What is SatLayer (SLAY)?

Deep Dive

1. Purpose & Value Proposition

SatLayer aims to unlock Bitcoin’s $1 trillion market cap as productive collateral for DeFi, RWA tokenization, and institutional finance. By restaking BTC or liquid staking tokens (e.g., cBABY), users secure decentralized services like cross-chain bridges or insurance protocols while earning rewards (Luke Xie, SatLayer CEO). This addresses Bitcoin’s historical underutilization in DeFi, positioning it as a trust layer for Web3.

2. Technology & Architecture

Built atop Babylon Chain, SatLayer combines Bitcoin’s security with Ethereum-like programmability. Key innovations:
- Programmable Slashing: Custom penalties for misbehavior in BVS protocols (e.g., invalid oracle data).
- Liquid Restaking Tokens (LRTs): Users receive cBABY tokens representing restaked BTC, tradable across chains.
- Cross-Chain Compatibility: Integrates with Sui, Berachain, and Ethereum for multi-chain security solutions.

3. Tokenomics & Governance

SLAY’s utility spans staking rewards, governance, and ecosystem access:
- Staking Vaults: Users lock SLAY for 30–60 days to earn BTC or boosted SLAY rewards (SatLayer Docs).
- Governance: Token holders vote on slashing parameters, BVS approvals, and treasury allocations.
- Supply Control: Fixed total supply of 2.1B tokens, with 21% allocated to staking rewards and community incentives.

Conclusion

SatLayer reimagines Bitcoin as a programmable security backbone for decentralized systems, merging its store-of-value status with yield-generating utility. By abstracting technical complexity, it aims to attract both BTC holders and dApp developers.

What’s Next? Can SatLayer scale its security framework to onboard thousands of BVS protocols while maintaining Bitcoin’s core principles?
