Proposed by the Badger DAO. This is a proposal to add ibBTC+crvRenWSBTC factory pool to the Gauge Controller. This will allow users to assign gauge weight and mint CRV.
The factory pool is live with $280k+ of liquidity.

Adding an ibBTC pool will further increase the liquidity of Bitcoin on Ethereum and make it easier to swap between assets.
Hello everyone, my name is Spadaboom, a contributor at Badger DAO and proponent of ibBTC. The intention for this post is to (1) introduce ibBTC to the Curve community, and (2) provide subsequent information to inform voters for adding the ibBTC+crvRenWSBTC factory pool to the Gauge Controller.
ibBTC is an asset launched in collaboration with DeFiDollar, it stands for Interest Bearing Bitcoin. It was created to serve as the default interest-bearing Bitcoin asset across DeFi.
ibBTC is an ERC-20 token. As such it can be transferred normally, lent out, collateralized and bridged to other chains with the goal of enabling people with the most basic DeFi knowledge to start earning interest in just a few clicks.
Current market cap of ibBTC is $40M with $50M+ in liquidity across mainnet, Polygon and Solana. https://www.coingecko.com/en/coins/interest-bearing-bitcoin#markets
ibBTC is backed 1:1 by a basket of our Badger vault tokens which themselves are interest maximizing products accepting deposits of different synthetic BTC’s with a focus on CRV LP’s. Each runs a different underlying smart contract based strategy. Users can mint ibBTC in the Badger App with these 4 vault positions;

The underlying APY for ibBTC is the average APY for the composition of vault tokens in its basket.
As of writing this proposal the current composition of ibBTC is;

