## Name of Grant
InstaSwap: cross-chain rETH access. Acquire, receive, and get paid in rETH from any asset on any chain (including Bitcoin, Bitcoin Lightning, Solana, and Zcash), with an embeddable widget and partner API. ($15,000)
### What is the work being proposed?
We propose to make **rETH a first-class, cross-chain destination inside InstaSwap** and to ship it as a reusable **widget and partner API**, so that anyone, on any chain, holding any asset, can move into rETH in one step, with no manual staking and no wallet setup. Most of this already runs in production today: rETH is already a live swap destination in our engine, so **a user can convert BTC, SOL, USDT, and any asset across 67 chains straight into rETH delivered to their Ethereum or L2 address right now.** Every flow below can be tried in the live app today (see “Try it now”). This grant funds turning that into a dedicated Rocket Pool on-ramp with distribution.
Concretely, we will deliver a Rocket Pool “rETH toolkit” built on our existing rails:
- **Swap into rETH from anything, anywhere.** Any asset on any of 67 supported chains converts to rETH, walletless, delivered to the user’s address. Live today; we harden it into a dedicated flow.
- **Mint-preferred routing.** When the Rocket Pool deposit pool has capacity we route to primary mint (new rETH, growing TVL); otherwise we use best-execution on secondary markets. Either way the user simply receives rETH.
- **Get paid in rETH (Payments).** A payment link or page where whoever pays, in any asset on any chain, results in the recipient holding rETH. rETH becomes a receive currency, so income can accumulate into staked ETH automatically.
- **Split into rETH (Split).** Route a chosen percentage of an incoming payment into rETH automatically, for dollar-cost accumulation or for treasuries putting idle assets to work.
- **Receive rETH by name (ENS).** Send to a name such as `alice.eth` and the recipient receives rETH, cross-chain. Our cross-chain ENS resolution already ships in the product.
- **Private entry (optional), two modes.** A user can accumulate rETH with no public on-chain link between the source of funds and the rETH-holding address, either through a confidential rail or through a ZKProof mode, with settlement on-chain and no custodian in the middle. No other non-custodial on-ramp offers ZKProof or confidential entry into a liquid staking token.
- **Embeddable widget and partner API.** Every flow above is exposed through one integration, so any wallet, app, or Rocket Pool ecosystem project can add “Stake to rETH from anything” with a single change on their side, up to a full white-label deployment. This turns our distribution into net-new rETH demand across many front-ends, not just ours.
- **Revenue-share incentive for integrators.** Partners that embed the widget or API earn a share of the fee on the rETH volume they bring, funded entirely by InstaSwap at no cost to Rocket Pool. This gives wallets and apps a direct financial reason to promote rETH access, so rETH adoption compounds across many independent front-ends.
- **Public rETH dashboard.** A public page reporting the rETH brought into Rocket Pool through InstaSwap, verifiable on-chain.
The result: a cross-chain distribution layer for rETH that reaches an audience Rocket Pool has no non-custodial, integrable on-ramp for today (Bitcoin, Bitcoin Lightning, Solana, Zcash, and multichain stablecoin holders), with the acquisition made effortless (walletless, one step), settled on-chain without a custodian, and, optionally, private.

### Is there any related work this builds off of?
Yes. This builds directly on InstaSwap’s live infrastructure:
- A cross-chain routing engine spanning **67 chains** (including Bitcoin, Bitcoin Lightning, Solana, Zcash, Cosmos, XRP, Aptos, Cardano, and the major EVM L1s and L2s), already in production.
- A walletless swap product, a Payments product, and a Split product, all live.
- A partner API and affiliate system used by third-party integrators today.
- A confidential settlement rail for private execution.
- Cross-chain ENS name resolution, already shipped in the product.
On the Rocket Pool side it builds on rETH and, for mint-preferred routing, the Rocket Pool deposit pool. rETH is already enabled as a destination in our engine; RPL is also enabled (token `0xd33526068d116ce69f19a9ee46f0bd304f21a51f`).
**How this differs from what exists.** We want to be upfront about the landscape. Buying rETH with another asset is possible today through two kinds of services: EVM-only aggregators (which cannot originate from Bitcoin, Lightning, Solana or Zcash at all), and centralized instant exchanges that do reach those chains but hold user funds in custody, can freeze or KYC a transaction mid-flight, and offer a swap and nothing else. InstaSwap is neither: every rETH acquisition settles on-chain to the user’s own address with no custodian, and the same rails offer a confidential mode and a ZKProof mode that no custodial service can provide. Our rails are already used as infrastructure by third-party aggregators that resell our non-EVM routes, which is exactly the point: the routing exists and is proven. What does not exist anywhere, and what this grant funds, is a Rocket Pool-facing rETH toolkit on top of it: mint-preferred routing that grows rETH supply, get-paid-in-rETH and split-into-rETH flows, receive-by-name, an embeddable widget and partner API with revenue share so other front-ends promote rETH, and a public dashboard with a 90-day impact report to the GMC.
