Proglet: borrow without selling

Reference

Addresses, accounts, instructions, constants, errors and events of the Proglet program, as the SDK exposes them.

PDAs

configPda()	["config"]	Global config: admin, crank authority, treasury, borrow_paused.
poolPda(mint)	["pool", mint]	The coin's pool. Its lamports are the SOL reserve.
poolTokenVault(mint)	ATA(pool, mint)	Token-2022 account holding the pool's tokens, collateral and set-aside tokens.
teamFeeVaultPda(pool)	["team_fee", pool]	The pool's share of fees for the team, swept to the treasury.
creatorPda(mint)	["creator", mint]	The coin's pump.fun creator: collects its creator fees for buybacks.
positionPda(pool, owner)	["position", pool, owner]	A wallet's loan on one coin.

Accounts

Decode raw account data with decodePool, decodePosition and decodeGlobalConfig, or fetch with the client.

Pool

mint, tokenProgram	PublicKey	The coin and its token program (Token-2022).
solReserve, tokenReserve	bigint	The AMM reserves. Counters kept by the program, never read from balances.
crankBufferSol, crankBufferToken	bigint	Liquidity waiting to join the reserves at the pool's ratio.
totalDebt, totalCollateral, totalLoanReserveToken	bigint	Lending totals.
createdSlot, lastSwapSlot	bigint	When the pool got its first liquidity, and its last swap.
observations, oracleHead	Observation[]	The price oracle: one pre-swap price per active slot (16 slots).
lendingOpen	boolean	Derived: SOL reserve >= 0.1 SOL.

Position

owner, pool	PublicKey	Who borrowed, from which pool.
collateral	bigint	Tokens locked.
debt	bigint	Lamports owed. Never grows: no interest.
loanReserveToken	bigint	Tokens the pool set aside with the loan; they return on repay.
openedSlot	bigint	Slot of the last borrow; repay opens MIN_LOAN_SLOTS later.

Instructions

swap(is_buy, amount_in, min_out)	anyone	Builder: `swapInstructions`.
quote_swap(is_buy, amount_in)	read-only	Simulate for an on-chain quote: `quoteSwapInstruction`.
create_token(name, symbol, uri)	anyone	Launch a coin: `createTokenInstruction`.
borrow(collateral, debt, max_fee_bps)	owner	Open or add to a loan: `borrowInstruction`.
repay()	owner	Repay all: `repayInstruction`.
repay_partial(amount)	owner	Repay part: `repayPartialInstruction`.
liquidate()	anyone	Close an unhealthy loan for a bonus: `liquidateInstruction`.
absorb()	anyone	Close an underwater loan: `absorbInstruction`.
sweep()	anyone	Move team fees to the treasury: `sweepInstruction`.
seed_liquidity, crank_buyback, crank_buyback_amm	crank	Buybacks and first liquidity; only the crank authority.
initialize_config, update_config	admin	Set the crank authority, treasury and the new-loan pause.

Any instruction can be built from the bundled IDL with buildInstruction(name, accounts, args).

SWAP_FEE_BPS	100n	Swap fee: 1%.
TEAM_SHARE_BPS	2000n	Team share of the swap fee: 20%.
MIN_POOL_SOL_FOR_LENDING	100000000n	Pool depth for lending: 0.1 SOL.
MAX_LTV_BPS	4000n	Max loan: 40% of collateral value.
LIQUIDATION_RATIO_BPS	15000n	Liquidatable when collateral < 1.5x debt.
BORROW_CAP_BPS	1500n	A pool lends at most 15% of its SOL.
MIN_DEBT_LAMPORTS	10000000n	Minimum loan: 0.01 SOL.
LENDING_COOLDOWN_SLOTS	150n	New pools wait this long before lending.
SAFE_PRICE_MIN_AGE_SLOTS	10n	How old a price must be to count as safe.
MIN_LOAN_SLOTS	2n	A loan is repayable this many slots after it changes.
FEE_MIN_BPS / FEE_KINK_BPS / FEE_MAX_BPS	100n / 300n / 1000n	Borrow fee at empty, 80% used and full cap.
BONUS_MIN_BPS / BONUS_MAX_BPS	250n / 1500n	Liquidation bonus range.

SlippageExceeded	6004	Output is below min_out
ZeroLiquidity	6005	Liquidity amount is zero after keeping the pool ratio
NothingToSweep	6006	Nothing to sweep
TransferAmountMismatch	6007	Token amount received by the vault differs from the amount sent
InvalidBuybackAmount	6008	Buyback spend is zero or above the hard cap
InsufficientCreatorFunds	6009	Creator PDA does not hold enough SOL
NoTokensBought	6010	Buyback received no tokens
BuybackPriceDeviation	6011	pump.fun buyback price deviates too far from the pool's safe price
NotCanonicalPool	6012	Not the coin's canonical PumpSwap pool
BorrowPaused	6013	New loans are paused
LendingClosed	6014	Pool is below the minimum depth for lending
LendingCooldown	6015	Pool is too new for lending
DebtTooSmall	6016	Loan is below the minimum size
LtvExceeded	6017	Loan exceeds the max loan-to-value
BorrowCapExceeded	6018	Loan would exceed the pool's borrow cap
FeeAboveMax	6019	Fee is above the caller's max_fee_bps
RepayTooEarly	6020	Loan is too new to repay
NotLiquidatable	6021	Position is healthy
NotUnderwater	6022	Collateral still covers the debt

Events

The program emits Anchor events (base64 Program data: log lines). The Data API decodes them for you.
