Build DeFi that doesn't break
Bitcoin-level security meets smart contracts. No reentrancy attacks. No hidden state. Predictable costs. Built-in privacy.
// Simple ErgoScript contract
{
sigmaProp(
HEIGHT < deadline &&
PK(ownerPubKey)
)
}Why Build on Ergo?
eUTXO Model: No Surprises
No reentrancy attacks. No MEV exploitation. No hidden global state. Know exactly what your contract will cost before execution.
Sigma Protocols: Privacy Without PhD
Built-in zero-knowledge proofs. Add privacy features without cryptography expertise. Ring signatures, threshold proofs, all native.
Proof-of-Work: No Chain Halts
No rollbacks. No governance attacks. No validator cartels. Battle-tested security that just works.
Fair Launch: No Corporate BS
Zero VC premines. Zero foundation tax. Build on a chain where the community actually owns the network.
Quick Start with Fleet SDK
Get from zero to your first Ergo transaction in 3 steps
Install Fleet SDK
Add Fleet SDK to your JavaScript/TypeScript project
npm install @fleet-sdk/core
Connect to Ergo
Initialize connection to Ergo network
import { ErgoAddress, Network } from "@fleet-sdk/core";
const network = Network.Testnet;Build Transaction
Create your first Ergo transaction
const tx = new TransactionBuilder(height) .from(inputs) .to(new OutputBuilder(amount, address)) .sendChangeTo(changeAddress) .build();

Why Ergo is Different
| Criterion | Bitcoin | Ethereum | Ergo |
|---|---|---|---|
| Base Model | UTXO | Account | eUTXO |
| Smart Contract Safety | Limited | Reentrancy risks | Predictable, safer |
| Privacy Features (L1) | Transparent | Transparent | Optional (Sigma) |
| Fees & Predictability | Volatile | High, unpredictable | Low, predictable |
