L2 recipient address: 0xa07D75aacEFd11b425AF7181958F0F85c312f143

Which Voting Cycle are you applying for?: Cycle 8

Grant category: Tooling

Is this proposal applicable to a specific committee? (If so, please link to committee): Yes. This falls under the Optimism Tooling/Infrastructure Committee - [DRAFT] S02 Committee Proposal: Tooling Governance Committee 5

Project description (please explain how your project works):

Ambire wallet is an open-source smart wallet focusing on security and UX. Fully self-custodial, it offers custom dApp interaction and gas optimisation solutions, features email/pass access, upgradable security (including multisig) and native swap, cross-chain and earning functions. Community ownership and governance is ensured through a native token.

Project links:

Additional team member info (please link): Check Team Members here.

Please link to any previous projects the team has meaningfully contributed to: Before Ambire Wallet, the Ambire team developed AdEx Network, the first decentralized ad network built on Ethereum and the biggest payment channels network on Ethereum.

Relevant usage metrics (TVL, transactions, volume, unique addresses, etc. Optimism metrics preferred; please link to public sources such as Dune Analytics, etc.):

Currently there are more than 92,000 registered wallets, 12,000 of which hold funds. Most used chains on Ambire are Ethereum, Polygon and BSC. At the moment Ambire wallets volume on Optimism is modest, but it has a good potential, so an OP incentive will help us promote Optimism among Ambire users and increase Optimism TVL.

Is/will this project be open sourced? Yes, all major components are open-sourced already

Optimism native?: EVM native

Date of deployment/expected deployment on Optimism: May 13th, 2022 (Announcement)

Ecosystem Value Proposition:

What is the problem statement this proposal hopes to solve for the Optimism ecosystem?

The EVM ecosystem, including Optimism has always been particularly challenging to build a wallet for, due to a few underlying characteristics that ultimately lead to user inconveniences:

  • It’s complicated to create a wallet and learn the importance of protecting a seed phrase; this requires 5x more time than creating an account on any web2 app.
  • Most desktop wallets require installing an extension, which is a not a natural flow for web2 users.
  • Multiple transactions needed to deposit into DeFi protocols, stuck transactions due to gas fees; you also need ETH or the chain’s native currency to transact.
  • Generally bad and overcomplicated UX - most wallets don’t parse transaction data in human readable way which paves a way for scams, social engineering attacks and user errors.

How does your proposal offer a value proposition solving the above problem?

Ambire Wallet is an open-source smart contract wallet and has been built with security and ease of use in mind. It is designed to satisfy and improve the user experience of both newcomers and degens in ways impossible for existing EOA wallets.

Ambire Wallet started as a web app, but soon native iOS and Android apps will be released, together with Chrome extension. The web app is mobile-friendly and 100% usable on mobile browse.

Some of Ambire’s game-changing features:

  • Sign up with an email/password without compromising the self-custodial nature of Ambire Wallet (*how it works*);
  • Paying transaction fees in stablecoins;
  • Transaction preview: before signing a transaction, we show a human-friendly description of what it does, step by step;
  • Automatic transaction fee management, automatic front-running/sandwiching protection via Flashbots;
  • Transaction batching: ability to do multiple actions in one transaction (e.g. combining token approval and swap on Uniswap in the same transaction, instead of signing two);
  • Multiple signers (keys) can be used to control the same account: e.g. a hardware wallet (Trezor, Ledger and Grid+ Lattice1 support) AND a software wallet; those can be easily enabled or disabled;
  • Connect to any dApp through WalletConnect, built-in dApp plugin system for a secure and faster connection with a curated set of dApps (new ones being added gradually);
  • Available on Optimism and 11 more EVM chains, built-in cross-chain aggregator for a seamless transfers between L1 and L2.

You can create a wallet with email and password only, or if you prefer use hardware wallet or Metamask as a signer:

Find the best routes for bridging between L1 and L2:

Human-friendly transaction parsing, pay for network fees in stablecoins and other ERC-20 tokens, automated gas management:

The Ambire dApp catalog:

Why will this solution be a source of growth for the Optimism ecosystem?

Ambire Wallet is on a quest to solve important UX problems of EVM wallets that prevent wider adoption. We believe that we are very well positioned to do it with account abstraction and the benefits of smart contracts over EOAs.

