SECTION 2a: Team and Product Information

Provide details on your team’s past and current experience. Any details relating to past projects, recent achievements and any past experience utilizing incentives. Additionally, please provide further details on the state of your product, audience segments, and how you expect incentives to impact the product’s long-term growth and sustainability.

Connext was born in 2017 with the vision to help scale Ethereum.

Starting with v1, where the product was based on a simple asset bridge between the user and a router that provided liquidity in the supported chains.

Then, with the arrival of Amarok (v2) the bridge adopted a modular architecture, built on top of the canonical bridges of each domain, acquiring the ability to send both assets and messaging in a trustless way. This opened the door to the creation of cross-chain applications ( xApps).

Today, Connext works as an advanced intent protocol: routers (key players in the network) front cash on the chain where users want to bring funds, and then wait for a refund coming from the underlying protocol, which uses the native bridges of the L2s for optimal security.

On the destination chain (Arbitrum), an AMM pool automatically swaps into canonical ETH (ex: Arb ETH) so that users always receive ETH usable in the Arbitrum ecosystem.
Importantly, this stableswap AMM is extremely capital efficient, and its balance gets skewed in one direction when users bridge into Arbitrum, and in the other direction when ETH is Restaked from Arbitrum. The two flows tend to self balance themselves, and this pilot should help us to identify the best way to keep the pool balanced.

In addition to new updates to our interoperability network, (such as Bacco, which incorporates an optimistic messaging layer in addition to our canonical bridge network) we have focused on providing tools for builders to improve the interoperability experience:

  • xERC20, an open standard, which gives sovereignty back to token issuers over their assets. This standard allows 1:1 transfers between different domains, without requiring liquidity pools, being able to opt for 1 or more bridges, and also the possibility of setting daily/per transaction limits for each of them.

  • Chain Abstraction Toolkit, a set of utilities that simplifies the process of transforming an existing dApp into a xApp, allowing DeFi applications to send messaging/directives to/from different domains, providing the user with a chain-agnostic experience.

What novelty or innovation does your product bring to Arbitrum?

As I mentioned above, thanks to both xERC20 and our crosschain primitives, applications like Renzo Protocol can allow the user to restake their native ETH on Arbitrum without dealing with unreachable gas fees on Mainnet.
Our goal is for Arbitrum to become the primary choice of ETH restakers.

More info on the Restake from Arbitrum module.

Is your project composable with other projects on Arbitrum? If so, please explain:

Yes - Any dApp or DAO on Arbitrum can use Connext to enable a chain abstracted experience for their users: without the need for the app to ever deploy outside of Arbitrum, users can interact with it (deposit, swap, …) even if their funds an initially on another chain - without the user having to explicitly bridge, buy gas, switch their RPCs in their wallets, …
This unlocks an inflow of value from any other chain into Arbitrum, and enables a true chain abstracted experience.

Do you have any comparable protocols within the Arbitrum ecosystem or other blockchains?

Other cross-chain protocols obviously exist and connect with Arbitrum.
Connext is the only generalized trust-minimized cross-chain intent protocol.

How do you measure and think about retention internally? (metrics, target KPIs)

Retention of integrated apps: dApps that integrate Connext are the largest volume generators and are our long-term partners, as they integrate our infrastructure (xERC20, Chain Abstraction, etc.) into their operations.
Those produce further Internal KPIs:

  • volume generated by the dApps that integrated Connext,
  • number of recurring users using cross-chain functionalities.

Relevant usage metrics:

Protocol volume since launchì: $2B+ USD

Protocol volume last 30d: 150.000.000 USD

Protocol volume on Arbitrum last 30d: 40.000.000 USD (26%)

Protocol txns last 30d: 65.000

Protocol txns on Arbitrum last 30d: 20.000

Do you agree to remove team-controlled wallets from all milestone metrics AND exclude team-controlled wallets from any incentives included in your plan: Yes

Detail the requested grant size, provide an overview of the budget breakdown, specify the funding and contract addresses, and describe any matching funds if relevant.

Requested Grant Size: 540k ARB

Justification for the size of the grant 11:

Our recent scaling of the ETH Restaking Module has been limited by the amount of liquidity we currently hold on Arbitrum
Once enough liquidity is bootstrapped, the organic yield that the system generates should be enough to incentivize liquidity stickiness, so we would like to kickstart some incentives to get to that stage.

