WBTC 101: What is Wrapped Bitcoin?
If you're new to crypto and curious about WBTC, this thread breaks down what it is, why it exists, and how it helps you do more with your Bitcoin.🧵

1/ WBTC is Bitcoin but multichain.
Wrapped Bitcoin (WBTC) is a token that represents Bitcoin, but lives on Ethereum, Solana and other smart contract networks.
For every 1 WBTC, there is 1 real BTC held in reserve by a custodian.
It’s fully backed, transparent, and redeemable.
2/ Why wrap Bitcoin in the first place?
Bitcoin doesn’t work with smart contracts or DeFi apps.
WBTC was created to give Bitcoin the ability to move and interact inside Ethereum’s ecosystem.
3/ What can you do with WBTC?
Once you’ve got WBTC, your Bitcoin becomes usable in DeFi. You can:
- Lend it and earn interest
- Use it as collateral to borrow other assets
- Provide liquidity in pools
- Join strategies like yield farming or staking
4/ Key benefits of WBTC:
It’s always backed 1:1 by real Bitcoin
It works seamlessly with smart contracts, protocols and apps
It has faster transaction speeds than native Bitcoin (1-15 seconds vs 10+ minutes)
TL;DR/ WBTC makes your Bitcoin usable.
Instead of just holding BTC in cold storage, you can put it to work across DeFi protocols, while still keeping exposure to Bitcoin.
