OP Rewards Impact Analysis: Celer Protocol

Program Information

Key Takeaways

  • In the campaign’s early stage, offering Liquidity Rewards was effective in boosting the Total Value Locked during that time frame.
  • A substantial amount of funding remains unallocated to any program, impacting Celer’s potential to expand within the Optimism ecosystem.
  • Celer employed a strategy to attract USDC, USDT, and ETH by using a capital-efficient approach to incentivize liquidity providers.


Celer has received 1,000,000 OP tokens from the Optimism Governance Fund. Initial funding distribution highlighted in the proposal included 650,000 OP for the Liquidity Mining Program aimed at increasing depth liquidity pools on Celer, 150,000 OP for User Onboarding by Incentivizing early migrants to Optimism with Gas Fee Rebates/Discounts & 200,000 OP for Builder Grants increasing cross chain adaptation along with cBridge Widget Integration.

The grant period mentioned in the proposal suggested six months to one year. Currently, we are past the year benchmark and more than 75% remaining unallotted.

Program Overview

  • Celer has implemented two comprehensive programs known as the Farming Reward Program and the Incentive Event Reward Contract. No details for the Builder Grants Program were found on Celer Forum nor any public updates provided about it.

Farming Reward Contract - 0x06292de88adb3b1557b034ebb1c367e65ab93e4c

The announcement of the program cannot be found but it can be seen on the single side asset supply pool Front End. The reward is provided by boosting the APR for USDC, USDT & ETH. 220,000 OP tokens are allotted till date & the program is still live.

Incentive Event Reward Contract - 0xf6c5d7da1654d9bbde0d25a5fd6776b37a2ad881

The program’s goal was to attract more users to utilize the Celer Protocol, which would mutually benefit Optimism by increasing the inflow of high-value assets.

You can find the announcement of the program on Twitter. Although the blog link in the tweet leads to a “Page not found” error, you can also discover the program’s launch through Binance Feed by Celer.

The end date was determined based on the last transaction associated with the contract address, and it appears to have concluded before distributing the intended 150k $OP tokens.

Around 30,000 $OP tokens were distributed as part of this program.

Total Value Locked

The Total Value Locked (TVL) of the protocol was significantly increased by CELER’s The Farming Reward Event, which began on August 13, 2022, is ongoing. Notably, the greatest increase in TVL occurred between February and May. The event’s ability to draw money and spur exponential growth was highlighted by TVL reaching an astonishing peak of $17 million in April.

The graph covers all the tokens locked on CELER’s cBridge(Optimism). Currently, Celer has ten tokens with five tokens having some liquidity movements.

TVL By Period (FarmingReward Program)

Celer Network’s reward program significantly boosted its Total Value Locked (TVL). At the program’s launch, the network had an average of $6.5 million in value locked. During the program, this figure increased to an average of $7.6 million, showcasing a growing interest in Celer’s ecosystem. Even 30 days after the event’s commencement, Celer Network maintained an average TVL of $7.4 million. Looking ahead to 90 days after the program’s start, Celer Network still maintained a solid average TVL of $6.2 million.

Farming Rewards are live only for USDC, USDT & ETH. The table below illustrates the sum of three tokens for TVL (USDC, USDT, and ETH) on cBridge.

It’s noticeable that there was a significant rise in Total Value Locked (TVL) following the initiation of Farming Rewards, particularly for three high-value tokens. However, the subsequent overall decrease in TVL may be attributed to broader market conditions and Celer’s marketing endeavors aimed at reaching a broader audience.

Daily Transactions

The Fee Rebate Event (IncentiveEvent Reward program), which ran from November 15, 2022, to June 14, 2023, had a substantial impact on both daily transactions on CELER as well as Total Value Locked (TVL), and it also catalyzed TVL. Notably, the event saw a spike in daily transaction volume that outpaced earlier times.

Daily Transacting Addresses

The commencement of the Fee Rebate Event (IncentiveEvent Reward program) marked a significant uptick in daily transacting addresses on CELER. As the event unfolded, a noticeable surge in new users engaging with the platform was observed. This surge predominantly occurred at the event’s onset, indicating the immediate impact of the fee rebate incentives.

Daily Network Fees Generated

According to the graph, it’s evident that on June 1, 2022, the network fees generated were at an all-time high, totaling 0.008760 ETH. As the Fee Rebate event commenced, there wasn’t a significant impact at the program’s outset. However, towards the end of the program, the graph shows a remarkable surge in fees. The peak occurred dramatically on June 1, 2023, surpassing 0.006872 ETH. Celer generated 0.03715477494089086 ETH in network fees throughout the Fee Rebate program.

