Create Account

Build a System Program instruction to create a new Solana account, with or without a seed.

Creates a new Solana account funded with lamports and assigned to an owner program.

This method returns a SolanaInstruction. Add it to a transaction and use the Transaction Service to execute it on-chain. See Instructions & Transactions.

Create

Creates a new Solana account funded with lamports and assigned to an owner program.

Request

payer · Base58-encoded public key (string) · required

The account paying for creation. Must be a signer.

new_account · Base58-encoded public key (string) · required

The new account’s public key. Must be a signer.

owner · Base58-encoded public key (string)

Program that will own the new account. Defaults to the System Program.

lamports · uint64 · required

Lamports to deposit into the new account. Must cover rent exemption. Use GetMinimumBalanceForRentExemption to calculate.

space · uint64 · required

Bytes to allocate for the account’s data. Use 0 for wallet accounts with no data.

Response

instruction · SolanaInstruction (object)

The System Program create_account instruction. Add to a transaction via CompileTransaction.

Code Examples

Go

resp, err := client.Create(ctx, &system_v1.CreateRequest{
    Payer:      "YOUR_PAYER_ADDRESS",
    NewAccount: "YOUR_NEW_ACCOUNT_ADDRESS",
    Owner:      "11111111111111111111111111111111",
    Lamports:   1_000_000,
    Space:      0,
})
if err != nil {
    log.Fatal(err)
}
// Add instruction to your transaction
instruction := resp.Instruction

---

CreateWithSeed

Creates an account at an address derived from a base public key and seed string. Useful when the account address must be deterministic.

Request

payer · Base58-encoded public key (string) · required

The account paying for creation. Must be a signer.

new_account · Base58-encoded public key (string) · required

The derived account address. Must match PublicKey.createWithSeed(base, seed, owner).

base · Base58-encoded public key (string) · required

Base public key used to derive new_account.

seed · string · required

Seed string (max 32 bytes) used to derive new_account.

lamports · uint64 · required

Lamports to deposit into the new account. Must cover rent exemption. Use GetMinimumBalanceForRentExemption to calculate.

space · uint64 · required

Bytes to allocate for the account’s data.

Response

instruction · SolanaInstruction (object)

The System Program create_account_with_seed instruction. Add to a transaction via CompileTransaction.

Code Examples

Go

resp, err := client.CreateWithSeed(ctx, &system_v1.CreateWithSeedRequest{
    Payer:      "YOUR_PAYER_ADDRESS",
    NewAccount: "YOUR_DERIVED_ACCOUNT_ADDRESS",
    Base:       "YOUR_BASE_ADDRESS",
    Seed:       "my-seed",
    Lamports:   1_000_000,
    Space:      165,
})
if err != nil {
    log.Fatal(err)
}
// Add instruction to your transaction
instruction := resp.Instruction
