Where We're Going

A focused build path — unifying stablecoin spend across chains, researching autonomous payment flows, then hardening for ecosystem rollout.

Q2 · 2026

Public Beta + Unified Spend

Launch ArcSwap public beta on Arc Testnet. Ship Unified Balance (wallet + Gateway as one selector), production CCTP V2 flows, and polished wallet UX with EIP-6963 detection.

Q3 · 2026
◇
Autonomous Stablecoin Ops · Research

Active research into how Agent Wallets, Unified Balance, native stablecoin conversion, and the emerging Circle Agent Stack can automate cross-chain routing, settlement, and execution on Arc. Direction shaped by user feedback.

Q4 · 2026
◈
Reliability + Ecosystem

Transaction reliability and observability, additional chain support (high-stablecoin-volume networks), spend analytics with B2B memo references, and production hardening for mainnet readiness.

2027 · Beyond