### Will the results of this project be entirely open source?
Partially, and we want to be precise.
- **Open (MIT):** the widget integration reference, the partner API documentation and examples for the rETH flows, and the public dashboard’s read/aggregation scripts can be published under MIT so the community can integrate and reproduce.
- **Publicly verifiable, not open source:** InstaSwap’s core cross-chain routing engine is the platform we operate commercially and will not be open sourced. It is, however, independently verifiable on-chain: the on-chain settlement (including the contracts involved) is public, every rETH delivery is an on-chain transaction, and the dashboard’s figures are checkable on Etherscan.
In short: the integration surface and reporting are open; the routing engine stays proprietary but its results are transparently verifiable on-chain.
## Benefit
| Group | Benefits |
|—|—|
| Potential rETH holders | A new way to get rETH from any asset on any of 67 chains (Bitcoin, Bitcoin Lightning, Solana, Zcash, multichain stablecoins), with no ETH required, no manual staking, no wallet setup and no custodian (settlement lands on-chain at the user’s own address), plus an optional private entry and platform reward points on every acquisition. This broadens who can realistically end up holding rETH far beyond people who already sit on ETH on Ethereum. |
| rETH holders | Net-new, structural demand that scales with adoption of the widget and the get-paid-in-rETH and split-into-rETH flows, plus deeper practical utility for rETH as a cross-chain receive currency. |
| Potential NOs | Indirect: growth in rETH demand and TVL strengthens the protocol economics that underpin node-operator revenue over time. |
| NOs | Indirect: the same demand and TVL growth supports commission economics and overall protocol health. |
| Community | A widget and partner API any Rocket Pool ecosystem app or wallet can embed to offer rETH access; multichain reach for rETH; and a transparent, on-chain dashboard of the rETH brought in through InstaSwap. |
| RPL holders | rETH TVL and demand growth is the primary driver of protocol revenue accrual; net-new, cross-chain, price-insensitive demand is constructive for RPL holders (indirect). Directly: RPL itself is now live as a cross-chain destination in InstaSwap, so RPL can be acquired from any asset on any of the 67 chains through the same walletless flow, widening access to RPL beyond Ethereum-native holders. |
### Which other non-RPL protocols, DAOs, projects, or individuals, would stand to benefit from this grant?
InstaSwap (the applicant) benefits commercially, earning its standard swap fee on rETH-routed volume, disclosed here and under Conflict of Interest. Wallets and apps that embed the widget or partner API benefit directly: they earn a share of the fee on the rETH volume they bring (funded by InstaSwap, at no cost to Rocket Pool), which gives them a standing financial incentive to promote rETH access to their users. Any ETH-holding DAO or treasury benefits too: the split-into-rETH and get-paid-in-rETH flows give them an easy, cross-chain way to move idle assets into rETH, which in turn is another channel of net-new rETH demand. We are already working with Nouns DAO, and treasury flows into rETH through these rails are part of that collaboration.
## Work
### Who is doing the work?
The InstaSwap team.
### What is the background of the person(s) doing the work? What experience do they have with such projects in the past?
The InstaSwap founding team that built and operates the platform described below.
- **Athanasios Kontos, Founder and CEO.** [LinkedIn](https://www.linkedin.com/in/sakis-k-instaswap/) | [X]( Sakis.INS (@tk_instaswap) / X )
- **Dim Maraslis, Co-Founder and CTO.** [LinkedIn](https://www.linkedin.com/in/dimitris-m-8176a87a/) | [X]( Dimitris M (@dim_instaswap) / X )
Our track record is the platform itself. InstaSwap is a privacy-first cross-chain platform that has been live for **8+ years**, with **over $2.03B in volume settled across 67 chains** and average settlement around 4 minutes, serving users today at app.instaswap.com. Our partner API and widget are already integrated by third-party wallets and platforms in production, which is the exact distribution channel this grant uses for rETH. The platform already spans native cross-chain swaps, Split Swap, Payments, Spot trading, Perpetuals, and tokenized stocks and ETFs, alongside a partner API, an embeddable widget, white-label deployments, an affiliate and revenue-share system, confidential and ZKProof settlement, cross-chain ENS resolution, and KYT/AML screening with fully non-custodial settlement. In other words, we have shipped and operated exactly this kind of cross-chain, walletless, multi-venue product at scale for years. The rETH-specific work below is a focused productization on top of that existing, in-production infrastructure, which is why it ships in one week.
