GitHub Removes Malicious Pull Requests Targeting Open Source Repositories
GitHub removed 27 malicious pull requests attempting to inject harmful code across multiple open source repositories, in another round of low-effort attacks.

This is for withdrawing from your DCA account.
By default, output tokens are sent to you account automatically.
Withdraw is useful if you want to partially withdraw the input token but would still like to continue the DCA.
Or if for some reason, the output token was not sent to you automatically, you can use this instruction to withdraw them at anytime.
If you want to stop the DCA completely, use `closeDCA` instead (see below).

getAllByUser
to getCurrentByUser
. This method name reflects more accurately the return value of the method -> returns all active DCA accounts (not closed)getClosedByUser
. This method returns DCA Accounts that are already closed and not returned by getCurrentByUser
.
getClosedByUser
returns different values from getCurrentByUser
because it is no longer on the blockchain. E.g.:
[

createdAt: <BN: 64820460>,
updatedAt: <BN: 6487378a>,
userKey: [PublicKey [PublicKey(EKnD4oLXP3B2uDigQiUmQHEBX6fBt33kJBWjQRmVgpXB)]],

getFillHistory
e.g. getFillHistory(closedDcaAccounts[0].publicKey)
trackDca
. Not meant to be used directly. This automatically gets called when creating a new DCA account so that our tracker keeps a off chain record of the DCA Account data and maintain its data even after the dca account has been deleted on-chainFAQs
This SDK is an abstraction to interact with Jup's DCA Program.
We found that @jup-ag/dca-sdk demonstrated a healthy version release cadence and project activity because the last version was released less than a year ago. It has 6 open source maintainers collaborating on the project.
