TrustSet

Creates or modifies a trust line allowing an account to hold issued currencies from a specific issuer.

See the canonical spec:

TypeScript
import { Client, Wallet } from 'xrpl';

async function setTrustLine(): Promise<void> {
  const client = new Client('wss://honeycluster.dev');
  await client.connect();

  const wallet = Wallet.fromSeed('s...');
  const prepared = await client.autofill({
    TransactionType: 'TrustSet',
    Account: wallet.address,
    LimitAmount: { currency: 'USD', issuer: 'r...issuer', value: '1000' },
    Flags: 0,
  });
  const signed = wallet.sign(prepared);
  const res = await client.submitAndWait(signed.tx_blob);
  console.log(res);
  await client.disconnect();
}

setTrustLine().catch(console.error);

Notes

•
Establishes a trust line for holding issued currencies
•
LimitAmount specifies the maximum amount you trust from this issuer
•
QualityIn and QualityOut control exchange rates
•
Flags can freeze the trust line or set other restrictions
•
Always use autofill to set fees and sequence safely when using the XRPL client library