For this pilot program, we want to run some experiments to create the best user experience for users that want to bridge to Arbitrum and restake their ETH from there.
The questions we want to answer (and measure results for) are:

  • If we bootstrap enough liquidity on the Arbitrum AMM, can we support bigger transfer sizes? How is the volume affected
  • If we bootstrap enough liquidity for routers, does the capital utilization (and therefore their return change)? Are we able to provide the ideal fast, cheap experience for all users?
  • Does incentivizing bridging into Arbitrum via a bridge refund encourage more users to Restake from Arbitrum? Does it help with properly rebalancing our pools?
  • How much new ETH is restaked where all these results are achieved?

To do so we want to incentivize 3 activities:

  1. LPing on Connext ETH pool.
    Value we want to attract in ETH pools: $8m in ETH
    APY needed to be offered on ETH - Based on conversations with LPs: 20%

8*0.20/4 (duration of LTIPP) = $400k

  1. Additional liquidity for Routers on the Arbitrum & Ethereum routes.

Value we want to attract: $4m in ETH

APY needed to be offered on ETH - Based on conversations with institutional LPs: 20%

As a further experiment, routers will be required to commit to locking liquidity for 6 months - even if the distribution of ARB will happen within the agreed 3 months of the program. We want to understand if locking liquidity is a sustainable option for routers, and how their liquidity stays within the system after that.

4 * 0.20 / 2 = $400k

Having deep liquidity will allow us to onboard new LRTs: LRTs embracing the xERC20 standard and the Restake from Arbitrum module will tend to create great ecosystems around them, and work with partners like money markets, yield farming tools, etc.

Committed long term liquidity allows us to guarantee the best user experience to users and dapps, making sure that transactions are fast and seamless when onboarding to and operating on Arbitrum.

We can enable Arbitrum to be the liquidity hub among L2s.

  1. Refund part of the bridging fees for users that bridge into Arbitrum.

Expected volume in ETH during the program (according to last 7 days estimate): 137k ETH
Bridge fees to be refunded: 3bps
Total refund: $145k

Grant Breakdown:

  • $400k: liquidity incentives on top of the Connext AMM pools for ETH on Arbitrum.
    Benefits: enable slow slippage on transactions (both inflow into Arbitrum and Native Restaking flow)

  • $400k: liquidity incentives to routers (active liquidity providers). Benefits: enables fast transactions into Arbitrum from any other chain. This is key as users bring in their ETH to restake it on Arbitrum, and they will only do it if they receive the best experience. A new thriving economy for Arbitrum can emerge.

  • $145k: refund bridging fees to users that bridge their ETH to Arbitrum.
    Incentivizing users on this particular route has 2 benefits:
    We can help more users bridge away from mainnet fees, onboarding them permanently onto Arbitrum
    It helps to rebalance the AMM pool, as the restaking activity tends to unbalance the pool in the opposite direction. Having a balanced pool means that users restaking ETH don’t incur into negative price impact.

Objectives: [Clearly state the primary objectives of the grant and what you intend to achieve]

  • Make Arbitrum the home of LRTs
  • Have value flow into Arbitrum for the long term
  • Enable smooth ETH-centric applications on Arbitrum

Execution Strategy:

Execution Strategy:

  • We have a staking smart contract that is being audited and will be deployed on Arbitrum.
  • Users who stake their LP tokens will be eligible to claim ARB tokens.
  • Users who bridge into Arbitrum will be able to claim their ARB tokens to refund part of the bridging fee
  • Offchain agreements with routers will be signed to lock their liquidity for 6 months.
    As the network doesn’t technically allow for any liquidity lockup, only routers that have completed a KYB with Connext will be eligible for this type of agreement.
    The ARB tokens will be disbursed and the addresses of the beneficiaries included in our reports (highlighting the liquidity locked).

Explainer on Routers: Routers are off-chain agents that are part of the Connext protocol.
They help to speed up the transactions of the network: Their function is to observe the events that originate in Connext contracts (a user initiating a bridge) and, based on this, front the funds to the user on the destination chain.

