Stablecoin 101

In this episode of Stablecoin 101, Elton Tay from the Developer Relations team introduces Circle Wallets, the gateway to building secure, flexible wallet experiences with USDC. 🔎 What you’ll learn: - Circle Wallet models: developer-controlled, user-controlled & modular - How Circle Wallets power storing, sending, and receiving USDC - The types of experiences each model can support

Gas shouldn’t get in the way of great user experiences. In this episode of Stablecoin 101, Blessing Adesiji breaks down how Circle Paymaster works — the onchain service that lets users pay gas fees with USDC instead of native tokens. Here’s what you’ll learn: - How Paymaster is built on account abstraction (ERC-4337) - How it makes transactions faster and simpler for users - Why this matters for developers building real-world onchain apps It’s a simple idea that removes one of the biggest barriers to onchain adoption — users can simply use USDC to send USDC, without ever worrying about gas.

Have you ever tried to send USDC onchain and realized you needed another token just to cover gas? That friction stops users before they even start. In this episode of Stablecoin 101, Blessing Adesiji breaks down how Circle Paymaster lets users pay network gas fees directly with USDC, making onchain payments simple, intuitive, and accessible. You’ll learn: - Why gas fees are a major user experience challenge - How Circle Paymaster lets you pay gas with USDC - How this improves adoption and accessibility for onchain apps - Use USDC to send USDC — no friction.

Both CCTP and Gateway move USDC across supported blockchains — but they do so in a different manner and solve different problems. In this episode of Stablecoin 101, Blessing Adesiji explains the key differences and helps developers and businesses understand which tool fits their needs. You’ll learn: - How CCTP powers secure, point-to-point USDC transfers - Why Gateway enables instant, unified balances across chains - How both products work together for seamless onchain liquidity Whether you’re moving funds between chains or building chain-abstracted apps, this episode makes it simple to choose a solution.

What if your USDC balance wasn’t tied to a single chain — but chain-abstracted and instantly available across supported chains at any time? That’s the value proposition of Circle Gateway. In this episode of Stablecoin 101, Blessing Adesiji breaks down how Gateway lets developers and users hold a single, unified USDC balance that can be accessed instantly across supported blockchains — without the need to bridge or swap. You’ll learn: - How Circle Gateway removes liquidity fragmentation across chains - Why it creates a smoother experience for users and businesses - How developers can build apps that just work — instantly, on any supported chain This is what it means to make money onchain feel as seamless as the internet itself.

How do you actually move USDC across blockchains in code? In this hands-on episode of Stablecoin 101, Blessing Adesiji walks through a real example of transferring USDC between testnets using CCTP (Cross Chain Transfer Protocol) — the infrastructure that powers seamless, secure, and fast onchain movement. You’ll learn: - How to set up your environment and connect to multiple chains - How USDC is burned, attested to, and minted using CCTP - How developers can implement this workflow in their own apps By the end, you’ll see how easy it is to integrate crosschain USDC transfers — and why CCTP is redefining interoperability for developers.

How fast can you move USDC across blockchains? With CCTP Fast Transfer, crosschain USDC transfers that once took minutes now complete in seconds. In this episode of Stablecoin 101, Blessing Adesiji explains how Circle’s latest upgrade makes “faster-than-finality” transfers possible — safely and securely. 💡 You’ll learn: - How CCTP Fast Transfer speeds up crosschain USDC movement - The role of Fast Transfer Allowance in helping to protect security and collateral - How developers can use Hooks to trigger automated onchain actions - Why this upgrade changes the experience of using USDC across ecosystems - Faster. Safer. This is what interoperability looks like in motion.

What if money could move across blockchains as easily as sending an email? That’s the power of USDC interoperability — and in this episode of Stablecoin 101, Blessing Adesiji (@bleso_a) breaks down how it works through a story-driven example featuring Alice, Bob, and a crosschain transfer powered by CCTP 💡 You’ll learn: - What interoperability really means in the world of USDC - How CCTP burns, verifies, and mints USDC across different blockchains - Why this matters for developers building wallets, apps, and DeFi protocols - This is how USDC connects blockchain ecosystems — securely, and seamlessly.
