You can create wallets with a single line of code using the BitGo SDK.

Balances

Solana (SOL) is the native asset of the Solana blockchain. The base unit of Solana is a Lamport (1/1000000000) of 1 SOL coin:

• 1 Lamport is (10-9) or 0.000000001 SOL.
• 1 Solana is (109) or 1000000000 Lamport.

Balances are supported in string and number format but string is recommended to ensure values do not exceed the programmable number limit: balanceString, confirmedBalanceString, and spendableBalanceString.

Solana accounts have a fee to store data on the blockchain, which is referred to as "rent". In order to prevent accounts from paying rent, a minimum balance of 0.002447136 SOL is retained on Solana wallets to make them rent exempt. The minimum balance must stay on your wallet and cannot be spent.

Fee rate

Solana has a statically set base fee per signature, which is 5000 Lamport or 0.000005 SOL. This results in a fee of 0.000005 SOL for hot wallet transactions, and a fee of 0.00001 SOL for Custody/Cold wallet transactions.

Consolidation

In order to consolidate funds into your root address via SDK, you can use the following:

async function consolidate(walletId) {
  await bitgo.authenticateWithAccessToken({ accessToken });
  const unlock = await bitgo.unlock({ otp: '000000', duration: 3600 });
  if (!unlock) {
    console.log('We did not unlock.');
    throw new Error();
  }
  const walletInstance = await bitgo.coin(coin).wallets().get({ id: walletId });
  const consolidationTxs = await walletInstance.sendAccountConsolidations({
    walletPassphrase: walletPassphrase,
  });
}

Note: Consolidations for SOL have are limited to 500 addresses per transaction.
