# Endur

> The Most Trusted BTC & STRK Liquid Staking Protocol on Starknet

Endur is a liquid staking platform on Starknet that lets users stake STRK and BTC-backed tokens to earn staking rewards while keeping assets liquid.

Endur enables users to stake STRK or multiple BTC-backed tokens on Starknet and receive liquid staking tokens in return. Users can deploy these LSTs as collateral in lending markets, trade them on decentralized exchanges, and access other DeFi applications while continuing to earn staking rewards. The protocol charges no fees on staking or redemption and supports faster withdrawals than the native unstaking period.

## Products

- [Endur](https://thegrid.id/profiles/endur_fi): Endur is a liquid staking protocol on Starknet that issues yield-bearing LSTs for staked STRK and BTC-backed assets. Users deposit STRK or supported BTC variants to receive xSTRK or corresponding BTC LSTs, which auto-accrue rewards and remain usable as collateral across Starknet DeFi protocols. Staking and redemption carry no protocol fees, and withdrawals settle faster than the native unstaking period via a deposit-withdrawal matching system. (Liquid Staking, Live, Main Product)
