eCash Hard Fork Countdown
2026-08-21 15:00 UTC · Block ~964,000
Sidecoin is a multi-platform wallet built for the upcoming eCash hard fork (block ~964,000, August 21 2026). It supports BIP-300 Hashrate Escrows and BIP-301 Blind Merged Mining — enabling trustless sidechains secured by Bitcoin's full SHA-256d hashrate.
Native app powered by Tauri + Rust. Full node connectivity, hardware wallet support, and BIP-300 deposit/withdrawal management.
React Native app for Android (F-Droid) and iOS. QR scanning, biometric auth, and lightweight SPV mode for on-the-go payments.
Browser-based wallet (coming soon). No install required — connect to your node and manage sidechains from any device.
Each sidechain occupies a BIP-300 slot and is secured by Bitcoin's full hashrate via Blind Merged Mining (BIP-301).
Payment channel network for instant, low-fee transactions. Lightning-compatible layer for everyday payments.
