Usage

const SOL = require('like-solana')

const rpc = new SOL.RPC()
const user = new SOL.Keypair('<secret key...>')

const recentBlockhash = (await rpc.getLatestBlockhash()).blockhash

const ixTransfer = SOL.SystemProgram.transfer({
  fromPubkey: user.publicKey,
  toPubkey: user.publicKey,
  lamports: 0.0001337 * 1e9
})

const tx = SOL.sign(ixTransfer, { unitPrice: 0.0001, signers: [user], recentBlockhash })

const signature = await rpc.sendTransaction(tx)

console.log(signature)

API (static)

rpc = new SOL.Keypair([seed])

Generates or re-create a key pair from a seed.

Seed can be a String (base58), Buffer, or Uint8Array.

Seed can have both secret and public key or just the secret key.

Returns:

{
  publicKey, // PublicKey instance
  secretKey // Uint8Array
}

See solana-crypto for more detailed documentation on cryptography.

publicKey = new SOL.PublicKey(input)

Creates a PublicKey instance from an input.

Input can be a String (base58), Buffer, Uint8Array, or PublicKey.

publicKey.toString() returns it encoded as base58 string.

See solana-public-key for more detailed documentation on public keys and program-derived addresses.

rpc = new SOL.RPC([options])

Creates a new RPC instance to interact with the network.

Options:

{
  url: 'https://solana-rpc.publicnode.com',
  ws: 'wss://solana-rpc.publicnode.com',
  commitment: 'finalized'
}

See solana-rpc for more detailed documentation on networking.

tx = SOL.sign(instructions, options)

Sign a transaction.

Options:

{
  unitLimit: Number,
  unitPrice: Number, // E.g. 0.0001
  tip: Object, // E.g. { account, amount: 0.0001 }
  recentBlockhash: String,
  signers: Array, // Key pairs used to sign
  payer: String // Fee payer, uses first signer by default
}

Notice: Not compatible with versioned transactions for now.

txEncoded = SOL.toBase64(transaction)

Serialize a transaction into base64.

signature = SOL.signature(transaction)

Get the signature from a transaction (object or base64).
