The price of a token on NEAR Intents is the ratio inside a trade that
`intents.near` actually executed; there is no pool, oracle or stored price,
and a 1Click quote is an offer. This reads `execute_intents` transactions on
the contract's shard, keeps the `token_diff` legs whose receipt succeeded and
whose intent is in `intents_executed`, and records one trade per asset/counter
pair per outcome, counting each unit once whichever side the taker was on.
- core: event parsing, trade building, shard lookup, price and VWAP, tested
against the logs of mainnet tx 85uy9uCF (USDT on Tron for ZEC).
- data: a NEAR client over the existing RpcClient, live then archival;
migration 0009 (intents_trade, intents_scan, near_token).
- api: a contiguous-cursor scan and a supply/listing poll per chain, and
GET /v1/chains/{chain}/intents/{swaps,price}. Prices are in counter-token
units; no USD until a stablecoin is named by contract.
Gated on `[chains.intents]`, which the config template leaves commented out:
FastNEAR's free RPC sustains about two requests a second against ~1.7 needed
to follow the tip, and neardata allows 30 blocks a minute. It waits for our
own node. A test renders the template and fails if the block is enabled.
Verified end to end against mainnet with ZEC configured: the trade at NEAR
218,261,895 was recorded and served by both routes.
