Endur Introduces BTC liquid staking
Starknet has launches BTC staking and Endur is ready with liquid staking on all 4 BTC assets supported by Starknet to push liquid-staking of BTC.
Introduction
For most of its history, Bitcoin has been a passive store of value. While Ethereum and other Proof-of-Stake networks enabled yield generation through staking, Bitcoin remained largely non-productive capital, held in custody or used sparingly in centralized lending markets.
That paradigm is now shifting.
With the emergence of BTCFi (Bitcoin DeFi) and execution environments like Starknet, Bitcoin is becoming a fully composable on-chain asset capable of generating yield, participating in DeFi markets, and maintaining liquidity.
Starknet now enables Bitcoin staking at the protocol level, allowing BTC to contribute to network security while earning rewards. Building on this foundation, Endur introduces liquid staking for Bitcoin, unlocking a new primitive:
Bitcoin that earns yield while remaining liquid and deployable across DeFi.
This is not an incentive-driven narrative. It is a structural shift toward making Bitcoin a productive financial asset within decentralized systems.
Supported BTC Assets on Starknet
Endur enables liquid staking across the major BTC representations available on Starknet:
WBTC → xWBTC
tBTC → xtBTC
LBTC → xLBTC
solvBTC → xsBTC
These assets represent different bridging and custody models for Bitcoin entering DeFi. Learn more about Bitcoin wrappers and their trust assumptions in our guide.
What is xyBTC?
xyBTC refers to Endur’s family of Bitcoin Liquid Staking Tokens (LSTs).
x → Endur prefix
y → underlying BTC variant
Examples:
xWBTC
xtBTC
xLBTC
xsBTC
These tokens represent a yield-bearing claim on staked Bitcoin, where:
The share count remains constant
The value of each token increases over time
This follows the same exchange-rate model used in liquid staking systems like Ethereum LSTs, but adapted for BTCFi.
How Bitcoin Liquid Staking Works
Step-by-step flow
Deposit BTC (WBTC, tBTC, LBTC, solvBTC) into Endur
Receive corresponding LST (xWBTC, xtBTC, etc.)
BTC is delegated to Starknet’s staking layer
Rewards are generated in STRK
Rewards are auto-compounded into BTC denomination
LST exchange rate increases over time
Yield Mechanics
Starknet’s security model now includes BTC as a staking asset, with a growing portion of network security backed by Bitcoin.
Rewards are emitted in STRK
Endur automatically converts rewards into the underlying BTC asset
Yield is reflected through LST appreciation, not token distribution
This creates a clean abstraction:
Users hold BTC-denominated assets while earning yield from network participation.
Liquidity Layer: Why Liquid Staking Matters
Traditional staking introduces lockups and illiquidity.
Endur removes this constraint.
With liquid staking:
Your BTC remains fully transferable
Your position remains DeFi composable
Your yield accrues passively via exchange rate
This enables a new class of BTCFi strategies:
DeFi Composability on Starknet
Once minted, BTC LSTs can be deployed across Starknet’s DeFi ecosystem:
Lending & Borrowing
Use LSTs as collateral on:
Vesu
Opus
Borrow stablecoins while maintaining BTC exposure.
Liquidity Provision
Provide liquidity on AMMs such as:
Ekubo
AVNU
Earn trading fees on top of staking yield.
Automated Yield Strategies
Deploy capital into vault strategies via:
- Troves
Auto-compound yield across LPs and lending markets.
Exit & Redemption Mechanics
Endur supports multiple exit paths:
1. Standard Unstaking
Unbonding period: ~7–8 days
Reflects underlying staking mechanics
2. Secondary Market Liquidity
LSTs can be traded instantly via:
Ekubo
AVNU
This enables immediate exit without waiting for unstaking.
3. Deposit–Withdrawal Matching
Endur implements a matching engine:
New deposits offset withdrawal requests
Enables faster redemptions
Zero slippage during matching
This creates a liquidity buffer layer on top of staking.
Security & Infrastructure
Security is foundational to BTCFi adoption.
Endur smart contracts are audited and production-tested
Built on Starknet’s zk-rollup architecture, ensuring: cryptographic validity proofs, scalable execution, secure settlement
Key benefits:
Need faster exits?
Trade your LSTs instantly on Ekubo or Avnu DEXs, using actual LST liquidity on AMM.
Deposit-withdrawal matching lets Endur users redeem faster, with zero slippage during matching events. This is subject to liquidity availability which is dependent on new deposits. In any case, worst case unstaking time is 7-8 days. Learn more.
