Solana side

The six Anchor programs that handle wPRL on Solana.

Six Anchor programs split the on-chain logic by responsibility:

Program	Responsibility
nacre_two_way_peg	Mint/burn state machine. Owns deposit attestations, withdrawal requests, fee math.
nacre_liquidity_management	wPRL vault. Holds the SPL mint authority. Store / Retrieve only via CPI.
nacre_layer_ca	”Cold-account” registry. Maps Pearl reserve addresses to on-chain config.
nacre_layer_fee_management	Validator margin pool + protocol treasury.
nacre_protocol_config	Tunable parameters (fee bps, validator margin, pause flag, admin pubkeys).
nacre_validator_registry	Source of truth for which P-256 keys count toward the quorum.

Each program is independently upgradeable by the admin multisig, subject to a 14-day timelock for two_way_peg and liquidity_management.
