Jobs
To setup a locker function simply add the following modifier;
modifier keep() { require(LK3R.isLocker(msg.sender), "::isLocker: locker is not registered"); _; LK3R.worked(msg.sender);}
The above will make sure the caller is a registered locker as well as reward them with an amount of LK3R equal to their gas spent + premium. Make sure to have credit assigned in the Lock3r system for the relevant job.
Jobs can be created directly via governance or by submitting a job proposal to governance automatically via adding liquidity.
Simply create a new proposal via governance to add a new job
/** * @notice Allows governance to add new job systems * @param job address of the contract for which work should be performed */function addJob(address job) external;
You will need to provide liquidity to one of the approved liquidity pairs (for example LK3R-ETH). You put your LP tokens in escrow and receive credit. When the credit is used up, you can simply withdraw the LP tokens. You will receive 100% of the LP tokens back that you deposited.
/** * @notice Allows liquidity providers to submit jobs * @param liquidity the liquidity being added * @param job the job to assign credit to * @param amount the amount of liquidity tokens to use */function addLiquidityToJob(address liquidity, address job, uint amount) external
Jobs need credit to be able to pay lockers, this credit can either be paid for directly, or by being a liquidity provider in the system. If you pay directly, this is a direct expense, if you are a liquidity provider, you get all your liquidity back after you are done being a provider.
Step 1 is to provide LP tokens as credit. You receive all your LP tokens back when you no longer need to provide credit for a contract.
/** * @notice Allows liquidity providers to submit jobs * @param liquidity the liquidity being added * @param job the job to assign credit to * @param amount the amount of liquidity tokens to use */function addLiquidityToJob(address liquidity, address job, uint amount) external
Wait LIQUIDITYBOND (default 2 days) days.
/** * @notice Applies the credit provided in addLiquidityToJob to the job * @param provider the liquidity provider * @param liquidity the pair being added as liquidity * @param job the job that is receiving the credit */function applyCreditToJob(address provider, address liquidity, address job) external
/** * @notice Unbond liquidity for a job * @param liquidity the pair being unbound * @param job the job being unbound from * @param amount the amount of liquidity being removed */function unbondLiquidityFromJob(address liquidity, address job, uint amount) external
Wait UNBOND (default 14 days) days.
/** * @notice Allows liquidity providers to remove liquidity * @param liquidity the pair being unbound * @param job the job being unbound from */function removeLiquidityFromJob(address liquidity, address job) external
/** * @notice Add credit to a job to be paid out for work * @param credit the credit being assigned to the job * @param job the job being credited * @param amount the amount of credit being added to the job */function addCredit(address credit, address job, uint amount) external
/** * @notice Add ETH credit to a job to be paid out for work * @param job the job being credited */function addCreditETH(address job) external payable
Dependent on your requirements you might allow any lockers, or you want to limit specific lockers, you can filter lockers based on age, bond, total earned funds, or even arbitrary values such as additional bonded tokens.
Accept all lockers in the system.
/** * @notice confirms if the current locker is registered, can be used for general (non critical) functions * @param locker the locker being investigated * @return true/false if the address is a locker */function isLocker(address locker) external returns (bool)
Filter lockers based on bonded amount, earned funds, and age in system.
/** * @notice confirms if the current locker is registered and has a minimum bond, should be used for protected functions * @param locker the locker being investigated * @param minBond the minimum requirement for the asset provided in bond * @param earned the total funds earned in the lockers lifetime * @param age the age of the locker in the system * @return true/false if the address is a locker and has more than the bond */function isMinLocker(address locker, uint minBond, uint earned, uint age) external returns (bool)
Additionally you can filter lockers on additional bonds, for example a locker might need to have SNX to be able to participate in the Synthetix ecosystem.
/** * @notice confirms if the current locker is registered and has a minimum bond, should be used for protected functions * @param locker the locker being investigated * @param bond the bound asset being evaluated * @param minBond the minimum requirement for the asset provided in bond * @param earned the total funds earned in the lockers lifetime * @param age the age of the locker in the system * @return true/false if the address is a locker and has more than the bond */function isBondedLocker(address locker, address bond, uint minBond, uint earned, uint age) external returns (bool)
There are three primary payment mechanisms and these are based on the credit provided;
Pay via liquidity provided tokens (based on
addLiquidityToJob)Pay in direct ETH (based on
addCreditETH)Pay in direct token (based on
addCredit)
If you don't want to worry about calculating payment, you can simply let the system calculate the payment itself;
/** * @notice Implemented by jobs to show that a locker performed work * @param locker address of the locker that performed the work */function worked(address locker) external
The maximum amount that can be paid out per call is (gasUsed * fastGasPrice) * 1.1
/** * @notice Implemented by jobs to show that a locker performed work * @param locker address of the locker that performed the work * @param amount the reward that should be allocated */function workReceipt(address locker, uint amount) external
There is no limit on how many tokens can be paid out via this mechanism
/** * @notice Implemented by jobs to show that a locker performed work * @param credit the asset being awarded to the locker * @param locker address of the locker that performed the work * @param amount the reward that should be allocated */function receipt(address credit, address locker, uint amount) external
There is no limit on how many tokens can be paid out via this mechanism
/** * @notice Implemented by jobs to show that a locker performend work * @param locker address of the locker that performed the work * @param amount the amount of ETH sent to the locker */function receiptETH(address locker, uint amount) external
