Predict the contract address a deployer will get from CREATE for a given nonce. The same on every EVM chain. Computed locally with RLP and keccak256.
Predict a CREATE2 contract address from deployer, 32-byte salt and either the init code hash or the creation bytecode. Computed locally.

Where a wallet is active: native balance, transaction count and contract flag on all 16 EVM chains in one call, with the most active chain.
Which of 16 EVM chains an address has contract code on, with a bytecode hash match to spot true multichain deployments versus look-alikes.