Liquidity with routers means that fast transactions can be executed into Arbitrum, enabling the smoothest user experience possible.

To ensure that the new liquidity provided by the routers will remain in Arbitrum and given their nature of off-chain agents, off-chain agreements will be put in place to lock in the capital for a minimum of 6 months.

What mechanisms within the incentive design will you implement to incentivize “stickiness” whether it be users, liquidity or some other targeted metric? [Provide relevant design and implementation details]

  • Routers will be obliged to sign a 6 months capital lock.
  • LRTs tend to stick within the ecosystem they are created when there are interesting opportunities to use them

Specify the KPIs that will be used to measure success in achieving the grant objectives and designate a source of truth for governance to use to verify accuracy.

  • ETH attracted on Connext AMM Pools: min $5m, target $8m
  • ETH committed by routers: $4m
  • ETH Natively Restaked via partners: min $5m, target $20m

Grant Timeline and Milestones:

Timeline: starting in April, the incentives will run for 12 weeks.

  • ETH Pools show APY based on Arbitrum rewards
  • ARB being able to be claimed for LP stakers

Starting in April, the incentives will begin to be distributed linearly over three months, both to LPs and Router Liquidity Providers.

In the case of Routers, the amount allocated to each will depend on the capital they commit to contribute and guarantees them 20% APY for the time they commit to lock.

Formula: Capital x 0.2 (APY) x time locked.

Users will instead be able to claim their ARB refund directly after the bridging activity, up until the allocated pool is emptied, or the program is concluded.

Expected milestones

Month 0: $4M Router Deposits ($400k of ARB to be linearly distributed through the program)

Month 1: $4M LP deposits ($66k of ARB distributed). 44k ETH bridged into Arbitrum ($50k of ARB distributed)

Month 3: $8M LP deposits ($400k of ARB distributed) 137k ETH bridged into Arbitrum ($150k of ARB distributed)

How will receiving a grant enable you to foster growth or innovation within the Arbitrum ecosystem?

Our Native Restaking from Arbitrum module can enable all Liquid Restaking Providers to easily bring their LRTs to Arbitrum, and at the same time enable users to send ETH and receive the LRT directly on Arbitrum - without ever leaving the L2.

Restaking is a big threat and a big opportunity for Arbitrum.
By design, ETH and LSTs tend to flow out of Arbitrum to be restaked on mainnet.
But, thanks to Connext innovation, these LRTs can actually flow back to Arbitrum (or better: be minted directly on the rollup) so that:

  • Value stays on the L2
  • LRTs can be used in Defi to amplify the Arbitrum economy

Let’s be clear: all L2s are starting to look at this opportunity in what will soon become a gold rush. By making sure LRTs are encouraged to deploy on Arbitrum via high liquidity and the secure, mainnet-abstracted flow that Connext provides, Arbitrum can retain its advantage among L2s.

The xERC20 standard enables LRT issuers to move their tokens without any vendor lock up via any 3rd party bridge or even the native bridge of Arbitrum.

Do you accept the funding of your grant streamed linearly for the duration of your grant proposal, and that the multisig holds the power to halt your stream? Yes

SECTION 5: Data and Reporting

OpenBlock Labs has developed a comprehensive data and reporting checklist for tracking essential metrics across participating protocols. Teams must adhere to the specifications outlined in the provided link here: Onboarding Checklist from OBL 5. Along with this list, please answer the following:

Is your team prepared to comply with OBL’s data requirements for the entire life of the program and three months following and then handoff to the Arbitrum DAO? Are there any special requests/considerations that should be considered? Yes - No special requests

Does your team agree to provide bi-weekly program updates on the Arbitrum Forum thread that reference your OBL dashboard?

Yes. We have our explorer https://connextscan.io that will be used to report metrics

First Offense: *In the event that a project does not provide a bi-weekly update, they will be reminded by an involved party (council, advisor, or program manager). Upon this reminder, the project is given 72 hours to complete the requirement or their funding will be halted.

Second Offense: Discussion with an involved party (advisor, pm, council member) that will lead to understanding if funds should keep flowing or not.