The Optimism ecosystem will benefit from a wider adoption of Ambire Wallet, as it will reduce friction both for novice and experienced users, bringing UX improvements and smart wallet features that currently no other wallet solution on Optimism can offer.

Ambire’s dramatically improved UX, combined with Optimism’s high performance and scalability can pave the way to onboarding the next billion users to crypto.

Has your project previously applied for an OP grant? No

Number of OP tokens requested: 425,000

Did the project apply for or receive OP tokens through the Foundation Partner Fund?: No

If OP tokens were requested from the Foundation Partner Fund, what was the amount?: N/A

How much will your project match in co-incentives?: We will run a governance proposal on our end to introduce a limited-time (while OP is distributed) $WALLET multiplier for Optimism users to support the incentive.

TLDR: The $WALLET token is distributed to Ambire Wallet users based on the amount of funds they are holding in their wallets. There are several multipliers of these rewards that some users are eligible for, e.g. early users; users who transact often, etc.

We will introduce a 1.25x $WALLET multiplier for users who really use Optimism often (more than 10 transactions in 30 days). The introduction of the multiplier will add $WALLET tokens to the OP allocation, so it will be an additional incentive on our side.

Proposal for token distribution:

All of the $OP allocation will be distributed as an incentive:

I. For users to explore and use Optimism with Ambire Wallet, to bridge assets to Optimism within Ambire Wallet

  • 17% $OP will be distributed as an incentive for users to bridge funds onto Optimism with Ambire
  • 12% $OP will be distributed as an incentive for users to swap on Optimism inside Ambire Wallet
  • 23,5% $OP will be distributed as an incentive for users to hold OP in their wallets instead of dumping
  • 23,5% OP will be distributed as an incentive to complete OP quests using Ambire Wallet

II. For developers to integrate Optimism-native dАpps into Ambire Wallet and direct Ambire Wallet connection

  • 12% OP wil be distributed as an incentive for dАpps to create Ambire dApp catalog compatible dApps

Ambire dApp catalog main page:

Lido Staking dApp loaded in the dApp catalog:

  • 12% $OP will be distributed as an incentive for Optimism-native dApps to integrate direct Ambire connection (connect with Ambire) and skip the WalletConnect modal on Optimism, e.g. Lido (Ethereum):

Allocations and Targets

Incentive For OP Allocation Period Target
Bridge funds Users 75,000 Proportional to bridged sum (capped to prevent :whale: draining the whole allocation). Each account will be eligible for one allocation per month ( to reduce sybil). 3 months 3,000 addresses with bridged funds from all EVM networks to Optimism for 3 months
Swap Users 50,000 Proportional to swapped sum (capped to prevent :whale: draining the whole allocation). Each account will be eligible for one allocation per month ( to reduce sybil). 3 months Volume swapped more than $100,000
Hold Users 100,000 Proportional to OP held and gradually unlocked if users hold OP in their Ambire wallets for a longer period 6 months TVL OP held on Optimism ~ $1m
OP Quests Users 100,000 Reward users who complete all 18 Op quests using Ambire wallet 3 months 3,000 Ambire users to complete all 18 OP quests
Integrate into dApp catalog Devs 50,000 Reward/incentivize developers who integrate their protocols in the Ambire dapp catalog - targeted for all native Optimism dapps 3 months 25 dApps added to the Ambire dapp catalog
Integrate direct Ambire connection Devs 50,000 Incentive for Optimism-native dApps to integrate direct Ambire connection (connect with Ambire) on Optimism, e.g. Lido (Ethereum): 3 months 25 dApps with direct Ambire connection


We will apply all standard practices like on-chain behaviour analysis to prevent sybil manipulation. Additionally we will simply try to incentivise users to stick to 1-2 wallets, instead of creating additional ones:

  • Introduce a limitation of rewards per account that still allows users to get the same reward multiple times if they continually and reasonably use the wallet on Optimism - e.g. get rewards for bridging and swapping every month
  • Stimulate users to hold OP in their wallets and reduce dumping of the OP tokens and incentivize long term usage of both Ambire and Optimism
  • Introduce $WALLET reward multipliers for frequent use of wallets on Optimism, additionally incentivizing people to stick to one wallet

Please provide any additional information that will facilitate accountability:(smart contracts addresses relevant to the proposal, relevant organizational wallet addresses, etc.)

