Well account (one per well) PDA: [WELL, well_id] Tracks current auction state for a well

Fields

well_id: u64

Well ID (0-3) - which well this is for

epoch_id: u64

Current epoch ID (increments each auction: 0, 1, 2, 3, etc.) Starts at 0, increments when bid happens

current_bidder: Pubkey

Current bidder/owner (Pubkey::default() if unowned)

init_price: u64

Initial price for current epoch (in lamports) Doubles from current price when bid happens

mps: u64

Mining per second (MPS) - current mining rate (OIL per second, in atomic units) This is the base rate adjusted for halvings

epoch_start_time: u64

Epoch start time (timestamp when current epoch started)

accumulated_oil: u64

Accumulated OIL mined by current owner (not yet claimed)

last_update_time: u64

Last time accumulated_oil was updated

halving_count: u64

Number of halvings that have occurred (for rate calculation)

lifetime_oil_mined: u64

Total OIL ever mined from this well (lifetime)

is_pool_owned: u64

Flag indicating if owned by pool (1) or solo owner (0) When pool wins (pool_total >= current_price), this is set to 1

operator_total_oil_mined: u64

Total OIL mined by current operator (doesn’t reset when claimed, only when ownership changes) Repurposed from buffer_a

last_synced_epoch_id: u64

Last epoch ID that was synced (similar to checkpoint_id in Driller) Used to enforce sync_auction_state before set_bid (like checkpoint before deploy) Repurposed from buffer_b

buffer_c: u64

Buffer field (for future use)

buffer_d: u64

Buffer field (for future use)

buffer_e: u64

Buffer field (for future use)

Implementations

impl Well

pub fn pda(well_id: u64) -> (Pubkey, u8)

pub fn current_price(&self, auction: &Auction, clock: &Clock) -> u64

Calculate current price for this epoch (Dutch auction - price decreases over time)

pub fn update_accumulated_oil(&mut self, clock: &Clock)

Update accumulated OIL for this epoch state

pub fn check_and_apply_halving(&mut self, auction: &mut Auction, clock: &Clock)

Check and apply halving if needed, updating mining rate Time-based halving: halvings occur every 28 days (halving_period_seconds) Uses 50% reduction (multiply by 0.5) per halving, matching Macaron’s model

impl Well

pub fn to_bytes(&self) -> &[u8]

Trait Implementations

impl AccountValidation for Well

fn assert<F>(&self, condition: F) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_err<F>( &self, condition: F, err: ProgramError, ) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

impl Clone for Well

fn clone(&self) -> Well

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Well

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Well

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Discriminator for Well

fn discriminator() -> u8

impl PartialEq for Well

fn eq(&self, other: &Well) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Well

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Zeroable for Well

fn zeroed() -> Self

Calls zeroed.

impl Copy for Well

impl Pod for Well

impl StructuralPartialEq for Well
