Granted
GRANT LAYER
Scored routes. Your signature.
Routes are scored on hook permissions and deployed bytecode before Universal Router calldata is assembled. Coverage includes ETH, USDG, and tokenized equities. $GRANT sets the access tier and the fee schedule.
On-chain quote
The Robinhood Chain v4 quoter returns the number with hook deltas already inside it.
Hook score
Fourteen permission bits, then bytecode. Upgrade slots and SELFDESTRUCT score zero.
Route rank
Output, safety, and gas share one order. A cleaner hook can beat a slightly larger print.
Calldata
V4_SWAP, SETTLE_ALL, and TAKE_ALL are packed for the Universal Router before you sign.
Live pools
ETH, USDG, and tokenized equities. StateView refreshes liquidity as Initialize logs arrive.
$GRANT tiers
A larger balance widens the candidate set and applies the scheduled fee discount.
Layer surface
Eight live controls.
02 / Safety
Fourteen permission bits, then the bytecode. Upgrade slots and SELFDESTRUCT force a zero score.

Access token. A higher balance widens the candidate pool set, extends multi-hop depth, and applies the scheduled fee discount.
Settlement path
You keep the keys.
01
Index the pools
The index stores PoolKey, pool id, and liquidity. Initialize logs from the PoolManager extend the seed.
