Compose the retarder

Hook Builder

Couple validated presets into a single transfer hook, describe a transfer, and simulate it end to end. Every simulation returns the retarder sequence, the verdict, and the ExtraAccountMetaList the resolver would write for the composed hook.

Compose the hook0 selected

RoyaltyconditionalVerifies that a creator royalty is honored on every transfer; because a transfer hook only validates, the payment itself is collected through the Token-2022 transfer-fee extension or a paired escrow.

WhitelistproceedsPermits a transfer only when the counterparties are on an approved allowlist, failing every other transfer at the token-program level.

BlacklisthaltsHalts any transfer that touches a flagged address, failing the instruction before the tokens settle.

VestingconditionalBlocks transfers until an on-chain cliff has passed, then allows them to unlock linearly over a set duration.

AntiBotconditionalThrottles bursty activity by rejecting transfers that exceed a per-transfer size cap or arrive before a cooldown has elapsed.

KYCGateconditionalRequires each counterparty to hold a valid attestation from a named provider before a transfer is allowed to proceed.

FeeOnTransferconditionalEnforces a proportional fee condition on every transfer; the hook validates it while the Token-2022 transfer-fee extension or an escrow moves the fee.

SoulboundhaltsMakes the token non-transferable between wallets, allowing only mint and burn so holdings stay bound to their owner.

Select at least one preset to simulate.

Downloads hukt.json. Feed it to hukt build on the SDK page to generate the program config.

Connect a wallet to use your address as the transfer source.

Compose one or more presets and run a simulation to preview the retarder sequence, the overall verdict, and the ExtraAccountMetaList the resolver would write.
