SplitXCH Royalty Split Builder

Create complex XCH royalty distribution addresses from natural language descriptions.

How It Works

SplitXCH creates special Chia blockchain addresses that automatically split incoming payments to multiple recipients based on configured percentages. The API computes a puzzle address; any XCH sent to that address gets distributed automatically on-chain.

Workflow

1. Parse the user's plain-language split description into recipients with percentages
2. Convert percentages to basis points (scale to 9850 total, API adds 150 bps / 1.5% fee)
3. For nested splits (splits-of-splits), build bottom-up: create leaf splits first, then use their addresses as recipients in parent splits
4. Call the SplitXCH API via scripts/splitxch.sh or direct curl
5. Return the generated split address and a summary

Basis Points Conversion

• 10,000 bps = 100%. API fee = 150 bps (1.5%). Recipients get 9,850 bps total.
• Formula: points = round(percentage / 100 * 9850)
• Adjust last recipient so points sum to exactly 9850.

Example: "Split 60/40 between Alice and Bob"

• Alice: round(0.60 * 9850) = 5910
• Bob: 9850 - 5910 = 3940

Building the API Payload

{
  "recipients": [
    {"name": "Alice", "address": "xch1...", "points": 5910, "id": 1},
    {"name": "Bob", "address": "xch1...", "points": 3940, "id": 2}
  ]
}

Save to a temp file and run:

bash \x3Cskill_dir>/scripts/splitxch.sh /tmp/split-payload.json

Nested Splits (>128 recipients or hierarchies)

When the user describes groups within groups:

1. Create each leaf-level split first via the API
2. Use the returned address as a recipient in the parent split
3. Each split level incurs its own 150 bps fee

Example: "Team A (Alice 50%, Bob 50%) gets 70%, Charlie gets 30%"

1. Create Team A split: Alice 4925 + Bob 4925 = 9850 → returns xch1teamA...
2. Create parent split: TeamA address 6895 + Charlie 2955 = 9850

Validation Rules

• All addresses must start with xch1 and be valid bech32m
• Max 128 recipients per split
• All addresses unique within a split
• Each recipient's points > 0
• Points must sum to exactly 9850

Output Format

After creating a split, present:

1. Split Address: The generated xch1... address
2. Summary Table: Each recipient's name, address (truncated), and percentage
3. Fee Note: "SplitXCH takes a 1.5% platform fee per split level"
4. Usage: "Send XCH to this address and it will automatically distribute to all recipients"

If nested, show the full tree structure.

Important Notes

• The user MUST provide valid XCH wallet addresses for all recipients. If addresses are missing, ask for them before calling the API.
• If the user only provides names and percentages without addresses, list what's needed and ask.
• For dry runs / previews, show the calculated basis points without calling the API.
