sign transaction in react-native

[AmazingBeerBelly]

Hi,

I have developed algorand wallet in react-native, and I find I can't sign the transaction in ios simulator. I find the problem is Buffer.from(). I run the test code in the node env and I can send the transaction. I have compared the transaction's blob and find the node's transaction's blob is different from the react-native's transaction's blob. How should I solve this problem?

thanks a lot.

can you post a sample of the code where this failing?

async sendTx(mnemonic, amount, toAddr) {
const algodclient = new algosdk.Algod(token, server, port)
const recoveredAccount = algosdk.mnemonicToSecretKey(mnemonic)
const params = await algodclient.getTransactionParams()
const endRound = params.lastRound + parseInt(1000, 10)
const txn = {
from: recoveredAccount.addr,
to: toAddr,
fee: 1000,
amount,
firstRound: params.lastRound,
lastRound: endRound,
genesisID: params.genesisID,
genesisHash: params.genesishashb64,
note: new Uint8Array(0),
}
const signedTxn = algosdk.signTransaction(txn, recoveredAccount.sk)
// signedTxn.blob's length is 247 in node, and 767 in react native.
// I have found result of the Buffer.from() is different.
const tx = (await algodclient.sendRawTransaction(signedTxn.blob))
return tx
},

And I have an error when generating an account in react native without "Debug JS Remotely" mode.

code:
const account = algosdk.generateAccount()

then it reports errors "[Error: no PRNG]"

I believe this is an issue with Native React's lack of support for Crypto facebook/react-native#22933 . This is not a model we support currently

Ok, I will follow the react native issue. Thank you very much.
