• The variable 'payer' is declared earlier for the source chain and then re-declared for the destination chain. Consider renaming one of them (e.g. 'destPayer') to avoid confusion and potential scope issues.

Nice job! Just some minor adjustments when sharing the snippet. Super clear flow :)

I tried both with attested and non-attested tokens, and it is not returning anything. It doesn't crash either.

You have to take this part out of the function for it to work:
attestToken().catch((e) => { console.error('❌ Error in attestToken', e); process.exit(1); });

dawnkelly@Mac attest-token % npx tsx attest.ts
✅ Token already registered on destination: SolanaAddress {
type: 'Native',
address: PublicKey [PublicKey(BQeTpGLxxe7AkwssS1MS242tGguy1TZYNqUkjwuDq3Fr)] {
