The assessment will primarily focus on a fee-and-burn mechanism on stablecoin payment rails and on lock-and-earn primitive for ecosystem participants, as protocol-level fee burns tied to network activity are harder to implement as permissionlessly and autonomously as the model requires for a successful implementation. We'll then recommend whether to ship one or a combination, and then build and ship the selected mechanism to mainnet within the grant horizon. This is because the RFP set became public only on June 9, so a short, time-boxed assessment must be the first step rather than pre-committing to a mechanism before a thorough analysis. ScopeLift has extensive experience building production fee-collection, value accrual, and staking infrastructure, having authored ZKsync's [Fee Flow system](https://forum.zknation.io/t/zk-token-fee-flow-system-v1-0-overview/983) and Uniswap's [UniStaker](https://docs.unistaker.io/). Currently we're also engaged with a major Ethereum L2 doing comparable value accrual design and implementation work, which we'll be able to disclose in private. 2.2 Who does this work support?

Routing network revenue into FIL value accrual is a measured cryptoeconomic output}) and reinforcing the value accrual case that supports the paid-deal flywheel (Objectives 1 {Indirect: The mechanism is downstream of paid deals: more paid deals produce more value accrual. It strengthens the value accrual case for the paid deal flywheel but does not itself originate deals} and 3 {Indirect: Stronger, verifiable FIL value accrual supports the ecosystem case for adoption, but the mechanism does not drive client adoption directly}). 3.2 Verification metrics | Metric | Data source | How it's measured | Target (end of grant) | | --- | --- | --- | --- | | Cumulative FIL value accrued via the mechanism | Onchain: contract events + FIL routing path; explorers | Sum of FIL routed into accrual (burned or locked, per the M1 design) | To be defined in M1 | | Stablecoin volume routed through the mechanism | Onchain: contract events | Total stablecoin value processed | To be defined in M1 | | Dashboard live and tracking | Labeled onchain address + public dashboard + open source indexer | Dashboard reflects onchain value accrual and volume within a defined latency | Live by end of grant | 3.3 References - Compound Foundation - Optimism Foundation and OP Labs - Uniswap Foundation and Uniswap Labs 4.1 Monthly Operating Burn [ "$10-$100K (small team)" ] 4.2 What % of total team monthly burn depends on this grant? 0% 4.3 If this grant is not awarded, what happens? ScopeLift is an established firm and continues operations as is. 4.4 Core Team Details and profiles of the ScopeLift team can be found in [this page](http://scopelift.co/team). ScopeLift is a full-stack crypto engineering house. We’ve been building since 2016 for some of the top teams in the industry, from Optimism and Uniswap to Tally, Wormhole, ZKsync, Project Eleven, Gitcoin and more. Our areas of focus are privacy, governance and all things DeFi. We've built ZKsync's Fee Flow system and Uniswap's UniStaker. We're currently building another value accrual mechanism for a major Ethereum L2. We're also the stewards of Umbra Cash (where we developed the ERC-5564 and ERC-6538 stealth-address standards) and in March 2026 took over operation of Tally's governance platform, having previously built the Flexible Voting extension to OpenZeppelin's DAO Governor. 4.5 Has your team received a ProPGF grant or funding from PLFIF before? [ "No" ] 5.1 Key risks & dependencies - Mechanism selection: the right mechanism for FIL is not assumed up front. This is mitigated with Milestone 1 and with this RFP process. - Implementation lane: Filecoin pushes for a mechanism outside of ScopeLift's expertise. This proposal is structured so that such a choice is out of scope and protocol-level options were set aside up front for the time being. - External dependencies: FIL routing/sink paths, DEX liquidity and stablecoin rail readiness are also pinned down in discovery. And we target Calibration testnet first with a documented mainnet path. - Filecoin onboarding: ScopeLift is EVM-native and transfers to FEVM, but Filecoin-specific tooling and semantics carry a ramp-up cost, budgeted into discovery. - Security and audit: a mechanism handling real payment flows is security-critical, and ScopeLift has proven experience with other crypto blue chips in delivering audit-ready code with extensive integration, fuzz, and invariant testing. This ensures auditors can optimize their time to focus on the most critical vulnerabilities. Any feedback you have on the application process? Smooth and sound! Anything else you want to share that we didn't ask? The proposal's output is built intentionally as a reusable primitive, so successful delivery is a natural foundation for follow-on work on more complex protocol-level burns and primitives.
