Add full Qom X yields adapter

📝 WalkthroughWalkthroughUpdates the QOM-X BSC adaptor to query farms individually, calculate staked LP TVL and APR, derive missing reward-token prices, filter invalid pools, and return a placeholder for factory failures or empty results. ChangesQOM-X farm adaptor
Estimated code review effort: 4 (Complex) | ~35 minutes Merge Risk: 🟠 High · up to The adapter can currently return no yield pools, report APR for completed farms, and publish an incorrect token identity for its fallback pool. These behaviors can produce missing or misleading yield data, so the PR should not merge until corrected. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not hardcode 18 decimals for the LP token and the reward token.
totalStaked is scaled by the LP token decimals, and rewardPerSecond is scaled by the reward token decimals. Both are hardcoded to 1e18. If a reward token uses 6 or 8 decimals, yearlyRewards is understated by orders of magnitude and the reported APR is wrong. LP tokens are usually 18 decimals, but reward tokens on BSC frequently are not.
Fetch decimals for both token sets with an additional multiCall and use the returned values.

Exclude completed farms before APR calculation.
Line 53 removes a completed farm only when totalStaked is zero. Line 54 then removes every zero-stake farm. A completed farm with stake reaches lines 112-114 and receives an APR from rewardPerSecond for a full year.
Skip a farm when endTime is in the past. Preserve endTime === 0 if it represents no expiry. This also matches the PR objective to skip finished farms.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Set token: null on the placeholder pool.
The fallback uses FARM_FACTORY as pool but has no asset token. When token is omitted, downstream handling derives a token from pool. This publishes the farm factory as the token identity.
Add an explicit null token.

pls look at optimising this using multicall and diff structure, an example:
Current shape is ~10 sequential sdk.api.abi.calls per farm inside a for loop, plus a utils.getPrices call per farm. Across 11 farms that's ~110
RPC round-trips and 11 price requests, serial. Restructure into stages batched across all farms:
const mc = (abi, calls) =>
sdk.api2.abi.multiCall({ abi, calls, chain: CHAIN, permitFailure: true });
// 1. farm state — one multiCall per field, all farms at once
const [lpTokens, rewardTokens, totalStaked, rewardPerSecond, endTime, startTime] =
await Promise.all([
mc('address:lpToken', farms),
mc('address:rewardToken', farms),
mc('uint256:totalStaked', farms),
mc('uint256:rewardPerSecond', farms),
mc('uint256:endTime', farms),
mc('uint256:startTime', farms),
]);
// 2. filter to live farms BEFORE doing any further work
const live = farms
.map((farm, i) => ({ farm, i }))
.filter(({ i }) => lpTokens[i] && totalStaked[i] && BigInt(totalStaked[i]) > 0n);
// 3. LP state, live farms only
const lps = live.map(({ i }) => lpTokens[i]);
const [token0s, token1s, reserves, lpSupplies] = await Promise.all([
mc('address:token0', lps),
mc('address:token1', lps),
mc('function getReserves() view returns (uint112,uint112,uint32)', lps),
mc('erc20:totalSupply', lps),
]);
// 4. token metadata + ONE price call for every distinct token
const tokens = [...new Set(
[...token0s, ...token1s, ...live.map(({ i }) => rewardTokens[i])]
.filter(Boolean).map((a) => a.toLowerCase())
)];
const [decimals, symbols] = await Promise.all([
mc('erc20:decimals', tokens),
mc('erc20:symbol', tokens),
]);
const { pricesByAddress } = await utils.getPrices(tokens, CHAIN);
const dec = Object.fromEntries(tokens.map((t, i) => [t, Number(decimals[i])]));
const sym = Object.fromEntries(tokens.map((t, i) => [t, symbols[i]]));
const amt = (raw, token) => Number(raw) / 10 ** dec[token.toLowerCase()];
13 batched requests regardless of farm count, against ~121 today.
Two of the other findings fall out of this for free:
// decimals bug — no more hardcoded 1e18
const reserve0Usd = amt(reserve0, token0) * price0;
const reserve1Usd = amt(reserve1, token1) * price1;
const yearlyRewardTokens = amt(rewardPerSecond[i], rewardToken) * SECONDS_PER_YEAR;
// symbol: 'LP' -> the actual pair
symbol: `${sym[token0.toLowerCase()]}-${sym[token1.toLowerCase()]}`,
permitFailure: true keeps one bad farm from taking the batch down, which also removes the need for the per-farm try/catch that currently
swallows errors silently.
