Snowside
The eCash Sidechain on Avalanche

Native BTC gas. Instant USDC bridging. Bitcoin‑security, Avalanche speed.

A Bitcoin sidechain, powered by Avalanche

Snowside is a dedicated Avalanche Layer‑1 blockchain built to host Paul Sztorc's upcoming eCash hard‑fork. It runs as a clean EVM sidechain where the native gas token is BTC itself—no new minted tokens, no pre‑mine, just the same Bitcoin security via blind merged mining.

Unlike Paul's previous EthSide chain (which was abandoned due to maintenance overhead), Snowside leverages Avalanche's subscription model and NodΞRunr automation to remain lean, resilient, and trivially operable.

The name Snowside reflects our commitment to the Avalanche ecosystem and our lineage within the family of Bitcoin sidechains that Paul already maintains.

The perfect substrate for Bitcoin sidechains

Sub‑second finality

eCash transactions confirm instantly, dramatically improving user experience over existing Bitcoin‑adjacent chains.

Sovereign validator set

Snowside runs its own validators, ensuring dedicated throughput for eCash operations.

Native interoperability

Avalanche Interchain Messaging (ICM) allows trust‑less bridging of USDC from the C‑Chain.

Low operational cost

Avalanche9000's subscription model makes community‑run validation cheap and feasible.

Tooling maturity

Full EVM compatibility—Remix, Hardhat, The Graph all work out‑of‑the‑box.

Two native assets, zero friction

Bridging Bitcoin and stablecoin economies in one network.

Snowside natively uses BTC for gas and transaction fees, preserving the economic model of Bitcoin. At the same time, a standard USDC bridge from Avalanche's C‑Chain is integrated from day one, allowing users to bring in stable liquidity without exposure to volatile assets.

No competing token. No new consensus token. Just BTC & USDC, secure and fast.

Automated node management, from launch to maintenance

Snowside is born from NodΞRunr, the lightweight daemon that won a retro9000 grant from the Avalanche Foundation for simplifying Layer‑1 operations. NodΞRunr handles one‑click deployment, custom precompile integration, 24/7 monitoring, and automatic updates.

Built for Paul Sztorc's eCash revival

Paul Sztorc (creator of Drivechain, BIP 300) has long maintained multiple Bitcoin sidechains for experimentation. His upcoming eCash hard‑fork provides a new specification for an e‑cash system that preserves privacy and scalability. However, EthSide, his original EVM sidechain, was retired because standalone chain management was too time‑consuming.

Snowside fills that gap. We have coordinated with Paul to ensure the L1's configuration meets the eCash specification. By leveraging Avalanche and NodeRunr, we give Paul and his community a chain that they can actually use – without babysitting.

Who builds Snowside

Snowside is a project by 0xShomari (creator of NodΞRunr).

  • ✅ Received a $10,000 retro9000 grant from the Avalanche Foundation
  • ✅ NodΞRunr is open source and already used by multiple Avalanche L1 teams
  • ✅ Direct support from Paul Sztorc (informal collaboration)

Current status: Applying for a Team1 Mini Grant to fund the final launch and community onboarding.
