◈ Roadmap

Where We're Going

A focused build path — unified stablecoin spend shipping today, an Auto-Replenish Agent in preview, then hardening agent and payment surfaces for mainnet readiness.

Q2 · 2026 · Now
◆
Public Beta + Agent Preview

Public beta on Arc Testnet with Unified Balance (wallet + Gateway as one selector), production CCTP V2 flows, EIP-6963 wallet detection — and the Auto-Replenish Agent in preview: EIP-2612 permit + Circle Programmable Wallet executor, daily cap, revocable anytime.

Q3 · 2026
◇
Agent v1 + Reliability

Graduate the Auto-Replenish Agent out of preview based on tester feedback. Multi-chain target wallets, richer schedule + threshold logic, agent execution observability, and reliability work across Gateway / CCTP V2 settlement paths.

Q4 · 2026
◈
Programmable Payments + Ecosystem

Broader programmable-payment surfaces on top of the agent stack, additional chain support (high-stablecoin-volume networks), spend analytics with B2B memo references, and production hardening for mainnet readiness.

2027 · Beyond
◉
StableFX & Arc Mainnet

RFQ-driven USDC ⇄ EURC PvP settlement via the Arc FxEscrow contract, deeper integration with the Circle Agent Stack, and Arc Mainnet launch when ready.