Recent snapshot of the 24 hour underlying APY of ibBTC:
Badger DAO recently rebalanced the composition of collateral assets to optimize underlying APY for ibBTC and minimize risk of the underlying synthetic BTC’s that make up its basket. The community governed Badger council reviews and approves rebalancing proposals prior to execution. Moving forward we plan to rebalance on a recurring basis.
Through our recent rebalance we’ve been able to increase yield for ibBTC along with reducing underlying risk of certain synthetic BTC’s.
As part of rebalancing we will have a criteria for adding new vaults to the ibBTC basket. We anticipate additional Curve/Convex optimizer vaults to be incorporated as only 3 of 8 are currently included.
How the underlying strategies of ibBTC work
Curve/Convex Optimizer Vault Strategies
Badger DAO is dedicated to having a “partner first” approach to our vaults and how they create yield for our users. The intention of our strategies are to give optimized yield while supporting the protocols that the yield comes from.
With that in mind, 3 of the 4 underlying vault tokens (CRV ren, sbtc and tbtc lp’s) that make up ibBTC have Curve/Convex optimizer strategies. Where 80% of all earned yield in the form of CRV or CVX is either held as veCRV (through Convex cvxCRV) or staked via CVX pool.
Here is a breakdown on how the bCrvRenWBTC, bCrvRenWSBTC and bCrvtBTC strategies work. After locking CRV via cvxCRV we are taking the rewards earned (CVX, CRV, 3CRV) and buying cvxCRV on the market to further support its peg and lock up even more CRV.
With about $295M in TVL deposited in Curve/Convex through these specific vaults, our vaults are projected to lock a significant amount of Curve annually while bringing additional utility and rewards to CRV LP’s through trading fees (vault harvests) and additional Badger rewards.
Per the current emissions schedule, these 3 vaults have received 57k Badger token rewards over the last 5 weeks. Historically have distributed 2.4M Badger tokens (11.5% of supply) to vault depositors.
New Badger ibBTC Curve/Convex Optimizer Vault
As of writing this proposal roughly 26% of BTC CRV LP tokens are deposited in the Badger app utilizing our Curve/Convex optimizer strategies.
To further optimize the CRV rewards allocated to this pool if it were to be added to the gauge controller, Badger will build an ibBTC CRV LP vault in our app. Where users can deposit the LP tokens from this ibBTC+crvRenWSBTC factory pool.
It will leverage a similar Curve/Convex optimizer strategy to our other vaults but it will sell NO CRV or CVX but only lock and stake them. This is a further dedication to supporting Curve/Convex and ensuring there are no “double dipping” concerns from the community as all rewards going to this pool won’t be sold.
We will advocate for the vault to receive similar Badger rewards and APY to the max boost level of the existing crvrenBTC vault at present TVL. Ideally this will help drive significant liquidity to this pool fairly quickly.
Assuming that a large majority of the ibBTC LP tokens that would be receiving CRV gauge rewards will be deposited into the Badger app (based on historical deposits), 100% of these rewards would be locked as veCRV (via Convex cvxCRV).
10% of ibBTC is made up of the Yearn WBTC vault that lives in the Badger app (byvWBTC).
This vault deploys a variety of strategies illustrated below.
54% of the BTC in this vault is deployed to strategies that sell CRV rewards.
This has little impact on ibBTC “double dipping” as that vault makes up only 10% of ibBTC and the remaining 90% of which are vault strategies that support both Curve and Convex through staking/locking.
54% x 10% = 5.4% of CRV selling that ibBTC does through this vault.
Addressing Double Dipping Concerns
There has been some scrutiny of assets being listed on Curve that receive CRV rewards and in turn create sell pressure on the native CRV asset.
Badger is ecosystem focused and deploys vaults to strategies that don’t just dump the underlying reward assets. For example, Badger’s Sushiswap LP vaults have staked Sushi rewards from day one.
The increased TVL and liquidity benefits of bringing new vault strategies to Curve and Convex far outweigh the 20% of rewards that are sold by the strategies to produce yield in the underlying deposited assets.
On top of this the new ibBTC CRV vault mentioned above would only lock rewards distributed to this pool and not sell any.
90% of CRV is locked for 4 years, we stake 80% of CVX which further supports Curve, and the CRV rewards for the potential new ibBTC CRV pool vault when launched will also lock 100% of rewards.
See a breakdown of how CRV rewards are leveraged through our vaults below.
Assuming Baseline APY of 3.33% in CRV rewards
Assuming TVL of $300M on CRV LP that are deposited in underlying vault tokens that make up the ibBTC basket
$$ value of CRV sold over 1 year = $2M ($167k/month)
$$ value of CRV locked over 1 year via Underlying vault tokens = $8M ($667k/month)
$$ value of CRV locked over 1 year via ibBTC CRV LP vault on Badger (assuming an additional $300M pool TVL) = $10M ($833k/month)
If ibBTC were to be approved for a Curve pool with full rewards and assuming the TVL number above ($300M in underlying vault tokens and $300M in new ibBTC pool) then:
$18M of CRV per year would be locked for 4 years with just $2M in CRV being sold annually; 9:1 benefiting CRV holders as locking takes assets off the market that might otherwise be sold and coordinate incentives for long term participants of which Badger is one. This doesn’t account for additional fees earned by veCRV holders since all these swaps would happen on Curve.
Coupled with that, our vaults would be staking the equivalent amount ($18M) in CVX. Actively helping keep the peg of cvxCRV through buy pressure, improving the utility of the cvxCRV asset, and ultimately furthering the relationships and synergies between our three protocols.
Voting for full rewards to the pool would signal to BadgerDAO that the Curve community supports our mission of being ecosystem friendly, and would further enable our protocols to continue building incredible things together. We hope the promise of locking 100% of the rewards sufficiently communicates our intent to support such an important DeFi player as Curve.
With Curve’s cross-chain expansion to Polygon, FTM, xdai and other chains/L2’s as they launch, ibBTC is an ideal asset for subsequent BTC pools on those chains. As Curve looks to continue expanding, it’s important to have transferable assets with a track record on their ETH mainnet market.
Currently ibBTC lives on ETH, Polygon and Solana with the intention to expand to Arbitrum, Optimism, Fantom, xDAI, Avalanche and many others.
With over $30M+ of liquidity across Solana and Polygon, it shows the potential for ibBTC pools on Curve’s cross-chain markets in the future.

Badger Bridge is a first of its kind bridge that allows users to go directly from native BTC to earning yield on mainnet tokenized Bitcoin immediately, all while transacting within the same app through the Mint and Earn functionality.
With the bridge’s Mint and Earn feature users experience a 1-step process to transform native BTC into Badger Curve setts (bCrvRenWBTC, bCrvRenWSBTC and bCrvtBTC).
The bridge is also utilized to convert native BTC to wBTC. To achieve this BTC is converted to renBTC and renBTC swapped to wBTC via Curve BTC pools.
To date net in-flows of native BTC crossing the bridge to mainnet exceeds $135M (3,000 BTC). Roughly $95M (2,100+ wBTC) have been swapped in curve pools by users crossing the bridge with native BTC.
The Badger Bridge has been operational for a few months and remains a key element in fulfilling our mission to bring Bitcoin to DeFi, its utility will continue to grow with the inclusion of one click ibBTC and ibBTC LP minting.

Compared with other AMM-based DEXs, Curve’s stablecoin/like kind pair swapping curve has lower transaction slippage. Adding ibBTC to a metapool will increase liquidity and utility for the asset. Our hope is that this pool will create a positive flywheel and help bring more fees and incentives to the Curve protocol.
Curve’s importance in the defi ecosystem is not to be taken lightly and BadgerDAO wants to continue to foster a positive relationship that can benefit both users of each protocol as well as the broader ecosystem through more capital efficient swapping and increased liquidity.
