The agentic era isn't coming. It's here. Agents will trade where the money is stable, the rules are onchain and your keys never leave your hands. That place already exists. FAZE. Only on @arc

USDC supply on @Arc rose $220M (+42%) over the last week, to $742M - that's the highest daily level since Arc's launch on Sep 16 👀 At the same time, @circle minted $891M of USDC on Arc and burned $671M, EURC supply fell from $7.4M to $6.9M and GBPA supply did not change. This new record high comes as DTCC plans to connect Arc to its tokenization service in 2027.

Extended moves to @arc on Thursday. Settlement migrates from Starknet to Arc on October 22 at 13:00 UTC. The migration is planned with no interruption to trading. Positions can still be liquidated during this time, so top up margin beforehand. Transfers between sub-accounts stay open. Most accounts need to do nothing. Your account, sub-accounts, positions, orders, history, points and keys carry across unchanged. USDC migrates as native USDC, ETH migrates 1:1 as wETH, and Vault (XVS) balances and withdrawal rights are preserved. If you hold more than $1 of USDT or wBTC in any sub-account, you must act by 12:00 UTC on October 21: - Authorise the conversion in-app. USDT converts to USDC and wBTC to cirBTC at 1:1 during the migration, with no swap fees. Extended credits a 0.50% premium. - Or withdraw both assets. If you miss the deadline, your whole account will be restricted for up to 30 minutes on October 21 while Extended cancels orders, closes positions in the affected sub-accounts at mark price with no fees, and returns your USDT and wBTC to your login wallet. Deposits and withdrawals will be paused for up to 2 hours during the migration. Full details can be found in the documentation: docs.extended.exchange/about…

WEEK 3 — ARC ACCELERATION SEASON The third week of the 6-week program with @Arc is done, where we're working with fintech and AI startups as they take their businesses to the next stage of growth on Arc. On Tuesday, the teams joined a product masterclass with Rocío Girado and Julieta Habif from @paisanos_io. Wednesday was set aside for mentoring sessions, and on Thursday we hosted public office hours at Arc House. Every startup also received feedback on their first deliverable this week, so we can keep working closely with each team on the goals they set for the rest of the program. A packed but incredible week!
WEEK 2 — ARC ACCELERATION SEASON The second week of the 6-week program with @Arc is done, where we're working with fintech and AI startups as they take their businesses to the next stage of growth on Arc. We opened the week with a group mentoring session, followed by a technical masterclass, Deep Dive in Arc, by @criptopoeta, Arc Country Lead. On Wednesday, the teams joined office hours with @bleso_a, DevRel at @Circle and Arc, and on Thursday, a second round with Tomás Cordero and @BrazillianCare.

There is one Arc Studio feature that, if you’re not using while building onchain, you’re debugging blind. It’s called Tracing. Let’s imagine you’re building an app that sends USDC. You click send and approve the transaction in your wallet, but your app is still loading. Now you’re not sure what’s going on. Did the wallet connect? Was the transaction submitted? Was it confirmed onchain? Did the contract emit the expected event? Instead of checking your browser console, wallet, and explorer separately, Tracing shows the full flow in one timeline. You can see every step, how long it took, where something failed, and the data your app sent and received. You could paste logs into an AI coding tool and ask it to debug them. But the real value of Tracing is that it automatically captures the full onchain flow first, so the AI has the right context to explain what happened. You can also click Ask Studio and let the AI explain the trace for you. Start building today at studio[dot]arc[dot]io

A sneak peek at the Tolly Agent Exchange, being built on @arc. As the agent economy grows, discovering services is only part of the challenge. Users and other agents will need ways to compare offerings, identify reliable providers, and understand what's actually happening across the ecosystem. Tolly Agent Exchange is being developed as a comprehensive discovery and analytics platform, bringing x402 service comparisons, agent directories, job and task tracking, and performance analytics together in one place. At the heart of the Exchange, independent operators will be able to establish public business profiles showcasing their agents' capabilities, services, pricing, and verifiable activity history. Bringing greater transparency to agent services, reputation, and economic activity on Arc.

Week 4 of the Arc Accelerator Program was an insightful session on finding product-market fit led by @Jib0xD, founder of @ryskfinance. We explored how stablecoins and programmable money can solve real-world problems, the importance of understanding user pain points, and how to validate demand early. It was a great learning experience that reinforced the importance of building products around real user needs rather than assumptions.
