feat: route gasless voting through governance vote-relay, drop gelato by JoaquinBattilana · Pull Request #3077 · aave/interface

JoaquinBattilana · 2026-07-22T03:30:26Z

Summary

Routes gasless governance voting through the new governance vote-relay (governance-v3-cache PR #126) and removes the Gelato relayer, whose sponsor flow required calldata built in the browser and a key managed outside our infra.

The relay now encodes submitVoteBySignature server-side, so the browser only sends the raw voting-balance proofs plus the EIP-712 signature. The browser never holds the relay API key — it calls a same-origin Next.js proxy that attaches the server-side key, mirroring pages/api/rpc-proxy.ts.

browser ──sign + POST──> /api/governance/vote-relay/* ──x-api-key──> vote-relay ──> VotingMachine

Changes

New pages/api/governance/vote-relay/[...path].ts — same-origin proxy. Attaches server-side x-api-key, forwards the caller IP as x-forwarded-for (relay's per-IP rate limiter keys on it), and passes the relay's status/body straight through. Allowlists only the relay's vote routes (incl. /v1/votes/representative) so it can't be used as an open proxy.
New src/components/transactions/GovVote/temporary/voteRelayClient.ts — submitRelayVote (POST raw proofs + signature) and pollVoteStatus (polls until MINED/CONFIRMED; fails on FAILED|EXPIRED|CANCELLED|DROPPED; keeps waiting on PENDING|INMEMPOOL|REPLACED), plus a typed RelayError { code, retryable }.
Edit GovVoteActions.tsx — the gasless branch now signs (unchanged EIP-712) → POSTs to the proxy → polls status. On RELAYER_UNAVAILABLE it falls back to the self-paid submitVote; any other relay error (bad signature, already voted, simulation reverted, vote in flight) surfaces to the user.
Edit VotingMachineService.ts — dropped the now-unused generateSubmitVoteBySignatureTxData (the relay encodes calldata itself).
Removed pages/api/gelato/relay.ts and the GELATO_SPONSOR_KEY env var.
Env — added VOTE_RELAY_URL + VOTE_RELAY_API_KEY (server-side only) to .env.example.

The NEXT_PUBLIC_ENABLE_GASLESS_VOTING gate is unchanged. When the relay is unconfigured, the proxy returns RELAYER_UNAVAILABLE and voting falls back to self-paid, so nothing breaks before the relay is live.

Notes / out of scope

Representative voting UI is not included. The proxy forwards /v1/votes/representative, but there is no client logic for SubmitVoteAsRepresentative signing / proofOfRepresentation / represented-voter selection yet — a separate follow-up.
Not verified end-to-end against a live relay (needs a staging VOTE_RELAY_API_KEY and an in-window proposal). Verified by typecheck + lint; happy path is logic/types only.
Depends on governance-v3-cache PR feat: staking page #126 being deployed. Stacked on feat/governance-cache-sdk (the branch that introduced the Gelato flow this replaces).

Testing

tsc --noEmit clean.
ESLint + prettier clean on all touched files.

@JoaquinBattilana Do we need to add this to vercel?

nit: we should add typed env vars as we have in v4 (in a separated PR)

Yeah agreed

no need to be env var this one i think

📦 Next.js Bundle Analysis for aave-ui

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
`global`	`1.32 MB` (🟡 +10 B)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

If you want further insight into what is behind the changes, give @next/bundle-analyzer a try!

Six Pages Changed Size

The following pages changed size from the code in this PR compared to its base branch:

Page	Size (compressed)	First Load
`/`	`96.01 KB` (🟡 +2 B)	1.42 MB
`/dashboard`	`85.59 KB` (🟡 +2 B)	1.41 MB
`/markets`	`54.89 KB` (🟡 +2 B)	1.38 MB
`/safety-module`	`56.45 KB` (🟡 +2 B)	1.38 MB
`/sgho`	`92.99 KB` (🟡 +2 B)	1.41 MB
`/v3-migration`	`52.64 KB` (🟡 +2 B)	1.37 MB

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
