Send tokens to any Spark address. Transfers are instant, free, and recipients receive them automatically.
Transfer Tokens

​
Send Tokens

const [tokenIdentifier] = await wallet.getIssuerTokenIdentifiers();
if (!tokenIdentifier) throw new Error("No token identifiers found for this issuer");

await wallet.transferTokens({
  tokenIdentifier,
  tokenAmount: 100_000000n, // 100 tokens (6 decimals)
  receiverSparkAddress: "spark1abc..."
});

​
Batch Transfer

Send to multiple recipients in a single transaction: 
await wallet.batchTransferTokens([
  { tokenIdentifier, tokenAmount: 1000_000000n, receiverSparkAddress: "spark1alice..." },
  { tokenIdentifier, tokenAmount: 500_000000n, receiverSparkAddress: "spark1bob..." },
  { tokenIdentifier, tokenAmount: 250_000000n, receiverSparkAddress: "spark1carol..." }
]);
Batch transfers are atomic. All succeed or none do. Each item in the array must include its own tokenIdentifier.

​
Token Amounts

All amounts are in base units. If your token has 6 decimals:
HumanBase Units
11,000,000
100100,000,000
0.5500,000
function toBaseUnits(amount: string, decimals: number): bigint {
  const [whole, fraction = ""] = amount.split(".");
  const fractionPadded = (fraction + "0".repeat(decimals)).slice(0, decimals);
  return BigInt(whole || "0") * 10n ** BigInt(decimals) + BigInt(fractionPadded || "0");
}

await wallet.transferTokens({
  tokenIdentifier,
  tokenAmount: toBaseUnits("50.5", 6),
  receiverSparkAddress: "spark1..."
});

​
Receiving Tokens

Recipients don’t need to do anything. Tokens appear instantly: 
const { tokenBalances } = await wallet.getBalance();

tokenBalances.forEach((data, key) => {
  console.log(data.tokenMetadata.tokenName, ":", data.ownedBalance);
});
