Simplify's Take

What believers are saying

  • Atlas launched April 15, 2026, simplifying BTC, Lightning, ETH, USDT, and USDC bridging.
  • Q2 2026 saw over $60 million in tokenized assets settled on Rootstock.
  • Q1 2026 reports 84.01% of Bitcoin hash rate securing Rootstock, strengthening credibility.

What critics are saying

  • PowPeg and bridge assumptions create an existential exploit risk if attackers drain rBTC reserves.
  • Stacks, Bitlayer, and Citrea outcompete Rootstock on liquidity, mindshare, and developer incentives.
  • Rootstock still depends on partner adoption; 2026 traction can reverse after grants slow.

What makes RootstockLabs unique

  • Rootstock has 100% uptime since 2018 and 3,000+ uninterrupted days by July 2026.
  • Rootstock combines Bitcoin merged mining with EVM compatibility, attracting Solidity developers.
  • RootstockLabs ships Bitcoin-native infrastructure like Atlas and Union Bridge for BTCFi.
