Holder Rewards and V1 Transactions Reach ZeroSlip
A combined release adds reward controls, a transaction format update and fixes.
ZeroSlip announced support for pump.fun’s holder rewards changes, while keeping older cashback tokens working. The update exposes holderRewardsRate and adds token creation controls through rewardFee and holderRewardsEnabled. For eligible quote mints other than WSOL or USDC, creators can configure additional fees of up to 3% for themselves or holders.
The release also moves ZeroSlip transactions to the V1 format. The announcement describes support for transactions up to 4 KB, allowing more operations to fit into a single Actions transaction, including buying a quote token before spending it on a target token.
Developers signing local transactions need a compatible Solana SDK. The update also fixes Data Stream and Trade API bugs, including failures affecting some Meteora DLMM and Pump AMM transactions. See the Trade API documentation.
