    Hey, I was wondering if you guys had heard back from Reddit yet regarding your submission? Anything at all or still on standby?

    Reddit is currently evaluating all the submissions, we are in touch with them.

    Hey there, seems like ropsten zksync doesn't work, I sent few transactions today to deposit sync from ethereum and sync balance still nothing, ropsten zkscan also is silent

    @nbailo
    Is it connected with ropsten reorg?

    Hey
    Do you have https://wallet.zksync.io/ open sourced? Would love to add QRCODE reader in it

    Hi - can anyone here help with withdrawing Gitcoin grant money that is stuck in ZKsync with a Gnosis Safe wallet? Thanks
    is this Gitter active? Am i even in the right place?

    There is a separate zksync one here https://gitter.im/matter-labs/zksync, but in short there are public functions in the contract like getBalanceToWithdraw and corresponding WithdrawERC20 and WithdrawETH that you can use to get the available withdraw values for your Ethereum address and proceed with the withdraw. I assume you did trigger the withdraw procedure from the zksync itself and funds are now held by Ethereum contract

    Hi @shamatar thanks for the info. sorry, i have not triggered anything. I believe the funds are still on ZKsync, which is where they ended up during Gitcoin Grants round.
    Alexander
    @shamatar
    Then you would need to trigger the withdraw first using the wallet interface. In any case use a zksync channel or a discord’s zksync channel for a conversation

    Hello Team, need to know the rerequisites to run the zkSync setup on an Amazon Linux EC2 instance as I'm facing issues with "zksync init". A detailed setup document on Amazon Linux EC2 instance will be much appreciated. Thanks

    who can i speak with regarding these attack claims: https://medium.com/matter-labs/zkrollup-vs-validium-starkex-5614e38bc263
    specifically.. the zkp creates is suppose to cover the changeset for balances, and so if operator would have modified the merkle tree by adding balances the zkp would be invalidated no? see
    https://www.reddit.com/r/ethereum/comments/i01sjk/starkwares_submission_to_reddits_scaling_bakeoff/ and they explain : "STARK proof attesting to their integrity, and writes to Ethereum the proof, a commitment to the updated user balances data structure, and the modified user balances."

    Hi, I'm experimenting with bellman_ce's plonk support (in the beta branch) and found that depending on whether I have the wasm or multicorefeature set in Cargo.toml, the value of proof.opening_at_z_omega_proof differs. With multicore, it's valid, and invalid with wasm.

    Hello guys! Who is the best person / group of people to speak to when we have some integration proposal? Our solution enables easy migration from L1->L2 and cross-chain (it's a substrate palette).
