Keepers

Permissionless keepers. No discretion but the route.

A keeper watches books with the rule on and submits the sweep. The program computes the slice, checks the fill against Pyth, and writes the receipt; the keeper cannot change any of it. Anyone can run one.

Scrip runs 2 keepers, racingdevnet

Keeper 1FKfq2A…woJb — reporting just now, 0 sweeps

Keeper 2E73zEB…oJ8s — reporting just now, 0 sweeps

Different keys, the same open-source process. Whichever lands a sweep first writes the receipt; the other’s transaction fails, because the program refuses to sweep the same arrival twice. 2 of 2 reporting now.

What a keeper can and cannot dothe sweep, instruction by instruction

Cannot choose the amountthe program computes the slice from on-chain state

Cannot skip the checkbegin_sweep refuses unless finish_sweep follows in the same transaction

Cannot redirect the outputthe owner’s own token account is verified before and after

Only discretion: the routeinside the owner’s tolerance against Pyth, net of confidence

Only reward: the tip0.0005 SOL plus the receipt’s rent, from the owner’s float

Run one

git clone <this repository>
npm install
SCRIP_KEEPER_KEYPAIR=~/.config/solana/keeper.json \
PYTH_API_KEY=… \
NEXT_PUBLIC_SOLANA_CLUSTER=devnet \
npm run keeper

A keeper needs a little SOL for fees and a USDC account to pass the slice through. It earns the tip on every sweep it lands first. Two keepers racing is the design.