All Ambire Wallets have the same bytecode (you can find the bytecode here) and are minimal proxies with this contract as base: 0x2a2b85eb1054d6f0c6c2e37da05ed3e5fea684ef

This method of facilitating accountability is unique for Ambire Wallet and not possible with regular EOA wallets.

@vanzoo do you plan to add ERC-4337 account abstraction support in the near future?

1 Like

I think it was great idea!!

We already support account abstractions as we’re a smart contract wallet. It’s possible to support ERC 4337 too in the future but for now it’s not needed as we use our own relayer.

The idea with ERC 4337 is to have a public decentralized mempool that serves all contract wallets, so that centralized relayers are no longer used. If you rely on your own relayer, your users could be censored by someone DoSing it, or by legal action forcing you to censor a specific user or a specific destination (e.g. any user attempting to use TornadoCash).

You probably don’t maintain an Ethereum node which your users must use, and they’re free to use any node. For the same reason, they shouldn’t have to use a specific relayer to interact with their wallet.

We are aware of this and we are planning on supporting 4337 once the infrastructure is in place. We’re also in touch with Kristof who co-authored ERC4337 so we can see if it’s possible to modify/extend it so that already deployed immutable wallets can support, rather than having to migrate users to add the extra function

When you say most of the code is opensource what do you mean? What is not opensource? Will the new mobile apps you mentioned be opensource?

How did you arrive on the 425,000 OP tokens number? Isn’t 3 months too small a period for this amount of tokens? Wouldn’t it make sense to push it all to at least 6 months?

  1. Only the relayer is not open-source at the moment. But it’s important to note that you can use Ambire without the Relayer, but you won’t have stablecoin fee payments.

  2. The mobile apps will be open-source :fire:

  3. We seriously aimed for 420,069 but guys at Rainbow were faster… Seriously, we thought about few different incentives:

  • Incentive for “discovering” Optimism on Ambire
  • Incentive for swapping
  • Incentive for holding
  • Incentive for developers

With acquisition of new users we aimed at up to $30 acquisition cost per user; incentives for swapping are meant to encourage people to diversify their portfolio on Optimism; incentives for holding were calculated so that they are lucrative enough for users to hold; incentives for developers are ~ up to $2000 per integration which should be enough to cover development and marketing costs ( shout outs, announcements, co-marketing with developers).

  1. We read that shorter periods are preferred when applying for OP grants, so we tried to fit most of the incentives in 3 months. However, we agree that 6 months periods increase chances to meet the targets and create sustainable traction. We are willing to change periods to 6 months for all incentives.

At first glance it seems like adding the required functionality to Identity is not too complicated. However, wrapping the deployed wallet with 4337 functionality will be more challenging since your fallback function doesn’t implement external “fallback handlers”. Gnosis Safe was able to add the functionality through wrapping, but adding a module and a fallback handler that implements the validation function. Without this, it can be a challenge.

IMHO this increases the urgency of adding at least a stub for future support, so less users will need to migrate.

If the relayer is just for stablecoin payments, how are ETH gas payments handled without it? Doesn’t it require the user to maintain an additional funded EOA and act as a self-relayer?

Adding the function to Identity would be easy but as you’ve figured out we cannot add it for existing users without a migration. We will consider a Safe-like approach but generally we avoid fallback function modules for simplicity and security reasons (eg an exception or extra gas usage in the fallback function would render the wallet unable to receive ETH)

Indeed, you need to have an EOA funded with ETH and you act as a self-relayer in relayerless mode.

Generally, we believe the dependence on a proprietary relayer to be an important issue to solve but not the biggest blocker for smart wallet adoption, which would currently be the fact that many web3 applications do not implement EIP1271. To address this we are working on a pull request to ethers.js to add a built-in function for message validation that is EIP1271 compliant

Indeed, not the biggest blocker, but censorship resistance can suddenly become important when you least expect it, and then you need it the most. We’d like to solve it for everyone well before it becomes an issue.

I hope that any functionality in your relayer can be implemented as an ERC-4337 paymaster. E.g. pay gas with a stablecoin is possible. If you have any functionality that cannot be addressed with the current design, we’d like to learn about it and see how we best serve your wallet.

Definitely, that’s the biggest adoption blocker. It’s great that you’re working on a PR for ethers.js for this. One thing to keep in mind when implementing this, is to check for EIP1271 before checking the signature. Right now the order doesn’t matter but we’re working on an EIP to add code to existing accounts. When EOA can be converted to a contract, it’s important to invalidate its old ECDSA key. Hence, if the account has code, the module should refrain from ecrecover.

