Build a keccak-256 sorted-pair merkle tree (OpenZeppelin convention) from a list
Build a keccak-256 sorted-pair merkle tree (OpenZeppelin convention) from a list of leaves and get the root plus a verification proof for any leaf — the standard construction for token airdrops and allowlists. Fully deterministic: same leaves, same root. Use this when an agent needs to root + proofs for airdrops and whitelists.
