Quotes and state

Read BondingCurve and LaunchLens; use the RPC proxy for eth_call.

Quotes and progress come from on-chain reads. Prefer the bonding curve and LaunchLens over trusting any off-chain price for settlement.

tsreadCurve.ts

import { parseAbi } from "viem";

const curveAbi = parseAbi([
  "function getPrice() view returns (uint256)",
  "function getReserves() view returns (uint256 reserveNative, uint256 reserveToken)",
  "function bondingProgressBps() view returns (uint256)",
]);

const price = await publicClient.readContract({
  address: curveAddress,
  abi: curveAbi,
  functionName: "getPrice",
});

const progressBps = await publicClient.readContract({
  address: curveAddress,
  abi: curveAbi,
  functionName: "bondingProgressBps",
});

LaunchLens (indexers)

tslaunchLens.ts

import { parseAbi } from "viem";

const lensAbi = parseAbi([
  "function tokenCount() view returns (uint256)",
  "function getLaunchRecord(address token) view returns ((address token, address curve, address creator, uint256 createdAt))",
]);

const record = await publicClient.readContract({
  address: lensAddress,
  abi: lensAbi,
  functionName: "getLaunchRecord",
  args: [tokenAddress],
});

For charts and indexed trades, use GET /tokens/:address/chart and GET /tokens/:address/trades. Chart intervals: 1s, 1m, 5m, 15m, 1h, 4h, 1d (default 1m).

Read-only RPC proxy

bashrpc.sh

curl -sS -X POST "${API_URL}/rpc" \
  -H "content-type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'

Write methods (eth_sendTransaction, etc.) are rejected. Frontend mainnet reads often use VITE_API_URL/rpc.
