QUESTION
While trying to set up a basic self-hosted unit testing environment (and CI) that tests this Chainlink VRF random number contract, I am experiencing slight difficulties in how to simulate any relevant blockchains/testnets locally.
For example, I found this repository that tests Chainlinks VRF. However, for default deployment it suggests/requires a free KOVAN_RPC_URL e.g. from Infura's site and even for "local deployment" it suggests/requires a free MAINNET_RPC_URL from e.g. Alchemy's site.
I adopted a unit test environment from the waffle framework which is described as:
Filestructure ...ANSWER
Answered 2021-Sep-09 at 04:35to test locally you need to make use of mocks which can simulate having an oracle network. Because you're working locally, a Chainlink node doesn't know about your local blockchain, so you can't actually do proper VRF requests. Note you can try deploy a local Chainlink node and a local blockchain and have them talk, but it isn't fully supported yet so you may get mixed results. Anyway, as per the hardhat starter kit that you linked, you can set the defaultNetwork to be 'hardhat' in the hardhat.config.js file, then when you deploy and run the integration tests (yarn test-integration), it will use mocks to mock up the VRF node, and to test the requesting of a random number. See the test here, and the mock contracts and linktoken get deployed here
QUESTION
I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:
...ANSWER
Answered 2021-Dec-13 at 14:56The blind-signature library used in the NodeJS code for blind signing implements the process described here:
BlindSignature.blind()generates the SHA256 hash of the message and determines the blind message m' = m * re mod N.BlindSignature.sign()calculates the blind signature s' = (m')d mod N.BlindSignature.unblind()determines the unblind signature s = s' * r-1 mod N.BlindSignature.verify()decrypts the unblind signature (se) and compares the result with the hashed message. If both are the same, the verification is successful.
No padding takes place in this process.
In the Java code, the implementation of signing the blind message in signConcealedMessage() is functionally identical to BlindSignature.sign().
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:

I am trying to sign a message in go generated via hd wallet's private key using cosmos sdk. Below is the equivalent implementation in python which generates the signed message / signature as expected when submitted/verified is working properly but unable to get it working wtih Go implementation. Any inputs for equivalent golang version of the python implementation is much appreciated. Thank you.
Python version uses sha256 , ecdsa but when using the equivalent cyrpto/ecdsa doesn't return valid signature.

QUESTION
I am developing game, which guesses number and get reward if they success. This is summary of my program. First, user send amount of sol and his guessing number. Second, Program get random number and store user's sol to vault. Third, Program make random number, if user is right, gives him reward.
Here, how can I check if the user sent correct amount of sol in program?
This is test code for calling program.
...ANSWER
Answered 2022-Jan-15 at 11:56The best solution would be to directly transfer the lamports inside of your program using a cross-program invocation, like this program: Cross-program invocation with unauthorized signer or writable account
Otherwise, from within your program, you can check the lamports on the AccountInfo passed, and make sure it's the proper number, similar to this example: https://solanacookbook.com/references/programs.html#transferring-lamports
The difference there is that you don't need to move the lamports.
QUESTION
Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.
I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.
How can you transfer SOL using the web3.js sdk for Solana?
How to transfer custom token by '@solana/web3.js'
according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:
- Create a @solana/web3.js Transaction object and add instructions to it
- Sign the transaction with the wallet
- Send the transaction over a Connection
But i am having difficulty finding examples or documentation as to how to do step 1 and 2.
...ANSWER
Answered 2021-Dec-06 at 13:51So i found a way to do this, it requires some cleanup and error handling but allows for a custom token transaction via @solana/wallet-adapter.

I am following this guide for signing HTTP requests to an Amazon OpenSearch Service using Node.js (version 3 of the AWS SDK for JavaScript).
When I copy the exact sample code and export my AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY of my authorised user, the PUT index/type/id request to add an item is successful:
ANSWER
Answered 2022-Jan-24 at 13:39i also had this issue, using the same tutorial
reading the docs on request body searches, i found it states the following:
Note The _search API accepts HTTP GET and POST for request body searches, but not all HTTP clients support adding a request body to a GET request. POST is the more universal choice.
changing my method to POST solved the issue for me

ANSWER
Answered 2022-Jan-04 at 15:24I have encountered the same error. I had not changed the contract address once I deployed it to the testnet(Previously I deployed to localhost). Just check if the contract address you are using is of the contract you deployed to the testnet.

Switched Link and VRF are probably the culprit.
