When additional funds are added to an existing vault (top-up), a new cliff period can be defined specifically for those new tokens, allowing for flexible and complex vesting schedules. + +## Architecture + +### Core Components + +#### 1. Vault Model +- **Purpose**: Represents a single vesting vault +- **Key Fields**: + - `address`: Smart contract address + - `token_address`: Address of the token being vested + - `owner_address`: Vault owner + - `total_amount`: Cumulative tokens deposited + +#### 2. SubSchedule Model +- **Purpose**: Individual vesting schedule for each top-up +- **Key Fields**: + - `vault_id`: Reference to parent vault + - `top_up_amount`: Amount of tokens in this top-up + - `cliff_duration`: Cliff period in seconds + - `vesting_duration`: Total vesting period in seconds + - `start_timestamp`: When vesting begins (cliff end) + - `end_timestamp`: When vesting completes + - `amount_withdrawn`: Track withdrawals from this sub-schedule + +#### 3. Beneficiary Model +- **Purpose**: Track beneficiaries and their allocations +- **Key Fields**: + - `vault_id`: Reference to parent vault + - `address`: Beneficiary wallet address + - `total_allocated`: Total tokens allocated + - `total_withdrawn`: Total tokens withdrawn + +## API Endpoints + +### Vault Management + +#### Create Vault +```http +POST /api/vaults +Content-Type: application/json + +{ + "address": "0x1234567890123456789012345678901234567890", + "name": "Employee Vesting Vault", + "token_address": "0xabcdefabcdefabcdefabcdefabcdefabcdefabcd", + "owner_address": "0x1111111111111111111111111111111111111111", + "initial_amount": "10000", + "beneficiaries": [ + { + "address": "0x2222222222222222222222222222222222222222", + "allocation": "5000" + } + ] +} +``` + +### Top-Up Operations + +#### Process Top-Up with Cliff +```http +POST /api/vaults/{vaultAddress}/top-up +Content-Type: application/json + +{ + "amount": "5000", + "cliff_duration_seconds": 2592000, // 30 days + "vesting_duration_seconds": 7776000, // 90 days + "transaction_hash": "0xabcdef1234567890", + "block_number": 12345, + "timestamp": "2024-01-01T00:00:00Z" +} +``` + +### Vesting Information + +#### Get Vesting Schedule +```http +GET /api/vaults/{vaultAddress}/schedule?beneficiaryAddress={address} +``` + +#### Calculate Withdrawable Amount +```http +GET /api/vaults/{vaultAddress}/{beneficiaryAddress}/withdrawable?timestamp={timestamp} +``` + +#### Process Withdrawal +```http +POST /api/vaults/{vaultAddress}/{beneficiaryAddress}/withdraw +Content-Type: application/json + +{ + "amount": "1000", + "transaction_hash": "0xwithdraw123456", + "block_number": 12346, + "timestamp": "2024-02-01T00:00:00Z" +} +``` + +#### Get Vault Summary +```http +GET /api/vaults/{vaultAddress}/summary +``` + +## Vesting Logic + +### Cliff Calculation + +1. **Before Cliff**: No tokens are vested +2. **During Cliff**: No tokens are vested +3. **After Cliff**: Linear vesting begins + +### Vesting Formula + +``` +if now < cliff_end: + vested_amount = 0 +elif now >= vesting_end: + vested_amount = top_up_amount +else: + vested_ratio = (now - cliff_end) / (vesting_end - cliff_end) + vested_amount = top_up_amount * vested_ratio +``` + +### Multiple Top-Ups + +Each top-up creates an independent SubSchedule with its own: +- Cliff period +- Vesting duration +- Start/end timestamps +- Withdrawal tracking + +Total withdrawable amount = Sum(withdrawable from all sub-schedules) + +## Use Cases + +### 1.
