Program accounts & PDAs

Source-derived account layouts, fields and canonical PDA seeds for the frozen Core program.

These accounts exist in Core v0.1.0. PDAs are derived under the official program ID; use the SDK's pda exports rather than hand-writing seeds in application code.

State accounts

Account	Key fields / role	Serialized account size
`Pool`	Authority, token mints, LP vaults, fee vaults, creator recipient, LP mint, `fee_bps`, version and `swap_nonce`.	372 bytes
`ShieldedState`	Pool/mint bindings, custody A/B and active tree pointer.	202 bytes
`TreeState`	Pool, generation, index/sequence, 16-level frontier, empty subtrees and 32-root history.	2,672 bytes
`PageDirectory`	16 page roots, raw-page hashes, canonical bumps and generation binding.	1,122 bytes
`LeafPage`	Generation/page header, leaf count, chunk hashes and trailing 32-byte commitments.	597-byte header; maximum 131,669 bytes
`SpentNullifier`	Pool, 32-byte nullifier and version.	73 bytes
`ProtocolConfig`	Protocol authority, fee recipient, bump and version.	74 bytes

Sizes include the Anchor discriminator. LeafPage maximum includes the full 4,096 commitments for one page.

Canonical seeds

PDA	Seeds
Pool	`pool`, mint A, mint B, fee tier as little-endian u16
LP vault A/B	`vault-a` or `vault-b`, pool
Protocol/creator fee vault	`protocol-fee-a/b` or `creator-fee-a/b`, pool
LP mint / lock	`lp` or `lp-lock`, pool
Shielded state	`shielded`, pool
Tree generation 0	`tree`, pool
Tree generation >0	`tree`, pool, generation as little-endian u64
Page directory	`page-dir`, pool, generation as little-endian u64
Leaf page	`leaf-page`, pool, generation as little-endian u64, page index byte
Spent nullifier	`spent`, pool, nullifier bytes
Protocol config	`protocol-config`

The tree has 16 pages per generation; page indexes range from 0 through 15. See tree paging for page composition and Reference: instructions for instruction account groups.
