Overview

Use this section when you need to understand the built-in programs themselves, not just the SDK package that talks to them.

Core Programs

Program	What it does	Main accounts	Events	Open next	Explorer
Passkey Manager Program	Turns WebAuthn/passkey proofs into on-chain authorization for nonce-bound program actions.	WalletAccount, CredentialLookup	wallet_created, wallet_validated, wallet_transfer, credential_registered	@thru/programs, @thru/passkey	View program
Token Program	Manages fungible token mints and token accounts.	TokenMintAccount, TokenAccount	initialize_mint, initialize_account, transfer, mint_to, burn, close_account, freeze_account, thaw_account	@thru/programs	View program
NFT Program	Manages NFT mint accounts, per-NFT accounts, transfers, burns, and metadata updates.	NftMintAccount, NftAccount	No event envelope is defined in the current flattened ABI.	ABI Examples, Specification	Public explorer page not currently documented in these docs.

Passkey Manager Program Learn the nonce, authority, and validate-then-execute model behind passkey-backed authorization flows.

Token Program Understand mint accounts, token accounts, lifecycle events, and the standard fungible-token instruction surface.

NFT Program See the NFT mint and NFT account model, instruction surface, and the current limits of the published ABI.

Next Steps

1. Read the program page for the contract you are actually targeting.
2. Move to the matching SDK package page when you need client helpers and builders.
3. Use the ABI docs when you need the binary layout or reflection model in more detail.