While this shows direct contribution to Optimism, it shall be the basis to judge the contribution of the protocol. The assets brought on Optimism are eventually going to boost the network fee.

Protocol-Specific Metrics

Inflow and Outflow volume on CELER for USDC,USDT and WETH

During the Fee Rebate Event, starting on 15th Nov 2022, an intriguing pattern emerges in the data. Inflows and outflows show distinct trends for different tokens. For WETH and USDC, the volume surges at the beginning of the event, indicating increased activity right from the start. However, for USDT, the peak in inflow and outflow volume occurs towards the end of the event, suggesting a different behavior pattern. This data showcases the dynamic nature of token movement during the Fee Rebate Event, with different tokens experiencing varying levels of activity at different stages of the event.

Total Inflow Volume (USDC,USDT,WETH) By Period (IncentiveEventReward Program)

The average inflow into the Celer Network experienced a significant surge both during and after the Incentive Event Reward program. Before the program, spanning seven months, the network saw a total inflow of $57.9 million. During the same duration when the program was active, the total inflow showed remarkable growth, reaching $429.6 million, signifying increasing interest and engagement. Following the program, in the subsequent one month, the Celer Network maintained a substantial total inflow of $5.65 million, indicating the sustained value of the ecosystem.

To provide context, in the 90 days leading up to the event’s launch, the network witnessed a total inflow of $11.57 million. In the 90 days following the event’s commencement, this figure surged to an impressive $225.21 million. These statistics highlight the program’s effectiveness in attracting capital, fostering participation, and ultimately enhancing the network’s overall inflow.

While the above analysis was specific to three tokens, the Total Inflow within Celer Network is diversified across a range of tokens, highlighting the network’s versatility and appeal. Among the tokens, USX holds the largest share with an impressive 33.75%, WETH commands a significant portion, constituting 25.09% of the Total Inflow. Thales, with a share of 22.86%, further contributes to the network’s diversity. Lyra, USDC, and USDT round out the composition with 7.39%, 6.28%, and 4.63%, respectively.

Total protocol revenue in the past 180 days has been $44,906.

Reward Claimer Analysis

Initial Transfer Of OP tokens from Optimism to CELER network

On August 4, 2022, Optimism initiated a significant transaction, transferring a 1,000,000 OP tokens to CELER Network. The OP tokens successfully received at the designated address: 0xf5e9d550c3c50364d630edb4753be404cd109121.

Transfer of OP tokens from CELER network to wallet address (Intermediate Wallet)

Within a short period of time, CELER Network executed a subsequent transfer, moving the OP tokens to an wallet 0x20f3880a281092dbc6699e5d5a0ff5feb3d3db1a which we will refer to as intermediate wallet address.

Distribution Of OP tokens to contract addresses

The intermediate wallet, disbursed a total of 220,001 tokens to FarmingReward Contract. Simultaneously, it transferred an additional 30,000 tokens to IncentiveEventReward Contract.

The following comparison is to demonstrate the significant upward movement that Celer can achieve in current market conditions and with the remaining grants at its disposal.


Celer Network has been around for a long time to analyze and realign their priorities for the success of the grants, though following are few points which can be looked into for better


Stimulating community participation through incentives in the Celer forum can indeed draw in new users. Additionally, expanding efforts to release new programs in collaboration with media teams can further bolster user engagement and awareness, contributing to the platform’s growth.

Broader Asset Targeting

While the current Farming Reward Campaign aimed at attracting high-value assets, the change in strategy could provide an edge over other protocols in the same category.

Reduced Entry Barrier

Allowing small stakes to be added to the liquidity pool & small amounts to be bridged can win new users trust for the protocol. The fact that crypto is global and GDP per capita varies vastly across countries should be considered.

Closing Remarks

The incentive support from Optimism to Celer has undeniably had a positive impact on growth, attracting more users than would have been possible without this program. Enhanced communication and broader outreach efforts by the Celer team can further amplify their growth within the Optimism ecosystem, especially considering the remaining available funds. Prioritizing builder grants, as originally proposed, also has the potential to drive significant user growth.



Yea it’s been an issue here for not just Celer Builder Grants, but also others that it is very hard to track + understand the impact

Thanks for the contribution and really comprehensive analysis!


Thank you for the update! So that we’re all on the same page, are you associated with Celer and delivering an official update or are you a community member unaffiliated with them?

This appears to be an EOA. Any chance you can describe (high-level) what security is helping to secure these funds since it’s not in an msig? If it’s a simple EOA, is there an opportunity to upgrade the security, since it’s still got 750k OP?

