What is
Atomic Swap?
A trustless exchange of cryptocurrencies that either completes entirely or not at all.
Atomic swaps use cryptographic techniques (hash time-locked contracts) to enable trustless trading between parties. The 'atomic' property means the swap either executes completely for both parties or fails entirely - no partial execution. Ergo's eUTXO model makes atomic swaps natural and secure.
Key Points
- All-or-nothing execution
- No trusted third party needed
- Uses hash time-locked contracts
- Natural fit for eUTXO model
- Enables cross-chain trading
- No counterparty risk

Common questions about this topic
How to get started with Ergo?
Start by getting a wallet (Nautilus for browser, Terminus for mobile). Back up your seed phrase securely offline. Get some ERG from an exchange (Gate.io, KuCoin) or DEX (Spectrum). Make a test transaction. Then explore: try DeFi on Spectrum, check out NFTs, or dive into the technology if you're a builder.

What are NiPoPoWs and why do they matter?
NiPoPoWs (Non-Interactive Proofs of Proof-of-Work) are cryptographic proofs that compress blockchain history. Instead of downloading gigabytes of blocks, light clients can verify the chain with just kilobytes of data. This enables true trustless light wallets, efficient cross-chain bridges, and sidechains - all without trusting third parties.

How to build DeFi on Ergo?
Building DeFi on Ergo starts with understanding the eUTXO model and ErgoScript. Unlike account-based chains, Ergo's box model provides deterministic execution, no MEV by design, and predictable gas costs. Use Oracle Pools for price feeds, and leverage existing patterns from Spectrum Finance and SigmaUSD.

Is Ergo a good investment?
This is not financial advice. Ergo has strong fundamentals: fair launch (no VC dump risk), innovative technology (eUTXO, Sigma Protocols, NiPoPoWs), active development, and a cypherpunk ethos. It's a smaller market cap project with higher risk/reward than established chains. Research thoroughly, understand the technology, and never invest more than you can afford to lose.
