tBTC is a decentralized wrapped Bitcoin, that is 1:1 backed by mainnet BTC.
Unlike other wrapped Bitcoins, the BTC that backs tBTC is not held by a central intermediary, but is instead held by a decentralized network of nodes using threshold cryptography. tBTC is trust minimised and redeemable for mainnet BTC without a centralized custodian.
tBTC is built with Threshold Network’s decentralized infrastructure, and Ethereum.
This proposal aims to add a veBAL gauge for the Balancer tBTC/ETH pool on Arbitrum.
Threshold DAO has recently launched a L2 growth campaign with Wormhole, which has enabled a canonical tBTC bridge to Arbitrum.
The DAO has budgeted T token bribes to incentivise this tBTC/ETH pool, with the goal to attract liquidity to the pool and Balancer. Threshold DAO intends tBTC to become a core component of Balancer BTC liquidity on Arbitrum.
These pools are part of the tBTC launch promotion on Arbitrum which will commence next week and feature Balancer as a liquidity target and collaborator. There is currently another proposal in the forum to enable the tBTC/WBTC gauge.
Governance: tBTC operates on Threshold DAO’s decentralized threshold encryption protocol. Threshold DAO is governed by the network’s work token, T. T token holders govern the DAO via proposals raised to the Threshold forum, which can be raised to a vote via Snapshot, as well as the on-chain Governor Bravo module.
Oracles: tBTC does not rely on an oracle price feed.
Centralization vectors: Threshold Network governance is decentralized, and updates are ratified by the DAO via token holder vote. tBTC contract updates are currently managed by the Council multi-sig, with plans to migrate control to the DAO once cross-chain deployment is complete.
Market History: tBTC is a wrapped BTC token, and is pegged to the price of BTC. Since launch, tBTC’s price has not significantly diverged from that of BTC. tBTC launched in January of 2023, and currently has ~700 BTC to collateralize the ~700 tBTC.
Value: The Arbitrum tBTC/ETH will support BTC routing and liquidity on Arbitrum.
Threshold DAO has allocated a portion of its incentives budget to bribe the tBTC/ETH pool using Paladin. This will incentivise veBAL holders to vote on our gauge to direct protocol emissions and attract TVL as part of the tBTC growth strategy on Arbitrum.
Furthermore, Balancer is featuring in the Arbitrum launch promotion that Threshold DAO will commence next week. Lastly, Balancer will benefit by attracting additional BTC liquidity to Arbitrum.
