This adds a test that ensures multiplier points are minted with a 1:1
ratio to the stake token amount.
This scenario covers the case where no lock up time is set during
staking.
Unstaking didn't actually work because it was using `transferFrom()` on the
`StakeVault` with the `from` address being the vault itself.
This would result in an approval error because the vault isn't creating
any approvals to spend its own funds.
The solution is to use `transfer` instead and ensuring the return value
is checked.
This commit introduces `MIN_LOCKUP_PERIOD` and `MAX_LOCKUP_PERIOD` and
makes use of them within `StakeManager.stake()` and
`StakeManager.lock()` accordingly.
When users deposit tokens into their vault via `stake()`, they can
provide an optional lockup time. If the value is `0` it implies users do
not want to lock their stake.
If the value is `> 0` it has to be within the range of
`MIN_LOCKUP_PERIOD` and `MAX_LOCKUP_PERIOD`.
Properly addresses #15
This commit introduces a first version of a `VaultFactory` that later
will be extended to be capable of instantiating reward vaults and
possible keep track of vault instances per owner.
As a first step, this implementation comes with a `createVault()`
function which takes care of creating vaults.
Because `VaultFactory` also knows about `StakeManager` it can derive the
manager's address and stake token from it when creating vaults, allowing
the API to be without arguments.
Partially addresses #37
Because the `stakedToken` property is `immutable`, solhint recommends to
make it in all caps. This commit changes the property to adhere to that
rule and also makes the property private.
To access the `stakedToken` there's now a `stakedToken()` function on
the contract.
This was kept around as I wasn't sure if this was still needed but now
that we've removed the legacy folder and are aiming for adding SNT as a
vendor dependency it's most likely no longer needed.
If we still need something like that, we'd implement it as foundry
script.
This commit migrates the repo to our foundry template, which ensures we
have consistent tooling across smart contract repositories that are
maintained by Vac.
This removes all hardhat related files and workflows and replaces them
with more perfomant foundry workflows.
It also sets up tests, CI and linting.
- Now, MPs are minted on the newly staked amount only (previously was entire stake).
- The bonus MPs are calculated correctly such that there is a 1x bonus per year of lock.
- Still TBD: MPs are not minted for existing stake if current lock extended (or newly introduced), there is no check for max boost MP ceiling
