I am creating one app with functionality to import Ethereum chain wallets and solana wallets with keywords and PrivateKey.
For Ethereum chains, i successfully imported the wallet using entered Private Key. I want to do the same for Solana. I am creating Solana wallet address using https://github.com/ajamaica/Solana.kt this code's Account.kt class and also signing transactions and sending tokens using this. Can anyone help if is there any method to import Solana wallet using PrivateKey?
In the default constructor for the Account.kt class, it's generating a new keypair for you to use. If you want to import an existing keypair, you can use any of the other constructors, such as:
constructor(secretKey: ByteArray): https://github.com/ajamaica/Solana.kt/blob/1a79932e67e698f2dba5f347fb74dd47d702f8fb/solana/src/main/java/com/solana/core/Account.kt#L29fromJson(json: String): https://github.com/ajamaica/Solana.kt/blob/1a79932e67e698f2dba5f347fb74dd47d702f8fb/solana/src/main/java/com/solana/core/Account.kt#L94The secret key or JSON string parameter is the 64 bytes representing your private key, like:
[131,30,15,126,65,195,177,39,147,196,183,221,159,85,134,0,29,179,48,175,149,133,13,75,184,212,99,68,29,62,82,248,37,183,235,40,42,249,238,136,159,202,239,211,121,108,51,154,178,214,31,6,111,28,202,173,100,41,145,230,76,152,208,131]
Note that Solana and Ethereum are not perfectly compatible since they use different cryptographic curves. Solana uses the ed25519 curve for its accounts / keypairs, so your private key will be 64 bytes, whereas Ethereum uses the secp256k1 curve, meaning 32 bytes for your private key.
