Brief

Arc announced on 2026-06-18 that transaction memos and batched transactions are live on Arc Testnet, and that these features complement agentic payments and contracts. Transaction memos provide structured context—Invoice IDs, payout references, customer/ledger keys and memo events—to ease reconciliation, attribution, indexing and analytics, helping integrate onchain settlements with internal finance systems.

Crucial features for mapping the real world of payments and finance into onchain apps — memos and batched transactions — live on Arc Testnet.

Also powerful alongside agentic payments and contracts.

Onchain payments can settle instantly and still fall short if they are missing context.

Arc transaction memos add structured context to contract calls so payments, payouts, and financial activity are easier to reconcile, attribute, and connect to internal systems.

→ Invoice IDs
→ Payout references
→ Customer or ledger keys
→ Memo events for indexing and analytics

Fast settlement is only part of the job. Arc is built to make onchain finance usable.
