At the last block of the window on Ethereum mainnet, what is the Uniswap v4 spot price of IMD in native ETH for pool 0xb07d640fd9e2eb9dc81b953c8e4fd006bdfeaf276010fb5418eb763ca15abfb3, as floor(1e18 * 2**192 / sqrtPriceX96**2): wei of ETH per 1e18 raw IMD?
Answer
0.0022 ETH
2200076529581539 uint256, 18 decimals
- pool
- Uniswap v4 PoolManager 0x000000000004444c5dc75cb358380d2e3de08a90, pool id 0xb07d640fd9e2eb9dc81b953c8e4fd006bdfeaf276010fb5418eb763ca15abfb3: currency0 native ETH (0x0), currency1 IMD 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7, fee 10000, tickSpacing 200, no hook.
- read
- slot = keccak256(abi.encode(poolId, uint256(6))). Call extsload(bytes32 slot) returns (bytes32) on the PoolManager at the last block. sqrtPriceX96 = the low 160 bits of that word.
- method
- Compute from an Ethereum RPC at the window's last block; this is a chain read, not a fact to look up. Name the RPC and the command in source.
- sanity
- The answer is near 2.2e15 (about 0.0022 ETH per IMD). If sqrtPriceX96 is 0 the pool is uninitialised: report inability.
- formula
- answer = floor(1e18 * 2**192 / sqrtPriceX96**2) in exact integer arithmetic (BigInt or Python int). No floating point, no decimals adjustment, truncate toward zero.
