+# @jito-foundation/stake-deposit-interceptor-sdk
+
+A TypeScript SDK for interacting with Jito's stake deposit interceptor program on Solana. This program acts as the `stake_deposit_authority` for SPL stake pools, implementing a time-decaying fee mechanism on LST (Liquid Staking Token) deposits.
+
+More information available in the [Jito governance forum](https://forum.jito.network/t/jip-9-adopt-interceptor-liquidity-defense/444).
+
+## Installation
+
+```bash
+npm install @jito-foundation/stake-deposit-interceptor-sdk
+# or
+yarn add @jito-foundation/stake-deposit-interceptor-sdk
+```
+
+## Key Features
+
+- 🛡️ **Time-Decaying Fees**: Implements fees that linearly decay to zero over a configurable period
+- 🔐 **Stake Pool Integration**: Acts as stake deposit authority for SPL stake pools
+- 🎫 **Deposit Management**: Handles stake deposits with receipt tracking
+- 🤖 **Automated Claims**: Permissionless cranking system for fee-free claims after cooldown
+- 📝 **Type Safety**: Fully typed TypeScript SDK
+
+## Important Concepts
+
+### Deposit Flow
+1. User deposits stake using `depositStake()` or `depositStakeWithSlippage()`
+2. Stake begins earning rewards immediately
+3. LST tokens are minted and held by the program
+4. User can either:
+   - Claim LST early with a fee
+   - Wait for cooldown and claim fee-free (can be automated by cranker)
+
+### Slippage Protection
+`depositStakeWithSlippage()` allows setting a minimum LST output to protect against unfavorable rate changes during transaction processing.
+
+## Program Accounts
+
+### StakePoolDepositStakeAuthority
+The main control account for the stake pool's deposit authority:
+```typescript
+interface StakePoolDepositStakeAuthority {
+    base: PublicKey;
+    stakePool: PublicKey;
+    poolMint: PublicKey;
+    authority: PublicKey;
+    vault: PublicKey;
+    stakePoolProgramId: PublicKey;
+    coolDownSeconds: BN;
+    initialFeeBps: number;
+    feeWallet: PublicKey;
+    bumpSeed: number;
+}
+```
+
+### DepositReceipt
+Tracks individual stake deposits and their associated parameters:
+```typescript
+interface DepositReceipt {
+    base: PublicKey;
+    owner: PublicKey;
+    stakePool: PublicKey;
+    stakePoolDepositStakeAuthority: PublicKey;
+    depositTime: BN;
+    lstAmount: BN;
+    coolDownSeconds: BN;
+    initialFeeBps: number;
+    bumpSeed: number;
+}
+```
+
+## Instructions
+
+### Stake Operations
+- `depositStake()`: Deposit stake into the pool, creating a deposit receipt
+- `depositStakeWithSlippage()`: Deposit stake with added slippage protection
+- `claimPoolTokens()`: Claim LST tokens (with fees if before cooldown)
+
+### Authority Management
+- `initStakePoolDepositStakeAuthority()`: Initialize the deposit authority for a stake pool
+- `updateStakePoolDepositStakeAuthority()`: Update authority parameters
+
+### Receipt Management
+- `updateOwner()`: Transfer deposit receipt ownership to a new address
