A modular financial system built on Bitcoin's security
Sidecoin connects multiple Drivechains into a unified financial hub — bringing payments, privacy, smart contracts, identity, and more to Bitcoin.
Drivechains are Bitcoin sidechains enabled by BIP-300 (Hashrate Escrows) and BIP-301 (Blind Merged Mining). Each chain extends Bitcoin with new capabilities — payments, privacy, smart contracts, identity — without changing Bitcoin's core protocol.
Each chain adds a specific capability to Bitcoin. Payments, privacy, smart contracts, and more — each as a purpose-built sidechain.
All Drivechains are secured by Bitcoin's full SHA-256d hashrate via merged mining. No new tokens, no separate validator sets.
Sidecoin abstracts chain complexity. You interact with a single wallet — the sidechains operate seamlessly behind the scenes.
Each assigned sidechain occupies a sparse BIP-300 slot and is secured by Bitcoin's full hashrate via Blind Merged Mining (BIP-301). Announced chains without final assignments display Slot TBD. Click any chain to learn more.

Sidecoin handles the complexity so you don't have to.
You interact with Sidecoin as a single wallet. No manual chain switching, no separate apps, no complex configuration.
When you make a payment, swap an asset, or use a smart contract, Sidecoin routes your action to the appropriate sidechain automatically.
Funds move between chains through BIP-300 deposits and withdrawals. Sidecoin manages these transfers so your assets are always where they need to be.
Under the hood: BIP-300 Hashrate Escrows manage sidechain deposits and withdrawals with a ~6 month withdrawal window (26,300 blocks). BIP-301 Blind Merged Mining allows Bitcoin miners to secure all sidechains simultaneously without running additional node software.
Drivechains expand what Bitcoin can do without changing Bitcoin's core protocol.
Every sidechain is secured by Bitcoin's full SHA-256d hashrate through merged mining. No new consensus mechanisms, no additional trust assumptions. The same miners that secure Bitcoin secure every Drivechain.
Instead of overloading a single blockchain, Drivechains distribute functionality across purpose-built chains. Each chain can optimize for its specific use case — payments, privacy, smart contracts — without bloating the mainchain.
Bitcoin DeFi, Bitcoin privacy, Bitcoin smart contracts, Bitcoin prediction markets — all secured by Bitcoin miners, all accessible through a single wallet. Drivechains make Bitcoin a complete financial platform.
Sidecoin brings these chains together into a single, seamless experience. One wallet, eight sidechains, unlimited possibilities.
