Build on SciChain

A fully EVM-compatible, post-quantum Layer 1 that pairs on-chain verification with off-chain storage — keep hashes and metadata on-chain while heavy data lives in IPFS or your own database. Your existing Ethereum toolchain just works.

Quickstart guide API reference

Smart contracts

Deploy Solidity 0.8.x contracts on a fully EVM-compatible chain with Hardhat, Foundry, or Remix.

Post-quantum security

Every transaction is co-signed with ECDSA and NIST FIPS 204 ML-DSA — quantum-safe on mainnet today.

Instant finality

QBFT consensus finalizes blocks in ~2 seconds with no reorgs — ideal for payments and certificates.

Quickstart

Ship your first contract in minutes

SciChain is fully EVM-compatible — MetaMask, Hardhat, Foundry, Remix, ethers, and web3.js all work out of the box.

1Add SciChain to your wallet

One click with MetaMask, or add the network manually with these parameters.

network parameters

Network name:    SciChain
RPC URL:         https://rpc.scimatic.net
Chain ID:        481
Currency symbol: SCI
Block explorer:  https://explorer.scimatic.net

2Get SCI for gas

SCI is the native coin that pays for gas on SciChain. Swap into SCI or bridge assets from other chains:

3Deploy with Hardhat

Point your existing Hardhat project at SciChain — no plugins or custom tooling required.

hardhat.config.js

// hardhat.config.js
require('@nomicfoundation/hardhat-toolbox');

module.exports = {
  solidity: '0.8.24',
  networks: {
    scichain: {
      url: 'https://rpc.scimatic.net',
      chainId: 481,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};

bash

npx hardhat ignition deploy ./ignition/modules/MyToken.js \
  --network scichain

4Or deploy from Remix

Prefer the browser? Open Remix IDE, write your Solidity contract, and pick Injected Provider — MetaMask as the environment while connected to SciChain. Compile, deploy, and verify the result on the block explorer.

API reference

Standard JSON-RPC, no surprises

SciChain exposes the standard Ethereum JSON-RPC API at https://rpc.scimatic.net. Anything that speaks Ethereum speaks SciChain.

Method	Description
eth_chainId	Returns the chain ID (0x1e1 = 481)
eth_blockNumber	Number of the most recent block
eth_getBalance	SCI balance of an address
eth_gasPrice	Current gas price in wei
eth_call	Execute a read-only contract call
eth_estimateGas	Estimate gas for a transaction
eth_sendRawTransaction	Broadcast a signed transaction
eth_getTransactionReceipt	Receipt and status of a mined transaction
eth_getLogs	Query contract event logs

latest block number

curl -s https://rpc.scimatic.net \
  -X POST -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

balance of an address

curl -s https://rpc.scimatic.net \
  -X POST -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0xYourAddress","latest"],"id":1}'
