Champion request for proposal #778 (RFP 13, Canton Venues)

Hello all,

I'm Oleksii Vasyliev, author of proposal #778, "Canton Venues: Open Market Data for Canton Trading Venues", under RFP 13 (Payments and DeFi): https://github.com/canton-foundation/canton-dev-fund/pull/778. It has been open since 9 September and came through the 22 October cleanup, but it is still in Incoming with no champion and no review.

What it does today, in public: cantonvenues.com compares the same trade across six Canton venues (Temple, Cantex, Tradecraft, Rocky, Pool Party, OneSwap) at sizes from $100 to $50K, after each venue's network fee. Every hour it checks its own prices against the venues' own quote engines. The run at 11:20 UTC today matched 168 of 168 quotes from Tradecraft, Cantex and OneSwap (https://cantonvenues.com/api/v1/quotecheck.json). The API is open and needs no key. Since 13 October an outside client we don't know has read ten of its files every two minutes, around the clock, about 7,200 requests a day; the latest came at 12:19 UTC today. Cantex left a public comment of support on the PR on 8 October. The Foundation has also run the code it is built on: reviewing milestone 3 on #313 on 12 August, Jatin ran the toolkit's integration report on testnet, 58 passed and 0 failed. Since 22 October I'm a member of the DeFi Protocols & Liquidity SIG.

CIP-0100 says the Tech & Ops committee should ask one of its members to champion an external proposal. Could the committee look for a champion for #778? If something in the proposal keeps it from going forward, I'd be glad to hear what and fix it.

Thank you,
Oleksii Vasyliev
