SatLayer

• Name: SatLayer
• URL: https://satlayer.xyz/
• Category: Bitcoin restaking / shared-security / programmable slashing infrastructure
• Tags: bitcoin-ecosystem cosmos-ecosystem
• Summary: SatLayer is a Bitcoin-focused shared-security platform that uses Bitcoin and Bitcoin-derived assets as security collateral for external applications it calls Bitcoin Validated Services (BVSs). Its primary-source materials position it as a programmable slashing and rewards layer built on Babylon Genesis, with contracts, SDKs, operator tooling, and a litepaper that frame it as infrastructure for securing off-chain and on-chain services rather than as a simple staking frontend.
• What it does:
  • Lets Bitcoin restakers deposit wrapped BTC or supported Bitcoin LST assets to help secure external services
  • Provides a framework for developers to launch Bitcoin Validated Services that consume Bitcoin-backed cryptoeconomic security
  • Connects three main participant groups: Bitcoin restakers, BVS developers, and node operators
  • Implements programmable slashing, rewards distribution, delegation, vault, and service-management primitives through core protocol contracts
  • Publishes separate staking docs and developer docs, plus public code repositories for core contracts, SDKs, and tooling
• Key claims:
  • The official docs describe SatLayer as a “shared security platform” designed to use Bitcoin as the primary security collateral
  • SatLayer says it deploys a set of smart contracts on Babylon Genesis so Bitcoin can secure more programmable classes of applications than Babylon’s base primitive alone
  • The architecture docs position SatLayer as a marketplace-like framework connecting restakers, BVS developers, and node operators
  • The developer docs explicitly frame key product surfaces as vaults, services, operators, programmable slashing, and rewards
  • The litepaper page links an official downloadable PDF and a GitHub-hosted whitepaper.pdf, which is stronger documentation than many comparable restaking projects currently provide
• Whitepaper: Yes. SatLayer’s official docs include a litepaper page that links a downloadable PDF and a GitHub-hosted whitepaper.pdf; see ../whitepapers/satlayer-primary-sources-2026-04-26.md.

Internal linkages

• Best anchors: parent security-export base layer babylon, cleaner provider/consumer contrast interchain-security, and more open-ended marketplace cousin symbiotic.
