How It Works
Control Center
Control Center
(Any EVM Chain)
A service registered on the Sertone network. Consumer makes a standard REST call — the owner's Sertone translates it to a smart contract read and returns clean JSON.
What is the Sertone control center? A single Docker container you run on your own machine — a laptop, a Raspberry Pi, a cloud server. It connects you to the Sertone Global Network. Through its built-in web console, you browse services, register your own, manage your wallet, and monitor your earnings. Installation takes minutes. It is completely free, forever.
docker run -d --name my-sertone -p 3000:3000 -p 3002:3002 sertone/wrapper:latest
Why Smart Contract APIs?
Billions of dollars in DeFi data live on-chain, but accessing it requires blockchain-specific tooling — RPC providers, ABI parsing, hex decoding. Most developers just want a REST endpoint that returns JSON. Sertone makes that possible.
Expose any smart contract as a REST API. DeFi data, NFT metadata, governance votes — all accessible via simple HTTP calls. The owner's wrapper reads from the blockchain and returns clean JSON. Consumers never need to install Web3 libraries or manage RPC connections.
Real-world example: a financial dashboard pulls ETH/USD prices from a Chainlink price feed registered on Sertone. One REST call, one JSON response, settled in USDC — no Ethereum node required on the consumer side.