Regarding the sybil resistance for the incentives how do you plan to make it work? Even with limiting per account what stops me from making as many accounts as I want?

No one has yet completely eradicated sybil exploits and probably neither will we, but we believe that we can mitigate it to some extent:

  • We won’t limit people to claim only once per account, but introduce a conscious multimple claims during a longer period. This will probably incentivize people to use the accounts over time and stick to them. This will be combined with:

If you know that you will get even more OP if you use the wallet often, you will probably try to optimize how you are using it and invest your time to create the optimal allocation of your funds.

This doesn’t mean there won’t be any wash trading or sybillers, but being a wallet we believe that we are in a good position to have people stick to one account and get more OP on one place instead of wasting time to create more accounts.

Of course additionally we can analyze on-chain activity and make it harder for wallets to be eligible for OP incentives - set minimum amount of transactions to be made or detect if wallets are just moving the same tokens between each other to simulate activity.

There are two other proposals quite similar to this one:

What all three have in common is that they mean to incentivize wallet users to use Optimism (with the given wallet) and perform some special actions like swapping tokens or holding OP for a specific period of time.

However, all of them lack detailed plans on how they are supposed to distribute funds to the users. The Rainbow team mentioned that they are already working with some people from Optimism Foundation in order to come up with some incentive structure.

I believe that all wallets should have the same incentives structure or at least that their incentive structures should not be competitive - it wouldn’t make sense for Optimism to pay more for swapping tokens in one wallet than in another wallet (of course each wallet is free to additionally reward users for those actions apart from OP rewards). Moreover, Rainbow proposal introduces KPI milestone that needs to be achieved before releasing additional funds (only 30% of the requested amount is released upfront), I believe that the other proposals should also include similar KPI requirements. Given that I believe that a common incentive structure should be obtained before proceeding further with such proposals.

Furthermore, both TallyHo and Ambire proposals include using ~25% of the allocated funds in order to incentivize dApp developers to integrate with their wallets. I believe this part of the proposal should be excluded to a separate one so that community would be able to decide if OP should directly fund this (as this benefits more the wallet itself and not OP ecosystem) and those grants if separated would be substantial by themselves (~100k OP). To be clear - I’m not against OP funding this, just would like to see it separated from the grants to incentivize using Optimism with the given wallet (also to be able to compare those grants as apples to apples).

Moreover, it might be worth considering making sure that OP is not rewarding the same wallet for using Optimism across different wallets. Right now it feels like overkill to me, but from OP perspective it’s quite possible that a single user will farm OP rewards for the same Optimism activity in every wallet with an incentive structure (yet I’m not sure if that’s necessarily bad).

To summarise, what I propose would be to:

  1. Separate wallet integration into separate proposals.
  2. Streamline the work on incentive structure between Rainbow, Tally Ho, and Ambire to have a common incentive schema between wallets (or at least make sure that common parts between wallets are not competitive).
  3. Wait before proceeding with any additional grants related to incentivizing using Optimism in wallets until the common incentive structure is obtained.

Of course, in order for this plan to work it would be necessary to effectively work on the common incentive structure, but each of the projects needs to figure it out before implementing anything anyway, so it seems like a good milestone whatsoever.

I’ve posted a similar comment in the other mentioned thread.

I’ll start to ask for tips for the copy/paste hahah jk, I’m glad to see others using this, I’m tempted to make the whole delegate list.

About the proposal I like it but as @kaereste said I feel all wallets should be treated equally, given the same amount, and set up the same compensations to users.

I’m tempted to even cross reference addresses to avoid the same address to get the compensation from all 3 wallets.

Hey @kaereste & @Gonna.eth thank you for your comments - very valid points in there.

About the developer grants - yes, they might have more obvious benefit for Ambire/the wallet, but overall a wider adoption of these dapps in wallets means wider adoption of Optimism as well, because users will have more things they can do on Optimism, so I don’t think that’s bad. However, we are okay to separate those two types of grants from the rest as another proposal.

About the common incentive schema between wallets - By no means we want to compete with other wallets solely by the amount of OP distributed to users. We believe that competition should be on the field of user experience and features and equal compensation standard for users is a great idea in this sense.

That being said we will be very happy to work together on such schema with the Rainbow, Tally Ho and Optimism foundation teams.
