Access decentralized storage with smart contracts
A Filecoin RPC node provides applications with access to FEVM (Filecoin EVM), enabling smart contracts on the world's largest decentralized storage network. Filecoin uniquely combines verifiable storage with programmability, allowing developers to build applications where data storage and computation are deeply integrated.
Most blockchains store minimal data on-chain due to cost and scalability constraints. Filecoin inverts this model — it's a blockchain designed for storing massive amounts of data with cryptographic proofs of storage. FEVM adds programmability, enabling data markets, NFT storage, compute-over-data, and applications impossible on traditional blockchains.
Filecoin advantages:
Filecoin uses Proof-of-Replication and Proof-of-Spacetime to cryptographically verify that storage providers are actually storing data. Clients make storage deals with providers, and the network continuously verifies storage through zero-knowledge proofs. FEVM runs on top of this storage layer, enabling smart contracts.
Filecoin architecture:
FEVM (Filecoin EVM) enables developers to write Solidity smart contracts that interact with Filecoin's storage layer. Smart contracts can create storage deals, verify data storage, trigger actions based on storage events, and build entirely new primitives around verifiable data storage.
This integration of computation and storage enables use cases like perpetual storage for NFTs, data DAOs, compute-over-data marketplaces, and decentralized databases.
Quick start for developers
Filecoin FEVM supports all standard Ethereum JSON-RPC methods:
const { ethers } = require('ethers');
const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/filecoin/YOUR_API_KEY');
// Verify we're on Filecoin
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 314
// Get FIL balance
const balance = await provider.getBalance('0x...');
console.log('FIL Balance:', ethers.formatEther(balance));
// Interact with storage deal contract
const STORAGE_CONTRACT = '0x...';
const storageABI = [
'function createDeal(bytes calldata, uint256, uint256) external',
'function getDealStatus(bytes32) view returns (uint8)'
];
const storage = new ethers.Contract(STORAGE_CONTRACT, storageABI, provider);
// Check deal status
const dealId = '0x...';
const status = await storage.getDealStatus(dealId);
console.log('Storage deal status:', status);from web3 import Web3
w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/filecoin/YOUR_API_KEY'))
print('Connected to Filecoin:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id) # 314
print('Latest block:', w3.eth.block_number)
# Get FIL balance
balance = w3.eth.get_balance('0x...')
print(f'FIL: {balance / 1e18}')// SPDX-License-Identifier: MIT

return true;
}
