**Proposal: Add support for TBTC**  
Joint Proposal by @ramaruro and @Estebank

**Summary**

We propose to add TBTC to AAVE for lending and borrowing. TBTC is the first fully decentralized Bitcoin version on Ethereum.

**Details about TBTC**

tBTC is a decentralized, trustless and insured custody system for Bitcoin that creates TBTC Ethereum ERC-20 tokens, with a 1:1 BTC supply peg. Bitcoin holders who want to spend their BTC on Ethereum and DeFi don’t have to trust custodians, aka signers, because signers must deposit a bond higher than the value of the BTC they hold in custody.

The tBTC system is developed by the Keep Network.

**Benefits for AAVE**  
_TVL Growth_: Bitcoin on Ethereum is a fast growing category of Assets. Bitcoin has an enormous amount of value and it is important to attract that volume to AAVE and DeFi in general.

_Risk Mitigation:_ TBTC is decentralized and does not have a central point of failure like renBTC or WBTC. Its addition reduces systemic Risk. It supports Point 3 of the AAVE Risk Framework evaluation for adding an Asset (which talks about the risk that centralized assets bring to the AAVE protocol).

**Benefits for the general DeFi Community**

Bring Optionality to the DeFi Community with a decentralized Bitcoin Exposure.

Decentralized Assets are essential for DeFi to stay “Decentralized”. It is very important to keep that prospective in mind as a lot of liquidity based on Centralized Assets has flown into the DeFi Ecosystem.

**Current Liquidity and Availability**

_TBTC Contract:_ ([https://etherscan.io/address/0x8daebade922df735c38c80c7ebd708af50815faa](https://etherscan.io/address/0x8daebade922df735c38c80c7ebd708af50815faa))
