Fee Sharing — Multi-Party Creator Fee Distribution

Configure and manage creator fee sharing — allowing token creators to distribute accumulated trading fees to multiple shareholders using the PumpFees program with BPS-based share allocation.

Workflow

1. Create Fee Sharing Config

const ix = PUMP_SDK.createFeeSharingConfig({
    creator, mint, pool, payer,
    shareholders: [
        { address: userA, shareBps: 5000 },  // 50%
        { address: userB, shareBps: 3000 },  // 30%
        { address: userC, shareBps: 2000 },  // 20%
    ]
});

2. Update Shareholders

const ix = PUMP_SDK.updateFeeShares({
    creator, mint,
    shareholders: [
        { address: userA, shareBps: 4000 },
        { address: userD, shareBps: 3000 },
        { address: userB, shareBps: 3000 },
    ]
});

3. Distribute Fees

const { instructions, isGraduated } = await onlineSdk.buildDistributeCreatorFeesInstructions(mint);
// For graduated: transferCreatorFeesToPump + distributeCreatorFees
// For non-graduated: distributeCreatorFees only

Validation Rules

Rule	Error Class
At least 1 shareholder	NoShareholdersError
Maximum 10 shareholders	TooManyShareholdersError
No zero-share entries	ZeroShareError
Shares sum to 10,000 BPS	InvalidShareTotalError
No duplicate addresses	DuplicateShareholderError
Graduated tokens need pool	PoolRequiredForGraduatedError

Patterns to Follow

• Validate shareholder arrays before sending: max 10, sum = 10,000 BPS, no duplicates, no zero shares
• Use BothPrograms methods when aggregating across Pump + PumpAMM
• Check isGraduated to determine if AMM fee consolidation is needed
• Check adminRevoked before attempting to update shareholders

Common Pitfalls

• Shares must total exactly 10,000 BPS (100%) — not 100, not 1,000,000
• Graduated tokens require the pool parameter for config creation
• Two separate creator vaults exist with different PDA seeds (hyphen vs underscore)
• updateFeeShares will fail on-chain if adminRevoked === true
• Basis points use integer arithmetic — fractional bps are not possible
