The Merkle proof of one ZK-compressed account, Solana only

The inclusion proof of a Solana ZK-compressed account by leaf hash — state tree, root, sequence, leaf index and Merkle path — or that no leaf carries the hash now.

What it returns

Returns the inclusion proof of one Solana ZK-compressed account, by its leaf hash: the state tree, the root the proof verifies against and its sequence number, the leaf index and the Merkle path. A program that reads or spends the account verifies this proof. found: false is a full answer, not an error: no leaf carries the hash now — the account was spent (every write replaces its leaf and hash) or never existed. The leaf hash of an account comes from compressed-accounts. The proof ages with the tree, so submit it promptly or ask again.

Parameters
Parameter	Description
`hash` query · string · required	The compressed account's leaf hash, base58. Required.
`chain` path · string · required	SOL. Every other chain returns 400: compressed accounts live in Solana ZK-compression state trees.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of The Merkle proof of one ZK-compressed account, Solana only
Field	Type	Description
`hash`	string	The leaf hash asked about.
`found`	boolean	True when a leaf with this hash is in a state tree now.
`slot`	integer \| null	The slot the tree was read at; null when nothing was found.
`proof`	object \| null	The inclusion proof. Null whenever `found` is false.
`proof.tree`	string	The state tree holding the leaf.
`proof.root`	string	The tree root this proof verifies against.
`proof.rootSeq`	integer	That root's sequence number; it moves every time the tree changes.
`proof.leafIndex`	integer	The leaf's position in the state tree.
`proof.path`	string[]	The sibling hashes from the leaf up to the root, bottom first.
