Crossmint is bringing its full-stack stablecoin platform to Arc, combining embedded wallets, money movement, on/offramps, compliance tooling, and APIs for AI agents with Arc’s stablecoin-native execution environment. Together, they give developers a more direct path to building payments, remittances, embedded finance, and agent-led financial applications.

Pulsar founder and CEO Alex Radu shares how the team connects stablecoin funding, spending, trading, and rewards on Arc, with lessons for other builders.

We are still expanding our chapter community across priority markets, accepting applications for another round of contributor and leadership roles

Help shape Arc House’s resources, features, and community activities. We want to hear from people building apps, using products, learning about Arc and stablecoins, or simply exploring what’s possible.

On Arc, exchanges support one unified USDC asset for transfers and fees, without a separate gas-token balance to manage. Deposits can be credited after final inclusion, and withdrawals draw fees from the same asset being moved.

Fund a Gateway Unified Balance from a slow-finality EVM chain without waiting for that chain's Gateway deposit finality. In this Release Notes episode, HJ from Circle DevRel explains how chain finality shapes deposit latency, and how Fast Gateway Deposits in Unified Balance Kit and App Kit change the funding path. Blockchains confirm transactions at different speeds. When you deposit USDC into a Gateway Wallet, that deposit is only usable after the deposit chain reaches finality, often around 13 to 19 minutes on Ethereum, Base, or Arbitrum. A fast deposit can settle a crosschain USDC transfer within a minute: pass to and config.transferSpeed: "FAST", and the relayer handles the destination Gateway deposit.