This grant was received in August of 2022, but 75% remains. That suggests Celer is struggling to spend the grant at scale as intended. Will Celer be presenting any revisions to help spend the grant funds in a more timely manner, or return part of the grant? Former is preferred.

This doesn’t look especially encouraging for the Farming Rewards portion of the grant. Also, just eyeballing the graph it looks like the Incentive Event led to a net outflow of assets from Optimism? Do we know how this compares across bridges? As in, do all of them (incentivized and unincentivized) have Optimism with a net outflow of assets or does the Incentive Event look like it encouraged outflows?

Also, for the avoidance of all doubt, Celer isn’t using the grant to subsidize assets leaving Optimism, correct?

CC: @jackanorak bc I know he loves to nerd out on this stuff and did an initial analysis last fall., and @modong since I think this is probably just a community member providing an update because of this comment:


I am not affiliated with Celer in any capacity. The contribution is part of the Deep Dive Analysis that I took up from NumbaNERDs mission. The aim of the report here is to understand how has Celer used the allocated funds.

It is an EOA.

I cannot answer on their behalf. But they haven’t answered the community ever since the month the grant was transferred. So would prefer them to reply in the grant proposal post.

Outflow was not incentivized, but the opportunity elsewhere of a similar type can lead to an inflow-outflow cycle.

You picked it right here. :grinning:

Also, I would restrict criticizing Celer as the report shall present facts and let the reader decide. :slightly_smiling_face:


I believe if 1 million OP are granted for mutual success, an additional 1%-3% shall be spent by appointing a “Grant Oversight Manager” who can be paid for the time with the grantee in shaping how it is spent and ensuring that it is spent timely.

Hi all,

Thank you for the review. Celer here. Quick note that the grant address is a MPC wallet instead of EOA. But we are considering moving this to a governance multisig smart contract wallet for sure.

We wanted to first acknowledge that we are also doing analysis on our end. We have been a long-term supporter of Optimism since day-1. Our intention and goals have not changed. To that end, we are looking into new and effective ways to utilize the grant for enabling new functionalities and applications on Optimism to bring more users and liquidity in. In addition to incentivizing cross-chain liquidity and builders to build Optimism-focused multi-chain applications, we are looking into enabling brand-new ZK coprocessing functionalities with grant subsidizing part of the costs of user and protocol usage. This will enable exciting functionalities such as gamer loyalty program, VIP trader program and a lot more user retention and acquisition features that were not possible to be built in a trust-free manner before.

A more complete proposal update will follow.


Hi @modong. Wanted to follow up here. For reference, the governance policy governing this would be:

The Hundred Finance (Phase 1 grant) request to alter their funding use provides a precedential ruling that Celer will need to submit a new proposal to the Grants Council or return the unused funds. This requirement is not something the Grants Council has control over, and was only recently clarified in the linked thread.

The Duration section of the original proposal suggests a new submission is needed

If you can confirm here whether Celer will be making a new submission or returning the funds, that would be great. If you are making a submission for changes, please reach out to @danelund.eth and/or @Gonna.eth if you need guidance on the process.


One important clarification: the Code of Conduct was updated to clarify this process at the end of March, and this clause has not been changed since, in alignment with the outlined Change Process.


Hi GFX Labs,

The timeframe and duration is based on factors such as $OP price, which at the time of writing had absolutely no reference other than an good faith estimation. The nature of such conditional estimation was described explicitly in the grant proposal.

Depending on the price of the $OP token,…

In fact, the price of $OP has seen more than 5.5X difference between highest and lowest point in the last ~1 year. That’s something that any good faith actor would not be able to see beforehand. The goal is always to best benefit the Optimism community with consideration of practical circumstances. There is no violation.

On the same note of supporting OP since day-1 and with more than $1.6M upfront incentive funding from Celer DAO with no promises whatsoever, we also explicitly noted in the grant proposal the following:

We also note that the amount of tokens contemplated here is subject to change depending on the traction we see in each of the programs.

What we are planning to do here is to provide an update on the grant distribution on our end and analyze the transaction we see in each of the proposed program. Based on such analysis, we will outline an clarification and update on the future focuses of growing Optimism ecosystem collectively in accordance to the original approved grant proposal.

In addition, with some new functionalities of Celer available on Optimism soon, we are beyond excited to discuss and gauge interests of incentivizing developer community to build on them and grow Optimism dApps with these new functionalities such as ZK-based trust-free user retention, acquisition and more features. If there are strong interests, we will submit a new proposal update according to the precedence. If not, we will stick to the original proposal per the approved grant and grant policies at the time of approval.

Thank you