Third Offense: Funding is halted permanently

Does your team agree to provide a final closeout report not later than two weeks from the ending date of your program? This report should include summaries of work completed, final cost structure, whether any funds were returned, and any lessons the grantee feels came out of this grant. Where applicable, be sure to include final estimates of acquisition costs of any users, developers, or assets onboarded to Arbitrum chains. (NOTE: No future grants from this program can be given until a closeout report is provided.)


Does your team acknowledge that failure to comply with any of the above requests can result in the halting of the program’s funding stream?:

As I was asked to clarify this, the requested amount is

540,000 ARB

At the current ARB price ($1.75) that’s equivalent to $945,000 USD.

The budget has been broken down into the different areas and milestones.



following the rejection of the initial proposal from the LTIPP Council, this week we’ll be re-submitting it on Snapshot with a few modifications. The council feedback could be summarized as:

  • Incentives should go more towards users
  • Lack of benchmarking with other bridging projects to justify LP requests

I believe in general there is a misunderstanding of Connext: we don’t aim to be a user-facing bridge;
our main users are apps, and we serve them and their users.

As a result, we brought more than $285m of LRTs to Arbitrum in the last 3 months, and more than $280m went through Arbitrum in the last 30 days alone.

We want Arbitrum to succeed, and our priority remains to attract more users to bridge into Arbitrum and Restake ETH on the L2.

The most straightforward way for us to do that would be to incentivize the liquidity in our pools (more liquidity = better pricing for apps we offer our Restaking service to), but, as the Council required to move the incentives toward users, we can switch the point of view:

In order to provide the best experience, we can incentivize users by subsidizing part of the bridging fees, and this will further boost the utilization of our pools which will increase our ETH TVL. Higher TVL enables us to provide the best pricing when the Restaking module is used.

Incentivizing users to bridge into Arbitrum has 2 benefits:

  1. We can help more users bridge away from mainnet fees, onboarding them permanently onto Arbitrum
  2. It helps to rebalance the AMM pool, as the restaking activity tends to unbalance the pool in the opposite direction. Having a balanced pool means that users restaking ETH don’t incur a negative price impact.

Therefore, we decided to:

  • Remove the request of liquidity incentivization for our routers and LPs, and shift focus towards our users
  • Refund 95% of the fees to the users bridging into Arbitrum, up to 13bps. Fees vary depending on the origin chain (from mainnet it’s 9bps, from other L2s, 13bps) so only the actual fees incurred will be refunded.
    Gas fees will only be subsidized to users who are onboarding to Arbitrum (from any other network), and users exiting Arbitrum will not get subsidized.

Our estimate (according to the average of the last 7 days at the time of writing the original proposal) is for users to bridge 137k ETH during the pilot program.

Bridging fee rebate: 137,000 * 0.0013 (max fee) * 0.95 = 169 ETH

Tot ask: 446,472 ARB (1 ETH = 2,646.75 ARB at the time of writing)

Note: pricing the ask in ARB vs ETH as the pair is less volatile, thanks @pedrob for the suggestion.

Expected milestones

Month 1: 45k ETH bridged into Arbitrum (30% of ARB distributed)

Month 2: 90k ETH bridged (60% of ARB)

Month 3: 137k ETH bridged ($100% of ARB)

The Connext team agrees to return to the Arbitrum DAO any unused ARB funds once the 12 week LTIPP program is concluded


We will vote in favor of this proposal at the snapshot stage. We have taken into account the current 30-day trading volume and are confident that the fee subsidization will provide a compelling incentive for the Connext user base to bridge to Arbitrum.

Following the Council’s recommendation, Connext modified the distribution mechanism by focusing incentives on covering the gas costs for bridging, specifically targeting 100% of users coming from other networks to Arbitrum. Moreover, it estimates this cost based on user activity seven days before submitting the original proposal.

Following @pedrob recommendation, they estimated the cost of bridging in ETH rather than in USD.

Considering that they addressed the Council’s concerns, we are voting in favor of this proposal.

Thank you for the updated proposal. Connext’s focus on user incentives reflects a better approach. By subsidizing bridging fees, they aim to attract more users to Arbitrum and provide a balanced AMM pool. We appreciate the clear milestones, and overall, we support this proposal as ITU Blockchain.
