We've introduced a rule that finds counter examples for all functions
that changes balances. This rule will always fail by definition, so
we're commenting it out to get CI green again.
There have been a bunch of breaking changes in the staking contract that
resulted in our specs not compiling.
This commit fixes this, however it does not yet ensure the prover is
satisfied.
This adds the `pnpm release` command to cut releases and generate
changelogs automatically from commit histories.
It also sets the `package.json` version to `0.1.0` as we haven't
actually put out a `1.0.0` release yet.
This is needed to deploy individual new `StakeManager` instances in
both, production environment and testing.
The script can be used as follows:
Within tests, to get a new `StakeManager` instance that has a reference
to an older `StakeManager` instance, run:
```solidity
function setUp() public virtual override {
super.setUp();
DeployMigrationStakeManager deployment = new DeployMigrationStakeManager(address(stakeManager), stakeToken);
newStakeManager = deployment.run();
}
```
Where `address(stakeManager)` is the address of the current
`StakeManager` and `stakeToken` is the address of the stake token.
To deploy a new instance from the CLI using `forge`, one can make use of
the `PREV_STAKE_MANAGER` and `STAKE_TOKEN_ADDRESS` environment variables
like this:
```sh
$ PREV_STAKE_MANAGER=0x123 STAKE_TOKEN_ADDRES=0x456 forge script script/DeployMigrationStakeManager.s.sol
```
The script will revert when `STAKE_TOKEN_ADDRESS` is `address(0)`.
Closes#71
This is to avoid getting these failing CI tasks where adding a PR to the
board fails when it was already added before (happens when pushing into
an existing PR).
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.
