What is merge-mining with Bitcoin?

Merge-mining allows Syscoin miners to simultaneously mine Bitcoin and Syscoin with the same hash power. This gives Syscoin Bitcoin-level security without requiring dedicated mining.

Can I swap SYS without KYC?

Yes. SyntheticSwap supports SYS swaps with no registration or identity verification.

What is Syscoin's NEVM?

NEVM (Network-Enhanced Virtual Machine) is Syscoin's EVM-compatible Layer-2 smart contract platform. It's secured by Bitcoin's hash power via Syscoin's merge-mining and adds Ethereum programmability.

Rollux is an Optimistic Rollup built on top of Syscoin NEVM, providing ultra-low fees and high throughput for EVM-compatible dApps while inheriting Syscoin's Bitcoin-level security.

Z-DAG (Zero-confirmation Directed Acyclic Graph) is Syscoin's instant payment technology for asset transfers — transactions are considered final in milliseconds without waiting for block confirmation.

About Syscoin

Syscoin (SYS) is a Bitcoin-merge-mined blockchain that features a unique dual-layer architecture: the base layer (merge-mined with Bitcoin for strong security) and NEVM (Network-Enhanced Virtual Machine) — an EVM-compatible Layer-2 secured by Syscoin's PoDA (Proof of Data Availability). This makes Syscoin uniquely positioned as a bridge between Bitcoin's security model and Ethereum's programmability. NEVM enables full Ethereum compatibility while inheriting Bitcoin's hash power security. Syscoin also has a built-in decentralized marketplace for trading goods and assets without intermediaries.

How to Swap SYS

Swapping Syscoin (SYS) on SyntheticSwap is simple and requires no registration or KYC. Connect your personal crypto wallet, select SYS as your source or destination asset, enter your receiving wallet address, and confirm the live exchange rate.
