SatsFlux Token Staking
Stake SatsFlux tokens to participate in network security and earn rewards from bridge fees
How SatsFlux Staking Works
Network Security
Staked SatsFlux tokens secure the bridge protocol by bonding signers who collectively control the Bitcoin vault.
Fee Rewards
Earn rewards from bridge fees distributed proportionally to your staked SatsFlux tokens. Higher stake, higher rewards.
Slashing Protection
Economic security model ensures signers behave honestly or face slashing penalties, protecting the network integrity.
Flexible Staking
Choose your staking duration and participate in governance decisions while earning rewards from protocol fees.
Example: "Stake 1M SatsFlux Tokens"
1
Stake Tokens
Lock your SatsFlux tokens in the staking contract to participate in network security and governance
2
Earn Rewards
Receive proportional share of bridge fees distributed weekly to all staked token holders
3
Participate in Governance
Vote on protocol parameters, new chain integrations, and signer set management decisions
Important Risk Information
SatsFlux staking involves smart contract risks, protocol failures, and potential loss of funds. SatsFlux does not guarantee returns or protect against losses. All staking carries risk including but not limited to: protocol hacks, governance attacks, liquidity crises, and market volatility. Only stake funds you can afford to lose. Past performance does not indicate future results.
Security & Trust Model
Cryptographic security meets economic incentives. SatsFlux eliminates single points of failure through threshold signatures and signer bonding.
Comprehensive Risk Assessment & Mitigation Strategies
Threshold Cryptography
Bitcoin vault secured by MuSig2 and FROST threshold signatures. No single party can access funds - requires cooperation from multiple signers.
Economic Security Model
Signers stake SatsFlux tokens as collateral and can be slashed for misbehavior. Economic incentives align with protocol security.
Taproot Integration
Leverages Bitcoin's latest privacy and efficiency improvements with Schnorr signatures for enhanced security and reduced on-chain footprint.
Multi-Layer Verification
Smart contracts verify threshold signatures and Bitcoin proofs before minting sBTC. Emergency circuit breakers for additional protection.
Risk Disclosure
Cross-chain bridging involves inherent risks including smart contract vulnerabilities, bridge failures, signer collusion, and potential loss of funds. While SatsFlux employs multiple security layers including threshold cryptography and economic bonding, no system is completely risk-free. Bitcoin bridging carries additional risks from Bitcoin network congestion and confirmation delays. SatsFlux does not guarantee the safety of funds or successful bridge operations. Only bridge amounts you can afford to lose.

Frequently Asked Questions
Everything you need to know about SatsFlux's Bitcoin bridging protocol
What is SatsFlux and how does it work?
SatsFlux is a decentralized Bitcoin bridge protocol that enables BTC to flow across multiple blockchain networks. Users deposit BTC into a secure vault controlled by threshold signatures, and receive sBTC tokens on their chosen chain (Ethereum, Arbitrum, Base, Solana, etc.). sBTC is fully backed 1:1 by Bitcoin held in the vault.
How secure is the Bitcoin vault?
The Bitcoin vault uses Taproot-enabled threshold signatures with MuSig2 and FROST cryptography. A decentralized network of signers collectively controls the vault - no single party can access the funds. Signers must stake SATS tokens as collateral and can be slashed for misbehavior, ensuring strong economic security.
What is sBTC and how is it backed?
sBTC is a 1:1 Bitcoin-backed token that can exist on multiple chains simultaneously. Every sBTC token is fully collateralized by real Bitcoin held in the SatsFlux vault. You can mint sBTC by depositing BTC, or burn sBTC to redeem native Bitcoin back to your Bitcoin address.
How do threshold signatures work?
Threshold signatures allow multiple signers to collectively control the Bitcoin vault without any single point of failure. Using advanced cryptography (MuSig2/FROST), transactions require cooperation from a threshold of signers (e.g., 15 of 21). This eliminates custodial risk while maintaining security and liveness.
Is SatsFlux custodial? Who controls my Bitcoin?
SatsFlux is non-custodial and trust-minimized. Your Bitcoin is held in a decentralized vault controlled by threshold cryptography - no single entity can access the funds. The signer network is economically bonded through SatsFlux token staking and operates under cryptographic and economic security guarantees.
What chains and networks are supported?
SatsFlux supports Ethereum, Arbitrum, Base, Solana, and plans to expand to additional networks. sBTC can be minted on any supported chain, and our multi-chain routing layer enables efficient movement between chains via burn-and-remint or direct Bitcoin redemption.
What are the fees and how does SatsFlux token work?
Bridge fees are approximately 0.20% of transaction value. SatsFlux token holders can stake to become signers and earn fee rewards. SatsFlux also provides governance rights for protocol parameters, new chain integrations, and signer set management. Total supply is 500 billion tokens.
