and f4 addresses, but this does not mean they can be used directly on the Ethereum network.

💡 Using an f4 or 0x address does not mean the assets are directly transferred to the Ethereum network. Always check the network before making a transfer.

5. Conclusion

With this update, D'Cent Wallet now allows safer and more convenient storage and transactions of Filecoin (FIL).
In particular, f1 ↔ f4 address transfers, which were not previously supported by most hardware wallets and exchanges, have now been enabled, allowing for more flexible asset management within the Filecoin network.
