Module pda 

PDA (Program Derived Address) helpers.

Direct syscall-based PDA creation and derivation. No external dependencies.

Functions

based_try_find_program_address

Find a valid PDA by hashing seeds directly and checking curve validity.

create_program_address

Create a program-derived address from seeds and a program ID.

find_bump_for_address

Find the bump seed for a known PDA address, skipping curve validation.

find_program_address

Find a program-derived address and its bump seed.

read_bump_from_account

Read the bump byte directly from account data at a known offset.

verify_pda

Verify that an account’s address matches a PDA derived from the given seeds.

verify_pda_from_stored_bump

Verify a PDA using the bump stored in account data (cheapest path).

verify_pda_strict

Verify that an address matches a PDA derived from the given seeds.

verify_pda_with_bump

Verify a PDA with an explicit bump seed appended to the seeds.

verify_program_address

Verify that an expected address matches the PDA hash for the provided seeds.
