An EVM-compatible blockchain combining Bitcoin merge-mined security with a dual UTXO+NEVM architecture, enabling low-cost ZK-rollups and Rollux Layer-2 scalability for web3.
Syscoin is a Bitcoin-merged-mined Layer 1 that fuses a UTXO base chain with an Ethereum-compatible smart contract environment (NEVM), enabling EVM dApps while inheriting Bitcoin-grade security. Typical NEVM gas fees (paid in SYS) are under $0.01 at ~1–2 gwei, blocks target ~60 seconds, base EVM throughput is Ethereum-like (~15–30 TPS), and its Z-DAG layer supports near-instant, high-throughput payments for commerce, gaming, and remittances.
Syscoin is unique for combining PoW security anchored to Bitcoin with an EVM runtime, fast low-cost settlement via Z-DAG, and a rollup-ready design that powers scalable L2s like Rollux. Compared with Ethereum L1 (higher fees, ~12–15s blocks) or faster but less Bitcoin-secured alt-EVM chains, Syscoin offers ~60s blocks with rapid probabilistic settlement and sub-cent gas, leveraging merged mining to deliver robust, decentralized hash power for dApps and cross-chain bridges.
Syscoin uses SYS as the gas token for transaction fees. You can obtain SYS by bridging from other chains or purchasing using thirdweb Bridge.
To bridge SYS to Syscoin, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Syscoin as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Syscoin you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Syscoin to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send SYS on Syscoin, ensure your wallet is connected to the Syscoin network, enter the recipient's address, specify the amount of SYS to send, review the gas fee, and confirm the transaction in your wallet.