### What is the breakdown of the proposed work, in terms of milestones and/or deadlines?
Our rails already exist and are in production (67 chains, walletless swaps, Payments, Split, the partner API and revenue-share, the confidential and ZKProof private modes, cross-chain ENS, and live rETH swaps). That is exactly why the timeline is short and the cost is low: the grant funds the rETH-specific work and the genuinely new pieces, not rebuilding infrastructure. Delivery is committed within **one week of approval**:
- **Days 1 to 3 (rETH-first flows plus new mint routing):** wire rETH as a first-class target into the existing Swap, Payments, and Split flows with a dedicated stake-to-rETH experience, and build **mint-preferred routing**, the main new component (route to the Rocket Pool deposit pool for primary mint when it has capacity, best-execution on secondary markets otherwise).
- **Days 4 to 5 (packaging for distribution):** package the existing rails into an embeddable “Stake to rETH from anything” widget and a documented partner API endpoint for rETH, connect the confidential and ZKProof private-entry modes to the rETH flows, and add receive-rETH-by-name on top of our existing ENS resolution.
- **Days 6 to 7 (reporting plus launch):** build the public rETH dashboard (new), test across the required assets, launch, and run joint education with the Rocket Pool community.
### How is the work being tested? Is testing included in the schedule?
Yes, testing runs throughout the week. We test cross-chain quote and settlement into rETH across the assets that must work (Bitcoin, Bitcoin Lightning, Solana, Zcash, USDT, ETH, and major stablecoins), the widget and partner API through integration tests, and the private entry path end to end. The dashboard reads on-chain, so its figures are independently verifiable. rETH swaps are already live today and can be tried before work begins through the links in “Try it now”.
### How will the work be maintained after delivery?
InstaSwap operates this as part of its live product. Ongoing routing, integration upkeep, and dashboard maintenance are part of running the platform at **no additional cost to the GMC**. No recurring Rocket Pool funding is requested.
## Costs
### What is the acceptance criteria?
Delivery (within one week of approval):
- Users can acquire rETH from any supported asset on any supported chain and receive it to their address, walletless.
- The embeddable widget and the partner API endpoint for rETH access are live and documented.
- Optional private rETH entry (confidential and ZKProof modes) is available.
- A public dashboard reports the rETH brought into Rocket Pool through InstaSwap, verifiable on-chain.
Measurable adoption targets (reported publicly on the dashboard, verifiable on-chain):
- **Within 30 days of launch:** at least **3 third-party wallets or platforms** live with the rETH widget or API, and the first cross-chain rETH acquisitions from **at least 5 non-Ethereum source chains** (including Bitcoin and Solana) settled and visible on the dashboard.
- **Within 90 days of launch:** a public impact report posted on this forum covering rETH acquired through InstaSwap, the share routed to primary mint versus secondary markets, source-chain breakdown, and integrator count, so the GMC can judge the outcome on data rather than on claims.
The grant payment is tied only to the delivery criteria above. The adoption targets are our public commitment and are reported regardless.
### What is the proposed payment schedule for the grant? How much USD $ and over what period of time is the applicant requesting?
**$15,000 total**, requested **as a single payment after acceptance**. No upfront payment is requested.
### Who will directly receive the payment? (Required)
USDC, ETH, or RPL on Ethereum mainnet to: **0x3758765532cfd0D55018e9A18f1aeB3dc9E26ca9**
### How will the GMC verify that the work delivered matches the proposed cadence?
On-chain and in-product. The GMC can confirm the widget and partner API are live, that a cross-chain swap into rETH works end to end, and that the public dashboard reports rETH brought in, all independently checkable on Etherscan and in the live product.
### What alternatives or options have been considered in order to save costs for the proposed project?
InstaSwap self-funds its core cross-chain engine, and rETH swaps are already live, so this grant is scoped only to the rETH-specific productization: the dedicated flows, mint-preferred routing, the widget and partner API, the private entry, and the public dashboard. Because the hard part (the multichain engine) already exists, the cost is small relative to the distribution and net-new rETH demand it unlocks.
### Have you already been compensated by the RP protocol in any way for this work?
No.
## Conflict of Interest
### Does the person or persons proposing the grant have any conflicts of interest to disclose?
No member of the GMC participated in this work, and to our knowledge no GMC member benefits financially from it.
### Will the recipient of the grant, or any protocol or project in which the recipient has a vested interest (other than Rocket Pool), benefit financially if the grant is successful?
Yes. InstaSwap earns its standard swap fee on rETH-routed volume and therefore benefits commercially if these flows succeed. We disclose this openly; the aligned outcome is that InstaSwap’s success is driven by, and drives, net-new cross-chain rETH demand.
