Buybacks

An enabled strategy receives its allocated WETH fee credits. The designated executor calls it to buy the same collection token in that collection’s canonical pool. The strategy can spend only cumulative payouts from its own fee vault, less what it has already spent.

The registered strategy’s WETH-input purchases are exempt from the hook fee, including sniper protection. This avoids a recursive fee loop. Recipient wallets, other pools, sales and arbitrary externally funded purchases are not exempt.

Do not send WETH directly to a buyback contract. Direct deposits cannot be spent or withdrawn.

In recipient mode, bought tokens go to the fixed destination. A treasury can accumulate token-backed NFTs through normal balance synchronization and later activate them itself. A distribution contract must implement its own reflections or claim logic.

In burn mode, the strategy calls the native token’s burn function. This is a real reduction in total supply, not just a transfer to an inaccessible address. It does not activate an earning NFT, and does not destroy another holder’s already activated NFT. The intermediate strategy address opts out of NFT materialization.

Only the designated executor can submit a buyback. Its threshold is a minimum spend, not a timer or automatic trigger. This release provides manual execution from the collection page and does not install an automated buyback keeper.

The interface simulates execution, applies a 0.5% minimum-output tolerance and expires the review after two minutes. The contract requires a positive minimum output and a deadline no more than five minutes ahead. The executor pays gas. Failed executions revert their fee claim and swap, leaving credits available for a retry.

1. Sign in as the configured executor.
2. Check available credited WETH and enter an eligible spend.
3. Review minimum output, destination or burn, and gas.
4. Confirm before the quote expires.

A keeper needs its own scheduling and gas budget. It must validate fair price, maximum price impact, slippage and MEV exposure before executing. The strategy’s minimum output and deadline do not supply an independent fair-price oracle.

Do not expose an endpoint that signs arbitrary caller-selected minimum outputs. The executor is trusted to select protective execution parameters. Large recipient transfers can hit the hybrid token’s per-transfer NFT synchronization bound; smaller executions or an explicitly compatible recipient may be needed.

Changing the fee allocation changes future funding, not the fixed recipient, route, executor or threshold. Check those settings carefully before launching.

A collection can combine the 1% base, 2% to a custom converter, 0.2% extra to its creator and 0.8% to buybacks. The ordinary total is 4%, within the 10% normal cap. All hook allocations are in WETH. The converter and reflection logic are separate contracts, not included merely by selecting these rates.
